프로그래밍 방식으로 기본 UIButton을 작성하는 방법
UIButton프로그래밍 방식 으로 기본을 만들려면 어떻게 해야합니까? 예를 들어 내 뷰 컨트롤러에서 viewDidLoad메소드를 실행할 때 3 UIButton개가 동적으로 생성되고 해당 레이아웃 또는 속성이 설정됩니다.
여기 하나가 있습니다 :
UIButton *button = [UIButton buttonWithType:UIButtonTypeCustom];
[button addTarget:self
action:@selector(aMethod:)
forControlEvents:UIControlEventTouchUpInside];
[button setTitle:@"Show View" forState:UIControlStateNormal];
button.frame = CGRectMake(80.0, 210.0, 160.0, 40.0);
[view addSubview:button];
- (void)viewDidLoad {
[super viewDidLoad];
[self addMyButton]; // Call add button method on view load
}
- (void)addMyButton{ // Method for creating button, with background image and other properties
UIButton *playButton = [[UIButton buttonWithType:UIButtonTypeRoundedRect] retain];
playButton.frame = CGRectMake(110.0, 360.0, 100.0, 30.0);
[playButton setTitle:@"Play" forState:UIControlStateNormal];
playButton.backgroundColor = [UIColor clearColor];
[playButton setTitleColor:[UIColor whiteColor] forState:UIControlStateNormal ];
UIImage *buttonImageNormal = [UIImage imageNamed:@"blueButton.png"];
UIImage *strechableButtonImageNormal = [buttonImageNormal stretchableImageWithLeftCapWidth:12 topCapHeight:0];
[playButton setBackgroundImage:strechableButtonImageNormal forState:UIControlStateNormal];
UIImage *buttonImagePressed = [UIImage imageNamed:@"whiteButton.png"];
UIImage *strechableButtonImagePressed = [buttonImagePressed stretchableImageWithLeftCapWidth:12 topCapHeight:0];
[playButton setBackgroundImage:strechableButtonImagePressed forState:UIControlStateHighlighted];
[playButton addTarget:self action:@selector(playAction:) forControlEvents:UIControlEventTouchUpInside];
[self.view addSubview:playButton];
}
목표 -C
UIButton *but= [UIButton buttonWithType:UIButtonTypeRoundedRect];
[but addTarget:self action:@selector(buttonClicked:) forControlEvents:UIControlEventTouchUpInside];
[but setFrame:CGRectMake(52, 252, 215, 40)];
[but setTitle:@"Login" forState:UIControlStateNormal];
[but setExclusiveTouch:YES];
// if you like to add backgroundImage else no need
[but setbackgroundImage:[UIImage imageNamed:@"XXX.png"] forState:UIControlStateNormal];
[self.view addSubview:but];
-(void) buttonClicked:(UIButton*)sender
{
NSLog(@"you clicked on button %@", sender.tag);
}
빠른
let myButton = UIButton() // if you want to set the type use like UIButton(type: .RoundedRect) or UIButton(type: .Custom)
myButton.setTitle("Hai Touch Me", forState: .Normal)
myButton.setTitleColor(UIColor.blueColor(), forState: .Normal)
myButton.frame = CGRectMake(15, 50, 300, 500)
myButton.addTarget(self, action: "pressedAction:", forControlEvents: .TouchUpInside)
self.view.addSubview( myButton)
func pressedAction(sender: UIButton!) {
// do your stuff here
NSLog("you clicked on button %@", sender.tag)
}
스위프트 3 이상
let myButton = UIButton() // if you want to set the type use like UIButton(type: .RoundedRect) or UIButton(type: .Custom)
myButton.setTitle("Hi, Click me", for: .normal)
myButton.setTitleColor(UIColor.blue, for: .normal)
myButton.frame = CGRect(x: 15, y: 50, width: 300, height: 500)
myButton.addTarget(self, action: #selector(pressedAction(_:)), for: .touchUpInside)
self.view.addSubview( myButton)
func pressedAction(_ sender: UIButton) {
// do your stuff here
print("you clicked on button \(sender.tag)")
}
스위프트 UI
예를 들어 SwiftUI 개발자 포털 에서 단계별 구현을 얻습니다.
import SwiftUI
struct ContentView : View {
var body: some View {
VStack {
Text("Target Color Black")
Button(action: {
/* handle button action here */ })
{
Text("your Button Name")
.color(.white)
.padding(10)
.background(Color.blue)
.cornerRadius(5)
.shadow(radius: 5)
.clipShape(RoundedRectangle(cornerRadius: 5))
}
}
}
}
#if DEBUG
struct ContentView_Previews : PreviewProvider {
static var previews: some View {
ContentView()
}
}
#endif
프로그래밍 방식으로 컨트롤러의보기에 버튼을 추가하려면 다음을 사용하십시오.
-(void)viewDidLoad
{
UIButton * btn = [UIButton buttonWithType:UIButtonTypeRoundedRect];
btn.frame = CGRectMake(0, 0, 100, 50);
[btn setTitle:@"Hello, world!" forState:UIControlStateNormal];
[self.view addSubview:btn];
}
이 중 세 가지를 추가하려면 헹구고 반복하십시오.
여기서 UIButton을 동적으로 만들 수 있습니다.
//For button image
UIImage *closebtnimg = [UIImage imageNamed:@"close_btn.png"];
//Custom type button
btnclose = [[UIButton buttonWithType:UIButtonTypeCustom]retain];
//Set frame of button means position
btnclose.frame = CGRectMake(103, 257, 94, 32);
//Button with 0 border so it's shape like image shape
[btnclose.layer setBorderWidth:0];
//Set title of button
[btnclose setTitle:@"CLOSE" forState:UIControlStateNormal];
[btnclose addTarget:self action:@selector(methodname:) forControlEvents:UIControlEventTouchUpInside];
//Font size of title
btnclose.titleLabel.font = [UIFont boldSystemFontOfSize:14];
//Set image of button
[btnclose setBackgroundImage:closebtnimg forState:UIControlStateNormal];
어서, 2014 년이야! 왜 안되는 코드 블록 평가 할당 으로, 아직 사용되는 경향이 보여 그것은의 미래!
UIButton* button = ({
//initialize button with frame
UIButton* button = [[UIButton alloc] initWithFrame:({
CGRect frame = CGRectMake(10.0, 10.0, 200.0, 75.0);
frame;
})];
//set button background color
[button setBackgroundColor:({
UIColor* color = [UIColor colorWithRed:1.0 green:1.0 blue:0.0 alpha:1.0];
color;
})];
//set button title for state
[button setTitle:({
NSString* string = [NSString stringWithFormat:@"title words"];
string;
}) forState:({
UIControlState state = UIControlStateNormal;
state;
})];
//set selector
[button addTarget:self action:({
SEL select = @selector(method:);
select;
}) forControlEvents:({
UIControlEvents event = UIControlEventTouchUpInside;
event;
})];
//return button
button;
});
[self.view addSubview:button];
우와!
또는 다음과 같이 정확한 결과를 얻을 수 있습니다.
UIButton* button = [[UIButton alloc] initWithFrame:CGRectMake(10.0, 10.0, 200.0, 75.0)];
[button setBackgroundColor:[UIColor colorWithRed:1.0 green:1.0 blue:0.0 alpha:1.0]];
[button setTitle:@"title words" forState:UIControlStateNormal];
[button addTarget:self action:@selector(method:) forControlEvents:UIControlEventTouchUpInside];
[self.view addSubview:button];
'action:@selector(aMethod:)' 다음과 같은 방법을 작성하십시오.
- (void)aMethod:(UIButton*)button
{
NSLog(@"Button clicked.");
}
그것은 나를 위해 작동합니다. 감사. 캔사스
목표 -C
// Create the Button with RoundedRect type
UIButton *mybutton = [UIButton buttonWithType:UIButtonTypeRoundedRect];
// instend of "Click Me" you can write your own message/Label
[mybutton setTitle:@"Click Me" forState:UIControlStateNormal];
// create the Rectangle Frame with specified size
mybutton.frame = CGRectMake(10, 10, 300, 140); // x,y,width,height [self.view addSubview:mybutton];// add button to your view.
빠른
let button = UIButton(type: UIButtonType.System) as UIButton
button.frame = CGRectMake(100, 100, 100, 50)
button.backgroundColor = UIColor.greenColor()
button.setTitle("Test Button", forState: UIControlState.Normal)
self.view.addSubview(button)
이 코드를 사용하여 버튼을 만들고 다른 좌표로 2 번 더 반복하면 버튼을 누를 때 메소드 (myButtonClick)가 호출됩니다.
UIButton *editButton = [UIButton buttonWithType: UIButtonTypeCustom];
editButton.frame = CGRectMake(0, 0, width, height);
[editButton setBackgroundImage: editButtonImage forState: UIControlStateNormal];
[myButton addTarget:self action:@selector(myButtonClick:) forControlEvents:UIControlEventTouchUpInside];
editButton.adjustsImageWhenHighlighted = YES;
editButton.titleLabel.text = @"Edit";
editButton.titleLabel.textColor = [UIColor whiteColor];
editButton.titleLabel.textAlignment = UITextAlignmentCenter;
editButton.titleLabel.font = [UIFont fontWithName: @"Helvetica" size: 14];
[self.view addSubview: editButton];
-(void) myButtonClick:(NSString *)myString{
NSLog(@"you clicked on button %@", myString);
}

이 코드가 효과가 있기를 바랍니다.
생성자 인스턴스를 루프 안에 넣고 원하는 경우 배열에서 동적으로 이름을 추가 할 수 있습니다.
UIButton *button = [UIButton buttonWithType:UIButtonTypeRoundedRect];
[button addTarget:self
action:@selector(aMethod:)
forControlEvents:UIControlEventTouchUpInside];
[button setTitle:@"Show View" forState:UIControlStateNormal];
button.frame = CGRectMake(10.0, 100.0, 300.0, 20.0);

[btn addTarget:self action:selector forControlEvents:UIControlEventTouchUpInside];
[btn setTitle:title forState:UIControlStateNormal];
[btn setImage:image forState:UIControlStateNormal];
btn.backgroundColor = [UIColor clearColor];
btn.tag = tag;
return btn;
}
뷰에 추가 할 수 있습니다.
[self.view addSubview:[self addButton:nil :self.view.frame :@selector(btnAction:) :[UIImage imageNamed:@"img.png"] :1]];

세 개의 버튼을 만드는 예제입니다. 그들의 위치를 옮기십시오.
UIImage *buttonOff = [UIImage imageNamed:@"crysBallNorm.png"];
UIImage *buttonOn = [UIImage imageNamed:@"crysBallHigh.png"];
UIButton *predictButton = [UIButton alloc];
predictButton = [UIButton buttonWithType:UIButtonTypeCustom];
predictButton.frame = CGRectMake(180.0, 510.0, 120.0, 30.0);
[predictButton setBackgroundImage:buttonOff forState:UIControlStateNormal];
[predictButton setBackgroundImage:buttonOn forState:UIControlStateHighlighted];
[predictButton setTitle:@"Predict" forState:UIControlStateNormal];
[predictButton setTitleColor:[UIColor purpleColor] forState:UIControlStateNormal];
[predictButton addTarget:self action:@selector(buttonPressed:) forControlEvents:UIControlEventTouchUpInside];
[self.view addSubview:predictButton];
이 코드로 버튼을 만들 수 있습니다.
UIButton *btn = [UIButton buttonWithType:UIButtonTypeCustom];
[btn addTarget:self action:@selector(btnAction) forControlEvents:UIControlEventTouchDragInside];
[btn setTitle:@"click button" forState:UIControlStateNormal];
btn.frame = CGRectMake(50, 100, 80, 40);
[self.view addSubview:btn];
버튼 동작 방법은 다음과 같습니다
-(void)btnAction
{
NSLog(@"button clicked");
}

Swift 3부터는 구문이 몇 가지 변경되었습니다.
Swift 3에서 기본 버튼을 만드는 방법은 다음과 같습니다.
let button = UIButton(type: UIButtonType.system) as UIButton
button.frame = CGRect(x: 100, y: 100, width: 100, height: 50)
button.backgroundColor = UIColor.green
button.setTitle("Example Button", for: UIControlState.normal)
self.view.addSubview(button)
이전 버전의 Swift 이후에 변경된 사항은 다음과 같습니다.
let button = UIButton(type: UIButtonType.System) as UIButton
// system no longer capitalised
button.frame = CGRectMake(100, 100, 100, 50)
// CGRectMake has been removed as of Swift 3
button.backgroundColor = UIColor.greenColor()
// greenColor replaced with green
button.setTitle("Example Button", forState: UIControlState.Normal)
// normal is no longer capitalised
self.view.addSubview(button)
시도 해봐....
UIButton *finalPriceBtn=[UIButton buttonWithType:UIButtonTypeRoundedRect];
finalPriceBtn.frame=CGRectMake(260, 25, 45, 15);
[finalPriceBtn addTarget:self action:@selector(goBtnClk:) forControlEvents:UIControlEventTouchUpInside];
finalPriceBtn.titleLabel.font=[UIFont systemFontOfSize:12];
[finalPriceBtn setTitle:[NSString stringWithFormat:@"$%.2f",tempVal] forState:UIControlStateNormal];
finalPriceBtn.titleLabel.textColor = [UIColor colorWithRed: 2.0f/255.0f green: 155.0f/255.0f blue: 213.0f/255.0f alpha:1];
finalPriceBtn.titleLabel.textAlignment=UITextAlignmentLeft;
[imageView addSubview:finalPriceBtn];
내가 도와줬으면 좋겠다.
UIButton *custombutton = [UIButton buttonWithType:UIButtonTypeRoundedRect];
[custombutton addTarget:self
action:@selector(aMethod:)
forControlEvents:UIControlEventTouchUpInside];
[custombutton setTitle:@"Click" forState:UIControlStateNormal];
custombutton.frame = CGRectMake(80.0, 110.0, 160.0, 40.0);
custombutton.titleLabel.textColor = [UIColor colorWithRed: 2.0f/255.0f green: 155.0f/255.0f blue: 213.0f/255.0f alpha:1];
[custombutton setImage:[UIImage imageNamed:@"hh.png"] forState:UIControlStateNormal];
[view addSubview:custombutton];
이 시도:
먼저 이것을 viewcontroller의 .h 파일에 작성하십시오.
UIButton *btn;
이제 이것을 viewcontrollers viewDidLoad의 .m 파일에 작성하십시오.
btn=[[UIButton alloc]initWithFrame:CGRectMake(50, 20, 30, 30)];
[btn setBackgroundColor:[UIColor orangeColor]];
[btn setTitle: @"My Button" forState:UIControlStateNormal];
[btn setTitleColor: [UIColor blueVolor] forState:UIControlStateNormal];
[btn.layer setBorderWidth:1.0f];
[btn.layer setBorderColor:[UIColor BlueVolor].CGColor];
//adding action programatically
[btn addTarget:self action:@selector(btnClicked:) forControlEvents:UIControlEventTouchUpInside];
[self.view addSubview:btn];
이것을 뷰 컨트롤러의 .m 파일에 viewDidLoad 메소드 외부에 작성하십시오.
- (IBAction)btnClicked:(id)sender
{
//Write a code you want to execute on buttons click event
}
대한 스위프트 3 (심지어 짧은 코드)
let button = UIButton(type: UIButtonType.custom)
button.frame = CGRect(x: 0, y: 0, width: 200.0, height: 40.0)
button.addTarget(nil, action: #selector(tapButton(_:)), for: UIControlEvents.touchUpInside)

button.setBackgroundImage(UIImage(named: "ImageName"), for: UIControlState.normal)
button.setTitle("MyTitle", for: UIControlState.normal)

기본적으로 두 가지 유형 의 버튼이 있습니다.
1) 시스템 종류 버튼
2) 커스텀 타입 버튼 (커스텀 타입 버튼에서는 버튼의 배경 이미지를 설정할 수 있습니다)
이 두 가지 유형의 버튼에는 제어 상태 가 거의 없습니다 https://developer.apple.com/documentation/uikit/uicontrol/state
중요한 상태는
1) 정상 상태
2) 선택된 상태
3) 강조된 상태
4) 비활성화 상태 등
//For system type button
let button = UIButton(type: .system)
button.frame = CGRect(x: 100, y: 250, width: 100, height: 50)

button.setTitleColor(.white, for: .normal)
button.titleLabel?.font = UIFont.boldSystemFont(ofSize: 13.0)
button.titleLabel?.textAlignment = .center//Text alighment center
button.titleLabel?.numberOfLines = 0//To display multiple lines in UIButton
button.titleLabel?.lineBreakMode = .byWordWrapping//By word wrapping
button.tag = 1//To assign tag value
button.btnProperties()//Call UIButton properties from extension function
button.addTarget(self, action:#selector(self.buttonClicked), for: .touchUpInside)
self.view.addSubview(button)
//For custom type button (add image to your button)
let button2 = UIButton(type: .custom)
button2.frame = CGRect(x: 100, y: 400, width: 100, height: 50)
// button2.backgroundColor = .blue
button2.setImage(UIImage.init(named: "img.png"), for: .normal)

button2.btnProperties()//Call UIButton properties from extension function
button2.addTarget(self, action:#selector(self.buttonClicked), for: .touchUpInside)
self.view.addSubview(button2)
@objc func buttonClicked(sender:UIButton) {
print("Button \(sender.tag) clicked")
}
//You can add UIButton properties using extension
extension UIButton {
func btnProperties() {
layer.cornerRadius = 10//Set button corner radious
clipsToBounds = true
backgroundColor = .blue//Set background colour
//titleLabel?.textAlignment = .center//add properties like this
}
}
UIButton *btnname = [UIButton buttonWithType:UIButtonTypeRoundedRect];
[btnname setTitle:@"Click Me" forState:UIControlStateNormal];
btnname.frame = CGRectMake(10, 10, 100, 140);
[self.view addSubview:btnname];
