UISearchBar / 키보드 검색 버튼 제목 변경

UISearchBar 컨트롤에서 키보드의 검색 키 제목을 완료로 변경하는 방법이 있습니까?

---

tablesearchbar라는 검색 표시 줄의 경우 :

// Set the return key and keyboard appearance of the search bar
        for (UIView *searchBarSubview in [tableSearchBar subviews]) {

            if ([searchBarSubview conformsToProtocol:@protocol(UITextInputTraits)]) {

                @try {

                    [(UITextField *)searchBarSubview setReturnKeyType:UIReturnKeyDone];
                    [(UITextField *)searchBarSubview setKeyboardAppearance:UIKeyboardAppearanceAlert];
                }
                @catch (NSException * e) {

                    // ignore exception
                }
            }
        }

적어도 iOS 8의 경우 간단히 :

    [self.searchBar setReturnKeyType:UIReturnKeyDone];

iOS 7 베타 5부터 Run Loop의 답변이 작동하지 않았지만 다음과 같이 작동했습니다.

for(UIView *subView in [searchBar subviews]) {
    if([subView conformsToProtocol:@protocol(UITextInputTraits)]) {
         [(UITextField *)subView setReturnKeyType: UIReturnKeyDone];
    } else {
        for(UIView *subSubView in [subView subviews]) {
            if([subSubView conformsToProtocol:@protocol(UITextInputTraits)]) {
                [(UITextField *)subSubView setReturnKeyType: UIReturnKeyDone];
            }
        }      
    }
}

---

한 가지 더 유용한 힌트는 Run Loop 코드 ( "@try") 섹션에 있습니다.

이렇게하면 텍스트 필드가 비어있을 때 "완료"버튼이 활성화됩니다.

UITextField *tf = (UITextField *)searchBarSubview;
tf.enablesReturnKeyAutomatically = NO;

Swift가 UISearchBar의 리턴 키를 변경하려면

searchBar.returnKeyType = UIReturnKeyType.done

사용 가능한 열거 형은 다음과 같습니다.

public enum UIReturnKeyType : Int {

    case default
    case go
    case google
    case join
    case next
    case route
    case search
    case send
    case yahoo
    case done
    case emergencyCall
    @available(iOS 9.0, *)
    case continue
}

알림! searchBar가 첫 번째 응답자로 남아 있으면 returnKeyType을 변경 한 후 키보드를 닫고 다시 팝업하여 변경 사항을 확인해야합니다.

search.resignFirstResponder()
searchBar.returnKeyType = UIReturnKeyType.Done
search.becomeFirstResponder()

---

선택적 메서드가있는 프로토콜이므로 try-catching 대신 각 메서드를 개별적으로 테스트해야합니다.

for (UIView *searchBarSubview in searchBar.subviews)
{
    if ([searchBarSubview conformsToProtocol:@protocol(UITextInputTraits)])
    {
        // keyboard appearance
        if ([searchBarSubview respondsToSelector:@selector(setKeyboardAppearance:)])
            [(id<UITextInputTraits>)searchBarSubview setKeyboardAppearance:UIKeyboardAppearanceAlert];
        // return key 
        if ([searchBarSubview respondsToSelector:@selector(setReturnKeyType:)])
            [(id<UITextInputTraits>)searchBarSubview setReturnKeyType:UIReturnKeyDone];
        // return key disabled when empty text
        if ([searchBarSubview respondsToSelector:@selector(setEnablesReturnKeyAutomatically:)])
            [(id<UITextInputTraits>)searchBarSubview setEnablesReturnKeyAutomatically:NO];
        // breaking the loop when we are done
        break;
    }
}

This will work for iOS <= 6. For iOS >= 7, you need to loop in searchBar.subviews[0].subviews.

Since the Alert-style keyboards are semi-transparent, I can see my view behind it. It doesn't look very good since I have multiple elements behind the keyboard that makes it hard for the keys to stand out. I wanted an all-black keyboard.

So I animated a black UIImageView into position behind the keyboard when text is edited. This gives the appearance of an all-black keyboard.

- (void)textFieldDidBeginEditing:(UITextField *)textField {

    [UIView beginAnimations:nil context:nil];
    [UIView setAnimationDuration:0.25]; 

    blackBoxForKeyboard.frame = CGRectMake(0, 377, 320, 216);
    [UIView commitAnimations]; 

}

I tried all the solutions shown here, and none of them worked for my UISearchBar (xcode5 compiling for iOS7). I ended up with this recursive function which worked for me:

- (void)fixSearchBarKeyboard:(UIView*)searchBarOrSubView {

    if([searchBarOrSubView conformsToProtocol:@protocol(UITextInputTraits)]) {
        if ([searchBarOrSubView respondsToSelector:@selector(setKeyboardAppearance:)])
            [(id<UITextInputTraits>)searchBarOrSubView setKeyboardAppearance:UIKeyboardAppearanceAlert];
        if ([searchBarOrSubView respondsToSelector:@selector(setReturnKeyType:)])
            [(id<UITextInputTraits>)searchBarOrSubView setReturnKeyType:UIReturnKeyDone];
        if ([searchBarOrSubView respondsToSelector:@selector(setEnablesReturnKeyAutomatically:)])
            [(id<UITextInputTraits>)searchBarOrSubView setEnablesReturnKeyAutomatically:NO];
    }

    for(UIView *subView in [searchBarOrSubView subviews]) {
        [self fixSearchBarKeyboard:subView];
    }
}

I then called it like so:

_searchBar = [[UISearchBar alloc] init];
[self fixSearchBarKeyboard:_searchBar];

---

Just for covering all the iOS versions:

NSArray *subviews = [[[UIDevice currentDevice] systemVersion] floatValue] < 7 ? _searchBar.subviews : _searchBar.subviews[0].subviews;

for (UIView *subview in subviews)
{
    if ([subview conformsToProtocol:@protocol(UITextInputTraits)])
    {
        UITextField *textField = (UITextField *)subview;
        [textField setKeyboardAppearance: UIKeyboardAppearanceAlert];
        textField.returnKeyType = UIReturnKeyDone;
        break;
    }
}
