UISegmentcontrol 항목을 변경하면 IOS 5에서 customBadge가 숨겨집니다.

Question

UISegmentControl에 사용자 정의 배지를 추가했습니다. Xcode 4.0.2 SDK 4.3에서 잘 작동합니다. 그러나 Xcode 4.2 SDK 5.0에서 다른 항목을 선택하면 맞춤 배지가 표시되지 않습니다. 왜 이런 일이 일어날 지 모르겠다. 나는 IOS 4.3 Xcode 4.0.2에 대해 다음 코드를 사용하고 있습니다 : 다른

- (void)viewDidLoad { 
    [super viewDidLoad]; 

    super.tableView.backgroundView = [[UIImageView alloc] initWithImage:[UIImage imageNamed:@"wallpaper.png"]]; 
    NSLog(@"Root View Loaded"); 

    segmentedControl = [[UISegmentedControl alloc] initWithItems: 
              [NSArray arrayWithObjects: 
              @"Home",@"Surveys",@"Results",@"Create",@"Settings", 
              nil]]; 
    [segmentedControl addTarget:self action:@selector(segmentAction:) forControlEvents:UIControlEventValueChanged]; 
    segmentedControl.frame = CGRectMake(0, 0, 310, 40); 
    segmentedControl.segmentedControlStyle = UISegmentedControlStyleBar; 
    segmentedControl.tintColor = [UIColor darkGrayColor];

    [segmentedControl addSubview:surveyCountBadge];  
    if (surveycount == 0) { 
     [surveyCountBadge setHidden:YES]; 
    }else{ 
     [surveyCountBadge setHidden:NO]; 
    } 
} 
-(void)segmentAction:(id) sender{ 
    UISegmentedControl *segmentedControl = (UISegmentedControl *)sender;

    if (segmentedControl.selectedSegmentIndex == 0) {

     [self.navigationController pushViewController:settingsViewControlle animated:YES]; 
    } 


} 

모든 것은 나는이에 언급해야한다?

Answer 1

segmentedControl에 하위보기를 추가합니다. 다른 항목을 선택하면 시스템이 컨트롤을 다시 그리는 방법을 모르기 때문에 뷰를 제거할지 여부를 말할 수 없습니다. 컨트롤, 버튼 또는 segmentedControl이 작동하도록하고 배지를 추가하려면 부모의 하위 뷰로 추가하십시오.

[surveyCountBadge setFrame:CGRectMake(105.0f+segmentedControl.frame.origin.x, 
    -10.0f+sementedControl.frame.origin.y, surveyCountBadge.frame.size.width, 
    surveyCountBadge.frame.size.height)]; 

[[segmentedControl superView] addSubview: surveyCountBadge];
