내 응용 프로그램에서 두 개의 버튼이 하위보기로 추가 된 UIImageView를 사용하고 있습니다. 그러나 단추를 클릭하려고하면 응답하지 않습니다. 이 문제가 있거나 해결해야 할 이유가 있습니까?UIImageView에 추가 된 버튼이 응답하지 않습니다.
- (void)showPopover {
if (isClicked == NO) {
if (popover == nil) {
popover = [[UIImageView alloc] initWithImage:[UIImage imageNamed:@"Popover.png"]];
[popover setFrame:CGRectMake(190, -10, 132, 75)];
UIButton *btn1 = [UIButton buttonWithType:UIButtonTypeCustom];
[btn1 setFrame:CGRectMake(30, 30, 24, 24)];
[btn1 setBackgroundColor:[UIColor clearColor]];
[btn1 setImage:[UIImage imageNamed:@"Bookmark.png"] forState:UIControlStateNormal];
[btn1 addTarget:self action:@selector(addFav) forControlEvents:UIControlStateNormal];
[popover addSubview:btn1];
