iOS 触摸 UIImageView

Question

  - (void)viewDidLoad
 {
  [super viewDidLoad];
// Do any additional setup after loading the view, typically from a nib.
   container = [[UIView alloc] initWithFrame:self.view.frame];
UIImageView* main_im0 = [[UIImageView alloc] initWithImage:[UIImage imageNamed:@"icon1.png"]];
[container addSubview:main_im0];
[self.view addSubview:container];

 }

 -(void)touchesBegan:(NSSet *)touches withEvent:(UIEvent *)event
{
UITouch *tt = [touches anyObject];

UIImageView *touchedview=(UIImageView*)[tt view];


NSArray *views = [container subviews];



 for (UIImageView* im in views)
 {
    UIImageView* focus=im;
    if (touchedview==focus)
    {

    }

}

我有一段代码，它设置了一个名为 main_im0 的 ImageView，它被放入一个 UIView 容器中，然后将其放入 View 中。当我点击 main_im0 时，我预计触摸功能会达到 touchedview==focus 的条件。但是，我无法激活该条件？怎么了？

Answer 1

请启用

main_im0.userInteractionEnabled = YES;

对于UIImageView，默认是No
