问题描述

问 题

• (id)initWithFrame:(CGRect)frame
  {
  self = [super initWithFrame:frame];
  if (self) {

     imgView=[[UIImageView alloc] initWithFrame:CGRectMake(0.f, 0.f, 1024.f, 768.f)];
     imgView.autoresizingMask = UIViewAutoresizingFlexibleLeftMargin | UIViewAutoresizingFlexibleWidth | UIViewAutoresizingFlexibleRightMargin;
     imgView.backgroundColor=[UIColor clearColor];
     [imgView setImage:[UIImage imageNamed:@"tupian.jpg"]];
     [self addSubview:imgView];
     //[imgView.bringSubviewToFront];
  

     closeButton = [[UIButton alloc] initWithFrame:CGRectMake(900.f, 100.f , 40.f, 40.f)];
     closeButton.autoresizingMask = UIViewAutoresizingFlexibleLeftMargin | UIViewAutoresizingFlexibleRightMargin;
     [closeButton setTitle:@"touch" forState:UIControlStateNormal];
     [closeButton addTarget:self action:@selector(closeClick) forControlEvents:UIControlEventTouchUpInside];
     [closeButton setBackgroundImage:[UIImage imageNamed:@"close"] forState:UIControlStateNormal];
     [self addSubview:closeButton];
   

  }
  return self;
  }

• (void)layoutSubviews
  {
  [super layoutSubviews];

}

• (void)closeClick
  {

  NSLog(@" 广告");
  [self.ADViewDelegate addADView];
  [imgView removeFromSuperview];
  

}

解决方案

看看 self.userInteractionEnabled 是不是为 YES。
