用iamgeview 加手势代替

self.headimageview = [[UIImageView alloc] initWithFrame:CGRectMake(IPHONEWIDTH(13), statusRect.size.height+IPHONEWIDTH(16), IPHONEWIDTH(119), IPHONEWIDTH(119))];

self.headimageview.image=UIimageName(@"homeimages");

//    阴影

self.headimageview.layer.shadowColor = Colorgray.CGColor;

self.headimageview.layer.shadowOffset = CGSizeMake(2, 2);

self.headimageview.layer.shadowOpacity = 0.7;

self.headimageview.layer.shadowRadius = 3;//阴影半径，默认3

self.headimageview.userInteractionEnabled = YES; //响应点击

UITapGestureRecognizer *tapGesture = [[UITapGestureRecognizer alloc] initWithTarget:self action:@selector(showLeftMenu)];

[self.headimageview addGestureRecognizer:tapGesture];

[self.view addSubview:self.headimageview];

-(void)showLeftMenu{

}
