先需要声明的是:UILabel或UIImageView的 userInteractionEnabled属性默认为no,也就是说默认不接受事件。
所以方法一:
label.userInteractionEnabled = YES;//设置userInteractionEnabled属性为yes。 UITapGestureRecognizer *labelTap = [[UITapGestureRecognizer alloc] initWithTarget:self action:@selector(labelTap:)];//初始化一个单击手势 [label addGestureRecognizer:labelTap];//给label添加单击手势
- (void)click:(UITapGestureRecognizer *)gesture{ }
方法二:添加一个他们的子类,重写view的touch方法
#import @interface untitled : UIImageView { } @end #import "untitled.h" @implementation untitled - (id)initWithFrame:(CGRect)frame {
if ((self = [super initWithFrame:frame])) {
// Initialization code
self.userInteractionEnabled=YES;
}
return self;
} -(void)touchesBegan:(NSSet *)touches withEvent:(UIEvent *)event
{ }
-(void)touchesMoved:(NSSet *)touches withEvent:(UIEvent *)event
{ }
-(void)touchesEnded:(NSSet *)touches withEvent:(UIEvent *)event
{ } - (void)dealloc {
[super dealloc];
} @end
在touch事件种添加你自己想要的操作就可以了
然后定义自己的image就用untitled就可以了
