ios-UIImageView的觸控事件

UIImageView的觸控事件

下面這段代碼顯示圖片：

UIImageView *preArrowImage =[[UIImageView alloc]init ];
preArrowImage.image =[UIImage imageNamed:@"arrowprev.png"];
preArrowImage.frame = CGRectMake(20, 60, 10, 30);
[self.view addSubview:preArrowImage];

想要對preArrowImage 的觸控事件進行一些操作，怎麼實現？

最佳回答：

給preArrowImage添加tap 手勢

UITapGestureRecognizer *recognizer=[[UITapGestureRecognizer alloc]
                                      initWithTarget:self action:@selector(tapHandler:)];
        [preArrowImage addGestureRecognizer:recognizer];


-(void)tapHandler:(UITapGestureRecognizer *)recognizer {
     //...to do your logic
}
