在需要給圖片，表徵圖等控制項添加 點擊效果，手勢效果的UITapGestureRecognizer用法

直接看程式碼範例：

- (void)viewDidLoad {    [super viewDidLoad];    // Do any additional setup after loading the view, typically from a nib.    UIImageView *imgView =[[UIImageView alloc] initWithFrame:CGRectMake(0, 0,320,100)];    imgView.backgroundColor = [UIColor redColor];    //因為沒有設定image屬性，為了顯示出圖片覆蓋地區    imgView.userInteractionEnabled=YES;    UITapGestureRecognizer *singleTap =[[UITapGestureRecognizer alloc]initWithTarget:self                                                                              action:@selector(onClickImage)];    [imgView addGestureRecognizer:singleTap];    [self.view addSubview:imgView];}

//處理單指事件- (void)handleSingleFingerEvent:(UITapGestureRecognizer *)sender{    if(sender.numberOfTapsRequired == 1) {        //單指單擊        NSLog(@"單指單擊");    }    else if(sender.numberOfTapsRequired == 2){        //單指雙擊        NSLog(@"單指雙擊");    }}//處理雙指事件- (void)handleDoubleFingerEvent:(UITapGestureRecognizer *)sender {    if(sender.numberOfTapsRequired == 1) {        //雙指單擊        NSLog(@"雙指單擊");    }    else if(sender.numberOfTapsRequired == 2){        //雙指雙擊        NSLog(@"雙指雙擊");    }}
