提供一下三種方法參考:
方法一:
- //單擊事件
- -(void)fun1
- {
- NSLog(@"click1");
- }
- //雙擊事件
- -(void)fun2
- {
- NSLog(@"click2");
- }
- //單擊和雙擊方法之一
- -(void)touchesBegan:(NSSet *)touches withEvent:(UIEvent *)event
- {
- if ([[touches anyObject] tapCount] == 1) {
- [self performSelector:@selector(fun1) withObject:nil afterDelay:1];
- }
- else if ([[touches anyObject] tapCount] ==2)
- {
- [NSObject cancelPreviousPerformRequestsWithTarget:self selector:@selector(fun1) object:nil];
- [self performSelector:@selector(fun2) withObject:nil afterDelay:1];
- }
- }
方法二:[線程]
- int num = 0;
- -(void)fun1
- {
- [NSThread sleepForTimeInterval:1];
- if(num == 1)
- {
- NSLog(@"click 1");
- }
- }
- -(void)fun2
- {
- [NSThread sleepForTimeInterval:1];
- if(num == 2)
- {
- NSLog(@"click 2");
- }
- }
- -(void)touchesBegan:(NSSet *)touches withEvent:(UIEvent *)event
- {
- if([[touches anyObject] tapCount] == 1)
- {
- num = 1;
- NSThread * thread = [[NSThread alloc] initWithTarget:self selector:@selector(fun1) object:nil];
- [thread start];
- }
- else if([[touches anyObject] tapCount] == 2)
- {
- num = 2;
- NSThread * thread = [[NSThread alloc] initWithTarget:self selector:@selector(fun2) object:nil];
- [thread start];
- }
- }
方法三:[利用手勢控件本身自帶的方法]
原理:執行第二個方法的時候,取消第一次的方法操作
- - (void)viewDidLoad
- {
- [super viewDidLoad];
- //點擊事件
- UITapGestureRecognizer *tap = [[UITapGestureRecognizer alloc] initWithTarget:self action:@selector(fun1)];
- //單點觸摸
- tap.numberOfTouchesRequired = 1;
- //點擊幾次,如果是1就是單擊
- tap.numberOfTapsRequired = 1;
- [self.view addGestureRecognizer:tap];
- UITapGestureRecognizer *tap2 = [[UITapGestureRecognizer alloc] initWithTarget:self action:@selector(fun2)];
- tap2.numberOfTapsRequired = 2;
- [self.view addGestureRecognizer:tap2];
- //如果滿足第二次 第一次的就取消
- [tap requireGestureRecognizerToFail:tap2];
- }
