如何在按钮和TouchUpInside上有两种不同的SWIPE方法？

如何解决如何在按钮和TouchUpInside上有两种不同的SWIPE方法？

| 我有一个视图，其中有几个大按钮，它们的设置如下：

SwipeButton* btn = [[[SwipeButton alloc] initWithFrame:CGRectMake(55,300,50)] autorelease];    
btn.tag = k;

[btn setBackgroundImage:[UIImage imageNamed:[Nsstring stringWithFormat:@\"titleBackground.png\"]] 
                                                              forState:UIControlStatenormal];
[btn   addTarget:self
          action:@selector(indexAction:)
forControlEvents:UIControlEventTouchUpInside];

我希望能够触摸这些按钮，然后触发indexAction方法，或者-如果识别出轻扫，则触发另一个方法。 我以为我可以继承UIButton的子类，但这并不是真正的解决方案，因为现在可以识别出滑动和点击，因此可以同时使用这两种方法。 有没有解决的办法？如何在没有刷卡的情况下优先安排刷卡的优先级，并且只允许在触摸屏上方进行刷卡？ 任何帮助将不胜感激。 这是我将UIButton子类化的方式：

#import \"SwipeButton.h\"

@implementation SwipeButton

- (void)touchesBegan:(NSSet *)touches withEvent:(UIEvent *)event {
    [super touchesBegan:touches withEvent:event];
    [self.superview touchesBegan:touches withEvent:event];
}

- (void)touchesMoved:(NSSet *)touches withEvent:(UIEvent *)event {

    [super touchesMoved:touches withEvent:event];
    [self.superview touchesMoved:touches withEvent:event];
}

-(void)touchesEnded:(NSSet *)touches withEvent:(UIEvent *)event {
    [super touchesEnded:touches withEvent:event];
    [self.superview touchesEnded:touches withEvent:event];

} 
@end

    

解决方法

我认为您不需要继承UIButton类。你为什么不尝试这样的事情：

UIButton *button = [UIButton buttonWithType:UIButtonTypeCustom];
UIImage *image = [UIImage imageNamed:@\"picture_0.png\"];
[button setImage:image forState:UIControlStateNormal];
[button setFrame:CGRectMake((applicationFrame.size.width - image.size.width)/2,applicationFrame.size.height/2,image.size.width,image.size.height)];
[button addTarget:self action:@selector(buttonTapped:) forControlEvents:UIControlEventTouchUpInside];

UISwipeGestureRecognizer *recognizer;

recognizer = [[UISwipeGestureRecognizer alloc] initWithTarget:self action:@selector(handleSwipeFrom:)];
[recognizer setDirection:UISwipeGestureRecognizerDirectionRight];
[recognizer setDelegate:self];
[[self view] addGestureRecognizer:recognizer];
[recognizer release];

recognizer = [[UISwipeGestureRecognizer alloc] initWithTarget:self action:@selector(handleSwipeFrom:)];
[recognizer setDirection:UISwipeGestureRecognizerDirectionLeft];
[recognizer setDelegate:self];
[[self view] addGestureRecognizer:recognizer];
[recognizer release];

然后，创建用于处理按钮上的轻击和滑动的方法：

// Prevent recognizing touches on the slider
- (BOOL)gestureRecognizer:(UIGestureRecognizer *)gestureRecognizer shouldReceiveTouch:(UITouch *)touch {

if ([touch.view isKindOfClass:[UIButton class]]) {
    return YES;
}
return NO;
}

-(void)handleSwipeFrom:(UISwipeGestureRecognizer *)recognizer {

if ([recognizer direction] == UISwipeGestureRecognizerDirectionLeft) {

    // Handle left swipe
    NSLog(@\"left swipe\");

} else {

    // Handle right swipe
    NSLog(@\"right swipe\");

}
}

- (void)buttonTapped:(id)sender {

NSLog(@\"button pressed\");

}

协议中声明了前面三个方法中的第一个，因此不要忘了说您的类正在实现该协议：

@interface MyViewController : UIViewController <UIGestureRecognizerDelegate>

它有效，我自己尝试过。希望能帮助到你！ ;）     ,看一下
