Question

使用UITapGestureRecognizer和UIButton在iPhone应用程序中工作。我在self.view中添加了UITapGestureRecognizer。当我点击UIButton时，它不会调用它的动作，只是调用tapgesture动作。如何解决这个问题？有谁可以帮忙解决这个问题？

以下是-ViewDidLoad中的代码，

UITapGestureRecognizer *tapRecognizer = [[UITapGestureRecognizer alloc] initWithTarget:self action:@selector(handleTapFrom:)];
    [self.view addGestureRecognizer:tapRecognizer];
    [tapRecognizer release];

UIButton *infoButton1 = [UIButton buttonWithType:UIButtonTypeInfoDark];
    infoButton1.frame = CGRectMake(0, 5, 30, 30);
    infoButton1.tag = 1;
    infoButton1.opaque = YES;
    [infoButton1 addTarget:self action:@selector(infoAlert:) forControlEvents:UIControlEventTouchUpInside | UIControlEventTouchUpOutside];
    [toolBarView1 addSubview:infoButton1]; 

-(void) infoAlert:(id) sender
{
    NSLog(@"Get Info Alert"); // Here the control not calling..
}


-(void)handleTapFrom:(UITapGestureRecognizer *)recognizer
{    
    NSLog(@"%@",[NSString stringWithFormat:@"%d", recognizer.view.tag]); // Whenever i touch the button this method only calling.
}

请帮我解决这个问题。提前谢谢。

为什么没有人使用堆栈溢出或谷歌的精彩搜索？

这是最好的解决方案：在您声明了tapRecognizer之后（我指的是您在问题上的代码）添加以下内容：

  tapRecognizer.cancelsTouchesInView = NO;

UIButton Action不使用UITapGestureRecognizer iphone应用程序调用？
