为什么我的常规点击被选为LongPresses？

Question

此代码一直工作，直到我将项目从ios4转换为ios6（+ ARC）并将我的xib文件换成故事板。现在，我所做的任何点击都被视为长按。

手势设置

- (void)viewDidLoad
{

[super viewDidLoad];

for(UIButton *button in buttons)
{
    UILongPressGestureRecognizer *longPressRecognizer = [[UILongPressGestureRecognizer alloc] initWithTarget:self action:@selector(longPressDetected:)];
    longPressRecognizer.minimumPressDuration = 1;
    longPressRecognizer.numberOfTouchesRequired = 1;
    [button addGestureRecognizer:longPressRecognizer];
}

}

LongPress方法

- (IBAction)longPressDetected:(UIGestureRecognizer *)sender 
{
    if (sender.state != UIGestureRecognizerStateBegan) 
    {
        NSLog(@"duplicate press cancelled");
        return;
    }
    NSLog(@"LongPress Received");
}

故事板

Answer 1

将代码替换为此，然后检查：

UILongPressGestureRecognizer *longPressRecognizer = [[UILongPressGestureRecognizer alloc]  initWithTarget:self action:@selector(longPressDetected:)];
longPressRecognizer.minimumPressDuration = 2.0;
longPressRecognizer.delegate = self;
[button addGestureRecognizer:longPressRecognizer];

Answer 2

根据您添加的屏幕截图，您已将故障板中的按钮链接到longPressDetected:。你需要在故事板中删除它，它会正常工作。

基本上它正在执行按钮动作，该动作也指向相同的方法。
