篇首语:本文由小常识网(cha138.com)小编为大家整理,主要介绍了在键盘可见时,iOS按钮点击不会被触发?相关的知识,希望对你有一定的参考价值。

我有一个非常奇怪的问题,其中有UITableViewUIButtons

我的表包含3个部分,每个部分有1个原型单元格。最后一个类型包含4个按钮(其中2个触发连接到Web服务并触发segue进入下一页的过程)。我也有第一类UITextField内的UITableViewCell

我的逻辑工作正常,除了一个案例 - 当我在编辑内部并且我的键盘可见时 - 我进行滚动(不退出编辑模式)。当我按下两个按钮之一时,我只退出编辑模式 - 按钮没有被触发。

任何想法可能是什么原因?

我拦截Gesture Recognizer但是视图的标签是0 - 无论我将它设置为-1300。我用代码:

UIView *view = gestRecognzr.view;
NSLog(@"%d", view.tag);//By tag, you can find out where you had tapped.

我使用通知和以下代码显示键盘:

// Add code for keyboard management
[[NSNotificationCenter defaultCenter] addObserver:self
                                         selector:@selector(keyboardShow:)
                                             name:UIKeyboardWillShowNotification
                                           object:nil];
[[NSNotificationCenter defaultCenter] addObserver:self
                                         selector:@selector(keyboardHide:)
                                             name:UIKeyboardWillHideNotification
                                           object:nil];

......而且......

答案

如果您是按钮,则需要实现UIGestureRecognizerDelegate并绕过手势识别器操作。

- (BOOL)gestureRecognizer:(UIGestureRecognizer *)gestureRecognizer shouldReceiveTouch:(UITouch *)touch {
    return (touch.view != yourButton);
}

访问https://developer.apple.com/library/ios/documentation/UIKit/Reference/UIGestureRecognizerDelegate_Protocol/index.html#//apple_ref/occ/intfm/UIGestureRecognizerDelegate/gestureRecognizer:shouldReceiveTouch
