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UITableView和UIButtons。
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......
// ------------------------------------------------------
#pragma mark keyboard visual management
// ------------------------------------------------------
- (void) keyboardShow: (NSNotification*) n {
if (!keyboardIsVisible){
self->_oldContentInset = self.tvPayments.contentInset;
self->_oldIndicatorInset = self.tvPayments.scrollIndicatorInsets;
self->_oldOffset = self.tvPayments.contentOffset;
NSDictionary* d = [n userInfo];
CGRect r = [[d objectForKey:UIKeyboardFrameEndUserInfoKey] CGRectValue];
r = [self.tvPayments convertRect:r fromView:nil];
CGRect f = self.fr.frame;
CGFloat y =
CGRectGetMaxY(f) + r.size.height -
self.tvPayments.bounds.size.height + 5;
if (r.origin.y < CGRectGetMaxY(f)) {
NSNumber* duration = d[UIKeyboardAnimationDurationUserInfoKey];
NSNumber* curve = d[UIKeyboardAnimationCurveUserInfoKey];
[UIView animateWithDuration:duration.floatValue
delay:0
options:curve.integerValue << 16
animations:^{
CGRect b = self.tvPayments.bounds;
b.origin = CGPointMake(0, y);
self.tvPayments.bounds = b;
} completion: nil];
}
UIEdgeInsets insets = self.tvPayments.contentInset;
insets.bottom = r.size.height;
self.tvPayments.contentInset = insets;
insets = self.tvPayments.scrollIndicatorInsets;
insets.bottom = r.size.height;
self.tvPayments.scrollIndicatorInsets = insets;
keyboardIsVisible = YES;
}
}
- (void) keyboardHide: (NSNotification*) n {
if (keyboardIsVisible){
NSNumber* duration = n.userInfo[UIKeyboardAnimationDurationUserInfoKey];
NSNumber* curve = n.userInfo[UIKeyboardAnimationCurveUserInfoKey];
[UIView animateWithDuration:duration.floatValue
delay:0
options:curve.integerValue << 16

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);
}
