view.addGestureRecognizer(UITapGestureRecognizer(target: view, action: #selector(UIView.endEditing(_:))))

这里有很多关于使用UITapGestureRecognizer的很好的答案——所有这些都打破了UITextField的clear (X)按钮。解决方案是通过它的委托来抑制手势识别器:

- (BOOL)gestureRecognizer:(UIGestureRecognizer *)gestureRecognizer shouldReceiveTouch:(UITouch *)touch {
    BOOL touchViewIsButton = [touch.view isKindOfClass:[UIButton class]];
    BOOL touchSuperviewIsTextField = [[touch.view superview] isKindOfClass:[UITextField class]];
    return !(touchViewIsButton && touchSuperviewIsTextField);
}

这不是最可靠的解决方案，但对我来说很管用。

如果我得到你的权利，你想辞职键盘狡猾敲在文本字段之外，但你没有你的文本字段的引用。

试试这个;

Take global textField, lets call it reftextField Now in textFieldDidBeginEditing set referenced text field to - (void) textFieldDidBeginEditing:(UITextField *)textField{ reftextField = textField; } Now you can happily use on any button clock, (adding a transparent button on begin editing recomended) - (void)dismissKeyboard { [reftextField resignFirstResponder]; } Or for resigning done button try this. //for resigning on done button - (BOOL) textFieldShouldReturn:(UITextField *)textField{ [textField resignFirstResponder]; return YES; }

这一定是通过触摸外部隐藏键盘的最简单方法:

- (void)touchesBegan:(NSSet *)touches withEvent:(UIEvent *)event {
    [self.view endEditing:YES];    
}

(从如何解散键盘时，用户点击其他区域以外的文本框?)

最好是让你的UIView成为UIControl的一个实例(在界面构建器中)，然后连接他们的TouchUpInside事件来解散键盘方法。这个IBAction方法看起来像:

- (IBAction)dismissKeyboard:(id)sender {
    [aTextBox resignFirstResponder];
}

你可以为UiView创建类别并重写touchesBegan方法，如下所示。

这对我来说很好。这是一种集中解决这一问题的方法。

#import "UIView+Keyboard.h"
@implementation UIView(Keyboard)

- (void)touchesBegan:(NSSet *)touches withEvent:(UIEvent *)event
{
    [self.window endEditing:true];
    [super touchesBegan:touches withEvent:event];
}
@end
