我想知道如何使键盘消失时,用户触摸以外的UITextField。
当前回答
我试了这里的很多回答,都不太走运。我的点击手势识别器总是导致我的UIButtons在点击时不响应,即使我将手势识别器的cancelsTouchesInView属性设置为NO。
这就是最终解决问题的方法:
有一个ivar:
UITapGestureRecognizer *_keyboardDismissGestureRecognizer;
当文本字段开始编辑时,设置手势识别器:
- (void) textFieldDidBeginEditing:(UITextField *)textField
{
if(_keyboardDismissGestureRecognizer == nil)
{
_keyboardDismissGestureRecognizer = [[[UITapGestureRecognizer alloc]
initWithTarget:self
action:@selector(dismissKeyboard)] autorelease];
_keyboardDismissGestureRecognizer.cancelsTouchesInView = NO;
[self.view addGestureRecognizer:_keyboardDismissGestureRecognizer];
}
}
窍门在于如何设置遣散键盘方法:
- (void) dismissKeyboard
{
[self performSelector:@selector(dismissKeyboardSelector) withObject:nil afterDelay:0.01];
}
- (void) dismissKeyboardSelector
{
[self.view endEditing:YES];
[self.view removeGestureRecognizer:_keyboardDismissGestureRecognizer];
_keyboardDismissGestureRecognizer = nil;
}
我猜有一些关于从触摸处理执行堆栈中获得dismissKeyboardSelector执行的东西…
其他回答
override func touchesBegan(touches: Set<NSObject>, withEvent event: UIEvent) {
super.view.endEditing(true)
super.touchesBegan(touches, withEvent: event)
}
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; }
藏品视图:
// the keyboard follows the dragging touch off screen, and may be pulled upward again to cancel the dismiss
collectionView.keyboardDismissMode = .interactive
// dismisses the keyboard when a drag begins
collectionView.keyboardDismissMode = .onDrag
这是一个很好的通用解决方案:
objective - c:
- (void)touchesBegan:(NSSet *)touches withEvent:(UIEvent *)event {
[self.view endEditing:YES];
}
迅速:
override func touchesBegan(touches: NSSet, withEvent event: UIEvent) {
self.view.endEditing(true)
}
基于@icodebuster解决方案:https://stackoverflow.com/a/18756253/417652
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
