我想知道如何使键盘消失时,用户触摸以外的UITextField。

这是
在本例中,aTextField是唯一的UITextField....如果有其他的uitextview,还有一点点事情要做。
// YourViewController.h
// ...
@interface YourViewController : UIViewController /* some subclass of UIViewController */ <UITextFieldDelegate> // <-- add this protocol
// ...
@end
// YourViewController.m
@interface YourViewController ()
@property (nonatomic, strong, readonly) UITapGestureRecognizer *singleTapRecognizer;
@end
// ...
@implementation
@synthesize singleTapRecognizer = _singleTapRecognizer;
// ...
- (void)viewDidLoad
{
[super viewDidLoad];
// your other init code here
[self.view addGestureRecognizer:self.singleTapRecognizer];
{
- (UITapGestureRecognizer *)singleTapRecognizer
{
if (nil == _singleTapRecognizer) {
_singleTapRecognizer = [[UITapGestureRecognizer alloc] initWithTarget:self action:@selector(singleTapToDismissKeyboard:)];
_singleTapRecognizer.cancelsTouchesInView = NO; // absolutely required, otherwise "tap" eats events.
}
return _singleTapRecognizer;
}
// Something inside this VC's view was tapped (except the navbar/toolbar)
- (void)singleTapToDismissKeyboard:(UITapGestureRecognizer *)sender
{
NSLog(@"singleTap");
[self hideKeyboard:sender];
}
// When the "Return" key is pressed on the on-screen keyboard, hide the keyboard.
// for protocol UITextFieldDelegate
- (BOOL)textFieldShouldReturn:(UITextField*)textField
{
NSLog(@"Return pressed");
[self hideKeyboard:textField];
return YES;
}
- (IBAction)hideKeyboard:(id)sender
{
// Just call resignFirstResponder on all UITextFields and UITextViews in this VC
// Why? Because it works and checking which one was last active gets messy.
[aTextField resignFirstResponder];
NSLog(@"keyboard hidden");
}
其他回答
只是使用这段代码在您的.m文件,它将辞职的文本字段,当用户点击文本字段之外。
-(void)touchesBegan:(NSSet *)touches withEvent:(UIEvent *)event{
[textfield resignFirstResponder];
}
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
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
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)
}
