我想知道如何使键盘消失时,用户触摸以外的UITextField。
当前回答
override func touchesBegan(touches: Set<NSObject>, withEvent event: UIEvent) {
super.view.endEditing(true)
super.touchesBegan(touches, withEvent: event)
}

objective - c:
在ViewController中添加这段代码。M文件:
-(void)touchesBegan:(NSSet *)touches withEvent:(UIEvent *)event
{
[self.view endEditing:YES];
}
迅速:
override func touchesBegan(_ touches: Set<UITouch>, with event: UIEvent?) {
view.endEditing(true)
}

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");
}
如果视图被嵌入到UIScrollView中,那么你可以使用以下方法:
tableView.keyboardDismissMode = UIScrollViewKeyboardDismissModeOnDrag;
tableView.keyboardDismissMode = UIScrollViewKeyboardDismissModeInteractive;
前者会在表格视图滚动时将键盘动画化,后者会像股票消息应用程序一样隐藏键盘。
注意,这些都可以在iOS 7.0或更高版本上使用。
发送消息resignFirstResponder的文本文件,把它放在那里。请参阅这篇文章了解更多信息。
对于那些在Swift中挣扎的人。这是Jensen2k在Swift中接受的答案。
斯威夫特2.3
override func viewDidLoad() {
//.....
let viewTapGestureRec = UITapGestureRecognizer(target: self, action: #selector(handleViewTap(_:)))
//this line is important
viewTapGestureRec.cancelsTouchesInView = false
self.view.addGestureRecognizer(viewTapGestureRec)
//.....
}
func handleViewTap(recognizer: UIGestureRecognizer) {
myTextField.resignFirstResponder()
}
