我想知道如何使键盘消失时,用户触摸以外的UITextField。
当前回答
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];
}
其他回答
override func touchesBegan(touches: Set<UITouch>, withEvent event: UIEvent?) {
if let touch = touches.first{
view.endEditing(true)
}
}
- (void)viewDidLoad
{
[super viewDidLoad];
UITapGestureRecognizer *singleTapGestureRecognizer = [[UITapGestureRecognizer alloc]
initWithTarget:self
action:@selector(handleSingleTap:)];
[singleTapGestureRecognizer setNumberOfTapsRequired:1];
[singleTapGestureRecognizer requireGestureRecognizerToFail:singleTapGestureRecognizer];
[self.view addGestureRecognizer:singleTapGestureRecognizer];
}
- (void)handleSingleTap:(UITapGestureRecognizer *)recognizer
{
[self.view endEditing:YES];
[textField resignFirstResponder];
[scrollView setContentOffset:CGPointMake(0, -40) animated:YES];
}
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; }
这个怎么样:我知道这是一个老帖子。它可能会帮助某些人:)
- (void)touchesEnded:(NSSet *)touches withEvent:(UIEvent *)event {
NSArray *subviews = [self.view subviews];
for (id objects in subviews) {
if ([objects isKindOfClass:[UITextField class]]) {
UITextField *theTextField = objects;
if ([objects isFirstResponder]) {
[theTextField resignFirstResponder];
}
}
}
}
你需要添加一个UITapGestureRecogniser并将其分配给视图,然后在它的选择器上的UITextField上调用resign first responder。
代码:
在viewDidLoad
UITapGestureRecognizer *tap = [[UITapGestureRecognizer alloc] initWithTarget:self action:@selector(dismissKeyboard)];
[self.view addGestureRecognizer:tap];
在dismissKeyboard:
-(void)dismissKeyboard
{
[aTextField resignFirstResponder];
}
(其中,aTextField是负责键盘的文本字段)
Swift 3版本是这样的
let tapGesture = UITapGestureRecognizer(target: self, action: #selector(self.dismissKeyboard (_:)))
self.view.addGestureRecognizer(tapGesture)
对于dismissKeyboard
@objc func dismissKeyboard (_ sender: UITapGestureRecognizer) {
aTextField.resignFirstResponder()
}
