IOS-当触摸UITextField外部时关闭键盘

Question

IOS-当触摸UITextField外部时关闭键盘我想知道当用户触摸到UITextField.

Answer 1

您需要添加一个UITapGestureRecogniser并将其分配到视图中，然后在UITextField上面是选择器。

守则：

视图DidLoad

UITapGestureRecognizer *tap = [[UITapGestureRecognizer alloc] initWithTarget:self action:@selector(dismissKeyboard)];[self.view addGestureRecognizer:tap];

解雇键盘：

-(void)dismissKeyboard 
{
    [aTextField resignFirstResponder];}

(在哪里aTextField是负责键盘的文本字段)

SWIFT 3版本看起来是这样的

let tapGesture = UITapGestureRecognizer(target: self, action: #selector(self.dismissKeyboard (_:)))self.view.addGestureRecognizer(tapGesture)

解雇键盘

func dismissKeyboard (_ sender: UITapGestureRecognizer) {
    aTextField.resignFirstResponder()}

Answer 2

我想出了几个答案。

使用在viewDidLoad:

UIGestureRecognizer *tapper;- (void)viewDidLoad{
    [super viewDidLoad];
    tapper = [[UITapGestureRecognizer alloc]
                initWithTarget:self action:@selector(handleSingleTap:)];
    tapper.cancelsTouchesInView = NO;
    [self.view addGestureRecognizer:tapper];}

删除当前正在编辑的内容：

- (void)handleSingleTap:(UITapGestureRecognizer *) sender{
    [self.view endEditing:YES];}
