iOS回收键盘

1.回收某个textField下弹出的键盘

1 - (BOOL)textFieldShouldReturn:(UITextField *)textField{
2
3     [textField resignFirstResponder];
4     return YES;
5
6 }

2.点击空白处回收键盘

 1 -(void)touchesBegan:(NSSet<UITouch *> *)touches withEvent:(UIEvent *)event
 2
 3 {
 4
 5     [self.phoneNumTF resignFirstResponder];
 6
 7     [self.secretTF resignFirstResponder];
 8
 9
10 }

3.点击空白处回收键盘（添加手势）

 1 - (void)viewDidLoad
 2 {
 3     [super viewDidLoad];
 4     UITapGestureRecognizer *tapGestureRecognizer = [[UITapGestureRecognizer alloc] initWithTarget:self action:@selector(keyboardHide:)];
 5     //设置成NO表示当前控件响应后会传播到其他控件上，默认为YES。
 6     tapGestureRecognizer.cancelsTouchesInView = NO;
 7     //将触摸事件添加到当前view
 8     [self.view addGestureRecognizer:tapGestureRecognizer];
 9 }
10
11 -(void)keyboardHide:(UITapGestureRecognizer*)tap{
12     [textFiled resignFirstResponder];
13 }
