iOS收起键盘手势

如果您在阅读我的文章时有疑问 , 请点击这里
在viewDidload里写一个手势

UITapGestureRecognizer *tap1 = [[UITapGestureRecognizer alloc] initWithTarget:self action:@selector(viewTapped:)];
    tap1.cancelsTouchesInView = NO;
    [self.view addGestureRecognizer:tap1];

实现方法

-(void)viewTapped:(UITapGestureRecognizer*)tap1{
    [self.view endEditing:YES];
}
