在viewDidLoad中添加手势

- (void)viewDidLoad{ 

[super viewDidLoad]; 

//添加手势

UITapGestureRecognizer *tap1 = [[UITapGestureRecognizer alloc] initWithTarget:self action:@selector(viewTapped:)]; 

tap1.cancelsTouchesInView = NO; 

[self.view addGestureRecognizer:tap1]; 

}

然后 实现方法即可

-(void)viewTapped:(UITapGestureRecognizer*)tap1

{ 

[self.view endEditing:YES];

}
