三種關閉鍵盤的方法

第一種：手勢關閉：

- (void)viewDidLoad {

    [superviewDidLoad];

    // Do any additional setup after loading the view from its nib.

    UITapGestureRecognizer *tapGesture=[[UITapGestureRecognizeralloc] initWithTarget:selfaction:@selector(keyBoardHidden)];

    tapGesture.cancelsTouchesInView=NO;

   // tapGesture.numberOfTapsRequired=1;

    [self.viewaddGestureRecognizer:tapGesture];

}

-(void)keyBoardHidden{

    [_inputaccountresignFirstResponder];

    [_inputseceretresignFirstResponder];

}

第二種：-(void)touchesBegan:(NSSet *)touches withEvent:(UIEvent *)event

{  

   [textFiled resignFirstResponder]; 

}
