通过给视图添加手势实现收起键盘

- (void)viewDidLoad  

{  

    [super viewDidLoad];  

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

    tapGr.cancelsTouchesInView = NO;  

    [self.view addGestureRecognizer:tapGr];  

}  

-(void)viewTapped:(UITapGestureRecognizer*)tapGr{  

    [activitySearchBar resignFirstResponder];  

}
