激活SearchBar

Question

我希望在客户选择标签栏上的搜索菜单时激活搜索栏并显示键盘。但是resignfirstresponder不起作用。你有其他建议吗？谢谢你的批准。 这是我的viewdidload方法

[[UITextField appearanceWhenContainedInInstancesOfClasses:@[[UISearchBar class]]] setTextColor:[UIColor grayColor]];
[[UITextField appearanceWhenContainedInInstancesOfClasses:@[[UISearchBar class]]] setBackgroundColor:[UIColor whiteColor]];
_searchBarNew.placeholder = [MCLocalization stringForKey:@"courses"];
_searchBarNew.backgroundImage = [UIImage imageNamed:@"grey_background"];
_searchBarNew.delegate = self;

Answer 1

UITapGestureRecognizer *tap = [[UITapGestureRecognizer alloc] 
                                   initWithTarget:self
                                   action:@selector(dismissKeyboard)];

[self.view addGestureRecognizer:tap];


Once your requirement is done , tap anywhere in the screen to resign                      the keyboard

-(void)dismissKeyboard {
   [TxtFieldObj resignFirstResponder];
}
