becomeFirstResponder not working in iOS 8

I am using UITextField's method becomeFirstResponder to show the keyboard.
This is working in iOS 7. But in iOS 8 this method doesn't show the keyboard.

UITextField *txtAddNew = [[UITextField alloc] initWithFrame:CGRectMake(10,10,240, 21)];
txtAddNew.font = [UIFont fontWithName:@"Helvetica" size:16];
txtAddNew.clearButtonMode = UITextFieldViewModeWhileEditing;
txtAddNew.returnKeyType = UIReturnKeyDone;
txtAddNew.delegate = self;
txtAddNew.autocorrectionType = UITextAutocorrectionTypeNo;
txtAddNew.tag = 15;

// Open keyboard
[txtAddNew becomeFirstResponder];

Is there any way to do it in iOS 8?

Answer Source

Try calling becomeFirstResponder like below

[txtAddNew performSelector:@selector(becomeFirstResponder) withObject:nil afterDelay:0];

As per Apple,

A responder object only becomes the first responder if the current responder can resign first-responder status (canResignFirstResponder) and the new responder can become first responder.

You may call this method to make a responder object such as a view the first responder. However, you should only call it on that view if it is part of a view hierarchy. If the view’s window property holds a UIWindow object, it has been installed in a view hierarchy; if it returns nil, the view is detached from any hierarchy.
