I want to mytextview delegate was called before call UIKeyboardWillShowNotification

How to I can resolve this problem

Answer 1

Use textViewShouldBeginEditing provided by the UITextViewDelegate, call your delegate method in it, and return YES from this method to let user edit the text.

- (BOOL)textViewShouldBeginEditing:(UITextView *)textView
{
    [yourDelegate yourMethod:textView];
    return YES;
}

Answer 2

The sequence of Event execution are

1. UIKeyboardWillShowNotification
2. textViewDidBeginEditing

Now as per our requirement I Fire On Notification that is called when KeyBoardWillShow.

[[NSNotificationCenter defaultCenter] addObserver:self selector:@selector(textViewDidBeginEditing:)name:UIKeyboardWillShowNotification object:nil]

And in the selector I passed same function which is called after UIKeyBoardWillShown, Also you can set your Own Function, which you want to do Before UIKeyBoardShow

This is My Code

- (void)viewDidLoad {
        [super viewDidLoad];
        [[NSNotificationCenter defaultCenter] addObserver:self selector:@selector(textViewDidBeginEditing:) name:UIKeyboardWillShowNotification object:nil];

    }

    - (void)textViewDidBeginEditing:(UITextView *)textView {
        NSLog(@"textViewDidBeginEditing");
    }
