iProgrammer Tip #5: Dismiss keyboard while entering text in UITextView..

We have managed to Dismiss keyboard from UITextField in response to ‘return’ in keyboard .

But unfortunately, the same trick wont be useful when working with UITextView.

UITextViewDelegate does not have such a method to be delegated. Below is the list of optional methods for UITextViewDelegate

@protocol UITextViewDelegate <NSObject>

@optional

- (BOOL)textViewShouldBeginEditing:(UITextView *)textView;

- (BOOL)textViewShouldEndEditing:(UITextView *)textView;

- (void)textViewDidBeginEditing:(UITextView *)textView;

- (void)textViewDidEndEditing:(UITextView *)textView;

- (BOOL)textView:(UITextView *)textView shouldChangeTextInRange:(NSRange)range replacementText:(NSString *)text;

- (void)textViewDidChange:(UITextView *)textView;

- (void)textViewDidChangeSelection:(UITextView *)textView;

@end

After staring at them for a while, it dawned that shouldChangeTextInRange could be our rescue.

- (BOOL)textView:(UITextView *)textView shouldChangeTextInRange:(NSRange)range replacementText:(NSString *)text

{

if([text isEqualToString:@"\n"])

{

[textView resignFirstResponder];

return FALSE;

}

return TRUE;

}
