Answer 1

If u want that ur keyboard is resigned when click on return then u have to write, implement this method....
- (BOOL)textView:(UITextView *)textView shouldChangeTextInRange:(NSRange)range replacementText:(NSString *)text {
if([text isEqualToString:#"\n"]) {
[textView resignFirstResponder];
return NO;
}
return YES;
}
Just make it copy and paste....:)

Answer 2

Make sure you declare support for the UITextViewDelegate protocol.
- (BOOL)textView:(UITextView *)textView shouldChangeTextInRange:(NSRange)range replacementText:(NSString *)text {
if([text isEqualToString:#"\n"]) {
[textView resignFirstResponder];
return NO;
}
return YES;
}

Answer 3

You should use the UITextViewDelegate. You have to declare the use of the protocol in your class header like:
#interface YourClass:NSObject<UITextViewDelegate>
Then in your .m, you should set your class as delegate in some point with something like:
textView.delegate = self;
Then, in your .m again, you have to implement the delegate methods, in particular:
textViewDidChange:
You can read the protocol reference at http://developer.apple.com/library/ios/#documentation/uikit/reference/UITextViewDelegate_Protocol/Reference/UITextViewDelegate.html for more information.

Answer 4

There is no specific delegate method for UITextview to know when user hits "RETURN"
So you can do like this
//In .h File
#interface BlahBlah : UIViewController <UITextViewDelegate>
#property(nonatomic, retain) IBOutlet UITextView *myTextView;
#end
//In .m File
#implementation BlahBlah
#synthesis myTextView;
//In some method, can be viewDidLoad OR viewDidAppear . your convenience ;)
{
self.myTextView.delegate = self;
}
- (BOOL)textView:(UITextView *)textView shouldChangeTextInRange:(NSRange)range replacementText:(NSString *)text {
if([text isEqualToString:#"\n"]) {
[textView resignFirstResponder];
return NO;
}
return YES;
}
