How to initialize a UITextView programmatically? - iphone

Question

How can I initialize a UITextView that is nice and pretty. I have the line:
textView = [[UITextView alloc] initWithFrame:CGRectMake(150, 150, 100, 100)];
but I'd like to make it look nice and I do not know the functions or the syntax to do so. I'd like it to have word wraping and I'd like the corners to be rounded. Also, how can I make it so that the keyboard goes away if the user presses "Return" on the keyboard. And I'd like to make it say "Done" instead of "Return"

Answer 1

You should check the documentation. This is all in there. Specifically:
you can't set the border, you can only do that for a UITextField
you'll need to set your delegate and implement -textViewDidChange: to check for returns
you can set textView.returnKeyType to UIReturnKeyDone to get the Done button.
You might want to consider using a UITextField, as that object's delegate has a very convenient -textFieldShouldReturn: method, and you can, as I said, set its border.

Answer 2

check out the UItextInputTraits protocol that is linked from the UITextView documentation.
All of these properties can be found there, and others.
EX:
textView.returnKeyType = UIReturnKeyTypeDone;

To make the border look close to a UITextField, you can add the following lines.
[textView.layer setBorderColor:[[[UIColor grayColor] colorWithAlphaComponent:0.5] CGColor]];
[textView.layer setBorderWidth:1.0];
textView.layer.cornerRadius = 3;
textView.clipsToBounds = YES;
To release the keyboard by pressing 'Done'('Return') button, you can override the following protocol (UITextViewDelegate) method.
- (BOOL)textView:(UITextView *)textView shouldChangeTextInRange:(NSRange)range replacementText:(NSString *)text
{
if ([text isEqualToString:#"\n"]) {
[textView resignFirstResponder];
return NO;
}
return YES;
}
