iOS - UIToolBar as inputAccessoryView for UITextView

Question

I've added a UIToolBar with a UIBarButtonItem as inputAccessoryView for a UITextView. It works fine but the UIBarButtonItem is touchable outside it's frame, perhaps 50 pixels outside to the right. It's no big deal but it annoys me. Anyone know why?

This is my code (ARC):

UIToolbar *toolBar = [[UIToolbar alloc] initWithFrame:CGRectMake(0, self.view.bounds.size.height, 320, 44)];
toolBar.barStyle = UIBarStyleBlack;
toolBar.translucent = YES;

UIBarButtonItem *doneButton = [[UIBarButtonItem alloc] initWithBarButtonSystemItem:UIBarButtonSystemItemDone target:self action:@selector(doneWriting:)];
[toolBar setItems:[NSArray arrayWithObjects:doneButton, nil]];

self.messageTextView.inputAccessoryView = toolBar;

Answer 1

In iOS 6 it seems to behave as expected. Nice tip: If you want the button to appear on the right instead of the left, use one of these:

UIBarButtonItem *flexibleSpace = [[UIBarButtonItem alloc] initWithBarButtonSystemItem:UIBarButtonSystemItemFlexibleSpace target:self action:nil];

Then initialise the toolbar with:

[toolBar setItems:[NSArray arrayWithObjects:flexibleSpace, doneButton, nil]];
