Hi,
In my app, I have a custom text view so I've implemented the UITextInput protocol to help me gather text from the keyboard.
I'm getting a strange memory leak when the method textInRange is called:
- (NSString *)textInRange:(UITextRange *)range
{
if (self.keyboardInputAccessoryMenuView)
{
IndexedRange *r = (IndexedRange *)range;
NSString *textString = self.labelView.labelTextView.text.string;
if ([self rangeExists: r.range inString:textString])
{
return ([textString substringWithRange:r.range]);
}
else
{
return nil;
}
}
else
{
return nil;
}
}
"text" is an NSMutableAttributedString. The error exists at the following line:
return ([textString substringWithRange:r.range]);
This is the crash log I'm getting:

This code in this function works most of the time, but occasionally I get this bug out of nowhere and can't recreate it.
Can anyone offer any insight on this?
