Following is the scenario where I found in iOS 4.3 simulator :
Create a DTAttributeTextView with string "welcome".
Now , on click of any button I tried to erase the string completely. Say Now I call setAttributedString for a string "".
It won;t getting updated in the iOS 4.3, but updated on iOS 5.0, iOS 5.1 Simulator.
Please let me know, if more info required or if any work around available for this.
@mobidever do you still have the problem, or have you ditched 4.3?
An additional setNeedsDisplay on the content view might be needed.
