Hi, I am using a TTStyledTextLabel in my project to parse the hyperlinks, it all works fine. The only problem I am facing is to truncate a long text - show ellipses if the text does not fit in the bounds of TTStyledTextLabel.

Hi, recently I joined two Xcode projects together. To get this thing to work, I had to alloc and initialize my view controller. self.myViewController = [[MyViewController alloc] init]; But why? In the other project I have the same code. The sole difference is hierarchy of the different views. I added a new view to the top (beginning)...

But the assignment of the class to my property also increased the retain count to 2. self.myProperty = [[MyClass alloc] init] Vs. MyClass *myCreatedVariable = [[MyClass alloc] init]; self.myProperty = myCreatedVariable ...
