UINavigationBar drawRect Alternative (aka, Need CoreGraphics calls in a category)

I recently discovered that in > iOS5 UINavigationBar does not get its drawRect called. I want to figure out how to draw with Core Graphics in a category.

The end goal I am trying to achieve is eliminating images from my app and have everything drawn at runtime. I am also trying to make this library automatic, so that users don't have to think about using my custom classes.

Is there a way to replace a class with one of your own at runtime? like: replaceClass([UINavigationBar class], [MyCustomBar class]);

Thanks in advance.

Solution

  • I found the solution, Instead of messing with draw rect, I just made some methods that draw to a UIImage then set the image as the background view for the elements i am customizing. It makes my custom UI magic again.
