System Fonts delay / UIButton

TTStu

Hi,

I am mixing some UIButtons and SPTextField stuff in the init method of an SPSprite.

The SPTextField is simply using Arial system font (instead of bitmap fonts).

I know there is a known performace hit when asking SPTextField to use system fonts, however I am getting a good half a second to 1 second delay between the UIButtons appearing and then ANY of the sparrow screen appearing around it.

So the UIButtons appear "over" the previous view, then Sparrow "catches up" and renders the rest of the view (imagery + the SPTextFields mentioned) around it after a delay.

Any ideas/suggestions?

It's not a show stopper, and I could always introduce artificial delays to the UIButtons appearing, but it just doesn't feel... nice lol

I have never had such a large delay when initializing SPTextFields.

Are the texts of the SPTextFields really long?
Have you tried commenting out various initializations of objects in the SPSprite to figure out if the delay really is caused by SPTextField, or changing the font of the SPTextField to a bitmap font to see if the delay is hugely minimized?
Have you tested on the device, as well as the simulator?
I havent used the Time Profiler instrument much, but that might help you pin-point the problem, I also suggest to call NSLog() before and after every initialization of objects to figure out where the delay is, if you still haven't figured it out.

If you like, you may PM me the project or a sample of the issue and I will have a look when I have time.

Hi, I just stripped down the offending class you can pasted into Scaffold and hopefully you will see what I mean, the UIButton appears before any other Sparrow rendering takes place (happens using Sparrow 2.01 on iOS 7 on iPhone 5 and iPad 4 and iOS 5 iPad 1).
