UITextField auto correction crash in iOS 4.3 on simulator

Question

The UITextField's auto correction crashes my app on the simulator with iOS 4.3 sdk build target. Works fine on the device and in the simulator with iOS 4.2 sdk.

Anyone else experiencing this issue? I'm figuring its a bug with the 4.3 sdk?

As soon as I type the second character. Stack Trace

Also at times, you will see a much simpler trace that simply starts at main, then ceases immediately on objc_assign_ivar. This happens also when typing in a text field, such as a UISearchBar.

Answer 1

On the simulator, open Settings -> Keyboard and turn OFF all the options. This prevents the crash (until the bug is addressed).

Answer 2

I am experiencing the same issue, running the 4.3 simulator on Lion Developer Preview 2. This is a bug in the simulator on Lion. I have been temporarily disabling autocorrection (setAutocorrectionType: UITextAutocorrectionTypeNo).

Answer 3

We have to update Simulator 4.3 by following these steps:

1. Go to Xcode -> Preferences -> Download
2. Update iOS 4.3 Simulator

And Reset Simulator and run it again. It's done.

Answer 4

Please file a bug report at http://bugreport.apple.com if you feel that there is a bug in the SDK.

But, to answer you, I am not experiencing the same issue, so it might be a problem in your code. Could you check the stack trace before the crash and see if there's something you're missing that somehow worked in older OS versions?
