Hi Everybody! I have a simple piece of code that works on every system except iOS4. It's about resigning first responder for a UITextField. The text field is all wired up, and here's the code for the delegate: - (BOOL)textFieldShouldReturn:(UITextField *)textField{ [opis resignFirstResponder]; return YES; } I've tried it almo...
Is there a way (with iOS4) when the user hits the home button (in order to exit an application) to convey to the iOS4 system to not keep the app running in the background but to remove the app completely from memory (like iPhone 3)? My app could potentially display sensitive information and I'd like for it to exit completely. Thanks ...

Have I messed up some settings or is there some work-arounds to make UIToolbar and UISearchBar use more similar coloring? These are overlapping in real...
Is there an alternative or new stuff in iOS4 that resembles TTPickerTextField I am looking for a way to recreate the "new mail" control view and I've read about TTPickerTextField. Three20 is my last option (especially as it has no iPad version) and I wanted to know if iOS4 gives some new UI controls to do this. ...
I know that the only way to turn on the flash and keep it on on iPhone 4 is by turning the video camera on. I'm not too sure of the code though.

I have iPhone 3GS, iOS4, xcode 3.2.3. After loading the Default.png, I add a little splash screen the looks exactly like the application start view.

The latest Xcode IDE requires you to target iPhone SDK 4 while dynamically handling deprecated and new functionality if you set the application to deploy to earlier releases. So can I use new features like Blocks and still have it work on a device running iPhone OS 3.0 or 3.1 or 3.1.3? I have not found documentation on how to do backwa...
