I have been able to successfully create push notifications and I have also received responses from the feedback service, so I am confident that my configuration is correct, but I was wondering, how long after a device has been made inactive, will it be picked up by the Apple Push Notification Service.

I'm automating a copy command to place some text on the pasteboard every second or so - unfortunately this is my only way of accessing the text, which is in another application. After copying, I access the pasteboard text and process it. Sometimes, the copy command will be sent when nothing is selected - for example in textEdit, if the...

On the final view, there is a button to add a photo, which presents a UIImagePickerController. So far, so good - however when I finish picking the image, or cancel the operation, the previous view is loaded, but without the tab ...

Is there an API for checking at runtime whether you are running on an iPhone or an iPad? One way I can think of would be to use: [[UIDevice currentDevice] model]; And detect the existence of the string @"iPad" - which seems a bit fragile. In the 3.2 SDK, I see that UIDevice also has a property which is really what I'm looking for, b...
