Where is NSAlert.h in the iOS SDK?

Question

According to iOS\'s Using and Creating Error Objects, one can display a error object with the following code.

NSError *theError = nil;
BOOL success = [myDoc          


        

Answer 1

NSAlert isn't availble in UIKit. the example it just an copy past of the OS X doc.

This code in Listing 2-1 uses the returned NSError to display an error alert to the user immediately. (UIAlertView, the UIKit class corresponding to NSAlert, has no equivalent method for alertWithError:.) Error objects in the Cocoa domain are always localized and ready to present to users, so they can often be presented without further evaluation.
