The status bar is actually in its own UIWindow, in your code you are only rendering the view of your viewcontroller which does not include this.

The "official" screenshot method was here but now seems to have been removed by Apple, probably due to it being obsolete.

Under iOS 7 there is now a new method on UIScreen for getting a view holding the contents of the entire screen:

- (UIView *)snapshotViewAfterScreenUpdates:(BOOL)afterUpdates

This will give you a view which you can then manipulate on screen for various visual effects.

If you want to draw the view hierarchy into a context, you need to iterate through the windows of the application ([[UIApplication sharedApplication] windows]) and call this method on each one:

- (BOOL)drawViewHierarchyInRect:(CGRect)rect afterScreenUpdates:(BOOL)afterUpdates

You may be able to combine the two above approaches and take the snapshot view, then use the above method on the snapshot to draw it.
