UIToolbar Bug iOS8 Beta 5 AND GM - UPDATE: Fix included!

CodeForUIToolbarBugiOS8Beta5.m

// Execute the following code somewhere in your app

UIToolbar *datePickerToolbar = [[UIToolbar alloc] initWithFrame:CGRectMake(0.f, 50.f, self.window.bounds.size.width, 44.f)];

UIBarButtonItem *flexibleSpace = [[UIBarButtonItem alloc] initWithBarButtonSystemItem:UIBarButtonSystemItemFlexibleSpace target:nil action:nil];
UIBarButtonItem *cancelButton = [[UIBarButtonItem alloc] initWithTitle:@"Cancel" style:UIBarButtonItemStylePlain target:self action:nil];
UIBarButtonItem *doneButton = [[UIBarButtonItem alloc] initWithTitle:@"OK" style:UIBarButtonItemStyleDone target:self action:nil];

datePickerToolbar.items = @[cancelButton, flexibleSpace, doneButton];
 
[self.window addSubview:datePickerToolbar];

/*
 * On iOS 8 Beta 5 and Golden Master the buttons will have no horizontal margin to 
 * the UIToolbar's frame when added to an UIWindow.
 * When added to an UIView there is the typical frame.
 *
 * On iOS 8 Beta 1 the buttons have the typical margins also when added to an UIWindow.
 *
 * If you look at the images you will see what I mean.

 /*
  * UPDATE on 10.09.2014:
  * =====================
  * Fix which needs to check against name of private API class but it's obfuscated
  * as much as possible.
  * You need to override UIToolbar as follows:

Just ran across this in a Google search, but in general, adding views directly to the UIWindow is not a good idea -- you would normally want to add as a subview of window.rootViewController.view .
