横向模式下的shouldAutorotateToInterfaceOrientation UIToolbar将关闭1个像素

Question

I do add a Toolbar to my view like this:

self.myToolbar = [UIToolbar new];
    self.myToolbar.barStyle = UIBarStyleDefault;
    self.myToolbar.tintColor = [UIColor BAR_COLOR];
    self.myToolbar.frame = CGRectMake(0, self.view.bounds.size.height-44, 320, 44);
    self.myToolbar.autoresizingMask = (UIViewAutoresizingFlexibleLeftMargin|UIViewAutoresizingFlexibleTopMargin|UIViewAutoresizingFlexibleWidth|UIViewAutoresizingFlexibleHeight);
[self.view addSubview:myToolbar];

In the interface builder I set fixed to top and left margin for the view. Also in the simulated metrics I set Status Bar to Black, Top Bar to Navigation Bar and Bottom Bar to None.

This works perfect in portrait mode. And looks like this:

Now when I rotate to landscapemode the toolbar gets resized and everything BUT it is off the buttom by one pixel like this:

What could be the cause off this?

Answer 1

The following code is working :

self.myToolbar = [UIToolbar new];
self.myToolbar.barStyle = UIBarStyleDefault;
self.myToolbar.tintColor = [UIColor BAR_COLOR];
CGRect screenRect = [[UIScreen mainScreen] applicationFrame]; //get the rect of the screen 
self.myToolbar.frame = CGRectMake(screenRect.origin.x, screenRect.size.height-44, screenRect.size.width, 44);
self.myToolbar.autoresizingMask = UIViewAutoresizingFlexibleLeftMargin | UIViewAutoresizingFlexibleTopMargin | UIViewAutoresizingFlexibleWidth | UIViewAutoresizingFlexibleHeight;
[self.view addSubview:myToolbar];

EDIT

It is actually a bug occuring on the iOS5 simulator.
