我怎样才能使图像总是面对？ [英] How can I make image always face up?

问题描述

我有一个描述猴子的头的图像。我想那猴子的头始终朝上。当您打开猴子的头转动过该设备，但我想的是，尽管iPhone的旋转猴子头dooesn't打开（如指南针）。

I have an image that describes a head of a monkey. I want that the head of the monkey always face up. When you turn the device the head of the monkey turns too, but I want that in spite of the rotation of the iphone the monkey head dooesn't turn (like a compass).

我怎样才能做到这一点？

How can I do this?

推荐答案

如果你想跟着设备，因为它变成你就必须跟踪与CLLocationManager。

If you want to follow the device as it turns you'll have to track with the CLLocationManager.

但如果你只是想猴子直立从纵向到横向（和它们的对立面）用户跃迁那么也许UIInterfaceOrientation将这样的伎俩：

But if you just want the monkey to be upright as the user transistions from portrait to landscape (and their opposites) then maybe the UIInterfaceOrientation will do the trick:

- (BOOL)shouldAutorotateToInterfaceOrientation:(UIInterfaceOrientation)interfaceOrientation 
{
    return YES;
}
