iphone autorotation动画

Question

是否可以关闭自动旋转的动画？我想让它旋转,但我只是不想要动画发生(就像一个即时开关).

Answer 1

如果你真的需要,只是使用setAnimationsEnabled的UIView:

- (void)willRotateToInterfaceOrientation:(UIInterfaceOrientation)toInterfaceOrientation duration:(NSTimeInterval)duration
{
    [UIView setAnimationsEnabled:NO]; // disable animations temporarily
}

- (void)didRotateFromInterfaceOrientation:(UIInterfaceOrientation)fromInterfaceOrientation
{
    [UIView setAnimationsEnabled:YES]; // rotation finished, re-enable them
}

这对我有用.当然,除非你有充分的理由这样做,否则不建议这样做.
