iPad - CGAffineTransformMakeRotation - 保持旋转

发布于 2024-10-21 15:19:45 字数 1026 浏览 6 评论 0原文

我有一个平视显示器（HUD），我试图让它随着视图正确旋转。我创建了一个函数orientationWillChange，它应该旋转视图并且工作正常，只需要在实现它的视图控制器方面进行更多编程。

我的主要问题是它关闭时会旋转。当它关闭时，它会进行一些其他转换（缩小/褪色，使其消失），但它似乎将其旋转回“正常”。

我不想将视图再旋转 90 度，我只想确保它保持当前的旋转状态。我该怎么做？

我的关闭函数如下：（

- (void)close {
    _windowIsShowing = NO;
    [UIView animateWithDuration:0.125 animations:^{
        hudView.transform = CGAffineTransformMakeRotation(rotationDegrees * M_PI / 180);
        hudView.transform = CGAffineTransformMakeScale(1.1, 1.1);
    } completion:^(BOOL finished) {
        [UIView animateWithDuration:0.15 animations:^{
            hudView.transform = CGAffineTransformMakeScale(0.4, 0.4);
            hudView.alpha = 0.0;
            backgroundColorView.alpha = 0.0;
        } completion:^(BOOL finished) {
            [hudWindow resignKeyWindow];
            [self release];
        }];
    }];
}

仅供参考，这是基于 CloudApp 的 HUD )

I have a heads up display (HUD) that I'm trying to get to properly rotate with the view. I created a function orientationWillChange that is supposed to rotate the view and that works fine, just requires a little more programming on the side of the view controller implementing it.

My main problem is that it rotates when it closes. It does some other transformations when it closes (shrinking/fading it so it disappears), but it seems to be rotating it back to "normal".

I don't want to rotate the view another 90 degrees, I just want to make sure it stays in the rotation it is at. How do I do that?

My closing function is as follows:

- (void)close {
    _windowIsShowing = NO;
    [UIView animateWithDuration:0.125 animations:^{
        hudView.transform = CGAffineTransformMakeRotation(rotationDegrees * M_PI / 180);
        hudView.transform = CGAffineTransformMakeScale(1.1, 1.1);
    } completion:^(BOOL finished) {
        [UIView animateWithDuration:0.15 animations:^{
            hudView.transform = CGAffineTransformMakeScale(0.4, 0.4);
            hudView.alpha = 0.0;
            backgroundColorView.alpha = 0.0;
        } completion:^(BOOL finished) {
            [hudWindow resignKeyWindow];
            [self release];
        }];
    }];
}

(fyi this is based on CloudApp's HUD)
