问题描述

我想将图像延迟 360 度旋转 2 或 3 秒，再次将其旋转 360 度，该过程应继续进行.有什么可能的建议吗?实际上尝试过 Cgaffinetransfom 但它不适用于 360 度.

I want to rotate an image by 360 degree delay for 2 or 3 seconds again rotate it by 360 degree and the process should continue on. Any possible suggestions for the same ? Actually tried Cgaffinetransfom but its not working for 360 degree .

推荐答案

您可以像这样旋转图像:

You can rotate your image like this:

[YourImageView setTransform:CGAffineTransformMakeRotation(10*(M_PI/360))];

现在要连续执行它，您需要像这样设置计时器:

Now to perform it continuous you need to set the timer like this:

[NSTimer scheduledTimerWithTimeInterval:3.0 target:self selector:@selector(doRotateImage) userInfo:nil repeats:YES];

旋转功能:

-(void)doRotateImage{
    [YourImageView setTransform:CGAffineTransformMakeRotation(10*(M_PI/360))];
}

就是这样.
