progressView的宽高

Question

如何创建宽度为 100、高度为 200 的 progressView。并将 progressView 旋转 90 度？

不能一起使用。或progressView转90或改变尺寸

self.progressView.transform = CGAffineTransformMakeRotation(M_PI_2);
    CGAffineTransform transform = CGAffineTransformMakeScale(1.0f, 3.0f);
    _progressView.transform = transform;

Answer 1

我在某处读到过...我认为 CGAffineTransform() 适合

[self.progressView setTransform:CGAffineTransformMakeScale(1.0, 2.0)];

轮换

#define DEGREES_TO_RADIANS(angle) ((90) / 180.0 * M_PI)
[self.progressView setTransform:CGAffineTransformMakeRotation(DEGREES_TO_RADIANS(angle))];

Answer 2

您需要链接您的转换。在您的示例中，对 transform 的第二次分配有效地覆盖了第一次分配。这个有效：

UIProgressView *progressBar = [[UIProgressView alloc] initWithProgressViewStyle:UIProgressViewStyleBar];
progressBar.frame = CGRectMake(50, 100, 100, 50);
CGAffineTransform t = CGAffineTransformMakeRotation(M_PI_2);
t = CGAffineTransformScale(t, 1.0f, 50.0f);
progressBar.transform = t;
[self.view addSubview:progressBar];

Answer 3

Swift 4

progressView.transform = CGAffineTransform(scaleX: 1.0, y: 2.0)
