ios - 进度的宽度和高度查看

Question

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

它不能一起工作。
或progressView旋转90或更改大小

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

Answer 1

您需要链接转换。在您的示例中，transform的第二个分配有效地覆盖了第一个。这个作品:

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];
