ios - Swift - UIProgressView 对角填充

Question

所以我设置了一个 UIProgressView 在 3 秒后填充，并稍微增加了条的高度。但是，当它填满时，它会沿对角线填充，而不是仅从一侧填充到另一侧。该栏从右上角开始，然后在结束之前扩展以填充进度视图。

这是我正在使用的代码：

import UIKit

class LoadingScreen: UIViewController {


    @IBOutlet weak var progressView: UIProgressView!


    override func viewDidLoad() {
        super.viewDidLoad()

        UIView.animateWithDuration(3, animations: { () -> Void in
            self.progressView.setProgress(1.0, animated: true)
        })

        progressView.transform = CGAffineTransformScale(progressView.transform, 1, 10)

}


}

以下是一些截图：

来晚了，但我刚刚经历了这一点，并通过将我的 progressView 样式更改为 .Bar 来修复它。希望有帮助！

let progressView = UIProgressView(progressViewStyle: .Bar)

Answer 2

It seems that the size of the progressView is incorrect.

Try to put these code in viewDidLayoutSubviews:

override func viewDidLayoutSubviews() {
    super.viewDidLayoutSubviews()

    UIView.animateWithDuration(3, animations: { () -> Void in
        self.progressView.setProgress(1.0, animated: true)
    })

    progressView.transform = CGAffineTransformScale(progressView.transform, 1, 10)
}
