问题 I added a UIProgressView to my UIActionSheet to indicate the download progress. So I do not want my UIActionSheet to be dismissed when user click the download button in it.

But since the progress bar fill color and background color are dramatically different (navy blue progress fill and white background/non filled area), I'm wondering how to dynamically

问题 I'm performing a request to get an image asset given a PHAsset , and I'm using UIProgressView to indicate the progress using the progressHandler PHImageRequestOptions allows me to provide. When that handler is called, it provides me with progress so I set the progress on the progress view but I also animate to that new progress via setProgress:animated: . I now need to figure out how to hide the progress view once progress has reached 1.0, but not until it has finished animating to 1.0. For

问题 I have subclassed UIProgressView as: import UIKit class MyProgressView: UIProgressView { override func sizeThatFits(size: CGSize) -> CGSize { return CGSizeMake(size.width, 6) } } and I am using it as: let progress = MyProgressView() progress.progress = 0.33 progress.layer.cornerRadius = 0 progress.tintColor = .white progress.trackTintColor = UIColor.white.colorWithAlphaComponent(0.4) navigationItem.titleView = progress it's working fine, but it has rounded corners like below I want it to be

问题 I'm using a UIProgressView and want to stick a image subview to the progress % as in the image below: I want to get the co-ordinate of the progress tint and red subview as in the figure to " stick " with the progress tint, whatever the progress will be.. 回答1: You can start by vertically centering the image view with the progress view using constraints or programmatically like below. imageView.center.y = progressView.center.y Then where ever you are updating the progress, after you can
