问题 I was solving my app's memory leak problem, I narrowed the scope, and found out the "leak" (instruments didn't say leak, but memory went up) came from this method: - (void)loadDataSource { self.enLabel.text = self.dataSource.en; // English words self.cnLabel.text = self.dataSource.cn; // Chinese translation } The app is a flash cards app. Swipe to switch to next card. Tap to see answer(cnLabel.hidden = NO). It has only 2 CardView, when prepareing next card, cardView.dataSource will be set,

问题 I just came across a very strange problem in a custom UILabel subclass and I need some help to figure out what is going on. The question appears to be pretty long, but this is mostly due to the images I have added to illustrate the problem as good as possible :-) Thank you very much for your help! The MyHTMLLabel class uses the awakeFromNib() method to parse its text property for HTML like <hightlight> tags to show the text between these tags in a a different color. This has worked without

问题 I'm using an NSNumberFormatter to display a percentage: NSNumberFormatter *inclineFormat = [[[NSNumberFormatter alloc] init] autorelease]; [inclineFormat setMinimumFractionDigits:1]; [inclineFormat setNumberStyle:NSNumberFormatterPercentStyle]; It's working as expected with the exception that the design team would like to see the "%" in superscript. Is there anyway to specify that using NSNumberFormatter? I'm displaying the formatted string in a UILabel in iOS devices. 回答1: % does not exist

问题 My app freezes when it reaches this part of the code. I am attempting to increment a number with a half of a second delay, then printing that to the screen. So the label text would turn into a 1, then a 2, then a 3, etc. I threw this code into playground and the DispatchQueue seems to infinitely go up. Thanks. var percentage = 0 func incrementLabel (amount: Int){ var count = 0 while count <= amount{ DispatchQueue.main.asyncAfter(deadline: .now() + 0.5, execute: { percentage += 1 count += 1 })

问题 I am trying to retain the objects from the console to be shown in as a label(classifierText). The warning of "UILabel.text must be used from main thread only" appears. What seems to the problem as to why the items are being shown as the label? var previewLayer: AVCaptureVideoPreviewLayer! let classifierText: UILabel = { let classifier = UILabel() classifier.translatesAutoresizingMaskIntoConstraints = false classifier.textColor = .black classifier.font = UIFont(name: "Times-New-Roman", size:

问题 I want to style a text using NSAttributedString . The text should have a background and a custom padding, so that the text has a little bit of space to the background's edge. This is what I want to achieve: This is what I don't want to achieve (background in the second line is not word / character-specific): And this is the code that I tried in a playground: let quote = "some text with a lot of other text and \nsome other text." let paragraphStyle = NSMutableParagraphStyle() paragraphStyle

问题 Problem centerLabelGesture is being defined outside of the scope of viewDidLoad() , so at the time that .addGestureRecognizer(centerLabelGesture) is called, centerLabelGesture is not defined yet. import UIKit import SnapKit class ViewController: UIViewController { var screen: UIView! var centerLabel: UILabel! override func viewDidLoad() { super.viewDidLoad() screen = UIView() centerLabel = UILabel() view.addSubview(screen) screen.addSubview(centerLabel) screen.backgroundColor = .white screen

问题 How to add a space before and after the text in UILabel using storyboard. Here is an example of label with a background. 回答1: One approach is: Use auto layout in the storyboard. Use a UILabel subclass that overrides intrinsicContentSize to be a little wider than the default. For example: extension CGSize { func sizeByDelta(dw dw:CGFloat, dh:CGFloat) -> CGSize { return CGSizeMake(self.width + dw, self.height + dh) } } class MyWiderLabel : UILabel { override func intrinsicContentSize() ->
