问题 I am working on auto layout in my app.I have a functionality to increase the font size of entire app through slider movement.The issue is when i increase the font size the text of the label turns into ellipses. I have given the constraints to my label a fixed width and increasing variable height but this doesn't solve any problem. Do i need to give line break mode (word-wrap) and specify the number of lines for every text or there any other solution to this ? Any help will be appreciated. 回答1

问题 I've looked at a bunch of posts, but the advice given in these has not worked: UILabel not updating (changing order of loading view controller) UILabel Refresh (threading dependence) etc All I am doing is modally loading one view controller from another and before the modal load setting some properties of the view controller. Here's where I create and load the view controller: - (void)swipeUp:(UISwipeGestureRecognizer *) gr { RespondViewController *rvc = [[RespondViewController alloc] init];

问题 I have a weird issue: I have a UIScrollView whose background is transparent. Inside of it there are a few UILabels also with a transparent background and with a custom font. When the scrollview is first displayed everything looks sharp and good but as soon as I start panning the scroll view, the text of the labels gets extremely pixelated. This does not happen if i set an opaque background to the labels. Do you have any idea what might be causing this? 回答1: This sounds like you may be adding

问题 I am trying to create a custom UILabel class which will allow me to increase the line spacing on a UILabel. I know you can do this in IB with an attributed text string, however it doesn't work if you are using custom fonts. Here is my class code: import UIKit @IBDesignable class SpacingLabel: UILabel { @IBInspectable var lineSpacing: CGFloat = 10.0 override func awakeFromNib() { self.renderText() } override func prepareForInterfaceBuilder() { super.prepareForInterfaceBuilder() self.renderText

问题 I have something like : "Jossmaisel ♡" I want to show it in UILabel.But the special character shows up as two chars instead of the heart sign. Is it something related to the encoding? Somehow I need to do something about UTF 8 ? Can anyone kindly help me out ? 回答1: Have you escaped the heart character? As in @"Jossmaisel \u2661" ? In UTF-8 encoding, it would take three bytes. 回答2: Ok, so figured it out : From Here NSString *encoded_string = @"ü"; const char *ch = [encoded_string

问题 I have several UIButton 's together, and I want to adjust the font size so that it fits. However, each button should use the same font size so that they look the same. In other words, what I would like to do is set all button to the same minimum size. _button1.titleLabel.adjustsFontSizeToFitWidth = YES; _button2.titleLabel.adjustsFontSizeToFitWidth = YES; float minFont1 = _button1.titleLabel.font.pointSize; float minFont2 = _button2.titleLabel.font.pointSize; float fontSize = MIN(minFont1,

问题 I'm using a font here that has different looks for uppercase and lowercase numbers. This works perfectly in text editors, and Adobe's tools (by settings labels to uppercase only), and I figured this would work in UIKit as well by just running the string through the uppercaseString method, but it doesn't seem to actually turn the numbers into their uppercase versions.
