问题 I have a UILabel measuring 984x728 px with variable text. How can I calculate the maximum font size to fit the UILabel ? 回答1: Create a font larger than you would ever want (48 points is probably good). Then use this: CGFloat maxFontSize; [string sizeWithFont:font minFontSize:0 actualFontSize:&maxFontSize forWidth:maxWidth lineBreakMode: UILineBreakModeClip]; maxFontSize will hold the largest size less than 48 and greater than 0 that will fit within maxWidth . 来源： https://stackoverflow.com

问题 I have a background in iPhone development, which may be a cause of some of my confusion with Android, which I am very new at developing.

For example, on the iPhone, I would create a UILabel, generate a rectangular frame that specified the label's size and position, and then set this rectangle to the frame property of the UILabel.

Is there a way to add custom fonts to Xcode to be available from a storyboard? [duplicate]

由 别等时光非礼了梦想. 提交于 2020-01-05 10:13:09
问题 This question already has answers here : Designing labels/text views with custom fonts in Interface Builder (8 answers) Closed 5 years ago . I know how to add custom font files to be shipped with an iOS app. I can then customize the label font from code using code like this : UIFont* font = [UIFont fontWithName:@"League Gothic" size:42]; self.topLabel.font = font; My concern is that such customization will "infect" all of the project and may require some significant rework later on. Is there

UILabel text duplicates in PDF when containing a certain character

问题 I'm generating a PDF something like: UIGraphicsBeginPDFContextToFile layer.render(in: context) UIGraphicsEndPDFContext Yesterday, I found a fix to make all text vector-based (basically this answer https://stackoverflow.com/a/9056861/897465). That worked really well, text is vectors and searchable, etc. Except for one irritating thing. Everytime a UILabel contains the character "Å", the text is kind of duplicated in the PDF, like the image below. Probably there are other characters as well the

UILabel Refresh

问题 I have looked into this, but I’m still not quite clear how to do it. I have a UILabel. I would like to write out a word... letter by latter. It goes through each letter, then at the end the entire word shows up. At first I thought it was just because it was too fast, so I put in a delay with something like this. typedWord.text = [typedWord.text stringByAppendingString:@"C"]; future = [NSDate dateWithTimeIntervalSinceNow: letterPause ]; [NSThread sleepUntilDate:future]; Then I read that it may
