ios - SizeToFit on UIImageView not working

由 回眸只為那壹抹淺笑 提交于 2020-01-02 06:19:13
问题 I have a UIImageView which loads in images from the documents directory on the ios file system . The problem is that when I call [imageView sizeToFit]; It does not work. I think it is because the image hasn't loaded fully at that point and so the sizeToFit part is called before it has the image width & height. Could someone point me in the direction of a fix please. Here is my code: imageView.contentMode = UIViewContentModeScaleAspectFit; imageView.image = [UIImage imageWithContentsOfFile:

CATextLayer wrapped sizeToFit?

问题 If I set textLayer.wrapped = YES , how do I resize textLayer to contain the wrapped text? I.e., how do I get the new height of the textLayer ? Basically, I want something like -[UILabel sizeToFit] . 回答1: The first thing you need to do is get the size of the text. Thankfully, the NSString UIKit Additions Reference offers a method to do exactly that: - (CGSize)sizeWithFont:(UIFont *)font constrainedToSize:(CGSize)size lineBreakMode:(UILineBreakMode)lineBreakMode That will give you a CGSize that

In iOS - How do I fit a UILabel to its text, without changing its position?

由 a 夏天 提交于 2019-12-12 09:36:19
问题 I'm calling sizeToFit on a UILabel which has right aligned text in it. It shrinks the height and width of the UILabel and fits the text to the top left of the UILabel . Now...the position of the UILabel is incorrect. How can I make the UILabel stay in its original position (right aligned) or move it so it'll appear at its original position? Once again - the problem is that the sizeToFit method is shrinking the width from the right side of the UILabel . It is treating the UILabel text as left

AdjustsFontSizeToFitWidth vs. SizeToFit

由 本小妞迷上赌 提交于 2019-12-10 11:29:29
问题 I'm using SizeToFit because I don't have to specify the Frame property to have an adaptive size of the UIButton / UILabel . In my case it's a button on a toolbar. Now I made the following observation: If I use AdjustsFontSizeToFitWidth together with SizeToFit than the font size isn't adapted anymore. So I can Specify a Frame and use AdjustsFontSizeToFitWidth Use SizeToFit but don't have the adjustable font size anymore Do you also have this problem? How do you circumvent this problem? How to
