You can do it without any third-party libraries by using attributed text. I believe it does accept HTML fragments, like the one you’re getting, but you may want to wrap it in a complete HTML document so that you can specify CSS: static NSString *html = @”<html>” ” <head>” ” <style type=”text/css”>” ” body { … Read more
There’s an answer this question on objc.io in the “Intrinsic Content Size of Multi-Line Text” section of Advanced Auto Layout Toolbox. Here’s the relevant info: The intrinsic content size of UILabel and NSTextField is ambiguous for multi-line text. The height of the text depends on the width of the lines, which is yet to be … Read more
How about create new label and using sizeThatFit:(CGSize)size ?? UILabel *gettingSizeLabel = [[UILabel alloc] init]; gettingSizeLabel.font = [UIFont fontWithName:@”YOUR FONT’s NAME” size:16]; gettingSizeLabel.text = @”YOUR LABEL’s TEXT”; gettingSizeLabel.numberOfLines = 0; gettingSizeLabel.lineBreakMode = NSLineBreakByWordWrapping; CGSize maximumLabelSize = CGSizeMake(310, CGFLOAT_MAX); CGSize expectSize = [gettingSizeLabel sizeThatFits:maximumLabelSize]; Edit: This upper code is not good for ios 7 and above, … Read more
The correct answer is here: https://stackoverflow.com/a/43110590/566360 Embed the UILabel inside a UIView (Editor -> Embed In -> View) Use constraints to fit the UILabel to the UIView (for example, trailing space, top space, and leading space to superview constraints) The UIStackView will stretch out the UIView to fit properly, and the UIView will constrain the … Read more
I have written a custom truncating class that you can pop into you code where ever. Just use this method below. it will return true if truncation has taken place, and MaxWidth can be left as 0 if you just want to use the labels default frame width. Put maxWidth as something less than the … Read more
You have to implement protocols for that. Follow this: 1) In SettingView.h define protocol like this @protocol ViewControllerDelegate -(void) updateLabel; @end 2) Define property in .h class and synthesis in .m class.. @property (nonatomic, retain) id <ViewControllerDelegate> viewControllerDelegate; 3) In SettingsView.m IBAction -(IBAction)backToMain:(id) sender { [viewControllerDelegate updateLabel]; } 4) In ViewController.h adopt protocol like this … Read more
You could use a category to extend NSString and create the method you mention @interface NSString (visibleText) – (NSString*)stringVisibleInRect:(CGRect)rect withFont:(UIFont*)font; @end @implementation NSString (visibleText) – (NSString*)stringVisibleInRect:(CGRect)rect withFont:(UIFont*)font { NSString *visibleString = @””; for (int i = 1; i <= self.length; i++) { NSString *testString = [self substringToIndex:i]; CGSize stringSize = [testString sizeWithFont:font]; if (stringSize.height > … Read more
From: pulling an UIImage from a UITextView or UILabel gives white image. // iOS – (UIImage *)grabImage { // Create a “canvas” (image context) to draw in. UIGraphicsBeginImageContextWithOptions(self.bounds.size, self.opaque, 0.0); // high res // Make the CALayer to draw in our “canvas”. [[self layer] renderInContext: UIGraphicsGetCurrentContext()]; // Fetch an UIImage of our “canvas”. UIImage *image … Read more
The most simple way is to just add a gesture recognizer to the actual view (be it a UILabel or some custom view of your own). In order for the gesture recognizer to work, the view must be set userInteractionEnabled. Here’s an example, assuming that your label view (or whatever it is) is called labelView: … Read more
Set the following properties: Objective C label.adjustsFontSizeToFitWidth = NO; label.lineBreakMode = NSLineBreakByTruncatingTail; Swift label.adjustsFontSizeToFitWidth = false label.lineBreakMode = .byTruncatingTail You can also set these properties in interface builder.
