According to the documentation of enumerateAttribute:inRange:options:usingBlock:, especially the Discussion part which states: If this method is sent to an instance of NSMutableAttributedString, mutation (deletion, addition, or change) is allowed, as long as it is within the range provided to the block; after a mutation, the enumeration continues with the range immediately following the processed range, … Read more
I also faced this issue, I fixed it by iterating to the attributes and reseting the old font size as follows NSMutableAttributedString *res = [attributedText mutableCopy]; [res beginEditing]; [res enumerateAttribute:NSFontAttributeName inRange:NSMakeRange(0, res.length) options:0 usingBlock:^(id value, NSRange range, BOOL *stop) { if (value) { UIFont *oldFont = (UIFont *)value; UIFont *newFont = [oldFont fontWithSize:15]; [res addAttribute:NSFontAttributeName … Read more
The following code seems to do the trick: UIFont *fnt = [UIFont fontWithName:@”Helvetica” size:20.0]; NSMutableAttributedString *attributedString = [[NSMutableAttributedString alloc] initWithString:@”GGG®GGG” attributes:@{NSFontAttributeName: [fnt fontWithSize:20]}]; [attributedString setAttributes:@{NSFontAttributeName : [fnt fontWithSize:10] , NSBaselineOffsetAttributeName : @10} range:NSMakeRange(3, 1)];
Something like this should work: NSMutableAttributedString *res = [self.richTextEditor.attributedText mutableCopy]; [res beginEditing]; __block BOOL found = NO; [res enumerateAttribute:NSFontAttributeName inRange:NSMakeRange(0, res.length) options:0 usingBlock:^(id value, NSRange range, BOOL *stop) { if (value) { UIFont *oldFont = (UIFont *)value; UIFont *newFont = [oldFont fontWithSize:oldFont.pointSize * 2]; [res removeAttribute:NSFontAttributeName range:range]; [res addAttribute:NSFontAttributeName value:newFont range:range]; found = YES; } … Read more
You can do this using NSAttributedString Example: let underlineAttribute = [NSAttributedString.Key.underlineStyle: NSUnderlineStyle.thick.rawValue] let underlineAttributedString = NSAttributedString(string: “StringWithUnderLine”, attributes: underlineAttribute) myLabel.attributedText = underlineAttributedString EDIT To have the same attributes for all texts of one UILabel, I suggest you to subclass UILabel and overriding text, like that: Swift 5 Same as Swift 4.2 but: You should prefer … Read more
I can answer my own question now: I am using UITextView instead of UILabel now. I have formatted the UITextView to look and behave like my labels and added: UITextView *textView = [[UITextView alloc] init]; textView.scrollEnabled = NO; textView.editable = NO; textView.textContainer.lineFragmentPadding = 0; textView.textContainerInset = UIEdgeInsetsMake(0, 0, 0, 0); textView.delegate = self; Don’t forget … Read more
You would do something like this… NSMutableAttributedString *hogan = [[NSMutableAttributedString alloc] initWithString:@”Presenting the great… Hulk Hogan!”]; [hogan addAttribute:NSFontAttributeName value:[UIFont systemFontOfSize:20.0] range:NSMakeRange(24, 11)]; This will set the last two words in 20-point text; the rest of the string will use the default value (which I believe is 12 points). The thing that might be confusing about … Read more
Yes you need to use NSAttributedString for that, find the RunningAppHere. Scan through the word and find the range of your word and change its color. EDIT: – (IBAction)colorWord:(id)sender { NSMutableAttributedString * string = [[NSMutableAttributedString alloc]initWithString:self.text.text]; NSArray *words=[self.text.text componentsSeparatedByString:@” “]; for (NSString *word in words) { if ([word hasPrefix:@”@”]) { NSRange range=[self.text.text rangeOfString:word]; [string addAttribute:NSForegroundColorAttributeName … Read more
Reference from here. First of all initialize of you NSString and NSMutableAttributedString as below. var myString:NSString = “I AM KIRIT MODI” var myMutableString = NSMutableAttributedString() In ViewDidLoad override func viewDidLoad() { myMutableString = NSMutableAttributedString(string: myString, attributes: [NSFontAttributeName:UIFont(name: “Georgia”, size: 18.0)!]) myMutableString.addAttribute(NSForegroundColorAttributeName, value: UIColor.redColor(), range: NSRange(location:2,length:4)) // set label Attribute labName.attributedText = myMutableString super.viewDidLoad() } OUTPUT MULTIPLE … Read more
You have to enumerate the NSAttributedString looking for NSTextAttachments. NSMutableArray *imagesArray = [[NSMutableArray alloc] init]; [attributedString enumerateAttribute:NSAttachmentAttributeName inRange:NSMakeRange(0, [attributedString length]) options:0 usingBlock:^(id value, NSRange range, BOOL *stop) { if ([value isKindOfClass:[NSTextAttachment class]]) { NSTextAttachment *attachment = (NSTextAttachment *)value; UIImage *image = nil; if ([attachment image]) image = [attachment image]; else image = [attachment imageForBounds:[attachment bounds] … Read more
