This seems to do the trick: UIBezierPath * imgRect = [UIBezierPath bezierPathWithRect:CGRectMake(0, 0, 100, 100)]; self.textView.textContainer.exclusionPaths = @[imgRect]; Works only from iOS 7 and up.
There is no need for using NSAttributedString. All you need is a simple label with the proper textColor. Plus this simple solution will work with all versions of iOS, not just iOS 6. But if you needlessly wish to use NSAttributedString, you can do something like this: UIColor *color = [UIColor redColor]; // select needed … Read more
You have to use NSBaselineOffsetAttributedName. From the doc: NSBaselineOffsetAttributeName The value of this attribute is an NSNumber object containing a floating point value indicating the character’s offset from the baseline, in points. The default value is 0. Available in iOS 7.0 and later. From your example: [buyString addAttribute:NSBaselineOffsetAttributeName value:@(10.0) range:NSMakeRange(2, buyString.length – 2)]; You may … Read more
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
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
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)];
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
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
Looks like you weren’t providing the correct options. For wrapping labels, provide at least: CGRect paragraphRect = [attributedText boundingRectWithSize:CGSizeMake(300.f, CGFLOAT_MAX) options:(NSStringDrawingUsesLineFragmentOrigin|NSStringDrawingUsesFontLeading) context:nil]; Note: if the original text width is under 300.f there won’t be line wrapping, so make sure the bound size is correct, otherwise you will still get wrong results.
