I want to add an image in start of UILabel. Label is multiline. If I use contentInset, it indent the whole label but I want to indent first line only.
I have tried this so far, this doesn't work for me.
UIEdgeInsets titleInsets = UIEdgeInsetsMake(0.0, 40.0, 0.0, 0.0);
valueLabel.contentInset = titleInsets;
It should look like this.
#DavidCaunt suggestion worked for me. I am sharing code here.
NSMutableParagraphStyle *style = [[NSMutableParagraphStyle alloc] init];
style.firstLineHeadIndent = 50;
[attributedText addAttribute:NSParagraphStyleAttributeName value:style range:range];
[valueLabel setAttributedText:attributedText];
As a user716216 pointed, additionally - we can use a tab with defined indent value:
NSMutableParagraphStyle *paragraphStyle = [NSMutableParagraphStyle new];
paragraphStyle.headIndent = 50;
label.attributedText = [[NSAttributedString alloc] initWithString:
#"\tHow can i add image like this in start of UILabel? Label is multiline.........."
attributes:#{NSParagraphStyleAttributeName: paragraphStyle}];
Here's how you can do this in Interface Builder:

Team,
I have UITextView added content of text, with font family avinar roma, I noticed there is small gap in between each word which was not consistent. How to avoid the small gap in textview text for each word.
descriptionTextView = [[UITextView alloc] initWithFrame:CGRectMake(20, titlelabel.frame.origin.y + titlelabel.frame.size.height + 5, view.frame.size.width - 40, view.frame.size.height - 150)];
descriptionTextView.backgroundColor = [UIColor clearColor];
descriptionTextView.textColor = MH_PANTONE_444;
descriptionTextView.textAlignment = NSTextAlignmentCenter;
descriptionTextView.font = [UIFont fontWithName:MH_FONT_AVENIRROMAN size:MH_SCREEN_HEIGHT/48];
descriptionTextView.text = [descriptionArray objectAtIndex:index];
descriptionTextView.editable = NO;
descriptionTextView.scrollEnabled = NO;
descriptionTextView.selectable = YES;
descriptionTextView.dataDetectorTypes = UIDataDetectorTypeAll;
Please have image attached above
University Medical Center, is not same gap with remaining text.
Setting the hyphenationFactor should fix your problem. But you have to use NSAttributedString instead of plain text:
UIFont *font = [UIFont fontWithName: MH_FONT_AVENIRROMAN size: MH_SCREEN_HEIGHT/48];
NSMutableParagraphStyle *paragraphStyle = [[NSMutableParagraphStyle alloc] init];
paragraphStyle.hyphenationFactor = 1.0;
NSDictionary *attributes = #{ NSFontAttributeName:font,
NSForegroundColorAttributeName: MH_PANTONE_444;
NSParagraphStyleAttributeName: paragraphStyle };
NSMutableAttributedString *attributedText = [[NSMutableAttributedString alloc] initWithString: [descriptionArray objectAtIndex:index]
attributes: attributes];
descriptionTextView.attributedText = attributedText;
https://developer.apple.com/reference/uikit/nsmutableparagraphstyle/1535553-hyphenationfactor
You may have to adjust the hyphenationFactor until you get the result you want. (0.0-1.0)
I solved the same issue by setting the leftView property of the UITextField to be an empty view with the size of the padding as desired:
UIView *paddingView = [[UIView alloc] initWithFrame:CGRectMake(0, 0, 5, 20)];
textView.leftView = paddingView;
textView.leftViewMode = UITextFieldViewModeAlways;
I had also face an issue of text alignment with custom fonts in iOS application, and that was with vertical alignment. I guess this is because of the custom font you are using in your application. But luckily there is a solution.
Every font file have some configurations about display the letter. One of the property is minLeftSideBearing for left spacing and minRightSideBearing for right spacing. I guess by changing them you can solve this spacing issue.
Follow the following link to check how to change this properties.
http://www.andyyardley.com/2012/04/24/custom-ios-fonts-and-how-to-fix-the-vertical-position-problem/
And as mention in above blog you need to install font tool. That you can download from following link.

Hope this might help you.
Thanks, Jay.
The dots are added automatically by the UILabel, cause of line limitation, but they get the background color of hidden truncated text:
So I have UILabel with line limit of 10 and line break mode of TruncatingTail.
I also have 2 types of attributed strings that build this UILabel content.
NSForegroundColorAttributeName, NSFontAttributeName
NSBackgroundColorAttributeName, NSForegroundColorAttributeName, NSFontAttributeName
Any idea why the UILabel is adding background color to the dots? There is text in line 12 (which is truncated) that have that background...
=Here Given Code Try it..
NSMutableAttributedString *text = [[NSMutableAttributedString alloc] initWithString:#"test"];
NSMutableParagraphStyle *style = [[NSMutableParagraphStyle alloc] init];
style.lineBreakMode = NSLineBreakByTruncatingTail;
[text addAttribute:NSParagraphStyleAttributeName
value:style
range:NSMakeRange(0, text.length)];
label.attributedText = text;
It looks like your NSAttributedString styling is picking up on an instance of "Windsor" that is past the truncation point.
You could find where the truncation occurs, and then only apply the text attribute to the range of the string up to the truncation point.
See this SO answer to calculate this range.
NSMutableParagraphStyle *paragraph = [[NSMutableParagraphStyle alloc] init];
paragraph.lineBreakMode = mylabel.lineBreakMode;
NSDictionary *attributes = #{NSFontAttributeName : mylabel.font,
NSParagraphStyleAttributeName : paragraph};
CGSize constrainedSize = CGSizeMake(mylabel.bounds.size.width, NSIntegerMax);
CGRect rect = [mylabel.text boundingRectWithSize:constrainedSize
options:(NSStringDrawingUsesLineFragmentOrigin|NSStringDrawingUsesFontLeading)
attributes:attributes context:nil];
if (rect.size.height > mylabel.bounds.size.height) {
NSLog(#"TOO MUCH");
}
Is there a a way to modify the line width of the underline an NSAttributedString?
It seems I can easily modify the color but I can't modify the width of the underline itself easily.
You can set NSUnderlineStyleThick or NSUnderlineStyleSingle, eg:
NSAttributedString *str = [[NSAttributedString alloc] initWithString:#"Thick underline" attributes:#{NSUnderlineStyleAttributeName: #(NSUnderlineStyleThick)}];
NSAttributedString *str = [[NSAttributedString alloc] initWithString:#"Normal underline" attributes:#{NSUnderlineStyleAttributeName: #(NSUnderlineStyleSingle)}];
Full list of underline styles here: https://developer.apple.com/library/prerelease/ios/documentation/UIKit/Reference/NSAttributedString_UIKit_Additions/index.html#//apple_ref/c/tdef/NSUnderlineStyle
// assume Label name as "label"
// underline code
CGSize expectedLabelSize = [#"Some text" sizeWithFont:label.font constrainedToSize:label.frame.size lineBreakMode:UILineBreakModeWordWrap];
UIView *viewForUnderline=[[UIView alloc] init];
viewForUnderline.frame=CGRectMake((label.frame.size.width - expectedLabelSize.width)/2, expectedLabelSize.height + (label.frame.size.height - expectedLabelSize.height)/2, expectedLabelSize.width, 1);
viewForUnderline.backgroundColor=[UIColor whiteColor];
[self.view addSubview:viewForUnderline];
or you can use following line of code
label.attributedText = [[NSAttributedString alloc] initWithString:#"Some Text"
attributes:underlineAttribute];
In my UITextView, I want certain NSRanges to be indented left and right equally and be highlighted in a specific color. I am achieving this by modifying NSMutableAttributedStrings and setting the textView.attributedText. To get the left/right indentation, I'm using NSMutableParagraphStyle - however, this is removing the highlighting (NSBackgroundColor). How can I get it such that the highlighting starts from the beginning, even with the headIndent.
// padding
NSMutableParagraphStyle *paragraphStyle = [[NSMutableParagraphStyle alloc] init];
paragraphStyle.headIndent = 5.0;
paragraphStyle.firstLineHeadIndent = 5.0;
paragraphStyle.tailIndent = -5.0;
NSDictionary *referenceAttributes = #{NSForegroundColorAttributeName: [UIColor lightGrayColor], NSBackgroundColorAttributeName: [UIColor brownColor], NSFontAttributeName: [UIFont fontWithName:#"HelveticaNeue-Bold" size: 14], NSParagraphStyleAttributeName: paragraphStyle};
Use following code to give padding in UITextView
self.textView.textContainer.lineFragmentPadding = 0;
I am attempting to have a multiline NSAttributedString, with a line spacing of 1.25.
NSMutableParagraphStyle *bodyFormat = [[NSMutableParagraphStyle alloc] init];
bodyFormat.alignment = NSTextAlignmentLeft;
//[bodyFormat setLineSpacing:5];
[bodyFormat setLineBreakMode:NSLineBreakByWordWrapping];
//[bodyFormat setMaximumLineHeight:5];
[bodyFormat setLineHeightMultiple:1.25];
NSMutableAttributedString *desc = [[NSMutableAttributedString alloc] initWithString:#"So why to use Lorem Ipsum and why placeholder text is necessary? Naturally, page designs that are made for text documents must contain some text rather than placeholder dots or something else. Howevr, should they contain a proper English words and sentenses almost every reader will deliberately try to interpret it eventually missing the design itself"];
[desc addAttribute:NSParagraphStyleAttributeName value:bodyFormat range:NSMakeRange(0, desc.length)];
UILabel *description = [[UILabel alloc] initWithFrame:CGRectMake(0,
20,
300,
1000)];
description.lineBreakMode = NSLineBreakByWordWrapping;
[description setAttributedText:desc];
[self.view addSubview:description];
This manages to produce a single line, and the linebreak is not effective.
What am I doing wrong?
[bodyFormat setLineSpacing:5];
breaks this behavior.
Also setting
description.numberOfLines = 0;
helps... (description is the UILabel)
