I'm trying to create attribute string with 2 fonts first is normal and second is bold.
NSMutableAttributedString *str = [[NSMutableAttributedString alloc] initWithString:message];
[str addAttribute:NSFontAttributeName value:[UIFont fontWithName:#"HelveticaNeue" size:10.0] range:firstRange];
[str addAttribute:NSFontAttributeName value:[UIFont fontWithName:#"HelveticaNeue-Bold" size:10.0] range:secondRange];
But It's show all text with normal text. I'm sure range is not the same.
How can I make it show normal and bold in 1 label.

I have a label and i set the text of the label programmatically. I want to set one of the word to be bold and the rest normal. However, i am unable to control the properties of the text. For example, I want this "This is an example" but am only able to achieve this "This is an example".
Try this:
NSString *text = #"This is an example";
NSString *textBold = #"example";
NSMutableAttributedString *attributedString = [[NSMutableAttributedString alloc] initWithString:text];
[attributedString beginEditing];
[attributedString addAttribute:NSFontAttributeName
value:[UIFont boldSystemFontOfSize:20.0f]
range:[text rangeOfString:textBold]];
[attributedString endEditing];
[labelObj setAttributedText:attributedString];
Take a look at the attributedText property of the label. It lets you assign styled text using an NSAttributedString. Explaining how to build an NSAttributedString is beyond the scope of an SO answer, but you should be able to find ample information both in the Xcode help system and online.
Let me show you a demo about the attributedText.
NSDictionary*subStrAttribute1 = #{
NSForegroundColorAttributeName: [UIColor redColor],
NSStrikethroughStyleAttributeName:#2
};
NSDictionary *subStrAttribute2 =#{
NSForegroundColorAttributeName: [UIColor greenColor]
};
NSString *strDisplayText3 =#"Red and Green";
NSMutableAttributedString *attributedText3 = [[NSMutableAttributedString alloc] initWithString:strDisplayText3];
[attributedText3 setAttributes:subStrAttribute1 range:NSMakeRange(0,3)];
[attributedText3 setAttributes:subStrAttribute2 range:NSMakeRange(8,5)];
self.lblInfo3.attributedText= attributedText3;
Since ios6 uilabel supports attributed strings, So you can use it.
For your particular case below code will work-
NSMutableAttributedString *string = [[NSMutableAttributedString alloc] initWithString:#"This is an example"];
[string addAttribute:NSFontAttributeName value:[UIFont fontWithName:#"HelveticaNeue-Bold" size:20.0] range:NSMakeRange(11, 7)];
label.attributedText = string;
I'm trying to disable any kind of kerning in UITextView
Somehow in arabic letters the text view kern the letters to fit the line but it just ruin the whole word, here's an examples:
textview has white background, and the code is:
NSString *aya =[mainArray objectAtIndex:indexPath.row];
cell.tx.text = aya;
[cell.tx sizeToFit];
cell.tx.frame = CGRectMake(5, 5, 265, cell.tx.frame.size.height);
cell.tx.backgroundColor = [UIColor whiteColor];
also tried to set NSMutableAttributedString NSKernAttributeName value but didn't work,,
---------------------Edit: This is the code for Kern Attribute:
NSMutableAttributedString *attributedString;
attributedString = [[NSMutableAttributedString alloc] initWithString:aya];
[attributedString addAttribute:NSKernAttributeName
value:#0.0
range:NSMakeRange(0,[aya length])];
[attributedString addAttribute:NSFontAttributeName
value:font
range:NSMakeRange(0,[aya length])];
NSMutableParagraphStyle *paragrapStyle = [NSMutableParagraphStyle new];
paragrapStyle.alignment = NSTextAlignmentRight;
[attributedString addAttribute:NSParagraphStyleAttributeName
value:paragrapStyle
range:NSMakeRange(0,[aya length])];
[cell.tx setAttributedText:attributedString];
It's a hack and I'm not near a computer to try it, but give this a shot:
Set the tx's text property
[tx setText:aya];
Create an NSMutableAttributedString from the text view's text
NSMutableAttributedString *attrStr = [[tx attributedText] mutableCopy];
Set the kern attribute on the attributed string
[attrStr setAttributes:#{ NSKernAttributeName: #(0.f) }
range:NSMakeRange(0, [attrStr length])];
Set the attrStr back on tx
[tx setAttributedText:attrStr];
This will (hopefully) preserve the attributes UITextView infers from your NSString.
I have a text label inside a UITableViewCell consisting of two words.
How can I change the color of the words; making the first word green, and the second word red?
NSString *twoWords = #"Green Red";
NSArray *components = [twoWords componentsSeparatedByString:#" "];
NSRange greenRange = [twoWords rangeOfString:[components objectAtIndex:0]];
NSRange redRange = [twoWords rangeOfString:[components objectAtIndex:1]];
NSMutableAttributedString *attrString = [[NSMutableAttributedString alloc] initWithString:twoWords];
[attrString beginEditing];
[attrString addAttribute: NSForegroundColorAttributeName
value:[UIColor greenColor]
range:greenRange];
[attrString addAttribute: NSForegroundColorAttributeName
value:[UIColor redColor]
range:greenRange];
[attrString endEditing];
Then you can use attrString directly on a UILabel (> iOS 6, check Apple Documentation).
The simplest way to do this would be with an nsattributedstring in iOS 6.0 or later. You would allocate one of those and in the titleLabel (or any other object that holds text) of the UITableViewCell. If you're using the titleLabel you would do this:
[cell.titleLabel setAttributedText:yourAttributedString];
To setup the colors with an NSAttributedString, do this:
NSMutableAttributedString* attributedString = [[NSMutableAttributedString alloc] initWithString:stringToManipulate];
[attributedString beginEditing];
[attributedString addAttribute:NSForegroundColorAttributeName value:[UIColor greenColor] range:NSMakeRange(0, widthOfFisrtWord)];
[attributedString addAttribute:NSForegroundColorAttributeName value:[UIColor redColor] range:NSMakeRange(widthOfFisrtWord, widthOfSecondWord)];
[attributedString endEditing];
Note that the ranges provided above using NSMakeRange won't be the ranges you need. You'll have to change the range to fit your own needs depending if the two words have a space in between them or other characters.

This question addresses getting part of a string, which you would need to do. Instead of modifying the text with BOLD though, you can use this question to get an idea of how to change the color.
By using NSAttributedString string you can set two different colors.NSAttributedString
once check this one.
I have a TextView in which I need some text to change colors and fonts. Any method is available other than core text. Please help.
i need some text to change colors and fonts.
You certainly looking for NSAttributedString
From Source
NSMutableAttributedString *str = [[NSMutableAttributedString alloc] initWithString:#"Hello. That is a test attributed string."];
[str addAttribute:NSBackgroundColorAttributeName value:[UIColor yellowColor] range:NSMakeRange(3,5)];
[str addAttribute:NSForegroundColorAttributeName value:[UIColor greenColor] range:NSMakeRange(10,7)];
[str addAttribute:NSFontAttributeName value:[UIFont fontWithName:#"HelveticaNeue-Bold" size:20.0] range:NSMakeRange(20, 10)];
label.attributedText = str;
I want to format the test in my textview, some texts in bold some thing in italic like that. Is it possible for uitextview?
Right now I'm using webview with HTML strings.
eg:
<html><head><style type=\"text/css\">h3 {color:white;} p {color:pink;} p {text-align: center} p {font-family:helvetica;font-size:20px;}</style></head><body>\
<h3></h3>\
<p><b>some text </b></p>\
<p>Short some text</p>\
<p>Child Infusion 7.5 to 15 mg/kg/hr<br>ie 7.5 to 15 times weight per hour</p>\
<p>Adult Infusion 3 to 12 mg/kg/hr<br>ie 3 to 12 mg times weight per hour</p>\
</body></html>
You can use NSAttributedString, Set Text Font, Foreground And Background Colors, StrikeThrough And Shadow etc..
Attributed strings make an association between characters and their attributes. Like NSString objects, there are two variations, NSAttributedString and NSMutableAttributedString.
Although previous versions of iOS supported attributed strings, it wasn’t until iOS 6 that controls such as buttons, labels, textfields and textviews defined a property to manage attributes.
Attributes are applied to a range of characters, so you can for example, set a strikethrough attribute for just a portion of a string. It’s also important to note that the default font for attributed string objects is Helvetica 12-point. Keep this in mind if you set the font attribute for a range other than the complete string.
The following attributes can be set with attributed strings:
NSString *const NSFontAttributeName;
NSString *const NSParagraphStyleAttributeName;
NSString *const NSForegroundColorAttributeName;
NSString *const NSBackgroundColorAttributeName;
NSString *const NSLigatureAttributeName;
NSString *const NSKernAttributeName;
NSString *const NSStrikethroughStyleAttributeName;
NSString *const NSUnderlineStyleAttributeName;
NSString *const NSStrokeColorAttributeName;
NSString *const NSStrokeWidthAttributeName;
NSString *const NSShadowAttributeName;
NSString *const NSVerticalGlyphFormAttributeName;
here are some examples
//-----------------------------
// Create attributed string
//-----------------------------
NSString *str = #"example for underline \nexample for font \nexample for bold \nexample for italics";
NSMutableAttributedString *attributedString = [[NSMutableAttributedString alloc] initWithString:str];
// Add attribute NSUnderlineStyleAttributeName
//[attributedString addAttribute:NSUnderlineStyleAttributeName value:[NSNumber numberWithInt:NSUnderlineStyleSingle] range:NSMakeRange(12, 9)];
[attributedString addAttribute:NSUnderlineStyleAttributeName value:[NSNumber numberWithInt:NSUnderlineStyleSingle] range:NSMakeRange(12, 9)];
// Set background color for entire range
[attributedString addAttribute:NSBackgroundColorAttributeName
value:[UIColor yellowColor]
range:NSMakeRange(0, [attributedString length])];
// Create NSMutableParagraphStyle object
NSMutableParagraphStyle *paragraph = [[NSMutableParagraphStyle alloc] init];
paragraph.alignment = NSTextAlignmentCenter;
// Add attribute NSParagraphStyleAttributeName
[attributedString addAttribute:NSParagraphStyleAttributeName value:paragraph range:NSMakeRange(0, [attributedString length])];
// Set font, notice the range is for the whole string
UIFont *font = [UIFont fontWithName:#"Helvetica" size:18];
[attributedString addAttribute:NSFontAttributeName value:font range:NSMakeRange(35, 4)];
// Set font, notice the range is for the whole string
UIFont *fontBold = [UIFont fontWithName:#"Helvetica-Bold" size:18];
[attributedString addAttribute:NSFontAttributeName value:fontBold range:NSMakeRange(53, 4)];
// Set font, notice the range is for the whole string
UIFont *fontItalics = [UIFont fontWithName:#"Helvetica-Oblique" size:18];
[attributedString addAttribute:NSFontAttributeName value:fontItalics range:NSMakeRange(71, 7)];
// Set label text to attributed string
[self.mytextView setAttributedText:attributedString];
