Can I set the `attributedText` property of `UILabel` - ios

Question

Can I set the attributedText property of a UILabel object? I tried the below code:
UILabel *label = [[UILabel alloc] init];
label.attributedText = #"asdf";
But it gives this error:
Property "attributedText" not found on object of type 'UILabel *'
#import <CoreText/CoreText.h> not working

Answer 1

Here is a complete example of how to use an attributed text on a label:
NSString *redText = #"red text";
NSString *greenText = #"green text";
NSString *purpleBoldText = #"purple bold text";
NSString *text = [NSString stringWithFormat:#"Here are %#, %# and %#",
redText,
greenText,
purpleBoldText];
// If attributed text is supported (iOS6+)
if ([self.label respondsToSelector:#selector(setAttributedText:)]) {
// Define general attributes for the entire text
NSDictionary *attribs = #{
NSForegroundColorAttributeName: self.label.textColor,
NSFontAttributeName: self.label.font
};
NSMutableAttributedString *attributedText =
[[NSMutableAttributedString alloc] initWithString:text
attributes:attribs];
// Red text attributes
UIColor *redColor = [UIColor redColor];
NSRange redTextRange = [text rangeOfString:redText];// * Notice that usage of rangeOfString in this case may cause some bugs - I use it here only for demonstration
[attributedText setAttributes:#{NSForegroundColorAttributeName:redColor}
range:redTextRange];
// Green text attributes
UIColor *greenColor = [UIColor greenColor];
NSRange greenTextRange = [text rangeOfString:greenText];// * Notice that usage of rangeOfString in this case may cause some bugs - I use it here only for demonstration
[attributedText setAttributes:#{NSForegroundColorAttributeName:greenColor}
range:greenTextRange];
// Purple and bold text attributes
UIColor *purpleColor = [UIColor purpleColor];
UIFont *boldFont = [UIFont boldSystemFontOfSize:self.label.font.pointSize];
NSRange purpleBoldTextRange = [text rangeOfString:purpleBoldText];// * Notice that usage of rangeOfString in this case may cause some bugs - I use it here only for demonstration
[attributedText setAttributes:#{NSForegroundColorAttributeName:purpleColor,
NSFontAttributeName:boldFont}
range:purpleBoldTextRange];
self.label.attributedText = attributedText;
}
// If attributed text is NOT supported (iOS5-)
else {
self.label.text = text;
}

Unfortunately, UILabel doesn't support attributed strings. You can use OHAttributedLabel instead.
Update: Since iOS6, UILabel does support attributed strings. See UILabel reference or Michael Kessler's answer below for more details.

Answer 3

NSString *str1 = #"Hi Hello, this is plain text in red";
NSString *cardName = #"This is bold text in blue";
NSString *text = [NSString stringWithFormat:#"%#\n%#",str1,cardName];
// Define general attributes for the entire text
NSDictionary *attribs = #{
NSForegroundColorAttributeName:[UIColor redColor],
NSFontAttributeName: [UIFont fontWithName:#"Helvetica" size:12]
};
NSMutableAttributedString *attributedText = [[NSMutableAttributedString alloc] initWithString:text attributes:attribs];
UIFont *boldFont = [UIFont fontWithName:#"Helvetica-Bold" size:14.0];
NSRange range = [text rangeOfString:cardName];
[attributedText setAttributes:#{NSForegroundColorAttributeName: [UIColor blueColor],
NSFontAttributeName:boldFont} range:range];
myLabel = [[UILabel alloc] initWithFrame:CGRectZero];
myLabel.attributedText = attributedText;

Answer 4

for Swift 4:
iOS 11 and xcode 9.4
let str = "This is a string which will shortly be modified into AtrributedString"
var attStr = NSMutableAttributedString.init(string: str)
attStr.addAttribute(.font,
value: UIFont.init(name: "AppleSDGothicNeo-Bold", size: 15) ?? "font not found",
range: NSRange.init(location: 0, length: str.count))
self.textLabel.attributedText = attStr

Answer 5

For people using swift, here's a one-liner:
myLabel.attributedText = NSMutableAttributedString(string: myLabel.text!, attributes: [NSFontAttributeName:UIFont(name: "YourFont", size: 12), NSForegroundColorAttributeName: UIColor.whiteColor()])

Answer 6

so,here is the code to have different properties for sub strings ,of a string.
NSString *str=#"10 people likes this";
NSString *str2=#"likes this";
if ([str hasSuffix:str2])
{
NSMutableAttributedString * string = [[NSMutableAttributedString alloc] initWithString:str];
// for string 1 //
[string addAttribute:NSForegroundColorAttributeName value:[UIColor blueColor] range:NSMakeRange(0,str.length-str2.length)];
[string addAttribute:NSFontAttributeName value:[UIFont boldSystemFontOfSize:14] range:NSMakeRange(0,str.length-str2.length)];
// for string 2 //
[string addAttribute:NSForegroundColorAttributeName value:[UIColor greenColor] range:NSMakeRange((str.length-str2.length),str2.length)];
[string addAttribute:NSFontAttributeName value:[UIFont italicSystemFontOfSize:12] range:NSMakeRange((str.length-str2.length),str2.length)];
label.attributedText=string;
}
else
{
label.text =str;
}

Answer 7

Hope this helps ;)
NSMutableAttributedString* attrStr = [NSMutableAttributedString attributedStringWithString:#"asdf"];
[attrStr setFont:[UIFont systemFontOfSize:12]];
[attrStr setTextColor:[UIColor grayColor]];
[attrStr setTextColor:[UIColor redColor] range:NSMakeRange(0,5)];
lbl.attributedText = attrStr;

UIFont *font = [UIFont boldSystemFontOfSize:12];
NSDictionary *fontDict = [NSDictionary dictionaryWithObject: font forKey:NSFontAttributeName];
NSMutableAttributedString *attrString = [[NSMutableAttributedString alloc] initWithString:#" v 1.2.55" attributes: fontDict];
UIFont *fontNew = [UIFont boldSystemFontOfSize:17];
NSDictionary *fontDictNew = [NSDictionary dictionaryWithObject: fontNew forKey:NSFontAttributeName];
NSMutableAttributedString *attrStringNew = [[NSMutableAttributedString alloc] initWithString:#“Application” attributes: fontDictNew];
[attrStringNew appendAttributedString: attrString];
self.vsersionLabel.attributedText = attrStringNew;
