I have a string:
NSString *userInfo = #"James Johnson #james";
What i want to do is bold James Johnson and keep #james normal font.
So what I have tried is using NSAttributedString but somewhere I'm doing something wrong in order to complete the process.
This is what I have tried:
NSString *user = #"James Johnson #james";
UIFont *fontLight = [UIFont fontWithName:#"HelveticaNeue-Light" size:14];
UIFont *fontBold = [UIFont fontWithName:#"HelveticaNeue-Bold" size:14];
NSMutableAttributedString *string = [[NSMutableAttributedString alloc]initWithString:userInfo];
//TESTING WITH RANDOM PARTS OF THE STRIN
[string addAttribute:NSForegroundColorAttributeName value:fontLight range:NSMakeRange(0, 3)];
[string addAttribute:NSForegroundColorAttributeName value:fontBold range:NSMakeRange(3, 5)];
NSString *str = [string string];
cell.textLabel.text = str;
Is there a way I can make this work even if I'm on the wrong direction?
What's not working
For some reason, the characters from range 0 - 3 is not being a light font...instead the entire cell.textLabel.text is bold somehow and is not font size 14 which i had specified in the UIFont.
Your last part of it is wrong. You must create your NSAttributedString and finally trash the formatting by using
NSString *str = [string string];
As NSString doesn't know anything about formatting you have to use the NSAttributedString to assign it to the cell's textLabel:
cell.textLabel.attributedText = string;
You should set attributedString to attributed text
Comment these lines
//NSString *str = [string string];
//cell.textLabel.text = str;
And write this
cell.textLabel.attributedText = string;//Set NSMutableAttributedString only not NSString
UILabel has a property attributedText. You should be assigning this property with your attributed string and not use text property.
Make changes in you code as follows :
You will require to report all the characters with in the NSMutableAttributedString, so specify them with in the range, while adding an attribute.
Provide correct attribute name, else you will have an exception here, in this case you should use "NSFontAttribteName" in place of "NSForegroundColorAttributeName".
NSString *user = #"James Johnson #james";
UIFont *fontLight = [UIFont fontWithName:#"HelveticaNeue-Light" size:14];
UIFont *fontBold = [UIFont fontWithName:#"HelveticaNeue-Bold" size:14];
NSMutableAttributedString *string = [[NSMutableAttributedString alloc]initWithString:user];
[string addAttribute:NSFontAttributeName value:fontLight range:NSMakeRange(0, 20)];
[string addAttribute:NSFontAttributeName value:fontBold range:NSMakeRange(0, 5)];
cell.textLabel.attributedText = string;

I have looked online for ways to bold a NSString and either it's not there or I can't seem to find it. I simply want to bold the word in the NSString but so far, what I have done is not woking:
NSString *player1Name = [[UIFont boldSystemFontOfSize:12] fontName];
I have relied on this to make "player1Name" bold but it doesn't work at all.
When I run it I get this:
Thanks in advance to anyone who helps me figure out the solution.
You can not bold a NSString... Try a NSAttributedString...
NSAttributedString *player1Name = [[NSAttributedString alloc] initWithString:#"name" attributes:#{NSFontAttributeName : [UIFont boldSystemFontOfSize:12]}];
https://developer.apple.com/library/ios/documentation/Cocoa/Reference/Foundation/Classes/NSAttributedString_Class/
fontName is a property on UIFont
[[UIFont boldSystemFontOfSize:12] fontName]
returns the font name HelveticaNeueInterface-MediumP4
Try this:
NSString *myString = #"My string!";
NSAttributedString *myBoldString = [[NSAttributedString alloc] initWithString:myString
attributes:#{ NSFontAttributeName: [UIFont boldSystemFontOfSize:35.0] }];
Also you can set range for particular text like:
NSString *boldFontName = [[UIFont boldSystemFontOfSize:12] fontName];
NSString *yourString = ...;
NSRange boldedRange = NSMakeRange(2, 4);
NSMutableAttributedString *attrString = [[NSMutableAttributedString alloc] initWithString:yourString];
[attrString beginEditing];
[attrString addAttribute:kCTFontAttributeName
value:boldFontName
range:boldedRange];
[attrString endEditing];
You can't make NSString bold. Instead of that you can make UILabel text into bold. Because UILabels are for UI representation & NSStrings are just objects. So make your UILabel bold
[infoLabel setFont:[UIFont boldSystemFontOfSize:16]];
Hi I am doing one application. In that I need to show text in different fonts. I mean if I show name in one font and I show city name in different font.
UITextView *textView = [[UITextView alloc] initWithFrame:CGRectMake(50, 50, 200, 100)];
textView.text = #"Vijay Apple Dev";
NSString *textViewText = textView.text;
NSMutableAttributedString *attributedText = [[NSMutableAttributedString alloc] initWithString:textViewText];
[attributedText addAttribute:NSFontAttributeName
value:[UIFont fontWithName:#"Courier" size:20]
range:[textViewText rangeOfString:#"Apple"]];
[attributedText addAttribute:NSFontAttributeName
value:[UIFont fontWithName:#"Verdana" size:20]
range:[textViewText rangeOfString:#"Vijay"]];
textView.attributedText = attributedText;
[self.view addSubview:textView];
Try to do like this one... And customize according to your requirement like font name and font size
NSString *firstName = #"FirstName";
NSMutableAttributedString *attributedString = [[NSMutableAttributedString alloc] initWithString:firstName];
UIFont *font = [UIFont fontWithName:#"Helvetica" size:20];
[attributedString addAttribute:NSFontAttributeName value:font range:NSMakeRange(0, firstName.length)];// Here define your range.
textView.attributedText = attributedString;
//Use attributed String
//Apply properties to both strings
//then merge and set it to textview
NSString *selectedString=#"Hey,";
UIFont *fontSelectedText = [UIFont boldSystemFontOfSize:25];
NSDictionary *dictBoldSelectedText = [NSDictionary dictionaryWithObjectsAndKeys:fontSelectedText, NSFontAttributeName, nil];
NSMutableAttributedString *mutAttrTextViewSelectedString = [[NSMutableAttributedString alloc] initWithString:selectedString];
[mutAttrTextViewSelectedString setAttributes:dictBoldSelectedText range:NSMakeRange(0,selectedString.length)];
[_tTextView setAttributedText:mutAttrTextViewSelectedString];
//Second String
NSString *restOfStrig=#"\nHello";
NSMutableAttributedString *mutAttrTextViewString = [[NSMutableAttributedString alloc] initWithString:restOfStrig];
UIFont *fontText = [UIFont boldSystemFontOfSize:16];
NSDictionary *dictBoldText = [NSDictionary dictionaryWithObjectsAndKeys:fontText, NSFontAttributeName, nil];
[mutAttrTextViewString setAttributes:dictBoldText range:NSMakeRange(0,restOfStrig.length)];
//Combining both the Attributed String
[mutAttrTextViewSelectedString appendAttributedString:mutAttrTextViewString];
NSMutableAttributedString * finalAttributedStr=[[NSMutableAttributedString alloc] initWithAttributedString:mutAttrTextViewSelectedString];
//setting it to the textView
[_tTextView setAttributedText:finalAttributedStr];
Use NSAttributedString
An NSAttributedString object manages character strings and associated sets of attributes (for example, font and kerning) that apply to individual characters or ranges of characters in the string. An association of characters and their attributes is called an attributed string. The cluster’s two public classes, NSAttributedString and NSMutableAttributedString, declare the programmatic interface for read-only attributed strings and modifiable attributed strings, respectively.
NSAttributedString
When you create your attributed string, then just set it to your textView:
self.textView.attributedText = myAttributedString;
Is it possible to format a section of text in a string within the actual code of xcode to be displayed in a single label? For instance make a specific word bold while leaving the rest normal.
Or do I have to use separate strings with different labels with the specific formatting already determined?
Use attributed text. Example below bolds the word posted By but not the name
NSString *format = NSLocalizedStringFromTable(#"Posted By: %#", #"Details Screen", #"posted by %#");
NSString *text = [NSString stringWithFormat:format, name];
const CGFloat fontSize = 14.0;
UIFont *boldFont = [UIFont fontWithName:#"HelveticaNeue-Bold" size:fontSize];
UIFont *regularFont = [UIFont fontWithName:#"HelveticaNeue" size:fontSize];
UIColor *foregroundColor = [UIColor colorWithWhite:(51.0/255.0) alpha:1.0];
// Create the attributes
NSDictionary *attrs = #{NSFontAttributeName: boldFont,
NSForegroundColorAttributeName: foregroundColor};
NSDictionary *subAttrs = #{NSFontAttributeName: regularFont};
const NSRange range = NSMakeRange(text.length - name.length,name.length); // range of " Posted by: "
// Create the attributed string (text + attributes)
NSMutableAttributedString *attributedText =
[[NSMutableAttributedString alloc] initWithString:text
attributes:attrs];
[attributedText setAttributes:subAttrs range:range];
// Set it in our UILabel and we are done!
[_textLabel setAttributedText:attributedText];
I have a string ... Share Pictures .I want to show the Share in different color.I used NSMutableAttributedString to change the color of that part of the string.But when I am setting the cell.textLabel.text using the following string it doesn't work.Any other way to do this?
This way it doesn't work.
NSMutableAttributedString *string3 = [[NSMutableAttributedString alloc]initWithString:#"Share pictures "];
[string3 addAttribute:NSForegroundColorAttributeName value:[UIColor orangeColor] range:NSMakeRange(0, 4)];
NSString *tempStr3 = #"with your friends.";
NSString *finalString3 = [NSString stringWithFormat:#"%#%#" , string3, tempStr3];
[menuTextArray addObject:finalString3];
And in table view datasource method.
cell.textLabel.text = [menuTextArray objectAtIndex:indexPath.row];
You need to add only NSMutableAttributedString into your menuTextArray:
NSMutableAttributedString *yourString = [[NSMutableAttributedString alloc]initWithString:#"Share pictures with your friends"];
[yourString addAttribute:NSForegroundColorAttributeName value:[UIColor orangeColor] range:NSMakeRange(0, 4)];
[menuTextArray addObject:yourString];
then set attributedText
cell.textLabel.attributedText = [menuTextArray objectAtIndex:indexPath.row];
Use attributedText in place of text
cell.textLabel.attributedText = [menuTextArray objectAtIndex:indexPath.row];
Hope this code helps you.....
NSMutableAttributedString *string3 = [[NSMutableAttributedString alloc]initWithString:#"Share pictures with your friends"];
[string3 addAttribute:NSForegroundColorAttributeName value:[UIColor orangeColor] range:NSMakeRange(0, 5)];
[menuTextArray addObject:string3];
[cell.textLabel setAttributedText:string3];
I have to show a text paragraph that contains few words in bold font. ex.
If I use different labels then on changing the orientation it does not resize properly.
Can anyone tell me what can the best way to do it.
You can use an UITextView using NSAttributedString (have a look to the apple doc)
And you have an explanation of how to use it here.
You can find the range of your word and change the font or the color or whatever using :
- (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 value:[UIColor redColor] range:range];
}
}
[self.text setAttributedText:string];
}
You have to use a NSAttributedString and assign it to the UITextField, this is an example:
UIFont *boldFont = [UIFont boldSystemFontOfSize:fontSize];
UIFont *regularFont = [UIFont systemFontOfSize:fontSize];
NSMutableAttributedString *myAttributedString = [[NSMutableAttributedString alloc] initWithString:yourString];
[myAttributedString addAttribute:NSFontAttributeName
value:boldFont
range:NSMakeRange(0, 2)];
[myAttributedString addAttribute:NSFontAttributeName
value:regularFont
range:NSMakeRange(3, 5)];
[self.description setAttributedText:myAttributedString];
Find all the doc here:
NSAttributedString
For your case, you can use a webView and load it with your string:
[webView loadHTMLString:[NSString stringWithFormat:#"<html><body style=\"background-color: transparent;\">This is <b><i>Test</b></i> dummy text ..</body></html>"] baseURL:nil];
