iOS - UITableViewCell make text bold
提问by Vanessa
I have a string:
我有一个字符串：
NSString *userInfo = @"James Johnson @james";
What i want to do is bold James Johnsonand keep @jamesnormal font.
我想要做的是加粗James Johnson并保持@james正常字体。
So what I have tried is using NSAttributedStringbut somewhere I'm doing something wrong in order to complete the process.
所以我尝试过的是使用NSAttributedString但在某处我做错了为了完成这个过程。
This is what I have tried:
这是我尝试过的：
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?
即使我走错了方向，有没有办法让我完成这项工作？
What's not working
什么不起作用
For some reason, the characters from range 0 - 3 is not being a light font...instead the entire cell.textLabel.textis bold somehow and is not font size 14 which i had specified in the UIFont.
出于某种原因，0 - 3 范围内的字符不是浅色字体……而是整个cell.textLabel.text字体以某种方式加粗，而不是我在 UIFont 中指定的字体大小 14。

Your last part of it is wrong. You must create your NSAttributedStringand finally trash the formatting by using
你的最后一部分是错误的。您必须NSAttributedString使用
NSString *str = [string string];
As NSStringdoesn't know anything about formatting you have to use the NSAttributedStringto assign it to the cell's textLabel:
由于NSString对格式一无所知，您必须使用 将NSAttributedString其分配给单元格的textLabel：
cell.textLabel.attributedText = string;

You should set attributedStringto attributedtext
你应该设置attributedString为attributed文本
Comment these lines
注释这些行
//NSString *str = [string string];
//cell.textLabel.text = str;
And write this
并写下这个
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.
UILabel 有一个属性attributedText。您应该使用属性字符串分配此属性，而不是使用文本属性。

Make changes in you code as follows :
对您的代码进行如下更改：
- 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".
- 您将需要报告 NSMutableAttributedString 中的所有字符，因此在添加属性时在范围内指定它们。
- 提供正确的属性名称，否则这里会有一个例外，在这种情况下，您应该使用“NSFontAttribteName”代替“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;
