有没有办法只加粗字符串的一部分？例如:

近似距离:120米远

谢谢!

NSString *str = @" My name is Mike, I live in California and I work in Texas. Weather in California is nice but in Texas is too hot...";

我怎样才能遍历这个NSString并为每次出现的"California"获取NSRange,我想要NSRange,因为我想在NSAttributed字符串中更改它的颜色.

 NSRange range = NSMakeRange(0,  _stringLength);
 while(range.location != NSNotFound)
 {
    range = [[attString string] rangeOfString: @"California" options:0 range:range];


    if(range.location != NSNotFound)
    {

        range = NSMakeRange(range.location + range.length,  _stringLength - (range.location + range.length));


        [attString addAttribute:NSForegroundColorAttributeName value:_green range:range];
    }
}
