1.利用NSMutableAttributedString修改字符串的顏色
+ (NSMutableAttributedString *)attributedStringWithTitle:(NSString *)fitstTitle SecondTitle:(NSString *)secondTitle firstColor:(UIColor *)firstColor secondColor:(UIColor *)secondColor
{
NSMutableAttributedString *str = [[NSMutableAttributedString alloc] initWithString:[NSString stringWithFormat:@"%@%@",fitstTitle,secondTitle]];
[str addAttribute:NSForegroundColorAttributeName value:firstColor range:NSMakeRange(0,fitstTitle.length)];
[str addAttribute:NSForegroundColorAttributeName value:secondColor range:NSMakeRange(fitstTitle.length,secondTitle.length)];
return str;
}
2.利用NSMutableAttributedString修改字符串的字體
+ (NSMutableAttributedString *)attributedStringWithTitle:(NSString *)fitstTitle SecondTitle:(NSString *)secondTitle firstFont:(UIFont *)firstFont secondfont:(UIFont *)secondFont
{
NSMutableAttributedString *str = [[NSMutableAttributedString alloc] initWithString:[NSString stringWithFormat:@"%@%@",fitstTitle,secondTitle]];
[str addAttribute:NSFontAttributeName value:firstFont range:NSMakeRange(0,fitstTitle.length)];
[str addAttribute:NSFontAttributeName value:secondFont range:NSMakeRange(fitstTitle.length,secondTitle.length)];
[str addAttribute:NSForegroundColorAttributeName value:ZFColor_ox(0x333333) range:NSMakeRange(0,fitstTitle.length)];
[str addAttribute:NSForegroundColorAttributeName value:ZFColor_ox(0x333333) range:NSMakeRange(fitstTitle.length,secondTitle.length)];
NSMutableParagraphStyle *paragraphStyle = [[NSMutableParagraphStyle alloc] init];
[paragraphStyle setLineSpacing:[ZFUtility getAllViewHeight:20]];
[str addAttribute:NSParagraphStyleAttributeName value:paragraphStyle range:NSMakeRange(0, [fitstTitle length])];
return str;
}
3. 字符串隔三位加特殊符號
/**
隔三位加符號
@param numbers <#numbers description#>
*/
+ (NSString *)hanleNums:(NSString *)numbers{
NSString *str = [numbers substringWithRange:NSMakeRange(numbers.length%3, numbers.length-numbers.length%3)];
NSString *strs = [numbers substringWithRange:NSMakeRange(0, numbers.length%3)];
for (int i =0; i < str.length; i =i+3) {
NSString *sss = [str substringWithRange:NSMakeRange(i, 3)];
strs = [strs stringByAppendingString:[NSString stringWithFormat:@",%@",sss]];
}
if ([[strs substringWithRange:NSMakeRange(0, 1)] isEqualToString:@","]) {
strs = [strs substringWithRange:NSMakeRange(1, strs.length-1)];
}
return strs;
}
