+(NSMutableAttributedString*)changeTextColorWith:(NSString*)keyStr AndSourceStr:(NSString*)sourceStr
{
NSMutableAttributedString*changeStr = [[NSMutableAttributedStringalloc]initWithString:sourceStr];
if([sourceStrcontainsString:keyStr]) {
NSArray*commpentArr = [sourceStrcomponentsSeparatedByString:keyStr];
NSIntegerlocation =0;
for(inti=0;i < commpentArr.count-1;i++) {
NSString*str = commpentArr[i];
location += (i >0? (str.length+keyStr.length):str.length);
[changeStraddAttribute:NSForegroundColorAttributeNamevalue:[UIColorredColor]range:NSMakeRange(location,keyStr.length)];
}
}
returnchangeStr;
}
这里颜色是变成红色,若想自定义颜色传进参数即可......
