NSMutableArray *arrayRanges = [NSMutableArray array];
//方法一、NSRegularExpression ,这个最快
NSRegularExpression *regex = [NSRegularExpression regularExpressionWithPattern:subString options:0 error:nil];
NSArray *matches = [regex matchesInString:totalString options:0 range:NSMakeRange(0, totalString.length)];
for(NSTextCheckingResult *result in matches){
NSRange matchRange = [result range];
[arrayRanges addObject:[NSNumber valueWithRange:matchRange]];
}
return arrayRanges;
这是我用的，还有别的方法在：http://www.jianshu.com/p/11a57360d261
