ios - 如何在保留分隔符的同时拆分 NSString

我正在使用以下内容以“，”分隔字符串:

NSString * receivedString = @"component1,component3,,component6";
NSArray * arrayOfSubstrings = [receivedString componentsSeparatedByString","];

但是我想保留“，”作为单独的组件并获取以下数组:

[0] "component1"
[1] ","
[2] "component2"
[4] ","
[5] ","
[6] "component6"

而不是:

[0] "component1"
[1] "component2"
[2] "component6"

基本上，“，”也是我要分析的元素。

知道如何在不重新发明轮子的情况下做到这一点吗？

           withSeparatorNSString *)separator
{
    NSArray *elements = [string componentsSeparatedByString:separator];
    NSMutableArray *arr = [NSMutableArray new];
    for (NSUInteger i = 0; i < [elements counts]; i++) {
        NSString *element = elements[i];
        if ([element length] > 0)
            [arr addObject:element];
        if (i != [elements count] - 1)
            [arr addObject:separator];
    }
    return arr;
}
