Cocoa NSString爆炸

Question

我有一个NSString : @"1a,1b,1c,1d,5c". 我想将这个NSString分成NSMutableArray,但我不知道如何.我认为这很简单,但我找不到它(也许是因为我的英语不够好,无法找到一个好的描述来搜索).

此致,渡渡鸟

Answer 1

NSString *_stringToSplit = @"1a,1b,1c,1d,5c";
NSArray *_splitItems = [_stringToSplit componentsSeparatedByString:@","];
NSMutableArray *_mutableSplitItems = [NSMutableArray arrayWithCapacity:[_splitItems count]]; 
[_mutableSplitItems addObjectsFromArray:_splitItems];

Answer 2

[NSMutableArray arrayWithArray:[string componentsSeparatedByString:@","]];
