代碼如何將單個數組分成多個數組？

Question

可能重複：
How is the code for separation of single array into two arrays?

大家好我得到如下回應到單個陣列時，我使用的JSON從我需要解析URL，但在這裏，我必須分配單個陣列響應成三個陣列集合，其中一個集合將具有TB3257，TB3259，TB3261，TB3263，TB3257，TB3260，並且第二陣列集合將具有TB3258，TB3260，TB3262，TB3259，TB3258和TB3261，並且第三陣列集合將具有TB3258。那麼在iPhone中將單個數組劃分爲三個數組集合的代碼如何？

(
    " TB3257 TB3258", 
    " TB3259 TB3260", 
    " TB3261 TB3262", 
    " TB3263 TB3259", 
    " TB3257 TB3258 TB3258", 
    " TB3260 TB3261" 
)

我只是想下面的代碼：

NSArray *yourArray = [NSArray arrayWithObjects:@"TB3257 TB3258", @"TB3259 TB3260", @"TB3261 TB3262", @"TB3263 TB3259", @"TB3257 TB3258 TB3258", @"TB3260 TB3261", nil]; 
NSMutableArray *firstArray = [NSMutableArray array]; 
NSMutableArray *secondArray = [NSMutableArray array]; 
NSMutableArray *thirdArray = [NSMutableArray array]; 
for (int i = 0; i < [yourArray count]; i++) { 
    NSArray *tempArray = [[yourArray objectAtIndex:i]componentsSeparatedByString:@" "]; 
    [firstArray addObject:[tempArray objectAtIndex:0]]; 
    [secondArray addObject:[tempArray objectAtIndex:1]]; 
    if ([tempArray count] == 3) { 
     [thirdArray addObject:[tempArray objectAtIndex:2]]; 
    } 
} 
NSLog(@"yourArray: %@\nfirst: %@\nsecond: %@\nthird: %@", yourArray, firstArray, secondArray, thirdArray); 

產量爲：

yourArray: (
    "TB3257 TB3258", 
    "TB3259 TB3260", 
    "TB3261 TB3262", 
    "TB3263 TB3259", 
    "TB3257 TB3258 TB3258", 
    "TB3260 TB3261" 
) 
first: (
    TB3257, 
    TB3259, 
    TB3261, 
    TB3263, 
    TB3257, 
    TB3260 
) 
second: (
    TB3258, 
    TB3260, 
    TB3262, 
    TB3259, 
    TB3258, 
    TB3261 
) 
third: (
    TB3258 
) 

希望它可以幫助
