ios - 将 NSString 转换为 NSDIctionary

Question

我有一个字符串 ------ NSString abc = @"apple:87,banana:32,grapes:54";

我需要这样的输出

{
    name = "apple";
    value = "87";
},
{
    name = "banana";
    value = "32";
},
{
    name = "grapes";
    value = "54";
}

我试过:

NSArray* itemList = [abc componentsSeparatedByString:@","]; 
NSMutableDictionary* dict = [NSMutableDictionary dictionary];

for (NSString* item in itemList) {
    NSArray* subItemList = [item componentsSeparatedByString:@":"];

    if (subItemList.count > 0) {
       [dict setObject:[subItemList objectAtIndex:1] forKey:[subItemList objectAtIndex:0]];
    }
}

NSLog(@"%@", dict); 

输出是——

{ 
    apple = 87;
    banana = 32;
    grapes = 54;
}

但我不想要这个输出

Answer 1

想要的输出是 NSDictionary 的 NSArray。

所以:

NSArray* itemList = [abc componentsSeparatedByString:@","]; 
NSMutableArray *finalArray = [[NSMutableArray alloc] init];
for (NSString *aString in itemList)
{
    NSArray* subItem = [aString componentsSeparatedByString:@":"];
    NSDictionary *dict = @{@"name":[subItem objectAtIndex:0], 
                           @"value":[subItem objectAtIndex:1]};
    [finalArray addObject:dict];
}

我没有使用 if ([subItem count] > 0)，只是想保持您错过的逻辑并阐明算法。

我没有测试代码，但应该可以。 (或者可能是一些容易纠正的编译器错误)。
