如何从NSMutableArray获取NSMutableArray

Question

我有NSMutableArray如下.

(
        {
        ClientId = "17";
        FileURL = "http://www.xxx.com/b0a89db3-482b-464e-81ae-78439527c702.jpg";
    },
        {
        ClientId = "56";
        FileURL = "http://www.xxx.com/f7633371-b726-4332-9b26-a98a2fed991d.jpg";
    }
)

我想要的是NSMutableArray,它看起来类似于下面.

NSMutableArray *image_array = 
    [NSMutableArray arrayWithObjects:
    @"http://www.xxx.com/b0a89db3-482b-464e-81ae-78439527c702.jpg", 
    @"http://www.xxx.com/f7633371-b726-4332-9b26-a98a2fed991d.jpg", 
    nil];

知道怎么做吗？

我试过了

NSArray *filtered = [feeds filteredArrayUsingPredicate:[NSPredicate predicateWithFormat:@"(FileURL CONTAINS[cd] %@)", @"%http%"]];
NSLog(@"filter====%@", filtered);

但我没有得到任何东西.数据为空白.

实际上我有以下格式的主阵列.

(
        {
        ClientId = "17\n    ";
        FileURL = "http://www.xxx.com/b0a89db3-482b-464e-81ae-78439527c702.jpg\n\n";
    },
        {
        ClientId = "56\n    ";
        FileURL = "http://www.xxx.com/f7633371-b726-4332-9b26-a98a2fed991d.jpg\n\n";
    }
)

知道如何\n在创建新数组时删除那些和空格？

您可以使用KVC来获取数组:

[[array valueForKey:@"FileURL"] mutableCopy];
