iphone - 如何在iPhone中对NSMutableArray值Aa-Zz进行排序？

我正在尝试在iPhone应用程序中按Aa-Zz格式对NSMutablArray值进行排序。我在项目中使用了以下代码。

for (id key in [dictionary allKeys])
        {
            id value = [dictionary valueForKey:key];
            [duplicateArray addObject:value];
            [value release];
            value =nil;
            NSSortDescriptor *sortdis = [[[NSSortDescriptor alloc] initWithKey:@"Name" ascending:YES] autorelease];
            NSArray *discriptor = [NSArray arrayWithObjects:sortdis,nil];
            mutableArray = [[duplicateArray sortedArrayUsingDescriptors:discriptor]retain];
        }
        NSLog(@"mutableArray : %@", mutableArray);
[mutableArray sortUsingSelector:@selector(caseInsensitiveCompare:)];

应用程序因以下错误日志而崩溃：[__NSArrayI sortUsingSelector:]: unrecognized selector sent to instance.

但是，我已经搜索并找到了崩溃的原因。我的mutableArray值是这样的，

(
        {
        Id = 00001;
        Name = "ABCD";
    },
        {
        Id = 00002;
        Name = "BCDE";
    },
        {
        Id = 00003;
        Name = "ZXYS";
    },
        {
        Id = 00004;
        Name = "abcd";
    },
        {
        Id = 00009;
        Name = "bcde";
    },
)

我想对这个数组值进行排序，例如ABCD，abcd，BCDE，bcde，ZXYs。
谁能帮忙解决这个问题。

最佳答案

戈皮纳斯。请在您的项目中使用此更新的代码。

    for (id key in [dictionary allKeys])
    {
        id value = [dictionary valueForKey:key];
        [duplicateArray addObject:value];
        [value release];
        value =nil;
        NSSortDescriptor *sortdis = [[[NSSortDescriptor alloc] initWithKey:@"Name" ascending:YES selector:@selector(localizedCaseInsensitiveCompare:)]autorelease];
        NSArray *discriptor = [NSArray arrayWithObjects:sortdis,nil];
        mutableArray = [[duplicateArray sortedArrayUsingDescriptors:discriptor]retain];
    }
    NSLog(@"mutableArray : %@", mutableArray);

希望对您有帮助。谢谢。
