        [arrone release];
        [Dictmain release];
    }
}
[arrAll retain];
NSLog(@"Array before sorting:%@",arrAll);

我希望 arrAll 根据 Views、CommentCount、Likes、Favorites 进行排序，我希望结果相同，因为任何机构都可以帮助我解决这个问题。请抱歉格式化

下面是从NSArray 类参考中选择的可能的数组排序函数：

– sortedArrayHint
– sortedArrayUsingFunction:context:
– sortedArrayUsingFunction:context:hint:
– sortedArrayUsingDescriptors:
– sortedArrayUsingSelector:
– sortedArrayUsingComparator:
– sortedArrayWithOptions:usingComparator:

这只是一种数组排序方法。你必须使用 NSSortDescriptor

NSSortDescriptor *lastNameDescriptor = [[NSSortDescriptor alloc] initWithKey:@"CATALOG_NO" ascending:YES];
[nameArray sortUsingDescriptors:[NSArray arrayWithObject:lastNameDescriptor]];

其中 initWithKey 您必须在其中使用您的键值 您必须对哪个值数组进行排序和名称 Array 是您的数组，其中包含您的数组

NSSortDescriptor *sortDesc = [[NSSortDescriptor alloc] initWithKey:sortString  ascending:NO comparator:^NSComparisonResult(id firstObject, id secondObject)
            {
                return [((NSString *)firstObject) compare:((NSString *)secondObject) options:NSNumericSearch];
            }];

            arrContent = [arrContentOriginal sortedArrayUsingDescriptors:[NSArray arrayWithObject:sortDesc]];

找到这个解决方案
