如何按整数排序数组

Question

我想排序我的计分板，但计分板按名称排序，但我想按分数排序（即从高到低）分数有助于解决this.i存储的玩家名称并在一个标签中评分详情。
请帮我 在此先感谢

这里您要添加字符串（包含名字和分数）给数组。相反，使用名称（NSString *）创建一个模型类并将其分数（NSNumber *）成员并将它们添加到数组中。

的分类，

NSArray *sortedArray = [yourUnsortedArray sortedArrayUsingComparator: ^(id obj1, id obj2) { 

    if ([[obj1 score] integerValue] > [[obj2 score] integerValue]) { 
     return NSOrderedDescending; 
    } 

    if ([[obj1 score] integerValue] < [[obj2 score] integerValue]) { 
     return NSOrderedAscending; 
    } 
    return NSOrderedSame; 
}];
