如何按整數排序數組

Question

我想排序我的計分板，但計分板按名稱排序，但我想按分數排序（即從高到低）分數有助於解決this.i存儲的玩家名稱並在一個標籤中評分詳情。
請幫我 在此先感謝

這裏您要添加字符串（包含名字和分數）給數組。相反，使用名稱（NSString *）創建一個模型類並將其分數（NSNumber *）成員並將它們添加到數組中。

的分類，

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; 
}];
