我正在尝试对我的记分牌进行排序，但记分牌是按名称排序的，但我想按分数排序，即（从高到低）分数请帮助解决这个问题。我将玩家姓名和分数详细信息存储在一个标签中。
请帮助我提前谢谢

我想表现得像

在这里，您将字符串（包含名称和分数）添加到数组中。相反，使用名称 (NSString*) 和分数 (NSNumber*) 成员创建模型类并将它们添加到数组中。

对于排序，

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;
}];
