Here you are adding the string (containing name and score) to the array. Instead, create a model class with the name (NSString*) and score (NSNumber*) members and add them to the array.

在这里,您将字符串(包含名称和分数)添加到数组中。而是创建一个名为(NSString *)和score(NSNumber *)成员的模型类,并将它们添加到数组中。

For sorting,

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;
}];
