Objective c 对可变词典进行排序

任何正确方向的指点都将受到感激

我有以下格式的NSD词典：

{
3 = "special-collection-procedures-see-notes|";
13 = "<p>None Given</p>";
16 = "";
6 = "<p>Arrange for sample to be separated at an interim site and subsequently transport frozen to lab, if it cannot reach lab within one hour.</p>";
9 = "<p>Stored in laboratory at -20C</p>";
12 = "<p>None</p>";
2 = "images/tubes/lightblue_tube_large.png";
15 = "";
5 = "";
8 = "Up to 28 days";
11 = "<p>Some indications: Hereditary Angioedema</p><p>Sample type is citrated plasma though plain serum can also be used.</p>";
1 = " Functional C1 esterase inhibitor";
14 = "|";
4 = "5-10 mL";
7 = "<p>Frozen if unable to deliver within one hour</p>";
10 = "<p>expressed as a percentage of a control serum with 75% -125% being classed as normal.</p>";

等等

我有一段代码：

NSArray *myArray; 

myArray = [[valuesDictionary allKeys] sortedArrayUsingComparator: ^(id obj1, id obj2) {

    if ([obj1 integerValue] > [obj2 integerValue]) {

        return (NSComparisonResult)NSOrderedDescending;
    }
    if ([obj1 integerValue] < [obj2 integerValue]) {

        return (NSComparisonResult)NSOrderedAscending;
    }

    return (NSComparisonResult)NSOrderedSame;
}];

NSMutableDictionary *sortedDisplay = [[NSMutableDictionary alloc] init];

for (id object in myArray) {
    // do something with object
    [sortedDisplay setObject:[valuesDictionary objectForKey:object] forKey:object];

}

NSArray*myArray；
myArray=[[valuesDictionary allKeys]使用比较器排序数组：^（id obj1，id obj2）{
如果（[obj1整型值]>[obj2整型值]）{
返回（NSComparisonResult）或撤销；
}
如果（[obj1整型值]<[obj2整型值]）{
返回（NSComparisonResult）或删除；
}
返回（NSComparisonResult）命令名；
}];
NSMutableDictionary*sortedDisplay=[[NSMutableDictionary alloc]init]；
for（myArray中的id对象）{
//用物体做某事
[sortedDisplay setObject:[valuesDictionary objectForKey:object]forKey:object]；
}

这给了我一个排序的myArray： 1. 2. 3. 4. 5. 6. 7. 8. 9, 10, 11, 12, 13, 14, 15, 十六,

但最终的“排序”可变字典没有排序，即

sortedDisplay的打印说明：

{
13 = "<p>None Given</p>";
12 = "<p>None</p>";
11 = "<p>Some indications: Hereditary Angioedema</p><p>Sample type is citrated plasma though plain serum can also be used.</p>";
7 = "<p>Frozen if unable to deliver within one hour</p>";
6 = "<p>Arrange for sample to be separated at an interim site and subsequently transport frozen to lab, if it cannot reach lab within one hour.</p>";
2 = "images/tubes/lightblue_tube_large.png";
1 = " Functional C1 esterase inhibitor";
14 = "|";
15 = "";
10 = "<p>expressed as a percentage of a control serum with 75% -125% being classed as normal.</p>";
9 = "<p>Stored in laboratory at -20C</p>";
8 = "Up to 28 days";
5 = "";
4 = "5-10 mL";
3 = "special-collection-procedures-see-notes|";
16 = "";

{
13=“未给出任何值”
”；
12=“None
”；
11=“一些适应症：遗传性血管性水肿
样本类型为柠檬酸血浆，但也可使用普通血清。
”；
7=“如果无法在一小时内交付，则冻结”
”；
6=“如果样品在一小时内无法到达实验室，则安排在临时现场分离样品，并随后将其运送至实验室。
”；
2=“images/tubes/lightblue\u tube\u large.png”；
1=“功能性C1酯酶抑制剂”；
14 = "|";
15 = "";
10=“表示为对照血清的百分比，75%-125%被归类为正常。
”；
9=“储存在-20℃的实验室中”
”；
8=“最多28天”；
5 = "";
4=“5-10毫升”；
3=“特殊收款程序见附注|”；
16 = "";

}

正在尝试对字典进行排序。

Tommyo是对的，您无法对

NSDictionary

进行排序。其目的是在性能方面高效地存储和检索数据

---

如果需要按特定顺序存储数据，请对键使用

NSArray

（正如您已经在做的那样），并在需要时使用它访问字典值。

您将要创建一个排序数组：

    NSArray *sortedKeys = [dictionary keysSortedByValueWithOptions:NSNumericSearch usingComparator:^NSComparisonResult(NSString *a, NSString *b){
        return [a compare:b];
    }];
    //Now you have an array of sorted keys


    NSMutableArray *sortedArray = [[NSMutableArray alloc] initWithCapacity:sortedKeys.count];
    for (NSString *key in sortedKeys){
        NSDictionary *dict = [NSDictionary dictionaryWithObject:[dictionary valueForKey:key] forKey:key];
        [sortedArray addObject:dict];
    }
    //Now you have a sortedArray of key-value pairs
