在iOS中提取字典的NSArray

Question

我有一个如下的响应数据。我有一个由字典填充的数组，我需要对多维数组的每个索引中的最后两个值进行排序。

这是我的数组：

数组列表状态

(

    {

    "Applicant_FirstName" = "";
    "Applicant_LastName" = "";
    "Application_ID" = test;
    "Application_Status" = "";
},
    {
    "Applicant_FirstName" = John;
    "Applicant_LastName" = Doe;
    "Application_ID" = 0002;
    "Application_Status" = Recertify;
}
)

这是我的代码：

- (NSArray *)subItems

{

NSMutableArray *items = [[NSMutableArray alloc] init];

for (int ar = 0; ar < arrayListstatus.count; ar++)

{
    NSArray *thirdarray=[arrayListstatus objectAtIndex:ar] ;


    NSLog(@"thirdarray %@",third array);


    [items addObject:thirdarray];

}

NSLog(@"itemss %@",items);

return items;


}

Answer 1

我认为这应该可以解决问题：

- (NSArray *)subItems

{

NSMutableArray *items = [[NSMutableArray alloc] init];

for (int ar = 0; ar < arrayListstatus.count; ar++)

{

   NSArray *thirdarray= [arrayListstatus objectAtIndex:ar] ;
NSMutableDictionary *tmpDict = [NSMutableDictionary alloc] init];
[tmpDict setObject:[thirdarray objectAtIndex:2] forKey:@"Application_ID"];
 [tmpDict setObject:[thirdarray objectAtIndex:3] forKey:@"Application_Status"];

[items addObject:tmpDict];

    [items addObject:tmpDict];

}

NSSortDescriptor *sortDescriptor;
sortDescriptor =  [NSSortDescriptor sortDescriptorWithKey:"Application_Status" ascending:YES], nil]];
NSArray *sortDescriptors = [NSArray arrayWithObject:sortDescriptor];
NSArray *sortedArray = [items sortedArrayUsingDescriptors:sortDescriptors];




NSLog(@"itemss %@",items);

return items;


}
