Question

我正在进行Json解析，因为我需要解析“TStatus”键来显示表格。

在该TStatus键中，值为3types。它们是100001,100002,100003。

我只想要100001值......如何获取这些值并将其存储在数组中。

NSMutableArray *array = [arrayOfoccupiedTables valueForKey:@"TStatus"];

回复是

 {
        Msg = "";
        TStatus = 100003;
        "Table_Id" = 446;
    },
        {
        Msg = "";
        TStatus = 100001;
        "Table_Id" = 447;
    },
        {
        Msg = "";
        TStatus = 100001;
        "Table_Id" = 448;
    },
        {
        Msg = "";
        TStatus = 100001;
        "Table_Id" = 449;
    },
        {
        Msg = "";
        TStatus = 100001;
        "Table_Id" = 450;
    },
        {

        TStatus = 100001;

Plz帮助我解决这些问题......提前致谢

Answer 1

您必须使用 NSPredicate

过滤数组

NSPredicate *predicate = [NSPredicate predicateWithFormat:@"TStatus == 100001"];

NSArray *filtered = ["Your Array" filteredArrayUsingPredicate:predicate];

在过滤后的数组中，您可以获得 Tstatus = 100001;

的值

Answer 2

你有一个这个所有数据的数组，例如数组名称是arrList，当你想获得TStatus为100001的整个数据然后用下面的代码过滤时，只使用下面的代码。

NSMutableArray *arrTStatus = [[NSMutableArray alloc]init];
 for (int i =0; i<[arrList count]; i++) 
 {
     if ([[[arrList objectAtIndex:i]valueForKey:@"TStatus"] isEqualToString:@"100001"] ) 
     {
          [arrTStatus addObject:[arrList objectAtIndex:i]];   
     }
 }

Answer 3

希望这会有所帮助

[allObject filteredArrayUsingPredicate:[NSPredicate predicateWithFormat:@"TStatus = 100001"]];

Answer 4

试试这个

for (NSDictionary *status in statuses) {

NSString *Tstatus = [status objectForKey:@"TStatus"]
if([Tstatus isEqualToString:@"100001"){
//Do your code here
}
}
