我正在做一个 Json 解析，因为我需要解析“TStatus”键来显示表格。

在该 TStatus 键中，值为 3 种类型。它们是 100001、100002、100003。

我只想要 100001 个值...如何获取这些值并将其存储在数组中。

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

回应是

 {
        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;
    },
        {
        Msg = "";
        TStatus = 100001;
        "Table_Id" = 451;
    },
        {
        Msg = "";
        TStatus = 100001;
        "Table_Id" = 452;
    },
        {

请帮我摆脱这些家伙...在此先感谢

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，您将获得Tstatus = 100001 的值；

您有一个包含所有数据的数组，例如，arrList当您想要获取 TStatus 为 100001 的整个数据时，只需使用下面的代码，然后使用下面的代码过滤即可。

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]];   
     }
 }

尝试这个

for (NSDictionary *status in statuses) {

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

希望这会有所帮助

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