ios - 如何在ios中发送多个参数？

Question

如何发送json格式的参数？

以下是我的输入参数:

[
    {
        "LoginID":151,
        "UserID":0,
        "SubUserID":0,
        "WorkGroupID":92,
        "WorksFor":"Doctor",
        "UserWorkGroup":0
    },
    {
        "SortingName":"",
        "Searching":true,
        "SortingOrder":"Desc",
        "RecordsCount":10,
        "PageIndex":0
    }
]

之前我发送的参数如下:

[getProfileServices sendSynchronousPostRequestWithStringForAction:getProfileURL andParameters:[[NSDictionary alloc] initWithObjectsAndKeys:@"55",@"LoginID",@"0",@"UserID",@"0",@"SubUserID",@"90",@"WorkGroupID",@"Doctor",@"WorksFor",@"0",@"UserWorkGroup",nil] andRequestType:@"POST"];

如何像这样发送，但现在我需要添加上面提到的更多输入？

只需使用以下代码..

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

NSMutableDictionary * myData = [[NSMutableDictionary alloc]init];
[myData setValue:@"151" forKey:@"LoginID"];
[myData setValue:@"0" forKey:@"UserID"];
[myData setValue:@"0" forKey:@"SubUserID"];
[myData setValue:@"92" forKey:@"WorkGroupID"];
[myData setValue:@"Doctor" forKey:@"WorksFor"];
[myData setValue:@"0" forKey:@"UserWorkGroup"];

[myArray addObject:myData];

myData = [[NSMutableDictionary alloc]init];
[myData setValue:@"," forKey:@"SortingName"];
[myData setValue:@"1" forKey:@"Searching"];
[myData setValue:@"Desc" forKey:@"SortingOrder"];
[myData setValue:@"10" forKey:@"RecordsCount"];
[myData setValue:@"0" forKey:@"PageIndex"];
[myArray addObject:myData];

NSData *jsonData2 = [NSJSONSerialization dataWithJSONObject:myArray options:NSJSONWritingPrettyPrinted error:nil];
NSString *jsonString = [[NSString alloc] initWithData:jsonData2 encoding:NSUTF8StringEncoding];
NSLog(@"Your final jsonData as string:\n%@", jsonString);

如果你想将这个数据发送到服务器，那么你可以使用这个代码:

NSData *dataToSend = [NSJSONSerialization dataWithJSONObject:myArray options:0 error:nil];

[getProfileServices sendSynchronousPostRequestWithStringForAction:getProfileURL andParameters:[[NSDictionary alloc] initWithObjectsAndKeys:dataToSend] andRequestType:@"POST"];
