Question

这是我的代码

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 *dataToSend = [NSJSONSerialization dataWithJSONObject:myArray options:0 error:nil];
NSString *jsonString = [[NSString alloc] initWithData:dataToSend encoding:NSUTF8StringEncoding];

[getProfileServices sendSynchronousPostRequestWithStringForAction:getProfileURL andParameters:[[NSDictionary alloc]initWithObjectsAndKeys:jsonString ,nil]andRequestType:@"POST"];

当我运行时遇到此错误

NSInvalidArgumentException，原因：-[__NSPlaceholderDictionary initWithObjectsAndKeys:]:每对的第二个对象必须是非零的。或者，您是否忘记了终止参数列表？＆＃39; ***首先抛出调用堆栈：

Answer 1

在NSDictionary或NSMutableDictionary设置字符串值和字符串键。例：以下示例格式正确，

[myData setValue：@“1”forKey：@“Searching”];

不发送nil值和nil键。

不要在字典
中发送，内部值

你的错误在下面给出

[myData setValue:@"," forKey:@"SortingName"];

以上问题是“，”

更改代码如下，

[myData setValue:@"String Value" forKey:@"SortingName"];

或

请更改以下代码，

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

希望它有用

每对的第二个对象必须是非零的。或者，您是否忘记了终止参数列表？＆＃39;
