每對中的第二個對象必須是非零。或者，你忘了沒有終止你的參數列表？'

Question

這裏是我的代碼

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"]; 

當我運行此我得到這個錯誤

NSInvalidArgumentException，原因是：-[__NSPlaceholderDictionary initWithObjectsAndKeys:]:每對第二個對象必須是非零。或者，你忘了沒有終止你的參數列表？' ***第一擲調用堆棧：

Answer 1

在NSDictionary或NSMutableDictionary組字符串值和字符串鍵。例如： 下面的例子是正確的格式，

[myData setValue：@「1」forKey：@「Searching」];

不發送零值和零密鑰。

不發送，內在價值在字典下面

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

上述問題是

你的錯誤給出 「」

變化代碼以下，

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

或

請修改下面的代碼，

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

希望它有幫助
