単一のUIViewcontrollerのMultipleUIPickerViewの問題IOSアプリケーションの

Question

私はthis.codeのようなUIPickerviewを開発したいと思っています。

データiがdifferantアレイ内にINDIVISUAL SOAP応答を追加し、PickerViewのタグに基づいた割り当てのために、私はthissee referance画像ようDevelopeするコードの上に使用

は、私は、3 PickerViewを有しており、データは石鹸Webサービスから設定されています値のデータが割り当てられますが、問題は最初の石鹸応答がpickerviewで割り当てられているだけです。残りの2つはnullです。間違っている場合は、私に提案してください。

Answer 1

あなたがのviewDidLoadで{

• （無効）のviewDidLoadを[最初のサービスを呼び出します

  [self dropdownshape]; 
  
  [self dropdowncolor]; 
  
  [self dropdownclarity]; 
  

  代わりにその時に3つのWebサービスを呼び出していますスーパービューDidLoad];

  [self dropdownshape];

}

その最初の接続は、（接続）{

resshap = [NSMutableDataデータ]場合は

第二のウェブサービスを呼び出すことができることで確立された後。

[self dropdowncolor];そして、第二の接続は、それはあなた

に役立つだろうチェックリンクの下（接続）{

rescolor = [NSMutableData data]; 

[self dropdownclarity]; 

} 

場合は、第3ウェブサービス

を呼び出すことができるということで設立された

}

- （void）接続：（NSURLConnection *）接続didReceiveResponse：（NSURLResponse *）応答 {

if(connection == connection1) { 

    //Do something with connection 1 

} 

else if(connection == connection2) { 

    //Do something with connection 2  

} 

（接続== connection3）{

//Do something with connection 3 

} 

}

Answer 2

Try 

picker1.delegate=self; 
picker1.tag = 1; 

picker2.delegate=self; 
picker2.tag = 2; 

picker3.delegate=self; 
picker3.tag = 3;
