如何在iOS中

Question

使用可變如何使用可變initWithObjectAndkeys，我想通過對無類別項目的環initWithObjectAndkeys，請大家幫忙

如果我使用的NSArray像這樣

data = [saved_result valueForKey:@"data"]; 
     NSLog(@"%@",[data valueForKey:@"category"]); 

     NSArray *myArray = [[NSArray alloc]initWithObjects:data, nil]; 
    for (id tempObject in myArray) { 
     NSLog(@"Single element: %@", tempObject); 

     } 

這裏的內容NSArray類型的變量保存數據，它會幫助你理解代碼。 保存的結果=

(
      { 
      data =   { 
       amount = 10; 
       category = Food; 
       dealid = 28; 
       enddate = "2016-12-31"; 
       retailername = mukesh; 
       startingdate = "2015-01-10"; 
       title = gter; 
      }; 
      msg = "deals found"; 
      status = true; 
     }, 
      { 
      data =   { 
       amount = 10; 
       category = Shopping; 
       dealid = 44; 
       enddate = "2016-12-31"; 
       retailername = divya; 
       startingdate = "2015-01-10"; 
       title = welcome; 
      }; 
      msg = "deals found"; 
      status = true; 
     } 
      )

Answer 1

你保存的結果是NSArray即arrResult，所以我們將loop穿過。

for(NSDictionary *dictObject in arrResult) 
{ 
    //Get Data Dictionary 
    NSDictionary *dictData = [dictObject valueForKey:@"data"]; 
    //Now have data so traverse 
    for (NSString*strkey in dictData) { 
     id value = [dictData objectForKey:strkey]; 
     NSLog(@"id = %@",value); 
    } 
}
