konvertieren Wörterbuch in Array nach dem Entfernen von Schlüsselwerten

Question

Ich muss die ersten drei Schlüssel Werte aus jedem Index des Arrays entfernen. Was ich getan habe ist

for (int i=0; i<[normalscoringarray count]; i++)   
    { 

     NSDictionary *dictionary = [normalscoringarray objectAtIndex:i]; 

     NSMutableDictionary *mutableDictionary = [dictionary mutableCopy]; 

     [mutableDictionary removeObjectForKey:@"cn"]; 
     [mutableDictionary removeObjectForKey:@"gdate"]; 
     [mutableDictionary removeObjectForKey:@"gid"]; 

     NSLog(@"mutableDictionary.....%@",mutableDictionary); 

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

     for (id item in mutableDictionary) { 
      [remainingArray setArray:[mutableDictionary objectForKey:item]]; 
     } 
     } 

und es nicht geben remainingArray in dieser Reihenfolge ich will, mehr über sie alle Schlüssel entfernt.

die Art, wie ich will

normalscoringarray....(
    id = 1, 
    p1nets = "3,3,4,4,2,2,2,4,3,3,4,2,5,3,5,4,3,4||27||33||60",

Answer 1

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

for (int i=0; i<[normalscoringarray count]; i++)   
{ 
    NSMutableDictionary *mutableDictionary = [[NSMutableDictionary alloc] initWithDictionary:[normalscoringarray objectAtIndex:i]]; //each time alloc and init with contents of normalscoringarray 

    //Remove values for keys 
    [mutableDictionary removeObjectForKey:@"cn"]; 
    [mutableDictionary removeObjectForKey:@"gdate"]; 
    [mutableDictionary removeObjectForKey:@"gid"]; 

    [remainingArray addObject:mutableDictionary]; //add mutableDictionary to remainingArray 

    [mutableDictionary release]; //free mutableDictionary 
} 

//finally print contents of remainingArray 
NSLog(@"normalscoringarray:\n%@",[remainingArray description]); 

Hoffnung Dies würde helfen Ihnen!

Answer 2

for (int i=0; i<[normalscoringarray count]; i++)   
{  
    NSMutableDictionary *dictionary = [NSMutableDictionary dictionaryWithDictionary:[normalscoringarray objectAtIndex:i]]; 


    [dictionary removeObjectForKey:@"cn"]; 
    [dictionary removeObjectForKey:@"gdate"]; 
    [dictionary removeObjectForKey:@"gid"]; 

     [normalscoringarray replaceObjectAtIndex:i withObject:dictionary]; 
}
