objective-c - 条件が使用する JSON の解析

Question

他に何もなくなるまでJSONを解析する方法を知りたいですか?

ここに私のコードがありますが、私の条件には何か他のものが必要です...

 for (int i = 0; i != 7; i++)
        {
            Boxes *boxes = [NSEntityDescription insertNewObjectForEntityForName:@"Boxes" inManagedObjectContext:context];
            boxes.name =   [[[json valueForKey:@"boxesDetail"] objectAtIndex:i] valueForKey:@"name"] ;
            boxes.sexe =   [[[json valueForKey:@"boxesDetail"] objectAtIndex:i] valueForKey:@"sexe"] ;
            boxes.topic =   [[[json valueForKey:@"boxesDetail"] objectAtIndex:i] valueForKey:@"topic"] ;
            boxes.number = [NSNumber numberWithInt:[[[[json valueForKey:@"boxesDetail"] objectAtIndex:i] valueForKey:@"number"] intValue]];
        }

Answer 1

単純に、boxDetail オブジェクトの数を取得します。

int count = [[json objectForKey:@"boxesDetail"] count];
 for (int i = 0; i < count; i++)
        {
            Boxes *boxes = [NSEntityDescription insertNewObjectForEntityForName:@"Boxes" inManagedObjectContext:context];
            boxes.name =   [[[json valueForKey:@"boxesDetail"] objectAtIndex:i] valueForKey:@"name"] ;
            boxes.sexe =   [[[json valueForKey:@"boxesDetail"] objectAtIndex:i] valueForKey:@"sexe"] ;
            boxes.topic =   [[[json valueForKey:@"boxesDetail"] objectAtIndex:i] valueForKey:@"topic"] ;
            boxes.number = [NSNumber numberWithInt:[[[[json valueForKey:@"boxesDetail"] objectAtIndex:i] valueForKey:@"number"] intValue]];
        }
