洗牌的隨機化

我創建了我導入所有我的8個圖像的randomization_array ....
我創建了8個圖像的數據的plist（NSDictionary的）

然後，

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

[randomization_array addObjectsFromArray:array]; 
[randomization_array addObjectsFromArray:array]; 

NSMutableArray *shuffled_array = [[NSMutableArray alloc] initWithArray:randomization_array]; 

for(int x=0;x<[randomization_array count]/2;x++) 
{ 
    int random = arc4random_uniform([randomization_array count]/2); 

    int destination = random *2; 

    NSDictionary *origin_dict = [randomization_array objectAtIndex:x]; 
    NSDictionary *destionation_dict= [randomization_array objectAtIndex:destination]; 

    [shuffled_array insertObject:origin_dict atIndex:destination]; 
    [shuffled_array insertObject:destionation_dict atIndex:x];    
}
