ViewDidLoad загрузить 4 изображения

Question

Я пробовал это в моем ViewDidLoad:

NSString *myGrabbedImage = @"myGrabbedImage.png"; 
NSString *myGrabbedImage2 = @"myGrabbedImage2.png"; 
NSString *myGrabbedImage3 = @"myGrabbedImage3.png"; 
NSString *myGrabbedImage4 = @"myGrabbedImage4.png"; 

NSArray *path = NSSearchPathForDirectoriesInDomains(NSDocumentDirectory, NSUserDomainMask, YES); 
NSArray *path2 = NSSearchPathForDirectoriesInDomains(NSDocumentDirectory, NSUserDomainMask, YES); 
NSArray *path3 = NSSearchPathForDirectoriesInDomains(NSDocumentDirectory, NSUserDomainMask, YES); 
NSArray *path4 = NSSearchPathForDirectoriesInDomains(NSDocumentDirectory, NSUserDomainMask, YES); 
NSString *documentDirectory = [path objectAtIndex:0]; 
NSString *documentDirectory2 = [path2 objectAtIndex:0]; 
NSString *documentDirectory3 = [path3 objectAtIndex:0]; 
NSString *documentDirectory4 = [path4 objectAtIndex:0]; 

NSString *fullPath = [documentDirectory stringByAppendingPathComponent:myGrabbedImage]; 
NSString *fullPath2 = [documentDirectory2 stringByAppendingPathComponent:myGrabbedImage2]; 
NSString *fullPath3 = [documentDirectory3 stringByAppendingPathComponent:myGrabbedImage3]; 
NSString *fullPath4 = [documentDirectory4 stringByAppendingPathComponent:myGrabbedImage3]; 

NSData *data = [NSData dataWithContentsOfFile:fullPath]; 
NSData *data2 = [NSData dataWithContentsOfFile:fullPath2]; 
NSData *data3 = [NSData dataWithContentsOfFile:fullPath3]; 
NSData *data4 = [NSData dataWithContentsOfFile:fullPath4]; 

if ([myGrabbedImage isEqualToString:@"myGrabbedImage.png"]) 
{ 
[[self firstImageView]setImage:[UIImage imageWithData:data]]; 
} 
else if ([myGrabbedImage2 isEqualToString:@"myGrabbedImage2.png"]) 
{ 
    [[self secondImageView]setImage:[UIImage imageWithData:data2]]; 
} 
else if ([myGrabbedImage3 isEqualToString:@"myGrabbedImage3.png"]) 
{ 
    [[self thirdImageView]setImage:[UIImage imageWithData:data3]]; 
} 
else 
{ 
    [[self fourthImageView]setImage:[UIImage imageWithData:data4]]; 
} 

Тогда у меня есть это в моем методе UIImagePickerController:

- (void)imagePickerController:(UIImagePickerController *)picker didFinishPickingMediaWithInfo:(NSDictionary *)info 
{ 
UIImage *image1 = [info objectForKey:UIImagePickerControllerOriginalImage]; 

NSData *data = UIImagePNGRepresentation(image1); 
NSString *myGrabbedImage = @"myGrabbedImage.png"; 
NSArray *path = NSSearchPathForDirectoriesInDomains(NSDocumentDirectory, NSUserDomainMask, YES); 
NSString *documentDirectory = [path objectAtIndex:0]; 
NSString *fullPathToFile = [documentDirectory stringByAppendingPathComponent:myGrabbedImage]; 

[data writeToFile:fullPathToFile atomically:YES]; 
if (picker == imagePickerController) 
{ 
    [[self firstImageView]setImage:image1]; 
} 
else if (picker == imagePickerController2) 
{ 
    [[self secondImageView]setImage:image1]; 
} 
else if (picker == imagePickerController3) 
{ 
    [[self thirdImageView]setImage:image1]; 
} 
else if (picker == imagePickerController4) 
{ 
    [[self fourthImageView]setImage:image1]; 
} 
[self dismissViewControllerAnimated:YES completion:nil]; 
} 

грубой, то ViewDidLoad просто показывает одно изображение. Но как я могу заставить его загрузить все 4 UIImageView.

Заранее спасибо
