add image to uimageview dynamically from an array of images - ios

Question

I'm able to add a label and text field dynamically but the image doesn't display unless I used the actually name of the image.
This works
UIImage *individualTopImage = [UIImage imageNamed:#"photo1.png"];
I need to use the for loop and display all the images in the array.
//lets create views
NSInteger numberTopOfViews = topImages.count;
for (int i = 0; i < numberTopOfViews; i++) {
//set the origin of the sub view
CGFloat myOrigin = i * self.view.frame.size.width;
//create the sub view and allocate memory
UIView *myView = [[UIView alloc] initWithFrame:CGRectMake(myOrigin, 0, self.view.frame.size.width, self.view.frame.size.height)];
//set the background to white color
myView.backgroundColor = [UIColor whiteColor];
//create a label and add to the sub view
CGRect myFrame = CGRectMake(10.0f, 10.0f, 200.0f, 25.0f);
UILabel *myLabel = [[UILabel alloc] initWithFrame:myFrame];
myLabel.text = [NSString stringWithFormat:#"This is page number %d", i];
myLabel.font = [UIFont boldSystemFontOfSize:16.0f];
myLabel.textAlignment = NSTextAlignmentLeft;
[myView addSubview:myLabel];
//create a text field and add to the sub view
myFrame.origin.y += myFrame.size.height + 10.0f;
UITextField *myTextField = [[UITextField alloc] initWithFrame:myFrame];
myTextField.borderStyle = UITextBorderStyleRoundedRect;
myTextField.placeholder = [NSString stringWithFormat:#"Enter data in field %i", i];
myTextField.tag = i+1;
[myView addSubview:myTextField];
//create a uiimage and add to sub view
myFrame.origin.y +=myFrame.size.height +50.f;
//UIImage *individualTopImage = [UIImage imageNamed:#"photo1.png"];
UIImage *individualTopImage = [UIImage imageNamed:[NSString stringWithFormat:#"%#.png",[topImages objectAtIndex:i]]];
UIImageView *topImageView = [[UIImageView alloc] initWithImage: individualTopImage];
[topImageView setFrame:CGRectMake(0, 0, myFrame.size.width,myFrame.size.height )];
[myView addSubview:topImageView];
//set the scroll view delegate to self so that we can listen for changes
self.myScrollView.delegate = self;
//add the subview to the scroll view
[self.myScrollView addSubview:myView];
}
