IBOutlet UIImageView - iphone

Question

I got 30 of these codes, with the same implementation:
// .h
#interface ViewController : UIViewController{
IBOutlet UIImageView *circle;
IBOutlet UIImageView *circle2;
}
#property (nonatomic, retain) IBOutlet UIImageView *circle;
#property (nonatomic, retain) IBOutlet UIImageView *circle2;
// .m
#implementation ViewController
#synthesize circle;
#synthesize circle2;
- (void)viewDidLoad
{
circle = [[UIImageView alloc]
initWithImage:[UIImage imageNamed:#"Circle.png"]];
circle2 = [[UIImageView alloc]
initWithImage:[UIImage imageNamed:#"Circle.png"]];
}
And somewhere in my code, Im adding it as a subview.
My problem is,Is there a way to make it shorter, for it to be maintainable.

Answer 1

You can use one IBOutletCollection instead of 30 IBOutlets. You probably want to set the tag on each UIImageView though, so you can still tell them apart.
(This answer assumes you use a nib. Remove the lines where you instantiate the UIImageViews in viewDidLoad if so.)

Answer 2

If you use name like - Circle1.png, Circle2.png, then you can go for for loop for creating this in a loop.
Something like -
for (int i = 0; i < imageCount ; i++ ) {
circle = [[UIImageView alloc]
initWithImage:[UIImage imageNamed:[NSString stringWithFormat: #"Circle%d.png" , i]]];
}

Answer 3

Is there a pattern to where you are putting these views in their superview? If so, you could use a for loop that goes to 30 and programmatically create the views and add them to their superview.
So for example:
for (i = 0; i < 100; i++)
{
UIImageView* circle = [[UIImageView alloc]
initWithImage:[UIImage imageNamed:#"Circle.png"]];
[self.view addSubview:circle];
}
Would add 100 of the image views you would want. Of course you will need to adjust the positions of each of these views in the loop, but this is the general idea.

Answer 4

while creating this viewcontroller pass the frame as a parameter.thats the only thing changing rite??.the image is same and as there are no other properties .. it may work
