Question

I started working on an iphone app and since I am not as experienced as most I can not figure out how to recreate dynamically imageviews, labels and buttons. Basically there will be an array in which some data is stored. However the size of the array will vary and such I can not make a static VC on the storyboard. I would like to use the following template and then the array should use this template to recreate it as many times as it needs :

The previous answers about using a UITableView to display each entry in the array as a cell is the way you want to go. To answer your question about “dynamically creating” each item, you would want to create each UI element in your cellForRowAtIndexPath like this:

UIImageView *imageView = [[UIImageView alloc] initWithFrame:CGRectMake(x,y,w,h)];
[imageView setTag:1];
[cell addSubview:imageView];
[imageView release];

UILabel *label = [[UILabel alloc] initWithFrame:CGRectMake(x,y,w,h)];
[label setFont:[UIFont systemFontOfSize:X]];
[label setTag:2];
[cell addSubview:label];
[label release];

UIButton *button1 = [[UIButton alloc] initWithFrame:CGRectMake(x,y,w,h)];
[button1 setImage:[UIImage imageNamed:@"ABC"] forState:UIControlStateNormal];
[button1 addTarget:self action:@selector(someMethod:) forControlEvents:UIControlEventTouchUpInside];
[button1 setTag:3];
[cell addSubview:button1];
[button1 release];

etc

Then in your willDisplayCell method you will set the contents of any UI item that change for each row like this:

UIImageView *imageView = (UIIamgeView *)[cell viewWithTag:1;
UILabel *label = (UILabel *)[cell viewWithTag:2];

[imageView setImage:[UIImage imageNamed:@"XYZ"]];
[label setText:@"XYZ"];
