Question

If I set this UIImageView as an IBOutlet it works fine and shows up in the sim. But programmatically it isn’t working. I think I am missing a step or forgetting a line of code.

It is declared as

@property (nonatomic,retain) UIImageView  *circleView;  

and the implementation

self.circleView.frame = CGRectMake(0, 0, self.view.frame.size.width,   self.view.frame.size.height);
    self.circleView.center = self.view.center;
    [self.view addSubview:circleView];

Answer 1

You just forgot to initialize your UIImageView that’s why it’s not working …

self.circleView = [[UIImageView alloc] init];
self.circleView.frame = CGRectMake(0, 0, self.view.frame.size.width,   self.view.frame.size.height);
    self.circleView.center = self.view.center;
    [self.view addSubview:circleView];
