Question

I’ve been trying for an hour and nothing I do can seem to make this show the image:

UIImageView*logo=[[UIImageView alloc] initWithImage:[UIImage imageNamed: @"logo.png"]];
logo.frame=pos; // a CGRect I previously created
self.taskbarlogo=logo;
[logo release];
[self.popupwindow addSubview:self.taskbarlogo];

logo.png is definitely there in the project

this is the last subview added to self.popupwindow so it should be on top

the hidden property is never handled anywhere so it should be visible

The following NSLog confirms the placement of the UIImageView’s frame:

NSLog(@"frame: %f %f %f %f",self.taskbarlogo.frame.origin.x,self.taskbarlogo.frame.origin.y, self.taskbarlogo.frame.size.width, self.taskbarlogo.frame.size.height);

It reports:

frame: 20.000000 20.000000 96.000000 33.000000

this is certainly onscreen, or certainly should be as my superview’s frame is much larger than this

what am I missing?! there is no crash, no errors, just…. no image.

Check the file inspector (one of the right side tabs) under Target Membership and make sure the image belongs to all targets where the resource is desired. Also call bringSubviewToFront to be sure it’s on top.
