Answer 1

Change the inView parameter in

[testPopoverController presentPopoverFromRect:rect inView:[UIApplication sharedApplication].keyWindow permittedArrowDirections:UIPopoverArrowDirectionDown animated:YES];

to

[testPopoverController presentPopoverFromRect:rect inView:"your current View Controller's view" permittedArrowDirections:UIPopoverArrowDirectionDown animated:YES];

And make sure it is in dispatch block

  dispatch_async(dispatch_get_main_queue(), ^{

});

Also kip changing your rect origin n size values if it is within the bounds
