Question

I have this very simple code or at least i think it’s simple.

// Implement loadView to create a view hierarchy programmatically, without using a nib.
- (void)loadView {  
CGRect rect = CGRectMake(0.0f, 20.0f, 320.0f, 216.0f); 

UIPickerView *myPickerView = [[UIPickerView alloc] initWithFrame:rect]; 

self.view = myPickerView;
[myPickerView release];
}

I am running a general View Based template with XCode. I can see the loadView getting called but i get an black frame instead of the UIPickerView.

What am i doing wrong ?

/donnib

Have you implemented the picker’s datasource methods? You need it otherwise it won’t show.
