How to set the background color of UIPickerView on iOS 7 using SDK 7?

Question

How to set the background color of UIPickerView on iOS 7 using SDK 7 and use a standard picker on iOS 5 and 6? It's transparent by default on iOS 7.

Answer 1

I have added UIView under UIPickerView with code:

CGRect framePickerView = CGRectMake(0, self.view.frame.size.height, self.view.frame.size.width, 216);
pickerView = [[[UIView alloc] initWithFrame:framePickerView] autorelease];
pickerView.backgroundColor = [UIColor whiteColor];
[self.view addSubview:pickerView];
[pickerView addSubview:picker];

instead the code:

[self.view addSubview:picker];
