I have created a sample picker-view which will display some details. Setting the Background color using:
_pickerView.backgroundColor = [UIColor redColor];
doesn't seems to be working . But I wish I could create a picker view like the below image
What I was trying to do is , the entire PickerView background color should not be white, it should fill with the UIColor which I am giving. Is that possible?? How it can be done ??
Addition to Nina's answer, below are some of the good custom Picker view controls which will be good to use in terms of performance and customizable.
I wrote a custom picker view that uses a UITableView as it's starting point. Feel free to customize it however you want.
You can change selected color by putting tableview cell in it.
- (UIView *)pickerView:(UIPickerView *)pickerView viewForRow:(NSInteger)row forComponent:(NSInteger)component reusingView:(UIView *)view {
UITableViewCell *cell = (UITableViewCell *)view;
if( cell == nil ) {
cell = [[[UITableViewCell alloc] initWithStyle:UITableViewCellStyleDefault reuseIdentifier:nil] autorelease];
[cell setBackgroundColor:[UIColor redColor]];
[cell setBounds: CGRectMake(0, 0, cell.frame.size.width -20 , 44)];
cell.textLabel.text = [self.userNameArray objectAtIndex:row];
cell.userInteractionEnabled = NO;
}
return cell;
}
It is hard to customize a UIPickerView.
You might opt to use it in its default appearance or trying to simulate a UIPickerView using another UIKit component such as UITableView. There are some libs that are using UITableView to simulate a more flexible UIPickerView.
UIPickerView has subviews. Assigning an image to a view and adding it to the subview at index 2, would change the background of pickerview.
I had had a same kinda problem :-) See my question here!! Customize UIPickerView's Skin with images
Or you can use AFPickerView
The API does not provide a way to change the style and color of selection dialer. You can change only inner view of the picker how u want to design. As the UIPickerView don't have the UI_APPEARANCE_SELECTOR.
