Question

I just want to know why the selection indicator looks like this in my iPad App. By “like this” I mean the first half has one color pattern and the other one has another. I’m creating my UIPickerView programatically like this:

pickerView = [[UIPickerView alloc] init];
pickerView.showsSelectionIndicator = YES;
pickerView.delegate = self;
pickerView.dataSource = self;

txtFolder.inputView = pickerView;

I need the pickerview to show the same color pattern. Any ideas?

Answer 1

I have been fighting with the same issue the whole day today.

I have similar code:

pickerView = [[UIPickerView alloc] init];
pickerView.showsSelectionIndicator = YES;
pickerView.delegate = self;
pickerView.dataSource = self;
[pickerView selectRow:0 inComponent:0 animated:NO];

txtFolder.inputView = pickerView;

So if you perform ‘pickerView.showsSelectionIndicator = YES’ after selecting a row it solves the problem.

The solution:

pickerView = [[UIPickerView alloc] init];
pickerView.delegate = self;
pickerView.dataSource = self;
[pickerView selectRow:0 inComponent:0 animated:NO];
pickerView.showsSelectionIndicator = YES;

txtFolder.inputView = pickerView;

Alex, try this, may be it will help you.

UPDATE:

But the only true way is to show a picker within a popover. The cause of the issue is that a picker is not suitable for the main screen!
