Answer 1

There is no any API for change apperiance of UIDatePicker.

You can make a pretty convincing replica yourself using a UIPickerView

    - (NSInteger)numberOfComponentsInPickerView:(UIPickerView *)pickerView {
return a;}

- (NSInteger)pickerView:(UIPickerView *)pickerView numberOfRowsInComponent:(NSInteger)component {
return b;}

- (UIView *)pickerView:(UIPickerView *)pickerView viewForRow:(NSInteger)row forComponent:(NSInteger)component reusingView:(UIView *)view {

UILabel *lblpkr= [[UILabel alloc] initWithFrame:CGRectMake(p,q,r,s)];
[lblpkr setBackgroundColor:[UIColor clearColor]];
[lblpkr setTextColor:[UIColor blueColor]];
[lblpkr setFont:[UIFont boldSystemFontOfSize:x]];
[lblpkr setText:[NSString stringWithFormat:@"%d",row]];

return lblpkr;}
