Answer 1

Use this:

// Cell.m

@interface Cell ()

@property (strong, nonatomic) UIPickerView *pickerView;

@end    

@implementation

- (void)initPickerView {
    _pickerView = [[UIPickerView alloc] init];
}

- (void)showPickerView {
    CGRect pickerViewFrame = _pickerView.frame;
    pickerViewFrame.origin.y = self.frame.size.height;
    _pickerView.frame = pickerViewFrame;

    [self addSubview:_pickerView];

    CGRect cellFrame = self.frame;
    cellFrame.size.height += pickerViewFrame.size.height;
    self.frame = cellFrame;
}

- (void)hidePickerView {
    CGRect cellFrame = self.frame;
    cellFrame.size.height -= _pickerView.frame.size.height;
    self.frame = cellFrame;

    [_pickerView removeFromSuperview];
}

@end

First of all, initialize picker view with initPickerView method in any place before using the view. Then, when you need picker view to appear use showPickerView . And use hidePickerView to remove it from the cell.
