这个怎么样？
并且不要使用NSTextFieldAndStepperDatePickerStyle，请...

- (void)viewDidLoad {
    [super viewDidLoad];

    // _picker is NSDatePicker as outlet
    _picker.bordered = NO;
    _picker.wantsLayer = YES;
    _picker.layer.borderWidth = 1;
    _picker.layer.borderColor = [NSColor lightGrayColor].CGColor;
}
