在demo中按钮的返回动作是错误的：

(void)didTappedReturnButton:(UIButton *)button
{
if (self.navigationController == nil) {
[self dismissViewControllerAnimated:YES completion:nil];
} else {
if (self.parentViewController) {
[self.parentViewController dismissViewControllerAnimated:YES completion:nil];
} else {
[self.navigationController popViewControllerAnimated:YES];
}
}
}
这里的。 if (self.parentViewController) {
[self.parentViewController dismissViewControllerAnimated:YES completion:nil];
} else {
[self.navigationController popViewControllerAnimated:YES];
}这个判断存在错误，应当改为这样：
(void)didTappedReturnButton:(UIButton *)button
{
if (self.navigationController == nil) {
[self dismissViewControllerAnimated:YES completion:nil];
} else {
if (!self.parentViewController.parentViewController) {
[self.parentViewController dismissViewControllerAnimated:YES completion:nil];
} else {
[self.navigationController popViewControllerAnimated:YES];
}
}
}
