如何返回到原始視圖使用彈出視圖控制器

Question

我有一個按鈕&當我點擊按鈕它移動到另一個視圖控制器，然後有一個後退按鈕，當我點擊它，它需要時間回去

我做它像這樣

GeoNewsViewController*targetController=[[GeoNewsViewController alloc] init]; 
[self.navigationController pushViewController:targetController animated:YES]; 

Answer 1

-(void) viewWillDisappear:(BOOL)animated{ 

    //remove unnecessary code here if u have 

    //if u use any webservice then cancel connection here 

    //stop any animations if 

} 

您可以通過編程回去動畫這樣

 [self.navigationController popViewControllerAnimated:YES];
