iPhone標題攝像頭，imageview不顯示拍攝的照片

我被要求製作一個應用程序，提供關於他們的貓的隨機標題。我有兩個問題，我一步一步跟着教程，沒有任何工作。 1.當拍攝或選擇一張照片時，它不會顯示在UIImageView中，故事板中的每一個東西都會被喜歡，我只是不明白。另外，我在製作隨機標題的地方製作了一個IBAction，當它按下按鈕時，它可以正常工作，無論如何，當圖片被拍攝或選擇時，標題會自動顯示在哪裏？這是我的.M文件中的代碼。當談到製作應用程序時，我是一名初學者。iPhone標題攝像頭，imageview不顯示拍攝的照片

} 

- (void)viewDidLoad 
{ 

    [super viewDidLoad];

任何幫助都會做。我的SDK是iOS 6.1

您上面的代碼沒有imageView。你想在這裏做什麼？ image = [info objectForKey：UIImagePickerControllerOriginalImage]; – 2013-03-14 22:05:24

「image = [info objectForKey：UIImagePickerControllerOriginalImage];」什麼是形象？它應該是'urImageView.image = ...' – 7usam 2013-03-14 22:05:55

什麼是meathod設置拍攝到imageview我有嗎？ – goofballcent 2013-03-15 01:03:48

圖像是自動釋放的。將imageView設置爲超出範圍之前，或保留它。如果你把它連接到任何東西，它應該留在記憶和展示。
