UIImageView在水平UIPicker組件顯示在iPhone模擬器上但不是在實際的iPhone上

我用UIImageViews（而不是文本標籤等）創建了水平的UIPickerView。基本上工作正常，除了圖像只顯示在iPhone模擬器，但不是在實際的iPhone。UIImageView在水平UIPicker組件顯示在iPhone模擬器上但不是在實際的iPhone上

我在爲iOS v 4.3版本構建。

我完全難住，一直在努力爭取相當一段時間！

謝謝:)

確保圖像名稱rss.png，檢查瓶蓋 – 2012-01-11 13:29:14

...然後清潔並重建項目... – Nekto 2012-01-11 13:42:12

感謝您的反饋 - 我仔細檢查了文件名/箱＆乾淨的構建，但不幸的是沒有喜悅。 – user1143230 2012-01-11 14:06:58

你爲什麼初始化UIImageView的兩倍，同時創造？我認爲這是問題。相反，嘗試

UIImageView *oneView = [[UIImageView alloc] initWithFrame:CGRectMake(0, 0, 50, 50)]; 
[oneView setImage: one];
