我是一個新的iPhone應用程序開發人員，我需要創建一個應用程序，如照片gallery.Now我的問題是我donno如何將圖像保存到相冊。Three20保存圖像？（關閉）

我建立我的項目是沒有錯誤沒有wiening me.in我的模擬器可以運行該項目。

但我看到任何我添加的東西。希望可以幫助我。謝謝。

我的代碼在這裏。

你有沒有錯誤？你在哪一部分？ – Aravindhan 2011-04-29 05:27:41

嗨，我編輯ady。 – ahyong87 2011-04-29 06:25:04

如果你需要的是保存到相冊上的圖片，你可以使用：

UIImage *myImage; 
UIImageWriteToSavedPhotosAlbum(myImage,nil,nil,nil);

如果這不是你的問題，然後我不明白這一點。如果你不告訴我們問題在哪裏，發佈三頁代碼是非常沒用的。
