UIImagePickerController

1.你無法得知在相簿中該相片的檔名
2.這是我之前的作法，提供您參考：[code]
- (void)imagePickerController:(UIImagePickerController *)picker didFinishPickingImage:(UIImage *)image editingInfo:(NSDictionary *)editingInfo{
    //將ImagePicker取得的圖片指定給我們的ImageView
    myImageView.image=image;    

   //將取得的UIImage轉換為PNG格式的NSData
    NSData *imageData = UIImagePNGRepresentation(image);

   //自行指定儲存的檔名
    NSString *paths=NSTemporaryDirectory();    
    NSString *filename=@"temp.png";
    NSString *pathoffilesave=[paths stringByAppendingPathComponent:filename];   

   //儲存
    [imageData writeToFile:pathoffilesave atomically:NO];    
    
    //關閉ImagePicker
    [picker dismissModalViewControllerAnimated:YES];  
}
[/code]
