UIImagePickerController didFinishPickingMediaWithInfo

Question

Bellow是我的didFinishPickingMediaWithInfo方法，我知道我有很多不必要的代碼，保留，發佈等等......但這是我能夠使它工作的方式，我害怕破壞它試圖優化它。

任何人都可以幫助我脫掉不必要的東西，並有此方法清潔？

此外，我有一個視圖控制器，將加載4張照片（相機膠捲或相機），並在第二或第三張照片選擇後，應用程序崩潰或至少，我得到了下面的警報之一。我做錯了什麼？謝謝！

- (void)imagePickerController:(UIImagePickerController *)picker didFinishPickingMediaWithInfo:(NSDictionary *)info { 

    UIImage *img = [info objectForKey:UIImagePickerControllerEditedImage]; 
    if(!img) img = [info objectForKey:UIImagePickerControllerOriginalImage]; 

    uiimvImagem.image = img; //why bother? 
    uiimvImagem.alpha = 0; //why bother? 
    UIImageView *tempImageView = [[UIImageView alloc] initWithImage:img]; 
    self.uiimvImagem = tempImageView; //Make sure your self.uiimvImagem is a retained property! Also, don't forget to nil it out in your dealloc method 
    [tempImageView release]; 

    CGRect frame = uiimvImagem.frame; 
    frame.size.width = 359; 
    frame.size.height = img.size.height/(img.size.width/359); 
    uiimvImagem.frame = frame; 

    uisv1.showsVerticalScrollIndicator = NO;

這應該是一個好一點 - 雖然我不知道剩下的是如何連接起來（即財產申報和我m不確定在哪裏分配uisv1）。還有一些看起來不正確的東西 - 您將圖像分配給圖像視圖，但是隨後使用新分配的UIImageView運行整個過程。
