我不了解並且不知道如何解決的ImagePicker IOS錯誤

Question

我希望用戶在按下按鈕時通過操作從iPhone中選擇一個圖像（通過action：buttonClicked），並且希望該圖像在我擁有的imageview上查看（imageAddPicture是該圖像視圖的名稱）

我發現了很多信息，但是當我使用此代碼時，出現以下錯誤：

自我，釋放，picker.sourceType =（sender == buttonClicked），...

有人能幫助我嗎？ （我是stackoverflow.com的新手，但我確實需要幫助，我會盡力幫助其他人）這是我使用的代碼：

-(IBAction)buttonClicked:(id)sender
{
    UIImagePickerController *picker = [[UIImagePickerController alloc] init];
    picker.delegate = self;
    picker.allowsImageEditing = YES;
    picker.sourceType = (sender == buttonClicked) ?    UIImagePickerControllerSourceTypeCamera :
    UIImagePickerControllerSourceTypeSavedPhotosAlbum;
    [self presentModalViewController: picker animated:YES];
    [picker release];
}
-(IBAction)selectExitingPicture
{
    if([UIImagePickerController isSourceTypeAvailable:
        UIImagePickerControllerSourceTypePhotoLibrary])
    {
        UIImagePickerController *picker= [[UIImagePickerController alloc]init];
        picker.delegate = self;
        picker.sourceType = UIImagePickerControllerSourceTypePhotoLibrary;
        [self presentModalViewController:picker animated:YES];
        [picker release];
    }
}

-(void)imagePickerController:(UIImagePickerController *)picker
      didFinishPickingImage : (UIImage *)image
                 editingInfo:(NSDictionary *)editingInfo
{
    imageAddPicture.image = image;
    [picker dismissModalViewControllerAnimated:YES];
}
-(void)imagePickerControllerDidCancel:(UIImagePickerController *)  picker
{
    [picker dismissModalViewControllerAnimated:YES];
}

您正在自動引用計數中處理項目。 因此，您無需釋放對象。 只需刪除此行。 智利:)

picker.sourceType = (sender == buttonClicked) ?    UIImagePickerControllerSourceTypeCamera :
    UIImagePickerControllerSourceTypeSavedPhotosAlbum;

這條線應該是

picker.sourceType = (sender == buttonClicked:) ?    UIImagePickerControllerSourceTypeCamera :
    UIImagePickerControllerSourceTypeSavedPhotosAlbum;
