用户使用相机拍摄照片后,我试图用按钮将照片保存到相机胶卷,但我不知道为什么我的照片不能保存在照片库中!
这是我的代码:
-(IBAction)savePhoto{
UIImageWriteToSavedPhotosAlbum(img.image,nil, nil, nil);
}
-(IBAction)takePic {
ipc = [[UIImagePickerController alloc]init];
ipc.delegate = self;
ipc.sourceType = UIImagePickerControllerSourceTypeCamera;
[self presentModalViewController:ipc animated:YES];
}
- (void)imagePickerController:(UIImagePickerController *)picker didFinishPickingMediaWithInfo:(NSDictionary *)info {
img.image = [[info objectForKey:UIImagePickerControllerOriginalImage]retain];
[[picker parentViewController]dismissModalViewControllerAnimated:YES];
[picker release];
}
变量名称ipc
为UIImagePickerController
,img
为UIIMageView
。
我的问题是什么?

首先确保您正在呼叫savePhoto
。然后你可以添加一个断言来检查图像是不是nil:
- (IBAction) savePhoto {
NSParameterAssert(img.image);
UIImageWriteToSavedPhotosAlbum(img.image, nil, nil, nil);
}
