在iOS中单击后如何保存照片[重复]

Question

这是我启动相机的按钮：

-(IBAction)TakePhoto{


    // check if camera exists...to test on simulator
    if ([UIImagePickerController isSourceTypeAvailable:UIImagePickerControllerSourceTypeCamera])  {


        picker=[[UIImagePickerController alloc] init];
        picker.delegate =self;
        [picker setSourceType:UIImagePickerControllerSourceTypeCamera];
        [self presentViewController:picker animated:YES completion:NULL];

    }
    else
    {
     UIAlertView *alert = [[UIAlertView alloc] initWithTitle: @"" message: @"Camera not available on this device" delegate: nil cancelButtonTitle:@"Ok" otherButtonTitles:nil]; [alert show];

    }



}

我只是希望它把它保存到照片库，然后再回到视图控制器。

让它像这样工作：添加了这 2 个代表，didFinishPickingMediaWithInfo 和

imagePickerControllerDidCancel.

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


    image= [info objectForKey:UIImagePickerControllerOriginalImage];

    UIImageWriteToSavedPhotosAlbum(image, nil, nil, nil);
    [imageView setImage:image];

    [self dismissViewControllerAnimated:YES completion:NULL];



}

-(void)imagePickerControllerDidCancel:(UIImagePickerController *)picker
{

    [self dismissViewControllerAnimated:YES completion:NULL];
}

Answer 1

只要做：

- (void)imagePickerController:(UIImagePickerController *)picker didFinishPickingMediaWithInfo:(NSDictionary *)info {
    UIImage *image = [info objectForKey:UIImagePickerControllerOriginalImage];
    UIImageWriteToSavedPhotosAlbum(image, nil, nil, nil);
    [picker dismissViewControllerAnimated:YES completion:nil];
}
