如何确定图像是从库中还是从相机中获取的

Question

我想通过if语句检查是否从相机胶卷中拾取图像或由内置相机拍摄图像。 如何通过if语句执行此操作？ 谢谢你的帮助！

码：

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

if (picker.sourceType == UIImagePickerControllerSourceTypeCamera) {

    toolbar.hidden = NO;
}

if (picker.sourceType == UIImagePickerControllerSourceTypePhotoLibrary) {

    toolbar.hidden = NO;
}

if (picker.sourceType == UIImagePickerControllerSourceTypeSavedPhotosAlbum) {

    toolbar.hidden = NO;
}

else{

    toolbar.hidden = YES;
}

imgView.image = [info objectForKey:@"UIImagePickerControllerEditedImage"];

[self dismissViewControllerAnimated:YES completion:nil];
}

Answer 1

只需检查sourceType ：

if (picker.sourceType == UIImagePickerControllerSourceTypeCamera) {
    //image taken with camera
}
else{
    //image taken from camera roll
}

在imagePickerController:didFinishPickingMediaWithInfo:方法中执行此操作。
