我是iphone的新手。在我的小应用程序中,如何从照片库获取图像路径。我使用以下代码来获取图像并放置在imageview中。
-(IBAction) selectimage
{
UIImagePickerController * picker = [[UIImagePickerController alloc] init];
picker.delegate = self;
//picker.sourceType = UIImagePickerControllerSourceTypeSavedPhotosAlbum;
if([UIImagePickerController isSourceTypeAvailable:UIImagePickerControllerSourceTypePhotoLibrary])
[self presentModalViewController:picker animated:YES];
NSLog(@"UIPicker=%@",picker);
}
- (void)imagePickerController:(UIImagePickerController *)UIPicker didFinishPickingImage:(UIImage *)info editingInfo:(NSDictionary *)dictionary
{
imageView.image=info;
[UIPicker dismissModalViewControllerAnimated:YES];
NSLog(@"UImage path= %@",imageView.image);
}
Its succefully placed to Imageview. But i cant get its imagepath for storing into DB. I'm using NSLog("Image path= %@",imageview.image); it shows "Image Path= UIImage: 0x6819790" in console. How can i get its path and how to retrieve photos from photo library.
它成功地放置在Imageview上。但是我无法将其imagepath存储到DB中。我正在使用NSLog(“Image path =%@”,imageview.image);它在控制台中显示“Image Path = UIImage:0x6819790”。如何获取其路径以及如何从照片库中检索照片。
My current process goes like this: UIImagePickerController -> User Chooses Image from Photos -> chosenImage is set to instance of UIImageView -> Now I want to take this image and store it in the DB.
我当前的过程如下:UIImagePickerController - >用户从照片中选择图像 - > selectedImage设置为UIImageView的实例 - >现在我想拍摄此图像并将其存储在数据库中。
