我已经编写了从相机捕获图像的代码,并且我想将该图像保存在文档目录中。我已经完成了代码,但我认为图像没有存储文档目录。因为当我检索图像时,相机图像不在文档目录中,所以我的代码:
- (IBAction)takePhoto {
UIImagePickerController *picker = [[UIImagePickerController alloc] init];
picker.delegate = self;
picker.allowsEditing = YES;
picker.sourceType = UIImagePickerControllerSourceTypeCamera;
[self presentViewController:picker animated:YES completion:NULL];
}
- (void)imagePickerController:(UIImagePickerController *)picker didFinishPickingMediaWithInfo:(NSDictionary *)info {
UIImage *cameraImage = info[UIImagePickerControllerEditedImage];
self.tempView.image = cameraImage;
[_chosenImages addObject:_tempView.image];
[picker dismissViewControllerAnimated:YES completion:NULL];
}
id n = [array3 lastObject];
NSLog(@"The id is=%@",n);
NSError *error;
NSString *aDocumentsDirectory = [NSSearchPathForDirectoriesInDomains(NSDocumentDirectory, NSUserDomainMask, YES) lastObject];
NSString *dataPath = [aDocumentsDirectory stringByAppendingPathComponent:[NSString stringWithFormat:@"%@",n]];
[[NSFileManager defaultManager] createDirectoryAtPath:dataPath withIntermediateDirectories:NO attributes:nil error:&error];
NSInteger anIndex = 0;
for (UIImage *anImage in _chosenImages) {
NSString *anImageName = [NSString stringWithFormat:@"%d.png", anIndex++];
NSString *anImagePath = [NSString stringWithFormat:@"%@/%@", dataPath, anImageName];
NSLog(@"the path is=%@",anImagePath);
NSData *anImageData = UIImagePNGRepresentation(anImage);
[anImageData writeToFile:anImagePath atomically:YES];
