iphone开发 调用相机拍照

调用相机：

{UIImagePickerController *picker = [[UIImagePickerController alloc] init];picker.delegate = self;picker.allowsImageEditing = YES;picker.sourceType =UIImagePickerControllerSourceTypeCamera; [self presentModalViewController:picker animated:YES];[picker release];}

回调：

- (void)imagePickerController:(UIImagePickerController *)picker         didFinishPickingImage:(UIImage *)image                  editingInfo:(NSDictionary *)editingInfo {        [picker dismissModalViewControllerAnimated:YES];}- (void)imagePickerControllerDidCancel:(UIImagePickerController *)picker {        [picker dismissModalViewControllerAnimated:YES];}
