## 一：效果  ## 二：代碼 相機部分就簡單多了，幾行代碼調用而已，但是如果你要是想實現更多豐富的功能，需要自己寫。利用AssetsLibrary.framework，利用這個框架可以獲得手機上的所有相冊圖片，寫一個圖片選擇控制器。 ~~~ - (void)openCamera { [self openImagePickerController:UIImagePickerControllerSourceTypeCamera]; } - (void)openAlbum { // 如果想自己寫一個圖片選擇控制器，得利用AssetsLibrary.framework，利用這個框架可以獲得手機上的所有相冊圖片 // UIImagePickerControllerSourceTypePhotoLibrary > UIImagePickerControllerSourceTypeSavedPhotosAlbum [self openImagePickerController:UIImagePickerControllerSourceTypePhotoLibrary]; } - (void)openImagePickerController:(UIImagePickerControllerSourceType)type { if (![UIImagePickerController isSourceTypeAvailable:type]) return; UIImagePickerController *ipc = [[UIImagePickerController alloc] init]; ipc.sourceType = type; ipc.delegate = self; [self presentViewController:ipc animated:YES completion:nil]; } ~~~ 實現代理 ~~~ #pragma mark - UIImagePickerControllerDelegate /** * 從UIImagePickerController選擇完圖片后就調用（拍照完畢或者選擇相冊圖片完畢） */ - (void)imagePickerController:(UIImagePickerController *)picker didFinishPickingMediaWithInfo:(NSDictionary *)info { [picker dismissViewControllerAnimated:YES completion:nil]; // info中就包含了選擇的圖片 UIImage *image = info[UIImagePickerControllerOriginalImage]; // 添加圖片到photosView中 [self.photosView addPhoto:image]; // dispatch_after(dispatch_time(DISPATCH_TIME_NOW, (int64_t)(0.25 * NSEC_PER_SEC)), dispatch_get_main_queue(), ^{ // self.picking = NO; // }); } ~~~
