IOS獲取圖片音頻方法----UIImagePickerController

1 用途： 是系統(tǒng)提供的用來獲取圖片和視頻的接口；

2獲取圖片途徑：拍照，圖庫，相冊獲取

enum {

   UIImagePickerControllerSourceTypePhotoLibrary ,//來自圖庫

   UIImagePickerControllerSourceTypeCamera ,//來自相機

   UIImagePickerControllerSourceTypeSavedPhotosAlbum //來自相冊

};

3 步驟：

1. 初始化一個UIImagePickerController類

2. 設(shè)置數(shù)據(jù)來源類型，—— 上面2

3. 設(shè)置代理

4. 如果需要對圖片進行修改，allowsEditing = yes

4 具體代碼實現(xiàn)

#pragma mark 選擇圖片

- (IBAction)selectImage:(UITapGestureRecognizer *)sender{
    //圖片選擇控制器
    UIImagePickerController *pickerController=[[UIImagePickerController alloc] init];

    //選擇你要使用的類型 圖集，相冊，相機   pickerController.sourceType=UIImagePickerControllerSourceTypePhotoLibrary;

    pickerController.delegate=self;
    pickerController.allowsEditing=YES;
    [self presentViewController:pickerController animated:YES completion:nil];

}

#pragma mark delegate
-(void)p_w_picpathPickerController:(UIImagePickerController *)picker didFinishPickingMediaWithInfo:(NSDictionary<NSString *,id> *)info{
   //根據(jù)選擇的圖片 設(shè)置頭像

  _IconImage.p_w_picpath=info[@"UIImagePickerControllerOriginalImage"];

   [picker dismissViewControllerAnimated:YES completion:^{
   }];

}
