Ios 禁用重新拍摄、播放和使用视频屏幕UIImagePickerController

我只想听到一声尖叫： 使用

UIImagePickerController

时，它使用两个屏幕

但我不想要这个：

这是可能的吗？

如果您在发布问题之前已经检查了UIImagePickerController的文档，那么您可以使用

AVFoundation

库构建您自己的相机控制器，以及您想要的任何控件和屏幕。祝你好运

@Fahri

是正确的

AVFoundation

更灵活，但是如果您想坚持使用

UIImagePickerController

，您可以通过将

showsCameraControls

属性设置为

NO

来关闭相机控件，然后展示您自己的视图和自定义方法

将代码更改为：

拍摄视频

- (IBAction)takeVideo:(UIButton *)sender {

    UIToolbar *toolBar=[[UIToolbar alloc] initWithFrame:CGRectMake(0, self.view.frame.size.height-54, self.view.frame.size.width, 55)];

对不起，我认为可能有一个简单的方法来完成这项任务。是的，对不起，我忘记了：）这可能是完成任务的更快的方法，@Maximilian.Hey@meda我对“picker”有问题，我需要在头文件中放什么对不起？@Maximilian你必须在类级别声明它，请看我的编辑我为您下载了一个演示项目您如何处理“FinishedPickingMedia”？
