为了制作我的自定义UIImagePickerSourceTypeCamera
,我必须这样做:
pickerOne = [[UIImagePickerController alloc] init];
pickerOne.delegate = self;
pickerOne.sourceType = UIImagePickerControllerSourceTypeCamera;
pickerOne.showsCameraControls = NO;
pickerOne.navigationBarHidden = YES;
pickerOne.toolbarHidden = YES;
pickerOne.wantsFullScreenLayout = YES;
但现在,当我拍这样的照片时:
[cameraButton addTarget:pickerOne
action:@selector(takePicture)
forControlEvents:UIControlEventTouchUpInside];
拍摄照片时不显示快门。有没有办法以编程方式显示它?

有可能。诀窍是执行以下操作:
初始化拾取器时启用相机控件(这将启用快门视图)。
pickerOne.showsCameraControls = YES;
使用您自己的cameraButton
在takePicture:
方法中,执行以下操作:
pickerOne.showsCameraControls = NO;
[[NSRunLoop currentRunLoop] runUntilDate:[NSDate dateWithTimeIntervalSinceNow:0.0]];
[pickerOne takePicture];
在imagePickerController:didFinishPickingMediaWithInfo:
方法中执行以下操作:
pickerOne.showsCameraControls = YES; // perform on main thread

无法控制“快门”效果。但是,您可以创建自己的图像并在其中添加效果。
