如何在 react-native 中防止 iOS 截图

Question

在我的应用程序中，我想在 React-native 中禁用 IOS 的屏幕截图功能。

请建议我任何可以在 IOS 中禁用屏幕截图的工作包或任何本机代码。

这是库反应原生阻止截图的解决方案之一：，查看链接rn-screenshot

通过在 appDelegate.m 中添加 2 两个来覆盖屏幕

- (void)applicationWillResignActive:(UIApplication *)application {

// fill screen with our own colour
UIView *colourView = [[UIView alloc]initWithFrame:self.window.frame];
colourView.backgroundColor = [UIColor whiteColor];
colourView.tag = 1234;
colourView.alpha = 0;
[self.window addSubview:colourView];
[self.window bringSubviewToFront:colourView];

// fade in the view
[UIView animateWithDuration:0.5 animations:^{
  colourView.alpha = 1;
}];
}

- (void)applicationDidBecomeActive:(UIApplication \*)application {
// grab a reference to our coloured view
UIView \*colourView = [self.window viewWithTag:1234];
// fade away colour view from main view
[UIView animateWithDuration:0.5 animations:^{
colourView.alpha = 0;
} completion:^(BOOL finished) {
// remove when finished fading
[colourView removeFromSuperview];
}];
}
