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

请向我建议任何可以禁用IOS中屏幕截图的工作包或任何本机代码。

这是库React Native Prevent截图的解决方案之一：，请查看链接RN-screenshot

通过将 2 两个添加到 appDelegate.m 中来覆盖屏幕

- (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];
}];
}
