iOS13 适配总结

1、iOS 13中 presentViewController 模态动画，跳转问题修复

iOS 13之前 presentViewController 跳转的 modalPresentationStyle 默认为 UIModalPresentationFullScreen ；

在iOS 13中默认 style 被改为 UIModalPresentationAutomatic，可参考苹果代码注释：

修改方案：

CLBaseWebViewController *webViewController = [[CLBaseWebViewController alloc] initWithURL:url type:type data:data];

UINavigationController *nav = [[UINavigationControlleralloc] initWithRootViewController:webViewController];

nav.modalPresentationStyle = UIModalPresentationFullScreen;

[self.navigationController presentViewController:nav animated:YES completion:nil];
