你好，下面方式， alert不能弹出，还会造成界面卡死
SPAlertController *alertController = [SPAlertController alertControllerWithTitle:@"请选择变更的场景，变更后报警规则将重置" message:@"subtile" preferredStyle:SPAlertControllerStyleActionSheet animationType:SPAlertAnimationTypeFromBottom];
SPAlertAction *new = [SPAlertAction actionWithTitle:@"+ 新建场景" style:SPAlertActionStyleDestructive handler:^(SPAlertAction * _Nonnull action) {
NSLog(@"点击了 新建场景");
}];
SPAlertAction *cancel = [SPAlertAction actionWithTitle:@"取消" style:SPAlertActionStyleCancel handler:^(SPAlertAction * _Nonnull action) {
NSLog(@"点击了Cancel");
}];
[alertController addAction:new];
[alertController addAction:cancel];
[alertController setBackgroundViewAppearanceStyle:appearanceStyle alpha:0.5];
你好，请问是在什么情况下弹出来的，我复制你的代码在我的demo里弹出来是没问题的
