ios - 自定义过渡动画显示 viewController 并闪烁

Question

我正在使用自定义过渡动画，如推送动画。但是当我在我的 viewcontroller 加载完动画后使用这段代码时，它只是闪烁。

这是我用来展示我的 View Controller 的方法

+(void)leftpresentFrom:(UIViewController *)fromviewcontroller
                To:(UIViewController *)toviewcontroller
{

CGPoint newcenter       = CGPointMake(480, toviewcontroller.view.center.y);


toviewcontroller.view.center           =newcenter;


toviewcontroller.view.clipsToBounds=YES;


[fromviewcontroller.view addSubview:toviewcontroller.view];


[UIView animateWithDuration:.5
                      delay:0.0
                    options:UIViewAnimationOptionCurveEaseInOut
                 animations:^{
                     toviewcontroller.view.center = CGPointMake(160 ,toviewcontroller.view.center.y);
                 }
                 completion:^(BOOL finished){
                     [toviewcontroller.view removeFromSuperview];
                     [fromviewcontroller presentViewController:toviewcontroller animated:NO completion:^{

                     }];

                 }];
}

您是否尝试在新 Controller 出现后删除 View ？

例如。

[fromviewcontroller presentViewController:toviewcontroller animated:NO completion:^{
    [toviewcontroller.view removeFromSuperview];
}];
