动画UIViewController的框架

Question

我正在尝试制作动画。当我单击图像时，视图会将UIViewController从navigationController的视图扩展到整个屏幕的边界，然后将其推到// Code in the controller which pushes the controller on the stack self.navigationController.view.center = center; self.navigationController.view.frame = frame; self.navigationController.view.transform = CGAffineTransformMakeScale(0.1f, 0.1f); // Code in the viewDidAppear of controller being pushed to the stack [UIView animateWithDuration:0.5 delay:0.0 options:UIViewAnimationOptionCurveEaseOut animations:^{ self.navigationController.view.transform = CGAffineTransformIdentity; self.navigationController.view.frame = [[UIScreen mainScreen] bounds]; self.navigationController.view.center = CGPointMake(self.view.frame.size.width/2, self.view.frame.size.height/2); } completion:nil]; 上并缩小到相同的大小，同时将其弹回。我能够创建推送动画，但在尝试创建弹出动画时失败了。

viewDidDisappear

这项工作正常，但我在initialFrame中尝试使用以下代码进行流行动画，其中UIViewController是我点击以打开// Code for viewDidDisappear [UIView animateWithDuration:0.5 delay:0.0 options:UIViewAnimationOptionCurveEaseOut animations:^{ self.view.transform = CGAffineTransformMakeScale(0.1f, 0.1f); self.view.frame = self.initialFrame; self.view.center = CGPointMake(self.initialFrame.size.width/2 + self.initialFrame.origin.x, self.initialFrame.size.height/2 + self.initialFrame.origin.y);} completion:nil]; 的框架。

function add() {
    // just in case someone will try to run the function without arguments
    if (!arguments.length) {
        throw new Error("add(): Function call with no arguments.");
    } 

    // final return
    if (arguments.length === 1) {
        return arguments[0];
    }

    // removing first element from array and saving it in variable 'number'
    // we use Array.prototype.shift.apply() because 'arguments' is an array-like
    // object, and doesn't have shift() method
    var number = Array.prototype.shift.apply(arguments);

    // this is a bit hacky, adding number to the first element of 'arguments'
    arguments[0] += number;

    // recursively calling function with new arguments
    return add.apply(this, arguments);
}

add(1, 2, 3, 4, 5);

我无法使pop动画生效。请帮帮我。
