我創建了一個ViewController，它通過JSON解析通過三個單獨的UIImageViews顯示三個圖像和其他信息。當您點擊任何圖像時，會將您帶到另一個ViewController，在後臺彈出UIScrollView，一個UIImageView鏈接到所有三個圖像和一個Button，將關閉彈出窗口ViewController並將其帶回前一個。這是一個screenshot。我遇到的問題是我添加了以下代碼：Xcode Swift：無法關閉彈出式菜單圖像
func removeZoom()
{
UIView.animateWithDuration(0.25, animations: {
self.view.transform = CGAffineTransformMakeScale(1.3, 1.3)
self.view.alpha = 0.0;
}, completion:{(finished : Bool) in
if (finished)
{
self.view.removeFromSuperview()
}
});
}
@IBAction func closeZoom(sender: AnyObject) {
self.navigationController?.popToRootViewControllerAnimated(true)
}
而當我嘗試點擊關閉按鈕時，什麼也沒有發生。不知道我錯過了什麼。任何指導都會有所幫助。
這裏我把代碼爲兩個控制器：

我會檢查出來，你應該只使用
因爲你提出那個視圖控制器，該
popToRootViewControllerAnimated(true)使用，看看是否有什麼東西我們缺失 – Loxx我現在看到的另一個問題可能是在視圖控制器底部的動畫中的這個「self.view.removeFromSuperview（）」，我不會從視圖中刪除任何東西，除非您先關閉頂部的POP導航堆棧或DISMISS它。通過任何我的意思是視圖控制器 – Loxx
對於我所看到的，他根本不使用'self.view.removeFromSuperview（）'，也許這是一種失敗的方法，但無論如何不要這樣做：P – dGambit
