從xcode斷開連接後，應用程序行爲發生變化

我正在開發我的應用程序的新版本，並遇到了一個非常令人沮喪的問題。我有一些代碼，在旋轉後在屏幕上重新定位視圖（見下面的代碼）當我在模擬器中運行它時沒有問題，當我在物理設備上測試時，也沒有問題，直到我從xCode斷開連接。從Xcode斷開連接後，視圖不再正確定位。如果我重新連接到Xcode並再次運行它仍然不會像以前/預期的那樣工作。我添加了代碼中看到的日誌記錄，現在知道在第一次執行時高度和日誌都正確記錄，但是在斷開連接後它們被反轉。我還爲兩個不同的設備安裝了adhoc發行版，並在第一次執行時再次正常工作（這次沒有Xcode連接）。但是如果我在下一次執行中完全關閉應用程序（雙擊home並擦除），我們將獲得與之前完全相同的結果，並重新定位屏幕（假定NSlog值將再次顛倒）。我搜索了高和低，根本找不到任何解決方案。從xcode斷開連接後，應用程序行爲發生變化

該死的，這麼多的代碼？ –

對於長碼感到遺憾，但我不想錯過任何東西。 – joffd

老實說，你在做什麼是完全錯誤的...你應該考慮使用自動佈局... –

Fahim的建議後，我做了一些關於自動佈局的研究，並因此設法使用自動佈局來實現修復。我已經爲父視圖頂部和頂部的註釋視圖的距離設置了一個約束，並使用下面的代碼簡單地改變常量值，以便在屏幕上和離開屏幕的位置爲視圖設置動畫效果。因此我不再需要視圖旋轉中的問題中的任何代碼。雖然我沒有找到答案，爲什麼當手機與Xcode斷開連接時行爲會發生變化，不再是自動佈局執行所有工作的問題。

要動畫在屏幕上查看我使用：

[UIView animateWithDuration:0.5 animations:^{ 

       self.CommentViewOffset.constant = 40; 
       [self.view layoutIfNeeded]; 
     }];

和關閉屏幕，我使用：

UIDeviceOrientation orientation = [[UIDevice currentDevice] orientation]; 
[UIView animateWithDuration:0.5 animations:^{ 

    if (UIDeviceOrientationIsPortrait(orientation)==YES){ 
    self.CommentViewOffset.constant = 750.0; 
    self.editComentViewOffset.constant = 750; 
    [self.view layoutIfNeeded]; 

    }else if (UIDeviceOrientationIsLandscape(orientation)==YES){ 
    self.CommentViewOffset.constant = 440; 
    self.editComentViewOffset.constant = 440; 
       [self.view layoutIfNeeded]; 
    }

現在我有沒有必要在deviceOrientationDidChangeNotification方法做任何事情的一切都被處理與自動佈局。我必須說我到現在爲止完全避免了自動佈局，並且真希望我已經花時間做了更早的研究。
