我的自定義類對象即使在保留後也會被釋放

我一直在試圖調試這個錯誤，就像幾天一樣，似乎仍然無法理解我的對象究竟在做什麼。代碼如下所示。 - （BOOL）web視圖：（的UIWebView *）webView的shouldStartLoadWithRequest：（的NSURLRequest *）請求navigationType：（UIWebViewNavigationType）navigationType {從點擊鏈接 //提取數據我的自定義類對象即使在保留後也會被釋放

SongObject *數據= [[SongObject的alloc] INIT]; [數據保留]; selectedSong = Data; }

selectedSong是主類中的公共變量，現在瘋狂的事情是使用上述方法在其他地方工作，但是使用了shoulStartLoadWithRequest。

試圖解除它給我「超出範圍」，可能是因爲一些瘋狂的原因，「shouldStartLoadWithRequest」會自動釋放我的對象，即使我說不要？

任何想法的？

編輯：這是H和M文件，其中選擇宋被認爲是舉行。
