這是我的實現,當然我已經初始化了頭文件中的所有屬性和插座。我是Xcode和Obj-c編程的新手,並嘗試在iOS5模擬器上播放此視頻,該視頻不工作。任何幫助或指針將不勝感激。無法使用XML解析器呈現視頻

無論哪種方式..我似乎得到一個程序在我的主線程收到SIGABRT消息...調試器不會說太多...但我想知道是否有這一行的錯誤code(VideoMainViewController *)initWithXML {self.videoArray = [NSMutableArray arrayWithCapacity:0]; – irookie
謝謝,我做了一個堆棧跟蹤,它指向的路線如下。雖然我不知道錯誤可能是什麼。 '[self.view addSubview:thumbView];' – irookie
嘗試將其更改爲'self.videoArray = [NSMutableArray array];'。無論如何,沒有真正的需要啓動容量。 – chown
