PathforResource與一個.ics文件問題，目標C

Question

我剛剛在Objective C中學習編程，而且我從一個.ics文件中獲取信息出現在我的tableview中。

該tableview工作正常。我試過將信息直接存儲到NSArray中。點擊標題時，我會看到詳細的信息視圖。

當我試圖從.ics文件中獲取信息時，我甚至不會顯示標題。我只是得到一個空的窗口。

我猜你的問題是這樣的：

NSString *path = [[NSBundle mainBundle] pathForResource:@"timeedit" ofType:@"ics"]; 
NSDictionary *dict = [NSDictionary dictionaryWithObject: path forKey:@"Calendar app"]; 

iCal文件（的.ics）是不是在屬性列表格式，這意味着本應返回nil的XML文件。你應該找到一種不同的方式來閱讀iCal文件。
