Trouble refreshing UITableView
I'm trying to develop a basic GPA Calculator. I have an AllCourses class that holds Course objects.
I have an AllCourses object in my CalcAppDelegate.
In my ThirdViewController I can successfully update the number of Courses in my AllCourses object. However, 开发者_如何学JAVAthe problem I'm having is that when I switch to the RootViewController the UITable isn't being repopulated with the updated Courses that were added.
I tried [self reloadData] in the viewWillAppear in my RootViewController but it caused my app to close. I didn't use IB to create the views so I think it could be the case that I don't have things hooked up correctly. I did it programatically. Does anyone see anything I'm missing in my code?
Here is the link to my project http://files.me.com/aahrens/q0odzi
Try
[[self tableView] reloadData]
The method is implemented in UITableView
rather than in UITableViewController
, which is why your app crashed.
have you tried [self.tableView reloadData]
