Re: Accessing method from another class

Re: Accessing method from another class

I found your solution. In Application.m, at the end of the setSlim: method, add this line: [[NSApp delegate] resetTextAndBar:self]; And at the top of the file, import the BeastCloneAppDelegate.h file to suppress the warning. This will work since you are accessing a function set as NSApplicat

Field editor for custom tableview cells contains wrong string

Re: How to disable the table view when search bar is active

The -setScrollEnabled method does not show up in my documentation browser, so I'm not sure what it will do. However, whenever a view does not change as expected, invoke - display. In your case, [[self tableView] display] ; If it works, this may or may not be a correct fix for production
