I have a simple OS X project ( in swift 2.0 and Xcode 7.0) and that is
supposed to open a .txt file and display the file’s contents in a document
window. For the most part, it works correctly, except that
windowControllerDidLoadNib is called twice each time I chose OpenFile from the
file menu. This results in the contents of the file being displayed in my
document window twice in succession. The code is very similar to an
objective-c project, which doesn’t do this, and I can’t see why this is
happening. Here’s an abbreviated version of windowControllerDidLoadNib:
override func windowControllerDidLoadNib(mySharedDocumentController:
NSWindowController) {
let myTextView: NSTextView = (self.TextView) as NSTextView
let theWindow: NSWindow = myTextView.window! // NSTextView inherits
from NSView, which can return a window
// the next 2 lines are simply to test getting the name of the window;
this is done correctly
let theName: NSString? = theWindow.title
print(“now at the top of windowControllerDidLoadNib \(theName)")
scrollview.documentView = myTextView
theWindow.contentView = scrollview
theWindow.makeKeyAndOrderFront(nil)
theWindow.makeFirstResponder(TextView)
print("\n we are at the end of windowControllerDidLoadNib")
updateView() // the code of updateView has nothing to do with the
problem; when it’s commented out, “now at the top of
windowControllerDidLoadNib” still gets show twice
}
Any suggestions why this might be happening would be greatly appreciated.
