Help: NSScrollView is resizing its documentView down to (0, 0)

I haven't done much AppKit work in a while. Right now I have a small app where I'm trying to do something very simple: put a custom NSView in a window and make it scrollable. The view determines its own frame size based on the content it needs to display. So all I did was create a new window in

malloc(0) returns a pointer, not NULL

This came as news to me. The C spec says this is implementation-definited; malloc(0 may return either NULL or it may return a pointer that can subsequently be passed to free(). In the case of the bug I'm looking at just now, it's an error in my code, so I now have: assert( 0 != bytes ); ptr = ma

Re: Issues with implementing WYWIWYG font menu

Yes, this approach has worked much better. I see only two drawbacks. 1) The first time the menu is opened, it takes as much as two seconds for it to appear. This only seems to be true for the first instance of the menu that is opened. (It’s a popup menu in a document window, so different documen

Core Data sync between iOS and Mac apps

I'm looking into options for building an iOS and Mac app that can sync/share Core Data between them. I'm well aware of the issues with Core Data iCloud syncing in iOS 5 and 6 and that it is supposedly better so I'm willing to try it. The apps can have deployment targets of iOS 8 and greater and

We did this a few months ago When you embed in a scrollview you end up with NSScrollView NSClipView Your View Constrain the scrollview to something above it if it needs it, if it’s the whole window, probably doesn’t. Constrain the clipview to all 4 sides of the scrollview. Const

Re: Help: NSScrollView is resizing its documentView down to (0, 0)

If you have AutoLayout on in a window it's actually on for all views. NSScrollView and its hierarchy are a bit weird though. Thing to do is create height and width constraints for the document view and outlets for them so you can configure them. If you're using 10.10+ you can make them configu
