Re: BOOL parameter passed as nil object

I believe that a BOOL can only be YES or NO. A nil value on a BOOL would be NO if I am correct. Am I correct here? On Apr 18, 2016, at 9:56 PM, Carl Hoefs wrote: > Suppose I have an object with a declared method signature: > -(void)myMethod:(BOOL)a_bool; > > Q1: If I invoke it like this: >

Re: Proper way to set up constants when building an iOS framework

Another thing I do is add FOUNDATION_EXPORT before my constants in headers, which will give you the right stuff whether C or C++; C++ name mangling is a common reason for odd link errors if you include a header in a C++/Objective-C++ source file. I'm sure you can find examples of this in open s

In a Terminal window, start off with this command: find /Applications/Xcode.app/Contents/Developer/Platforms -type f -print0 | xargs -0 grep FOUNDATION_EXPORT Then go to opensource.apple.com and look around. Note those are zeros, not capital O's if you type the command out vs copy/paste. -- Gar

How to make an app launch on login?

One of my companies’ apps has a “Launch at login” pref, which no longer works in OS X 10.11. I’m not surprised, since the existing code implements this by writing into loginwindow’s user defaults :-p I’m trying to find the currently supported API for this. The “Adding Login Items” page says: >

Re: How to make an app launch on login?

There was some discussion of this on stack overflow but one of the APIs there is deprecated: LSSharedFileListItemResolve. It’s 3rd parameter takes a pointer to a CFURLRef and that is now deprecated. Instead, use LSSharedFileListItemCopyResolveURL; basically the return value from this is what you

I spoke too soon; yes, all of this is marked as “available but deprecated on 10.11”. I would hope that Apple would provide sample code to show the preferred new way to do this. > On Apr 19, 2016, at 2:29 PM, Jeff Szuhay wrote: > > There was some discussion of this on stack overflow but one
