What difference exist from where a method will be called?

Dear all, there is a thing i can’t understand. In my class I have an NSMutableArray as a instance variable and a property. With the init method the array will be created with alloc / init. When my tableView has rows an information for each row will be added as object to my array. Then I have

C callbacks with NSNotificationCenter?

As a C programmer I'm trying to avoid Objective C whenever and wherever possible. The good thing is that I can do most interaction with Cocoa from normal C functions. I only had to write very few classes. Most of the Cocoa stuff can be done from normal C functions just fine. Now I'd like to

I have a Time Capsule and find it very unreliable. It simply won’t stay mounted as a Time Machine volume. I would never save a file directly to it. Can you not save the original locally and then sync with the Time Capsule? On Wed, Sep 7, 2016 at 3:56 AM, Peter Hudson wrote:

Multiple Inheritance via protocol extensions in Swift
