How to Disable NSScrollView Scrolling

Unlike UIScrollView on iOS, NSScrollView on Mac does not have a handy scrollEnabled property for you to set to NO if you need to temporarily disable scrolling in your app.

If you Google around, you can find several posts on websites like stackoverflow that ask questions like How can I disable the vertical scrolling of a NSScrollView? Some have suggested setting the hasVerticalScroller property to NO as the answer. However, the hasVerticalScroller property only effects the visibility of the scroller, a value of NO does not actually prevent scrolling.

There are also ways to constrain scrolling from an NSView subclass, as described in Apple’s documentation here. Constraining scrolling from a view subclass can be useful, but what if you want to just temporarily disable scrolling?

The easiest way to disable scrolling it seems is to subclass NSScrollView and add a BOOL property with a name like scrollingEnabled. Then you can simply override the designated initializers (initWithFrame: and initWithCoder:) and set the ivar of the property to YES as the default value:

-(instancetype)initWithFrame:(NSRect)frameRect 
{ 
   self = [super initWithFrame:frameRect]; 
   if (self) 
   { 
       [self setUpOnInit]; 
   } 
   return self; 
}
 
- (instancetype)initWithCoder:(NSCoder *)coder 
{ 
    self = [super initWithCoder:coder]; 
    if (self) 
    { 
         [self setUpOnInit]; 
    } 
    return self; 
}
 
-(void)setUpOnInit
{
   //Set all default values. 
   _scrollingEnabled = YES; 
}

Now you can just override the scrollWheel: method and check the property:

-(void)scrollWheel:(NSEvent *)theEvent 
{ 
    if (self.scrollingEnabled) {  
      [super scrollWheel:theEvent];  
     } 
    else {  
       //scrolling is disabled. 
    } 
}

This technique will work in most cases, but there may be times when a view inside of a scroll view implements autoscrolling behavior (perhaps if the view is a dragging destination). If you need to temporarily disable scrolling in such a case, you should also subclass NSClipView and block scrolling by overriding the -constrainBoundsRect: method like this:

-(NSRect)constrainBoundsRect:(NSRect)proposedBounds
{
    MyScrollViewSubclass *mainScrollView = (MyScrollViewSubclass*)self.superview;
 
    if (mainScrollView.scrollingEnabled)
    {
        return [super constrainBoundsRect:proposedBounds];
    }
    else
    {
        //Disabled
        return self.documentVisibleRect;
    }
}

Tutorial: How to Redeem a Promo Code for a Free Download on the Mac App Store

Sometimes, Mac developers are kind enough to give promo codes out so people can download a copy of their paid applications for free. A promo code is simply a combination of characters you can use on the Mac App Store to get the app for free, but how do you use them? It’s easy. First, open up the Mac App Store application. After the window has finished loading, you will see to your right a link that says Redeem. Click it.

After you click the link a sheet will pop up asking you to log in with your Apple ID to redeem your code, so go ahead and log in!

After you log in, you will be brought to a screen with a title that says “Redeem Code”. At the bottom, you will see a text field where you can enter your redeem code. Enter it and the application will start downloading! That’s it!

How to Deprecate your Own API in Objective-C

To mark some of your own API as deprecated in Objective-C, you simply can add the following attribute to your method declaration (as seen in the snippet below):

-(void)myOldMethod __attribute((deprecated("Use the myNewMethod instead.")));

Now when you call myOldMethod in your code, the compiler will warn you that: “myOldMethod is deprecated. Use the myNewMethod instead”. You can also add the deprecated attribute to property declarations.

But what if you wanted to be more specific? For instance, if there is a better way to handle something in the iOS 8 SDK, you can mark an old method as deprecated only for projects that have iOS 8.0 or later as the deployment target.

-(void)myOldMethod NS_DEPRECATED_IOS(3_0, 8_0,"Use myNewMethod instead.");

Using the code snippet above, if you call myOldMethod the compiler will only warn you that the method is deprecated if your project’s deployment target is set to iOS 8 or later.

Deprecating your own methods can come in handy especially if you have written your own framework that is used across multiple projects. You may choose to deprecate some of your own API rather than removing the methods entirely until you get around to modifying your existing projects to use your new API.
