INAppStoreWindow

Title
bar and traffic light customization for NSWindow

INAppStoreWindow

is
an NSWindow subclass that was originally developed to mimic the appearance of the main window in the Mac App Store application introduced in OS X 10.6.6.

The MAS application has since transitioned away from this design, but

INAppStoreWindow

is
still being actively developed to provide extensive additional customization options for

NSWindow

title
bars.





Features of INAppStoreWindow:

No private API usage and Mac App Store friendly.
Fully customizable title bar view -- add subviews (toolbars, buttons, etc.) and block based drawing for custom backgrounds
Adjustable title bar height
Customization of the traffic light/fullscreen buttons for all button states.
Customization of the window title text.
Works on OS X versions 10.6-10.9
Compatible with full screen mode in OS X 10.7+

All
of these great apps are using INAppStoreWindow in production!

Usage

ARC

INAppStoreWindow

now
requires ARC to compile. If your project does not use ARC, compile

INAppStoreWindow.m

with
the

-fobjc-arc

linker
flag.

Basic
Configuration

Using

INAppStoreWindow

is
as easy as changing the class of the

NSWindow

in
Interface Builder, or simply by creating an instance of

INAppStoreWindow

in
code (if you're doing it programmatically). I've included a sample project demonstrating how to use

INAppStoreWindow

.

NOTE: The title bar height is set to the standard window title height by default. You must set the 'titleBarHeight' property in order to increase the height of the title bar.

Some people seem to be having an issue where the title bar height property is not set properly when calling the method on an NSWindow without typecasting it to the INAppStoreWindow class. If you are experiencing this issue, do something like this (using a window
controller, for example):

INAppStoreWindow *aWindow = (INAppStoreWindow*)[windowController window];
aWindow.titleBarHeight = 60.0;

Adding
buttons and other controls to the title bar

Adding controls and other views to the title bar is simple. This can be done either programmatically or through Interface Builder. Here are examples of both methods:

Programmatically

// This code places a 100x100 button in the center of the title bar view
NSView *titleBarView = self.window.titleBarView;
NSSize buttonSize = NSMakeSize(100.f, 100.f);
NSRect buttonFrame = NSMakeRect(NSMidX(titleBarView.bounds) - (buttonSize.width / 2.f), NSMidY(titleBarView.bounds) - (buttonSize.height / 2.f), buttonSize.width, buttonSize.height);
NSButton *button = [[NSButton alloc] initWithFrame:buttonFrame];
[button setTitle:@"A Button"];
[titleBarView addSubview:button];

Interface Builder

NOTE: Even though the content layout for the title bar can be done in Interface Builder, you still need to use the below code to display the view created in IB in the title bar.

// self.titleView is a an IBOutlet to an NSView that has been configured in IB with everything you want in the title bar
self.titleView.frame = self.window.titleBarView.bounds;
self.titleView.autoresizingMask = NSViewWidthSizable | NSViewHeightSizable;
[self.window.titleBarView addSubview:self.titleView];

Centering
the traffic light and full screen buttons

The vertical centering of the traffic light and full screen buttons can be controlled through two properties:

centerTrafficLightButtons

and

centerFullScreenButton

.

The traffic light buttons are vertically centered by default.

Hiding
the title bar in fullscreen

You can tell INAppStoreWindow to hide when entering fullscreen mode, and reappear on exit. Just set the property

hideTitleBarInFullScreen

in
order to hide it.

Padding
the traffic lights and fullscreen buttons

The left padding of the traffic lights can be adjusted with

trafficLightButtonsLeftMargin

and
the right padding of the fullscreen button can be adjusted with

fullScreenButtonRightMargin

.

Hiding
the baseline (divider line between the titlebar and the content view)

The baseline divider can be hidden by setting

showsBaselineSeparator

to

NO

,
the default value is

YES

.

Customizing
traffic lights buttons

In order to customize these buttons, you would use

INWindowButton

class.
You must create a separate instance for each button and provide your graphics for each state of the button. Currently the following states are supported:

Active
Active in not main window
Inactive (disabled)
Rollover
Pressed

Please refer to

INWindowButton.h

header
documentation for more details.

Customizing
window's title appearance

You can enable title drawing by setting

showsTitle

property
to

YES

.
For NSDocument based apps, you can enable drawing the document proxy icon by setting

showsDocumentProxyIcon

property
to

YES

.
You can adjust appearance using

titleTextColor

,

inactiveTitleTextColor

,

titleTextShadow

,
and

inactiveTitleTextShadow

properties.
Also, you can enable title drawing in fullscreen by setting

showsTitleInFullscreen

property
to

YES

.

Using
your own drawing code

A lot of time and effort has gone into making the custom titlebar in INAppStoreWindow function just right, it would be a shame to have to re-implement all this work just to draw your own custom title bar. So INAppStoreWindow has a

titleBarDrawingBlock

property
that can be set to a block containing your own drawing code!

[self.window setTitleBarDrawingBlock:^(BOOL drawsAsMainWindow, CGRect drawingRect, CGPathRef clippingPath){
// Custom drawing code!
}];

This block gets passed some useful parameters like if the window is the main one(

drawsAsMainWindow

),
the drawing rect of the title bar(

drawingRect

),
and a pre-made clipping path with rounded corners at the top(

clippingPath

).

Setting
the title bar colors

If you just want to adjust the color of the title bar without drawing the whole thing yourself, there are a few properties to help you do so:

self.window.titleBarStartColor     = [NSColor colorWithCalibratedWhite: 0.6 alpha: 1.0];
self.window.titleBarEndColor       = [NSColor colorWithCalibratedWhite: 0.9 alpha: 1.0];
self.window.baselineSeparatorColor = [NSColor colorWithCalibratedWhite: 0.2 alpha: 1.0];

self.window.inactiveTitleBarEndColor       = [NSColor colorWithCalibratedWhite: 0.95 alpha: 1.0];
self.window.inactiveTitleBarStartColor     = [NSColor colorWithCalibratedWhite: 0.8  alpha: 1.0];
self.window.inactiveBaselineSeparatorColor = [NSColor colorWithCalibratedWhite: 0.4  alpha: 1.0];

Extensions

Additional extensions for

INAppStoreWindow

are
provided in the Extensions folder.

NSDocument+INAppStoreWindowFixes

Add this category to your project to fix title bar layout for document based apps in response to

-[NSDocument
updateChangeCount:]

. This fix was separated from the main

INAppStoreWindow

codebase
because it swizzles methods on

NSDocument

.

INTitlebarView+CoreUIRendering

Add this category to your project to use CoreUI to render the system default title bar gradient, noise texture, and baseline separator. This will provide the most accurate visual results. You should only add this category to your project
if you intend to release outside the App Store!

If you use this category you must define the preprocessor symbol

INAPPSTOREWINDOW_NO_COREUI

with
a value of 1 in the build configuration for your Mac App Store version in order to exclude this code because ituses private APIs and will result in rejection if included in a Mac App Store submission.

When CoreUI rendering is not available, INAppStoreWindow will emulate the rendering of the system title bar as closely as possible.
