[TIP] XCode Header Search Path

For many of you, this sounds like a stupid thing. But for those that just use gcc -I from command line, can be a pain find how to do it.

So, the problem is. How can I specify my Include path in XCode (gcc -I./mypath).

Tap on your project target, and click “Get Info“, tap on “Build” tab and search “Path” as showed in the figure above. Then click on the “Header Search Paths” options and add your favorite include paths for selected target.

iPhone: Touch, Drag, Hit!

Yesterday, Fredrik has asked me something like “Drag & Drop with Hit Test” on the iPhone. Here’s a simple example.  There’s a simple UIView class that handles the touch events and a protocol that says that if the “DragMe View” has hit or not the “HitMe View”. Below you can see the result and the Source Code Link.

The source code is available here: Touch, Drag, Hit Source Code.

Qt/Cocoa DataStream (Binary Communication)

In a time of REST protocols… I still love the Binary Communication. I don’t have much ideas this period, I need to find a different job (C# doesn’t fit my code necessity). The Example Source code, contains two Folder. One is the Qt4 TcpServer the second one is the ugly application that you can see below

Note: This example doesn’t have anything related to the Qt 4.5 Cocoa Support.

Run the Qt4 Server, and the Cocoa Application (Remember to change the SERVER_HOST in AppController.m) and try to send some binary data. The Qt Server will receive this data it will resend you. Protocol is Very easy 1 byte of Data Type (Int8, Int16, ..) and Data. Remember that Intel arch is Little Endian.

Note: This is just a “Draft” a “non complete” example only to give the idea on how it works.

The Source Code is available here: Qt/Cocoa DataStream Source Code.

Cocoa: Sidebar with Badges, Take 2

Do you remember the Cocoa Sidebar? No, Take a Look at this post Cocoa Sidebar with Badges.

Joel asked me to revise the Sidebar, allowing to add/remove and do other operation at any time.

I’ve rewritten all the code of the Sidebar, and I’ve added a couple of new features, like the default action handler and obviously the ability to add, remove items and badges at any time.

All the past features, like Drag & Drop are still present, but there’s something else to do to improve it. If You’ve suggestions, patches or something else post a comment or send me a mail!

You can Find the Source Code Here: Cocoa Google Maps.

Last iPhoto ‘09 presented at MacWorld contains a couple of interesting Features: Faces and Places. Today, I’ve a little bit of free time to play with my Mac, and the topic is How to embed Google StreetView into a Cocoa Application.

The Solution is using WebKit and Google Maps API. We’ve a simple HTML file that contains StreetView “Canvas” and a couple of javascript methods that interact with GStreetviewPanorama Object.
