Mount the Xcode 3.2.6 DMG and open Terminal

Enter commands:

sh-3.2# export COMMAND_LINE_INSTALL=1
sh-3.2# open /Volumes/Xcode\ and\ iOS\ SDK/Xcode\ and\ iOS\ SDK.mpkg/

You are now able to install Xcode 3.2.6 on Lion with no package modifications!

If the installer dialog while stage “Updating files…” show you this dialog:

In order to continue installation, please close the following application:
iTunes

but you think that have no iTunes opened, open Activity Monitor (located in Applications/Utilities),

Start typing “iTunes” into the filter box in the top right
Select iTunesHelper from the list and click the Quit Process button.

Don’t work?
Try second method:

- Download the Xcode 3.2.6 disk image, ‘xcode_3.2.6_and_ios_sdk_4.3.dmg’, (I will assume it’s in ~/Downloads for the next steps).

- Open up the Terminal and change to the directory where the image resides:

- Attach the disk image with a shadow image to make it writable. Terminal command (as one line):

-Remove the string ‘&& system.compareVersions(my.target.systemVersion.ProductVersion, ’10.7′) < 0 ‘ from line 148 in ‘Xcode and iOS SDK.mpkg/Contents/iPhoneSDKSL.dist’. Assuming the disk image got mounted at ‘/Volumes/Xcode and iOS SDK’, you can use this one-liner:

Install Xcode!

done.

Today a simple tutorial to show a right click context menu on a selection on web pages with Chrome Browser!

This:

First of all you need to read chrome developer reference (http://goo.gl/ND5z2) .

You can start reading from manifest files format (manifest.json):

After that, open notepad and create 3 files in a folder:
- manifest.json
- rightclick.js
- background.html
and an optional icon file
- icon.png (http://goo.gl/3kK92)

In manifest.json copy/paste this code:

In background.html copy this string:

In rightclick.js write:

Yeah!!

You can change serviceCall url with any search string you want like:
Google -> ‘http://www.google.com/q=’ + selectedText;
Facebook -> https://www.facebook.com/search/results.php?q=’ + selectedText;
Bing -> http://it.bing.com/search?q=’ + selectedText;
etc… etc…

Now,
open Google Chrome -> Tool -> Extensions -> Load unpacked extension.

Done!

Select a text in any page and click to see result!

enjoy!

29 Km/h. great job!

Hi nerdz,
today i’ll show you how to easily control remotely your room with a stupid motion detector, a piro sensor (or you can use other sensors, like ultrasonic, infrared, light sensor, pressure, etc etc…) and two lines of PHP code and C.

* Useful if you want to know if anyone enter in your room and the time that remains there! *

You can get this sensor from AirWick deo!

How it works?
Your piro sensor, when detect a motion, notify arduino, that was programmed to send to serial port a value (“m” or “n”).
These value are interpreted by a serial reader (c# program, objective-c, java, c++, or somethig else) that call a PHP page that send email if is enabled sending mode.
Second php page, permit you to control arduino (enable/disable/show logs/clear all).

Steps:
Connect your piro sensor to arduino, easy way, like this:

After that, write your simple arduino code:

Hi all!
By chance i founded this tricks that permit to show a “Dictionary definition” for the selected word in a UITextField on a hidden menu.

Menu contains these actions:

It’s a cool tricks, that show an hidden menu with a lot of options, that i never see before!

Watch this:

And this is the dictionary definition for pizza on simulator:

How?

Follow these simple steps, and after 1 minutes you’ll print your code generated pdf from your iphone!

Now, implement all methods in your class…

Continue reading “[Objective-C] Print code generated PDF with AirPrint” »

Suppose that we have a ViewController.h and .m like this:

And a class called SetValue, with two methods.

What is the value printed by the NSLog?

enjoy.
