Building xCode project and generating IPA file using Ant

Following is the procedure to generate IPA file.

Under “project settings” change “derived data location” to “project-relative”, and make it "DerivedData/dist/". If you want any other location, change the same in the code. This will be the location where ".app" file and all other project info is stored.

Set the values to the fields in CAPITAL LETTERS, and save the file as build.xml

-----------------------------------------------

<project default="buildAndPackage" basedir="." name="APP-FOLDER">
<property name="local.projectPath" location="WHERE THE PROJECT IS LOCATED" />
<property name="local.ipaPath" location="WHERE TO SAVE THE IPA FILE" />

<property name="app.id" value="APP-ID" />
<property name="scheme" value="APP-SCHEME(MOSTLY APP-ID)" />
<property name="version" value="VERSION-NO" />
<property name="distributorName" value="NAME USED IN IOS PROVISIONING PORTAL" />

<property name="ProvisioningProfile" location="WHERE YOU KEPT THE FILE" />
<property name="configuration" value="Release/debug/AdHocDistribution/AppStore SELECT THE APPROPRIATE" />

<target name="buildAndPackage">
<exec executable="/Developer/usr/bin/xcodebuild">
<arg value="-project" />
<arg value="${local.projectPath}/${app.id}.xcodeproj" />
<arg value="-scheme" />
<arg value="${scheme}" />
<arg value="-configuration" />
<arg value="${configuration}" />
<arg value="clean" />
<arg value="build" />
</exec>

<exec executable="xcrun">
<arg value="-sdk" />
<arg value="iphoneos" />
<arg value="PackageApplication" />
<arg value="-v" />
<arg value="${local.projectPath}/DerivedData/dist/Products/${configuration}-iphoneos/${app.id}.app" />
<arg value="-o" />
<arg value="${local.ipaPath}/${app.id}-${version}.ipa" />
<arg value="--sign" />
<arg value="iPhone Distribution: ${distributorName}" />
<arg value="--embed" />
<arg value="${ProvisioningProfile}" />
</exec>
</target>
</project>

--------------------------------

Then run it from command line by typing "ant"

Ubuntu: Access a usb flash drive from the terminal

1. Find what the drive is called You'll need to know what the drive is called to mount it. To do that fire off: sudo fdisk -l You're looking for a partition that should look something like: /dev/sdb1 . Remember what it's called. 2. Create a mount point Create a new directory in /media so you can mount the drive onto the filesystem: sudo mkdir /media/usb 3. Mount! sudo mount /dev/sdb1 /media/usb When you're done, just fire off: sudo umount /media/usb Source: StackOverflow

Java: Use BigInteger in for-loop

In my previous post , I mentioned a way to handle large integers by using BigInteger. Now I'm going to provide a very important usage of it. We often use for-loop. So here is the way to use it: Ordinary integers: for(int i = 1; i <= n; i++) { //Task to do } BigInteger: for (BigInteger bi = BigInteger.valueOf(1); bi.compareTo(n) <= 0; bi = bi.add(BigInteger.ONE)) { //Task to do } here n is a BigInteger variable.

Karabiner: Mouse/keyboard customizer for OS X

For beginners, or the one who migrated from Windows environment, Natural Gestures (Scrolling and Swiping) might be bit confusing. But, once you get familiarized with them, it may feel like "What was I doing, all those days?". It all changed, when I connected external mouse to my Macbook. When you start using that WHEEL, you will be confused. Luckily there is a setting for mouse, to change scroll behavior (natural or the other way). But, here's the catch. If you toggle that setting, it also toggles the same for TRACKPAD!!!!! I've seen that many people were freaked out and even raised BUG report to Apple. But, all those reports were closed, saying that is not a bug, but intentional feature!!! For those, who can't leave with such one-sided settings, here is a simple util, which came to my rescue: Karabiner It's simple, powerful and stable mouse/keyboard customizer for OSX. Without going into much detail, here's the configuration I used to ret
