How to create iOS fat dynamic framework

“Fat” means that this framework has many slices. Each slice (machine code) is built for certain architecture. The fat framework we are going to build contains i386 x86_64 armv7 armv7s arm64.

  • armv7 is for iPhone 4s
  • armv7s is for iPhone 5
  • arm64 is for iPhone 6

Firstly we need to create a target for dynamic framework: Cocoa Touch Framework

Secondly we create a new target: External Build System

Go to Build Phases -> Run script

Paste the below code snippet in there


# make sure the output directory exists
# Step 1. Build Device and Simulator versions
xcodebuild -target "${PROJECT_NAME}" ONLY_ACTIVE_ARCH=NO -configuration ${CONFIGURATION} -sdk iphoneos BUILD_DIR="${BUILD_DIR}" BUILD_ROOT="${BUILD_ROOT}" clean build
xcodebuild -target "${PROJECT_NAME}" -configuration ${CONFIGURATION} -sdk iphonesimulator ONLY_ACTIVE_ARCH=NO BUILD_DIR="${BUILD_DIR}" BUILD_ROOT="${BUILD_ROOT}" clean build
# Step 2. Copy the framework structure (from iphoneos build) to the universal folder
# Step 4. Create universal binary file using lipo and place the combined executable in the copied framework directory
lipo -create -output "${UNIVERSAL_OUTPUTFOLDER}/${PROJECT_NAME}.framework/${PROJECT_NAME}" "${BUILD_DIR}/${CONFIGURATION}-iphonesimulator/${PROJECT_NAME}.framework/${PROJECT_NAME}" "${BUILD_DIR}/${CONFIGURATION}-iphoneos/${PROJECT_NAME}.framework/${PROJECT_NAME}"
# Step 5. Convenience step to copy the framework to desktop directory
ditto "${UNIVERSAL_OUTPUTFOLDER}/${PROJECT_NAME}.framework" "${HOME}/Desktop/${PROJECT_NAME}.framework"

Build it then your fat dynamic framework will be located on your desktop! Before submitting the App to AppStore, you must strip off the simulator slice (i386 x86_64) from the framework

lipo -remove i386 Name.framework/Name -output Path/name

lipo -remove x86_64 Name.framework/Name -output Path/name

After that, download the source code from

Before installing Cordova, you will require node.js which is downloaded from

If you do not have Cordova installed, then type

npm install -g cordova

Update Cordova

sudo npm update -g cordova

Go to the directory of source code, add cordova platform

cordova platform add android
cordova platform add ios

Install the IBM Bluemix plugin
cordova plugin add ibm-mfp-core

Go to /project-dir/www/js/index.js, paste your route & GUID
route: https://your-proj-name/
GUID: can be found in the first line of Cloud Foundry’s log in the panel

route: ""
GUID: ""

Open xcodeproj in /project-dir/platform/ios/
If it prompts to update latest swift version, cancel it.
Go to build settings tab and edit Objective-C Bridging Header
Find Runpath search Path, and add

Build Cordova
cordova build
Then run
cordova run android

Run iOS platform on Xcode

How to make a UIScrollView using Auto Layout

From the official document :

UIView: Position with constraints.
UIScrollView: Bind to UIView with constraints.
UIDetailView: Set size (intrinsic content size), max out compression-resistance, set top-, bottom-, leading- and trailing constraints to UIScrollView to 0 manually.

Now let’s set up the outlet as the image.

Next, select Scroll View and in the option menu : Editor -> Resolve Auto Layout Issues -> Add Missing Constraints

Select View under Scroll View in the Size Inspector, make its height as your desire.

And select View and in the option menu : Editor -> Resolve Auto Layout Issues -> Add Missing Constraints

Now we do some changes.

1. add Width 320 ( Editor ->Pin -> Width)

2. delete Center X alignment

3. Open Vertical Space – (-480) – Scroll View – View in Attributes Inspector

Set Constant : zero

Now the outlet will look like..

Then your ScrollView can be scrolled !

Change User Agent in iOS

Sometimes, different User Agents will show different content in the WebView.
in order to cater your html content, you will need to change UIWebView’s user agent.

Add the below code in AppDelegate.m

 + (void)initialize {

// Set user agent (the only problem is that we can’t modify the User-Agent later in the program)

NSDictionary *dictionnary = [[NSDictionary alloc] initWithObjectsAndKeys:@”Your User Agent”, @”UserAgent”, nil];

[[NSUserDefaults standardUserDefaults] registerDefaults:dictionnary];


Don’t forget to fill in “Your User Agent”.
For example, my user agent is

Mozilla/5.0 (iPad; CPU OS 7_1 like Mac OS X) AppleWebKit/537.51.2 (KHTML, like Gecko) Version/7.0 Mobile/11D167 Safari/9537.53

Find your own user agent from WhatsMyUserAgent

How to import library using cocoa pods

CocoaPods URL

Using CocoaPods is really easy to import Library to our iOS project.

I will show you how to import a library. I use MarqueeLabel as an example.

MarqueeLabel GitHub

First we need instal Ruby.
I use third-party-tool to install it.

Ruby Version Manager (RVM)

Type the following code in Terminal :

\curl -sSL | bash -s stable

After installing Ruby, we need to install CocoaPods now.

sudo gem install cocoapods

If you can't get anything now, maybe your Internet is blocked. I use these to change the install source.

gem sources --remove
gem sources -a

Type this to check

gem sources -l

It will then display :


Run install code again

sudo gem install cocoapods

After the installation completed, use cd command to direct to your project folder. Then, we create a Podfile using vim command

vim Podfile

Type the following

platform :ios, '7.1'
pod 'MarqueeLabel', '~> 1.4.1'

press Exit, and type   :wq    to exit editing with saving

Then install it now

pod install

Now you can open your Xcode (xworkspace)

open YourAppName.xcworkspace

Try to import it in your file

#import "MarqueeLabel.h"

Succeed ?
