Android vs iOSCOMPARISON

Aspects• Project structure

• Output final type

• Components build up

• Some other kind of facing

• Using style

Project structure

Output final type• .IPA

• .APK

Components build up• Naming

– NSString >< String

– NSObject ><Object

– NSInteger ><Integer

– ….

– UIView >< View

– UIButton >< Button

– UILabel >< Label

– UITextField >< EditText

– ….

• Storage– NSUserDefault ><SharedPrefrence

• Layout– .XIB>< .XML

• Controller– UIViewController >< Activity

• Logging– NSLog >< Log

• List Data– UITableView>< ListView

• Notification– iToast >< Toast

– UIAlert ><Alert

Some other kind of facing• Declare

• Import libs

• Switching screen

• UnitTest

• ATT

Declare

Object object = new Object();Student student = new Student("Nguyen Tuan Anh", "24", "Male");

Class Student{private String name;private int age;private String gender;

public Student(String name, int age, String gender){this.name = name;this.age = age;this.gender = gender;

}}

Import Libs• Same as:

– Add from static library:• .a >< .jar

– Add module: same way.

– Add from resource : • Cocoapod >< Maven

• Podfile >< pom.xml

Switching screen• IOS :

– Don’t have default screen

– Self.window setRootViewController

– Using navigation controller to deligate• pushViewController

• popViewController

• Android:– Using IntentFilter set default screen

– Throw an Intent to transfer data + switch screen

– Replace screen if using fragment

(using Support-V4 with FragmentManager)

Using style• Debugging

• Looping: for | while | do while | ..

• Constructor( init )

• MultiScreen

• MultiVersion

• Transfer data between multible screen

Debugging iOS

Debugging android

MultiScreen• IOS:

– IPad

– Iphone• pixel density:

– Rentina

– Not rentina

• Size screen:– 3.5 : Ip4

– 4 : Ip5

– 4.7 : Ip6 (near future)

– Something others

• Android: there are many way to understand it

– Pixel density:• Mdpi

• Hdpi

• Xhdpi

• Xxhdpi

• xxxhdpi

– Size screen:• Small

• Normal

• Large

• Xlarge

• XXLarge

MultiScreen

Transfer data between screens• iOS:

– setup next screen in current screen & prepare data for it before start.

– Other way:• No suggest

• File– SQLite

– NSUserDefault

– Core data (file has structure)

– …

• Android:– Same as model driven - new

way was applied this time.

– Other way:• Put data into Intent as bundle

• File– SQLite

– SharedPreference

– Simple file
