Swift - AppToApp communication
communicate with using URL
---------
create url schemes
go to prokject-> info -> urlTypes
fill identifier - Actually there is no usage at all. you can use anything. only the sceme and role considered.
URL schemes - unique app scheme which other apps use to open the app, cannot use existing ios system schemes in here (https://developer.apple.com/library/content/featuredarticles/iPhoneURLScheme_Reference/Introduction/Introduction.html#//apple_ref/doc/uid/TP40007899)
Role -
Editor - schemes if we are defines
Viewer - existing schemes in iOS system (like photo viewer, email , sms apps)
how it works
if we want to open app2 from app1
in app2
identifier - dont know the correct usage. in apple Doc also not gives a full Description
schecme - used iPay
role - Editor (this is our own define scheme. so need to use as Editor. if systemdefine scheme should as view)
in App1
app1 we should also have to define url scheme for matching for appys2. scheme should be same and role should None.
identifier - can use anything
schecme - used iPay
role - None
let kCustomURLScheme = "ipay://" // only the sceme used. not identifier
let customURL = URL(string: customURLScheme)!
if UIApplication.shared.canOpenURL(customURL) {
if #available(iOS 10.0, *) {
UIApplication.shared.open(customURL, completionHandler: { (success) in
print("Open url : \(success)")
})
} else {
UIApplication.shared.openURL(customURL)
}
return true
}
** if we use same scheme for two application
system starts first installed application. if we uninstall first app then it will open second app.
Swift push notification
create project
add required POD
create apns key in apple developer portal
upload that token in to firebase project
------------
push notfication in appDelegate method execution steps
didFinishLaunchingWithOptions
didReceiveRegistrationToken -- this return the push token
didRegisterForRemoteNotificationsWithDeviceToken -- this will run when app kill and run again
send notification from firebase
app is in foreground - userNotificationCenter - willPresent
app in bg -
notification shows in notification bar
click on notification' - userNotificationCenter - didReceive
app kill and send notification (same as above)
notification shows in notification bar
click on notification' - userNotificationCenter - didReceive
-------------
{
"to": "PUSH_TOKEN_HERE",
"notification": {
"body": "You have authorized LKR 20.00 to test from your A/C *******0269 on 23-04-2018 at 11:10. TXN ID : 20857",
"title": "Payment Successful !!",
"icon": ""
},
"data": {
"notificationType": "WEB_PAYMENT",
"data": {
"instrumentReference": "W000000000000631"
}
}
}
notification - this part automatically handled by app when only app in background (both android and ios). it shows notification. we need to pass body and title
data - this part only trigger when app is in forground (in both ios & android). we can catch these values inside data object.
CocoaPods
CocoaPods manages library dependencies for your Xcode projects.
The dependencies for your projects are specified in a single text file called a Podfile. CocoaPods will resolve dependencies between libraries, fetch the resulting source code, then link it together in an Xcode workspace to build your project.
POD
command line tool to work with pod files
Installation
sudo gem install cocoapods
pod required ruby installation. checko ruby version
ruby -v
to maintain pod local repository use
pod setup
this will create master repo in user-> name-> .cocoapods -> repos...
i think this is lile maven repo. we can maintain repo from local rather than downloading same repo.
this is the main repo path
https://github.com/CocoaPods/CocoaPods
add pod in to project
pod init
to init pod it needs a xcode project. without project no pod init ;)
this will create a pod file.
open pod file using text editor
use xcode interminal use this command
open -a Xcode Podfile
adding required library projects as this
pod 'JLocationKit', '~> 1.0.3'
downloading lib projects
pod install
update missing pods
pod install --repo-update
to run pod project open xcode using App.xcworkspace
do not open using project file
remove pod from a project
$ sudo gem install cocoapods-deintegrate cocoapods-clean
$ pod deintegrate
$ pod clean
$ rm Podfile
uiviewcontroller life cycle
viewDidLoad
viewWillAppear
viewDidAppear
applicationDidBecomeActive - AppDelegate
applicationWillResignActive - AppDelegate
home click
----------
applicationDidEnterBackground - AppDelegate
applicationWillEnterForeground - AppDelegate
again open app from icon click
--------------
applicationDidBecomeActive - AppDelegate
applicationWillResignActive - AppDelegate
app killed by using running apps
---------------
applicationWillTerminate - AppDelegate
viewDidLoad - oncreate
viewWillAppear - onresume
viewDidAppear - onresume
viewWillDisappear - onpause ( these will called when open another controller, not at home click )
viewDidDisappear - ondestroy ( these will called when open another controller , not at home click)
Swift localization
select project-> info -> localization
click + sign and select required languages
in ios string files can add in two places
for storyboard wise localization
these strings cannot apply programatically
in inspector tab select required locations
this will create new string files in project->project name folder-> lancode.IProj folder -> Main.String
if launcher storyboard localization added it will create LaunchScreen.strings file in same folder
*** These language applied when user changed the device language in setting.
when app specific language change can do by changing the budle as below. but user needs to restart the app to use these strings.
programatically access strings
select project-> new file -> String -> name as Localizable.strings (name should be this)
this will create a file in project-> Localizable.strings file
select that file and click localize button in inspector tab
select required languages
add strings in this format
"key" = "value";
these string files access in program by attach bundle path to these files. to change path
let path: String? = Bundle.main.path(forResource: lang, ofType: "lproj")
if path == nil {
bundle = Bundle.main
}
else {
bundle = Bundle(path: path!)
}
Swift- Working with rest service
protocol - rules
subdomain - point a more specifc server or etc
domain - unique reference to specific site
port -
path - refer specifi sub directory or file
query param - more detail of request
request type - GET, POST etc
headers - key value pair which tells server how to handle the request
response also has header which describe how the client use the information
body - data send or received
playgroud setup for network request
playground default support for synchronous request. means lines runs top to bottom. so to call network requet has some changes in playground. add these lines in top
import PlaygroundSupport
PlaygroundPage.current.needsIndefiniteExecution = true
///////////////////////
like in java we can seperately invoke service call and get the response as callback function. everything step by step in here. last class is using all concepts
import Foundation
import PlaygroundSupport
PlaygroundPage.current.needsIndefiniteExecution = true // make playgroud to run asnchronous request
//let url = URL(string: "https://api.nasa.gov/planetary/apod?api_key=NNKOjkoul8n1CH18TWA9gwngW1s1SmjESPjNoUFo")!
//let task = URLSession.shared.dataTask(with: url) { (data, response, error) in
//// if let data = data {

// //get as json object
// if let data = data,
// let string = String(data: data, encoding: .utf8) {
