終於 – iTunes Connect 改善了

以前上架 iOS app 時

都要上傳各尺寸的螢幕截圖

3.5″ 4″ 4.7″ 5.5.” 四種大小

如果每個 5 張,就得要 5×4=20 張

今天上架時

發現只要上傳最大的解析度即可

5.5″ (1242×2208)

其他較小的尺寸預設就會自動套用

(當然,如果要自己上傳各尺寸也是可以)

真是 iOS Developer 的一大福音…

OneSignal Push Notification with Android Studio practice log

It took me one night to make it work, so I’d like to write it down for next time.

Main Flow as follow diagram:

MainFlowchart

Green fields means “what values you can get”

White fields means “what values you should set”

And following are screeshots for each steps

1.Google Developer Console (GCM)

Get these two values.

GoogleDeveloperConsole

2.Set the Server API Key in OneSignal

Set  OneSignal「Server API Key」to 「Server API Key」in Step 1

OneSignal_ServerAPIKEY

3.Set the Project number in Android Studio MainFest.xml (onesignal_google_project_number)

Set the onesignal_google_project_number to 「Sender ID」in Step 1

AndroidStudio_bundlegradle_app

4.Onesignal (App Settings -> Keys & IDs)

Get these values.

OneSignal_appid

5.Set the OneSignal App ID in Android Studio MainFest.xml (onesignal_app_id)

Set the onesignal_app_id to 「OneSignal App ID」in Step 4

AndroidStudio_bundlegradle_app

6.Include libraries in Android Studio

This is according to the OneSignal document

AndroidStudio_bundlegradle_app_dependencies

 

Basically this is all you have to do to send push notification to Android devices via OneSignal and Android Studio.

By the way, I used to use the CUrl script provided by OneSignal to test sending notification, here’s a sample for your reference.

7.CUrl script

There are two fields to be set.

「Authorization Basic」 : set to 「REST API Key」in Step 4

「app_id」: set to 「OneSignal App ID」in Step 4

Curl_CommandLine

 

That’s all, happy pushing !!

Facebook Signin Practice Log

Facebook signin ios

Follow the official document procedure
https://developers.facebook.com/docs/facebook-login/ios

1.Download SDK and setup the environment
https://developers.facebook.com/docs/ios/getting-started

Create new Facebook app
1.FB app 2 of 2

1.FB app 1 of 2

2.Configure the XCode project parameters
Info.plist

2.InfoPlist

For AppTransportSecurity parameters, you can follow the Facebook direction, or you can just “allow all” as follow

<key>NSAppTransportSecurity</key>
<dict>
<key>NSAllowsArbitraryLoads</key>
<true/>
</dict>

3.Modify the source code

3.1 AppDelegate
#import <FBSDKCoreKit/FBSDKCoreKit.h>

– (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions {
[[FBSDKApplicationDelegate sharedInstance] application:application didFinishLaunchingWithOptions:launchOptions];
….
}

3.2 ViewController you want to do Facebook Signin
#import <FBSDKCoreKit/FBSDKCoreKit.h>
#import <FBSDKLoginKit/FBSDKLoginKit.h>

-(void)loginAsFacebook {
FBSDKLoginManager *login = [[FBSDKLoginManager alloc] init];
[login logInWithReadPermissions:  @[@”public_profile”, @”email”, @”user_friends”] fromViewController:self handler:^(FBSDKLoginManagerLoginResult *result, NSError *error) {
if (error) {
NSLog(@”Process error”);
} else if (result.isCancelled) {
NSLog(@”Cancelled”);
} else {
NSLog(@”Logged in”);

NSLog(@”[%@][%@][%@][%@]”, [[FBSDKAccessToken currentAccessToken]appID],
[[FBSDKAccessToken currentAccessToken]userID],
[[FBSDKAccessToken currentAccessToken]refreshDate],
[[FBSDKAccessToken currentAccessToken]tokenString]
);

//Get some profile data
FBSDKGraphRequest *requestMe = [[FBSDKGraphRequest alloc]initWithGraphPath:@”me” parameters:@{@”fields”: @”email, first_name, last_name”}];
FBSDKGraphRequestConnection *connection = [[FBSDKGraphRequestConnection alloc] init];
[connection addRequest:requestMe completionHandler:^(FBSDKGraphRequestConnection *connection, id result, NSError *error) {
if(result) {
NSString *sUserID, *sEmail, *sFirstName, *sLastName;
if ([result objectForKey:@”email”]) {
sEmail = [result objectForKey:@”email”];
}
if ([result objectForKey:@”first_name”]) {
sFirstName = [result objectForKey:@”first_name”];
}
if ([result objectForKey:@”last_name”]) {
sLastName = [result objectForKey:@”last_name”];
}
if ([result objectForKey:@”id”]) {
sUserID = [result objectForKey:@”id”];
}

NSLog(@”Customer details:[%@][%@][%@][%@]”, sUserID, sFirstName, sLastName, sEmail);

//Facebook account was authenticated OK, do whatever you need
}];
[connection start];
}
}];
}

Google SignIn iOS practice log

Google Sign-in for iOS

1.Download GoogleSignIn SDK
https://developers.google.com/identity/sign-in/ios/sdk/
There are two ways to get the SDK, CocoaPod or direct download,
Personally I preferred the download way.
0.Download SDK
Follow the official document procedure
https://developers.google.com/identity/sign-in/ios/start

2.Get configuration file
https://developers.google.com/mobile/add?platform=ios&cntapi=signin&cntapp=Default%20Demo%20App&cntpkg=com.google.samples.quickstart.SignInExample&cnturl=https:%2F%2Fdevelopers.google.com%2Fidentity%2Fsign-in%2Fios%2Fstart%3Fconfigured%3Dtrue&cntlbl=Continue%20with%20Try%20Sign-In

2.EnableSignin

 

3.Copy to project directory first then “pull” into xcode project
Basically just pull the configuration file into the xcode project  and it is OK.
But you will gonna thank me for this lousy procedure when there are multiple configuration files in one xcode project.
3.Download plist
4.Configure xcode project-level parameters
https://developers.google.com/identity/sign-in/ios/sign-in?configured=true

Put REVERSED_CLIENT_ID into Project -> Target -> Info -> URL Types
Put bundle id into Project -> Target -> Info -> URL Types

4.URLTypes

 

5.Modify source code
There will be only one file to be modified – AppDelegate

The most important statement is to set [GIDSignIn sharedInstance].clientID = CLIENT_ID(in configuration)

iOS 的 app 真麻煩

iOS 的版本只要一升級

就得回頭 revise 所有的 app

要不然就會莫名其妙的閃退

日前心血來潮看了一下這個 app

才發現早就閃退到不行

只好趕快改一改再上架更新

XCode SVN is not under version control

That is the keyword I Googled for solution and no luck.

I’m too old to learn new source control mechanism like Git so I stuck on SVN with XCode.

It works perfect usually but sometimes it show “xxx is not under version control”.

For me, the reason is some special character in file name , in my case , the @ character.

I googled and tried to fixed this issue but no luck.

And today, finally, I solved this issue with one single step, simple and straight.

Open “Terminal” application, go to the project folder and keyin this

svn commit -m “Happy SVN”

And you’ll see all the files (including file name with @ character) are committed successfully.

I don’t know why the commit won’t succeed in XCode, but I’m happy that it works in command line mode.

 

Update on 2016/03/02:

Sometimes you have to make those @xx.png files the Add status (with A in the right) in Xcode first before you do the command-line svn commit.

Custom URL schemes practice

Let’s define something in this scenario :

1.Receiver app – to be invoked via custom URL

2.Sender app – who wants to invoke the app

3.Custom URL scheme – define as “happygo”

 

 

For Receiver app, here’s what to do:

1.Define the url scheme in Project/Targets/Info/URL Types as follow

螢幕快照 2016-02-04 下午12.20.51

2.AppDelegate.m – Two methods to be implemented.

- (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions {
 return YES;    //must return YES
 }
- (BOOL)application:(UIApplication *)application openURL:(NSURL *)url sourceApplication:(NSString *)sourceApplication annotation:(id)annotation {
 //Check if the scheme was valid
 if ([[url scheme] isEqualToString:@"happygo"]) {
 NSString *query = [url query];
 NSArray *queryComponents = [query componentsSeparatedByString:@"&"];

 for (int i=0; i<[queryComponents count]; i++) {
 NSArray *oneParam = [[queryComponents objectAtIndex:i] componentsSeparatedByString:@"="];
 NSString *sValue = @"";
 NSString *sKey = [oneParam objectAtIndex:0];
 if (oneParam.count==2) {
 sValue = [oneParam objectAtIndex:1];
 }
 }
 //Here is what you want to do, write here.
 return TRUE;   //return TRUE because of valid scheme
 }
 return FALSE;   //invalid scheme, skip process
 }

 

 

For Sender app, here’s what to do :

1.Add the following to info.plist

<key>LSApplicationQueriesSchemes</key>
 <array>
 <string>happygo</string>
 </array>

2.Invoke the receiver app via URL form, sample source code as follow

NSString *sURL = [NSString stringWithFormat:@"happygo://www.domain.com?name=Good&phone=123123"];
 NSURL *myURL = [NSURL URLWithString:sURL];

 if ([[UIApplication sharedApplication] canOpenURL:myURL]) {
 [[UIApplication sharedApplication] openURL:myURL];
 } else {
 NSLog(@"--bad url--");
 }

Actually, you can even invoke the app via Safari Browser.

Just input the URL in Safari, press GO, and the receiver app will be invoked.
