Java遇到AES加解密問題

遇到Java Security: Illegal key size or default parameters，解決方式如下：

Java Cryptography Extension (JCE) Unlimited Strength Jurisdiction Policy Files 6
Java Cryptography Extension (JCE) Unlimited Strength Jurisdiction Policy Files 7 Download
Java Cryptography Extension (JCE) Unlimited Strength Jurisdiction Policy Files 8 Download
在去把檔案丟到 ${java.home}/jre/lib/security/ 裡就可以了

Xcode 7.2 安裝CocoaPods

安裝CocoaPods

打開Terminal(終端機)，打以下的的指令：

$ sudo gem install cocoapods

1. 用Xcode新增一個專案
2. 用Terminal(終端機)，cd .../專案/，打以下的指令

$ pod init

3. 在打上

$ pod install

4. 以上指令跑完後，會新增 專案.xcworkspace，以後就直接開.xcworkspace的檔案

Xcode 7 上架時遇到 憑證無效...

Xcode 7 上架時遇到 unexpected cfbundleexecutable key ... googleplus.bundle ... 錯誤

解決方式：
在找出你import的googleplus.bundle
1. googleplus.bundle/Info.plist
2. googleplus.bundle/GPPCommonSharedResources.bundle/Info.plist
3. googleplus.bundle/GPPShareboxSharedResources.bundle/Info.plist
請將這三個檔案的Executable file -> string 的值 清除

Ubuntu OpenSSL 更新或安裝

一、確認OpenSSL版本

# openssl version

二、下載你要更新的版本
OpenSSL 下載連結

# wget https://openssl.org/source/openssl-1.0.2d.tar.gz 
# tar -zxvf openssl-1.0.2d.tar.gz -C /usr/local/src

三、安裝

# cd /usr/local/src/openssl-1.0.2d
# ./config
# make
# make install

安裝完後，請移動資料夾

# mv /usr/bin/openssl /root/
# ln -s /usr/local/ssl/bin/openssl /usr/bin/openssl

後來在確認是否有更新版本

# openssl version

Xcode 7 使用google+ SDK遇到錯誤

GoogleOpenSource.framework/GoogleOpenSource(GTLDateTime.o)' does not contain bitcode. You must rebuild it with bitcode enabled (Xcode setting ENABLE_BITCODE), obtain an updated library from the vendor, or disable bitcode for this target. for architecture arm64

我們只要進入 Build Settings -> Build Options 將 Enable Bitcode 改成NO

Swift 2 Xcode7.1 Facebook SDK + 自訂Facebook Button

一、下載Facebook SDK

• FacebookSDKs-iOS-20151111.zip

二、Xcode開新專案
編輯專案下的info.plist
新增以下設定
Facebook developer key 記得先去申請 Facebook Developer

<key>CFBundleURLTypes</key>
<array>
  <dict>
    <key>CFBundleURLSchemes</key>
    <array>
      <string>fb{your-app-id}</string>
    </array>
  </dict>
</array>
<key>FacebookAppID</key>
<string>{your-app-id}</string>
<key>FacebookDisplayName</key>
<string>{your-app-name}</string> 

<key>NSAppTransportSecurity</key>
<dict>
  <key>NSExceptionDomains</key>
  <dict>
    <key>facebook.com</key>
    <dict>
      <key>NSIncludesSubdomains</key> <true/>        
      <key>NSThirdPartyExceptionRequiresForwardSecrecy</key> <false/>
    </dict>
    <key>fbcdn.net</key>
    <dict>
      <key>NSIncludesSubdomains</key> <true/>
      <key>NSThirdPartyExceptionRequiresForwardSecrecy</key>  <false/>
    </dict>
    <key>akamaihd.net</key>
    <dict>
      <key>NSIncludesSubdomains</key> <true/>
      <key>NSThirdPartyExceptionRequiresForwardSecrecy</key> <false/>
    </dict>
  </dict>
</dict>

三、將.framework檔放入
先new Group，名稱為Frameworks
在將FBSDKCoreKit.framework，FBSDKLoginKit.framework，FBSDKShareKit.framework放入Frameworks裡

四、寫程式
1.AppDelegate.swift

import UIKit
import CoreData
import FBSDKCoreKit

@UIApplicationMain
class AppDelegate: UIResponder, UIApplicationDelegate {

    var window: UIWindow?


    func application(application: UIApplication,
        openURL url: NSURL,
        sourceApplication: String?,
        annotation: AnyObject) -> Bool {
            return FBSDKApplicationDelegate.sharedInstance().application(
                application,
                openURL: url,
                sourceApplication: sourceApplication,
                annotation: annotation)
    }
.....
}

2.ViewController.swift

import UIKit
import FBSDKCoreKit
import FBSDKShareKit
import FBSDKLoginKit

class ViewController: UIViewController {
    let fbLoginManager : FBSDKLoginManager = FBSDKLoginManager()
    override func viewDidLoad() {
        super.viewDidLoad()
    }
    
    override func didReceiveMemoryWarning() {
        super.didReceiveMemoryWarning()
        // Dispose of any resources that can be recreated.
    }
    @IBAction func loginAction(sender: AnyObject) {
        
        fbLoginManager.logInWithReadPermissions(["email"],fromViewController: self.parentViewController, handler: { (result, error) -> Void in
            if (error == nil){
                let fbloginresult : FBSDKLoginManagerLoginResult = result
                if(fbloginresult.grantedPermissions.contains("email"))
                {
                    self.getFBUserData()
                    self.fbLoginManager.logOut()
                }
            }
        })
        
    }
    func getFBUserData(){
        if((FBSDKAccessToken.currentAccessToken()) != nil){
            FBSDKGraphRequest(graphPath: "me", parameters: ["fields": "id, name, first_name, last_name, picture.type(large), email"]).startWithCompletionHandler({ (connection, result, error) -> Void in
                if (error == nil){
                    print(result)
                }
            })
        }
    }
    @IBAction func logoutAction(sender: AnyObject) {
        
        fbLoginManager.logOut()
    }
    
}

打完收功...
