[Android] Set proper JDK on Mac

Got a error on Android Studio, it said that it need JDK7.

Found that: if you install java8 update25, which is the newest Java update on Mac, the default JDK is 6 not 7.

official info: http://support.apple.com/kb/DL1572

But the Android studio default recommend JDK version is 7.

So you need to download the JDK7 from here:
http://www.oracle.com/technetwork/java/javase/downloads/jdk7-downloads-1880260.html

1.Open the dmg, and install.

2.In your android studio, go to File> Project Structure> SDK Location

3.In "JDK location" click on browse and go to /Library/Java/JavaVirtualMachines/jdk1.7.0_60.jdk/Contents/Home
(Note :- Its Not /System/Library it's /Library)

4. apply, then ok!

[ios] 兩個viewcontroller之間傳值, Passing value between two viewcontroller

A viewcontroller --> B viewcontroller

有兩個方法
1. delegate - 適合非storyboard的狀況，或是用storyboard但啟動B viewcontroller的時候非用storyboard segue的方式（只拿storyboard來刻畫面，但不在storyboard中進行畫面切換設定）

2. (void)prepareForSegue:(UIStoryboardSegue *)segue sender:(id)sender
適合storyboard狀況


參考：

Delegate的使用方法，ola大大這篇寫的很好，要是當年第一次接觸delegate就有這篇，也不會一把鼻涕一把眼淚的學T_T
