談談入門iOS的經驗吧
前言
最近忙完項目比較閒，想寫一篇博客來分享一些自學iOS的心得體會，希望對迷茫的你有所幫助。博主非科班出身，一些計算機術語上的不專業歡迎大家指正。我是學微電子的，大四的時候找了一家深圳的專業對口的公司，任職SMT工程師（殺馬特工程師0.0），就是做電路板生產的，在車間上班的那種，做了一年多漸漸感覺前途一片迷茫~
轉機
在2015年3月份的時候，我有一個同學來深圳找工作，住在我們那裡。後來找了一個iOS培訓班，我就叫他給一份老師的課件，每天下班都看幾個小時代碼，不懂的問題就等他晚上回來問他。於是乎，博主從此走上iOS之路。博主窮屌絲一個，筆記本不是蘋果的，於是我就各種百度，在win7下裝了一個虛擬機黑蘋果，終於能跑Xcode了，晚上下班就一邊看課件一邊敲代碼，終於做出了一個簡單的微信界面，心裡還是挺高興的。後面用一個抓包工具paros抓取上架App的公共Api練習獲取網絡數據，也能做出簡單的App。
辭職告別SMT，入職加入iOS
經過幾個月的苦學，覺得自己可以做App了，就果斷辭職，開始找工作。剛開始的時候投簡歷有回復的不是培訓機構就是電話裡就拒絕了，感覺挺絕望的。但是功夫不負有心人，面試了一周終於有家公司想培養新人，於是就入職了。
然而，我的老大在我入職的第四天就遞給我交接單離職高飛了
本來還想抱個大腿多學點技術的，無奈只能硬著頭皮上了。那時公司剛好有個智能手環的項目比較急，真是每天加班加點，狼吞虎咽的消化新知識，特別是App第一次上線的那晚搞到半夜兩點才下班。
總結及建議
1.並不是每個人都能像我這麼幸運遇到一個接觸iOS的機會，在此我要感謝我的那位同學。但是如果你感興趣或者想入門iOS，只要你有C語言基礎就行，博主大學四年都是搞硬件開發的，就是用C語言編程控制單片機，有C語言基礎上手iOS非常快，因為Object C是C語言的超集也就是說他基於C語言，在此附上Object C程序設計PDF下載地址：
http://download.csdn.net/detail/longteng7878/8875929
2.其實開始對於OC裡面的一些術語還是不太明白，不要緊，博主由於忙著做項目，第一個上線的項目是逼出來的，有些代碼能理解就盡量理解，不能理解的做多了你自然就懂了，這是我個人的經驗。比如OC裡面的對象，實例，類，一開始老是弄混淆，現在基本上都理解了。
3.當你基本上把OC的書看得差不多的時候，就可以開始你iOS的第一步了，如果你有條件就買個mac mini吧，也不貴，沒條件就和博主一樣，在win7裝個虛擬機黑蘋果，Xcode這個軟件不難，有點英文基礎的人用起來都挺簡單，一般的開發軟件新建工程的步驟都差不多，這裡我就不啰嗦了。你可以網上找一些UI界面的demo,比如微信界面，試著自己敲代碼去搭建，熟悉了UI一些基本控件的使用之後，就可以用抓包工具paros，隨意在安卓市場上找簡單的App，抓取該App的公共Api，用系統網絡請求或者AFNetworking方法獲取網絡數據。之後試著搭建這個App的界面並且獲取數據，最後大致做出這個App。
此處附上簡單的微信界面demo:（代碼是博主從工程復制拷貝成的txt文件，有些地方如頭文件顯示不出來，請自行加上，tableViewCell用Xib做的）

4.當你能基本完成以上幾點的時候，就可以試著找工作了，如果你是科班出身找工作會比較好找，不是科班出身也不用驚慌，博主就是學硬件的，一樣可以找得到。面試的時候能答出一些基本的問題，只要你態度夠誠懇，工資方面壓低一些，一般都沒什麼問題的。先入門，進入一個平台實習，以後工資會漲得很快的。
總結一下：只要你感興趣，努力用心去學，沒有什麼做不到的。（以上一些關於在iOS實際應用中遇到的問題博主會逐漸更新，盡請期待！）
越努力，越幸運!
