前言

最近忙完項目比較閑露懒，想寫一篇博客來分享一些自學(xué)iOS的心得體會闯冷，希望對迷茫的你有所幫助。博主非科班出身懈词，一些計算機(jī)術(shù)語上的不專業(yè)歡迎大家指正蛇耀。我是學(xué)微電子的，大四的時候找了一家深圳的專業(yè)對口的公司坎弯，任職SMT工程師（殺馬特工程師0.0）纺涤，就是做電路板生產(chǎn)的，在車間上班的那種抠忘，做了一年多漸漸感覺前途一片迷茫~

轉(zhuǎn)機(jī)

在2015年3月份的時候撩炊，我有一個同學(xué)來深圳找工作，住在我們那里崎脉。后來找了一個iOS培訓(xùn)班拧咳，我就叫他給一份老師的課件，每天下班都看幾個小時代碼囚灼，不懂的問題就等他晚上回來問他骆膝。于是乎，博主從此走上iOS之路灶体。博主窮屌絲一個阅签，筆記本不是蘋果的，于是我就各種百度蝎抽，在win7下裝了一個虛擬機(jī)黑蘋果政钟，終于能跑Xcode了，晚上下班就一邊看課件一邊敲代碼樟结，終于做出了一個簡單的微信界面养交，心里還是挺高興的。后面用一個抓包工具paros抓取上架App的公共Api練習(xí)獲取網(wǎng)絡(luò)數(shù)據(jù)瓢宦，也能做出簡單的App层坠。

辭職告別SMT，入職加入iOS

經(jīng)過幾個月的苦學(xué)刁笙，覺得自己可以做App了，就果斷辭職谦趣，開始找工作疲吸。剛開始的時候投簡歷有回復(fù)的不是培訓(xùn)機(jī)構(gòu)就是電話里就拒絕了，感覺挺絕望的前鹅。但是功夫不負(fù)有心人摘悴，面試了一周終于有家公司想培養(yǎng)新人，于是就入職了舰绘。

然而蹂喻，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(xué)點技術(shù)的葱椭，無奈只能硬著頭皮上了。那時公司剛好有個智能手環(huán)的項目比較急口四，真是每天加班加點孵运，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蔓彩。

總結(jié)及建議

1.并不是每個人都能像我這么幸運遇到一個接觸iOS的機(jī)會治笨，在此我要感謝我的那位同學(xué)。但是如果你感興趣或者想入門iOS赤嚼，只要你有C語言基礎(chǔ)就行旷赖，博主大學(xué)四年都是搞硬件開發(fā)的，就是用C語言編程控制單片機(jī)更卒，有C語言基礎(chǔ)上手iOS非车确酰快，因為Object C是C語言的超集也就是說他基于C語言蹂空，在此附上Object C程序設(shè)計PDF下載地址：

http://download.csdn.net/detail/longteng7878/8875929

2.其實開始對于OC里面的一些術(shù)語還是不太明白俯萌，不要緊，博主由于忙著做項目腌闯，第一個上線的項目是逼出來的绳瘟，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姿骏，這是我個人的經(jīng)驗糖声。比如OC里面的對象，實例分瘦，類蘸泻，一開始老是弄混淆，現(xiàn)在基本上都理解了嘲玫。

3.當(dāng)你基本上把OC的書看得差不多的時候悦施，就可以開始你iOS的第一步了，如果你有條件就買個mac mini吧去团，也不貴抡诞，沒條件就和博主一樣，在win7裝個虛擬機(jī)黑蘋果土陪，Xcode這個軟件不難昼汗，有點英文基礎(chǔ)的人用起來都挺簡單，一般的開發(fā)軟件新建工程的步驟都差不多鬼雀，這里我就不啰嗦了顷窒。你可以網(wǎng)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源哩，熟悉了UI一些基本控件的使用之后鞋吉，就可以用抓包工具paros鸦做，隨意在安卓市場上找簡單的App，抓取該App的公共Api谓着，用系統(tǒng)網(wǎng)絡(luò)請求或者AFNetworking方法獲取網(wǎng)絡(luò)數(shù)據(jù)泼诱。之后試著搭建這個App的界面并且獲取數(shù)據(jù)，最后大致做出這個App漆魔。

此處附上簡單的微信界面demo:（代碼是博主從工程復(fù)制拷貝成的txt文件坷檩，有些地方如頭文件顯示不出來，請自行加上改抡，tableViewCell用Xib做的）

4.當(dāng)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洲愤，不是科班出身也不用驚慌吕粹，博主就是學(xué)硬件的践叠，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(tài)度夠誠懇，工資方面壓低一些格带，一般都沒什么問題的。先入門刹枉，進(jìn)入一個平臺實習(xí)叽唱，以后工資會漲得很快的。

總結(jié)一下：只要你感興趣微宝，努力用心去學(xué)棺亭，沒有什么做不到的。（以上一些關(guān)于在iOS實際應(yīng)用中遇到的問題博主會逐漸更新蟋软，盡請期待Ｏ庹）

越努力，越幸運岳守！

以現(xiàn)在大多數(shù)人的努力程度之低钉稍，根本輪不到可以拼天賦。
