在iOS開發過程中, 大堆的警告讓人很不爽，接下來介紹幾種消除警告的方法

《1》錯誤如下，是查詢 Library 的時候出現的異常找不到檔案在這個位置；如果你引用的 Frameworks 沒有在標準位置（standard locations），那麼，你需要在工程的配置檔案裡設定 “Framework Search Paths”， 用來為編譯器（compiler）和聯結器（linker）指定搜尋路徑。
ld: warning: directory not found for option ‘-L/’ XXX
ld: warning: “directory not found for option ‘-F/…”
解決方法
1>依次 Project -> targets -> Build Setting -> Library Search Paths
刪除裡面的路徑
2> 依次 Project -> targets -> Build Setting -> Framework Search Paths
刪除裡面的路徑

《2》 warning: Unsupported Configuration: This file is set to build for a version older than the deployment target. Functionality may be limited.
解決方法：
選中xib 的檔案 ， 跟著看圖， 最後在 Builds for 選中 Project 見下圖

《3》 問題 Automatic Preferred Max Layout Width before iOS 8.0
解決方法：
選中storyboard 的檔案 ， 參考看下圖， 最後在 Builds for 選中 Project改為iOS 8.0 and later 見下圖

《3》解決方法:
target >Build Phases > Compile Sources delete this file

《4》程式碼解決

//不同的警告替換雙引號中的程式碼 在.m檔案頂部新增
#pragma clang diagnostic ignored "-Wdeprecated-declarations"

在講icon font之前，首先先來看看普通自定義字體是如何在ios中使用的，兩個原理是一樣的。這裏以KaushanScript-Regular為例：

 數組遍歷是編碼中很常見的一種需求，我們來扒一拔iOS裏面都有什麽樣的方法來實現，有什麽特點。
