2.Xcode編譯出現(xiàn)如下警告提示：

[WARN]warning: no rule to process file xxx.h’ of type sourcecode.c.h for architecture armv7

解決辦法:這是因?yàn)闄z查到有.h文件在編譯列表中了。所以只要在列表中去掉就可以了。

點(diǎn)擊你的xcode項(xiàng)目文件，然后點(diǎn)擊[Build Phases]，確保在[Compile Sources]中沒有.h文件。

解決辦法：從輸出的日志可以看出問題是出在鏈接，由Cocoapods管理的第三方庫(kù)安裝后鏈接配置項(xiàng)沒有設(shè)置正確，需要手動(dòng)設(shè)置沒有被自動(dòng)鏈接的庫(kù)，例如這里我需要鏈接：-l"Pods-CocoaAsyncSocket"。

10.導(dǎo)航欄如何顯示兩行文本？

解決辦法：After setting up your titleView or titleLabel, call sizeToFit on it, also make sure titleLabel.textAlignment = UITextAlignmentCenter. It’ll be centered in the width of the navbar rather than in the space between the button edge and far edge of navbar.

12.Calling a C function from within a function in a .mm file

解決辦法：The .mm file is looking to call a mangled version of the function name. You need either?BEGIN_DECLS and?END_DECLS around the C function declarations seen by the C++-compiled file, or you need to do the equivalent yourself. The idea is to mark those function declarations as extern “C” when seen by an (Obj-)C++ compiler, but not when seen by any other sort of compiler.
