iOS设置Pch文件

1.) 打开你的Xcode工程. 在Supporting Files目录下,选择 File > New > File > iOS > Other > PCH File 然后点击下一步;

2.) 给你的PCH文件起名字TestDemo-Prefix.pch. 例如你的项目工程名为TestDemo然而你的PCH 文件的名字应该为 TestDemo-Prefix.pch,然后创建;

4.) 找到 Project > Build Settings > 搜索 “Prefix Header“;

5.) “Apple LLVM 7.0 -Language″ 栏目中你将会看到 Prefix Header 关键字;

6.) 输入: $(SRCROOT)/YourProjectName/YourProject-Prefix.pch (如 TestDemo/TestDemo-Prefix.pch );

7.),将Precompile Prefix Header为YES,预编译后的pch文件会被缓存起来,可以提高编译速度。

//十六进制颜色设置

public let ScreenWidth: CGFloat = UIScreen.main.bounds.size.width
public let ScreenHeight: CGFloat = UIScreen.main.bounds.size.height
public let ScreenBounds: CGRect = UIScreen.main.bounds
//swift版
public func DLog(message: T, file: String = #file, method: String = #function, line: Int = #line) {
    #if DEBUG
        print("<\((file as NSString).lastPathComponent) : \(line)>, \(method)  \(message)")
    #endif
}
