Swift 中没有宏定义,苹果建议使用let
或者 get 属性来替代宏定义值。虽然没有#define,但我们仍然可以使用 #if
并配合编译的配置来完成条件编译。下面会列出Swift项目开发中的一些常用宏定义,并提供源码。
1.常用字体宏定义
import Foundation import UIKit /// 系统普通字体 var gof_SystemFontWithSize: (CGFloat) -> UIFont = {size in return UIFont.systemFontOfSize(size); } /// 系统加粗字体 var gof_BoldFontWithSize: (CGFloat) -> UIFont = {size in return UIFont.boldSystemFontOfSize(size); } /// 仅用于标题栏上,大标题字号 let kNavFont = gof_SystemFontWithSize(18); /// 标题字号 let kTitleFont = gof_SystemFontWithSize(18); /// 正文字号 let kBodyFont = gof_SystemFontWithSize(16); /// 辅助字号 let kAssistFont = gof_SystemFontWithSize(14);
2.常用颜色宏定义
import Foundation import UIKit /// 根据RGBA生成颜色(格式为:22,22,22,0.5) var gof_RGBAColor: (CGFloat, CGFloat, CGFloat, CGFloat) -> UIColor = {red, green, blue, alpha in return UIColor(red: red / 255, green: green / 255, blue: blue / 255, alpha: alpha); } /// 根据RGB生成颜色(格式为:22,22,22) var gof_RGBColor: (CGFloat, CGFloat, CGFloat) -> UIColor = {red, green, blue in return UIColor(red: red / 255, green: green / 255, blue: blue / 255, alpha: 1); } /// 根据色值生成颜色(无透明度)(格式为0xffffff) var gof_ColorWithHex: (NSInteger) -> UIColor = {hex in return UIColor(red: ((CGFloat)((hex & 0xFF0000) >> 16)) / 255.0, green: ((CGFloat)((hex & 0xFF00) >> 8)) / 255.0, blue: ((CGFloat)(hex & 0xFF)) / 255.0, alpha: 1); } /// 黑色 let kBColor = gof_ColorWithHex(0x000000); /// 白色 let kWColor = gof_ColorWithHex(0xffffff) /// 无色 let kCColor = UIColor.clearColor(); let kG1Color = gof_ColorWithHex(0x323232); let kG2Color = gof_ColorWithHex(0x646464); let kG3Color = gof_ColorWithHex(0x969696); let kG4Color = gof_ColorWithHex(0xc8c8c8); // 仅使用标题栏分割线 let kG5Color = gof_ColorWithHex(0xdcdcdc); // 主页面分割线 let kG6Color = gof_ColorWithHex(0xf0f0f0); // 仅用于背景灰 let kBgColor = gof_ColorWithHex(0xf8f8f8); // 界面背景颜色 let kHolderTipColor = gof_ColorWithHex(0xafafaf); // 提示:输入框,这个提示语的颜色 let kButtonBlueColor = gof_ColorWithHex(0x41acff); let kLightColor = gof_ColorWithHex(0x666666); let kGrayTitleColor = gof_ColorWithHex(0x999999); let kGrayTipColor = gof_ColorWithHex(0x757575); let k323232Color = gof_ColorWithHex(0x323232); let k646464Color = gof_ColorWithHex(0x646464); let k969696Color = gof_ColorWithHex(0x969696); let kf0f0f0Color = gof_ColorWithHex(0xf0f0f0); /// 三大色调 let kEssentialColor = gof_ColorWithHex(0x46a0f0); // 主色调,蓝色 let kAssistOrangeColor = gof_ColorWithHex(0xff8c28); // 辅色调,橙色 let kAssistGreenColor = gof_ColorWithHex(0x5abe00); // 辅色调,绿色
3.常用变量/方法定义
import Foundation import UIKit // MARK: - 打印日志 /** 打印日志 - parameter message: 日志消息内容 */ func printLog<T>(message: T) { #if DEBUG print(" \(message)"); #endif } // MARK: - 线程队列 /// 主线程队列 let kMainThread = dispatch_get_main_queue(); /// Global队列 let kGlobalThread = dispatch_get_global_queue(DISPATCH_QUEUE_PRIORITY_DEFAULT, 0); // MARK: - 系统版本 /// 获取系统版本号 let kSystemVersion = Float(UIDevice.currentDevice().systemVersion); /// 是否IOS7系统 let kIsIOS7OrLater = Int(UIDevice.currentDevice().systemVersion) >= 7 ? true : false; /// 是否IOS8系统 let kIsIOS8OrLater = Int(UIDevice.currentDevice().systemVersion) >= 8 ? true : false; /// 是否IOS9系统 let kIsIOS9OrLater = Int(UIDevice.currentDevice().systemVersion) >= 9 ? true : false; // MARK: - 常用宽高 /// 屏幕Bounds let kScreenBounds = UIScreen.mainScreen().bounds; /// 屏幕高度 let kScreenHeight = UIScreen.mainScreen().bounds.size.height; /// 屏幕宽度 let kScreenWidth = UIScreen.mainScreen().bounds.size.width; /// 导航栏高度 let kNavBarHeight = 44.0; /// 状态栏高度 let kStatusBarHeight = 20.0; /// Tab栏高度 let kTabBarHeight = 49.0; //根据图片名称获取图片 let gof_ImageWithName: (String) -> UIImage? = {imageName in return UIImage(named: imageName); }
【注意】:上面的printLog用了条件编译,DEBUG需要在TARGET中配置一下,具体如下图:
