[![Platform](https://img.shields.io/cocoapods/p/AMKLaunchTimeProfiler.svg?style=flat)](https://cocoapods.org/pods/AMKLaunchTimeProfiler) ## 1、Features * **零成本使用：** 通过 CocoaPods 一行代码接入，即可实现 APP 冷启动耗时统计，包括 `pre-main`、`main`、`首屏渲染`三个阶段的耗时，及总耗时 * **可视化查看：** 内置日志查看页面，并自动高亮高耗时方法，各种信息一目了然 * **源数据导出：** 可以方便的通过邮件、AirDrop 等方式 导出全部数据，具体包括 * 日志列表的文本数据，方便在电脑上查看 * 日志的JSON数据，方便基于日志的执行时间、调用方法、执行耗时 等信息 做自定义分析 * 多次有效数据的平均数 数据 | ![31287f21b40610de7ca62a16bbcbe05f](README.assets/31287f21b40610de7ca62a16bbcbe05f.jpg) |

`AMKLaunchTimeProfiler` 可通过[CocoaPods](https://cocoapods.org)完成引入，仅需现在工程的`Podfile`文件中 添加如下代码 ``` pod 'AMKLaunchTimeProfiler' ``` 然后在终端在`Podfile`文件所在路径下执行 `pod install`命令即可完成源码下载与引入。 ## 3、Usage ### 3.1、查看相关日志 内置日志查看页面，并自动高亮高耗时方法，各种信息一目了然，具体可通过如下方式打开： #### 3.1.1、使用手势 通过 `AMKLaunchTimeProfiler.debugEnable = YES;` 启用调试模式（默认不启用），即可在 任意界面，通过「双指从右向左轻扫」的手势打开 #### 3.1.2、使用编码 通过 `[AMKLaunchTimeProfilerLogsViewController.new presentingWithAnimated:YES completion:nil];` 使用代码打开 每一次启动，都会新创建 并保存一个 `AMKLaunchTimeProfiler` 实例，相关日志也都会存在该实例中，并实时持久化到本地，举例如下： ```

```objective-c /// 打印日志 #define AMKLaunchTimeProfilerLog(FORMAT, ...); /// 打印日志 - @"开始..." #define AMKLaunchTimeProfilerLogBegin(FORMAT, ...); /// 打印日志 - @"结束" #define AMKLaunchTimeProfilerLogEnd(FORMAT, ...); /// 打印日志 - 内部日志 #define AMKLaunchTimeProfilerInternalLog(FORMAT, ...); /// 打印日志 - 相同位置 只打一次 #define AMKLaunchTimeProfilerOnceLog(FORMAT, ...); /// 打印日志 - 相同位置
