AMKLaunchTimeProfiler
—— 简单、易用、强大的 iOS APP 冷启动耗时分析工具
注：以下内容，可查阅 GitHub 中 AMKLaunchTimeProfiappleler 的 Readmgit教程e.md 以获取及时更新，和更好的阅读体验~~
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jsonobject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
 |
 |
 |
 |
 |
|---|---|---|---|---|
| 可视化查看 | 操作选项 | 源数据导出 | 通过邮件导出 | 通过其他方式导出 |
2、Installation
AMKLaunchTimeProfiler 可通过CocoaPods完成引入，仅需现在工程的Poappeardfile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。
详见：github.com/AndyM129/AM…
3、Usage
3.1可视化音乐、查看相关日志
内置日志查看页面，并自动高可视化大屏亮高耗电脑时方法，各种信息一目了然，具体可通过如下方式打开电脑蓝屏：
3.1.1、使用手势
通过 AMKLaunchTimeProfiler.degitibugEnable = YES; 启用调试模式（默认不启用），即可在 任意界面，通过「电脑快捷键双指从右向左轻扫」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：

3.3、自定义日志
对于耗时较高的方法，可以通过补充自定义日志的可视化大屏方式，辅助找出具体的耗时的操作，进而通过优化 实giti轮胎现提速冷启动，相关方法如下：
/// 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 只打一次 - @"开始..." #define AMKLaunchTimeProfilerOnceLogBegin(FORMAT, ...); /// 打印日志 - 相同位置 只打一次 - @"结束" #define AMKLaunchTimeProfilerOnceLogEnd(FORMAT, ...); /// 完全自定义的日志 - (void)logWithFunction:(const char *_Nullable)function line:(NSInteger)line string:(NSString *_Nullable)format, ...;
