注:以下内容,可查阅 GitHub 中 AMKLaunchTimeProfiler 的 Readme.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-mainmain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

2、Installation

AMKLaunchTimeProfiler 可通过CocoaPods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。

详见:https://github.com/AndyM129/AMKLaunchTimeProfiler

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:

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方式,辅助找出具体的耗时的操作,进而通过优化 实现提速冷启动,相关方法如下:

```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 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, ...;

```
