Image尺寸太大，導致渲染的時候佔用太多內存，造成App卡頓 — 最近寫了一個demo專案，使用SE2的時候跑得很順，用iPhone8跑卻會Lag，播放影片會卡頓，仔細一看，當下Memory竟然飆到兩百多MB！ 打開Instruments監控了一下，完全沒有出現memory leak，研究了一下Allocations，發現是GPUImage使用了過多的memory Instruments筆記 記得打開dSYM才比較好分析哪裡有問題唷 关于xcode：使用Instruments分析iPhone应用程序时缺少符号名称 我正在通过命令行编译iPhone应用程序(因此不涉及XCode选项)，并且在使用Instruments进行性能分析时无法显示符号名称。 我尝试了几个标志，例如-gdawrf-2和-g，但没有成功。…www.codenong.com Allocations的介紹 Instruments学习之Allocations 注意：这个工具非常有用，文本也是一个超长文 Allocations：检测一个进程（选择自己的app）内存分配和使用情况等 我们启动Allocations后得到一个初始界面 简单说一下上图的3个地方…www.jianshu.com
