How to log all methods used in iOS app

由 别说谁变了你拦得住时间么 提交于 2019-11-26 14:06:16
I'm taking over the development of an iPad app for a client. There's a substantial amount of work that's already been done and I'm trying to piece together how the whole thing is designed to run. One of the things I'd like to do is log which methods get called when the app runs. I've seen a custom DTrace script that's meant to log all methods from startup, but when I run it in Instruments I get no results. What's the best way of logging the methods? Brad Larson Inspired by tc's answer to a similar question here , I put together a debug breakpoint action that will log out the class and method

问题 Of all the Instruments Trace Templates, I love using: Zombies to detect where an object is getting over-released, great for debugging EXEC_BAD_ACCESS errors. Leaks to detect memory leaks. Core Animation w Color Blended Layers to detect frame rate & translucent subviews, great for smoothing up UITableView scrolling. I always hear people saying to profile my app\'s memory usage & performance. Why should I profile memory usage & performance? My app runs fine. How do I do it? I\'ve used

Trying to read a Xcode Instruments .trace file. What is the file format of a .trace file?

问题 I am writing an automated profiling system, to profile different GPU intensive screens in my App. I have been trying to use \'XCode Instruments\' for this, with the \'OpenGL ES Driver\' instrument that captures the gpu usage data. My automated system runs Xcode Instruments from the command line which runs the App, profiles and captures the data, and writes the data to a \".trace\" file. I now want to be able to open the trace file, and read the trace data using my automated profiling system,

问题 I have been trying to perform some OpenGL ES performance optimizations in an attempt to boost the number of triangles per second that I\'m able to render in my iPhone application, but I\'ve hit a brick wall. I\'ve tried converting my OpenGL ES data types from fixed to floating point (per Apple\'s recommendation), interleaving my vertex buffer objects, and minimizing changes in drawing state, but none of these changes have made a difference in rendering speed. No matter what, I can\'t seem to

Missing symbol names when profiling IPhone application with Instruments

由 早过忘川 提交于 2019-11-26 09:18:21
问题 I am compiling an IPhone application via command line (so no XCode options involved) and I am unable to get my symbol names to show when profiling with Instruments. I have tried several flags such as -gdawrf-2 and -g without any success. I have also tried using dsymutils to generate a .dSYM file but i have no clue how I\'m supposed to use it so that failed aswell. Any help will be greatly appreciated! 回答1: I Changed my project settings to not include the dSYM file while building: Changing it

问题 Is it possible to track the allocation and deallocation of my Objective-C objects? For instance if I have a class Book, I want to track all the allocations and deallocations of the objects of Book type.

If you use the
