instruments

问题 If I open Instruments and select a standard application (e.g. Mail or MS Word) it has no issue. If I am in Xcode and I go to Product > Profile (or press Cmd + I ), it launches Instruments, allows me to select a template, and loads the standard screen. Then the downward arrow starts tracing to the right as it should, and the iOS simulator launches the program. However, nothing is plotted in Instruments. It shows no changes to anything no matter what the app is doing. I can't click anything in

问题 We have an app that we run automation tests on with Appium. We can launch the app on the device and simulator through Appium. However, the app hangs and freezes after Appium sends 2-3 tap commands. After the freeze, Appium can not find any other elements on the screen. We looked into writing a test script using Xcode 6.0.1 Instruments, but when the script is run, the app hangs as well. The app performs as expected when testing manually. It only hangs when we try to run automation on it either

问题 I use a continuous integration tool that builds an app using a Distribution identity and an Ad Hoc mobile provision. This app is sent on a web site for ad-hoc deployment and everything works well. But now I would like to add a step in my build workflow to execute UI Automation tests. Instruments needs an app signed with a Developer identity, so instead of building a new version of the app signed with a developer certificate, I want/need (Q.A. team wants actually) to resign the previous

问题 Environment iOS 9.2 Xcode 7.2 I'm looking to replace the UIWindow's rootViewController with an animation while also removing it from the view hierarchy as well. class FooViewController: UIViewController { } class LeakedViewController: UIViewController { } Then initiate the transition in the AppDelegate simply by self.window!.rootViewController = LeakedViewController() let fooViewController = FooViewController() self.window!.rootViewController?.presentViewController(fooViewController, animated

问题 My app crashes on devices with 0.5GB memory. However, profiling memory usage in Xcode - it rarely goes above 140MB. I've used instruments to check leaks and there are none that are significant. However, when I run my app, the memory used by 'Other Processes' is always very high. This is the resting state after launching: I added a 1 second delay in each cycle of a loop in my code, and discovered that on each loop, the 'other processes' increases memory usage by about 3MB per object, until on

问题 I'm trying to profile a large C++ application with Apple Instruments. I also wanted to do it WITHOUT building an Xcode project/workspace around my project (since I have an insane amount of dependencies / libraries / makefiles already set up). To do this I launched Instruments from Xcode/Contents/Applications/Instruments and selected a time profiler. For my target, I set it to my binary I wanted to profile. I then set the working directory to where my project files are (and the subsequent dSYM

问题 For opening Instruments we must profile first then select which template we have to profile memory leaks,allocations,zombies. But still I get the error allocations library was not loaded, and could not see the stack trace also. And could not find the reason of leak in the application As mentioned solution in other links, I am using both simulator (iOS7), and active scheme (iOS7) Xcode Version:Version 5.0.2 (5A3005) Simulator: iOS 7.0.3 (111B508) Mac: OS X Version 10.8.5 Please excuse if any

问题 I'm trying to find another memory leak in my code, and I can't seem to figure out what CG Raster Data is. While going through the VM Tracker with automatic snapshots enabled, the CG Raster Data seems to be the only part that increases. These also increase steadily without the allocations increasing. I'm not entirely sure what the CG Raster Data is, nor how I would fix it, but at this point the increasing footprint eventually causes a memory error and crash, so it's not good! I do my own text

问题 I've created a universal binary using iOS 4.2 and Xcode 3.2.5. I'm trying to do some automation testing on the application and since the interfaces are slightly different between the iPad and iPhone versions, I have separate UIAutomation scripts. Unfortunately, no matter what I do, when I click the record button in Instruments, it always starts the application using the iPad simulator. How can I force Instruments to launch the iPhone simulator? The universal app runs fine in the simulator for

问题 In previous versions of Instruments I had no problem but now (v6.2) for some reason Allocations won't list any of my app's objects. I've tried Debug and Release Mode: Note, the filter "VC" should catch all the ViewControllers. And without the filter... Any ideas? 回答1: I tested this out with both 6.2 and 6.3 and encountered the issue. Also I was using the iOS 8.2 and 8.3 simulators. However, when I switched to the iOS 8.1 simulator, it worked properly. So it's not so much a bug with
