instruments

问题 When profiling my app with Instruments (looking for memory leaks), I get extremely different results with the iOS 5 iPhone Simulator from those I get with my iPhone 4 running iOS 5. The first picture shows the results from the profiling with the real device, and the second is with the simulator: Real device: iOS 5 Simulator: This profile is taken up to the same point in the app in both cases: completion of viewDidLoad in the rootViewController's view lifecycle. I have waited in both of them

问题 I have found some big memory leaks with instruments but have no idea how to figure out where in my code they are. Need some tuts on how to go about that.... 回答1: Sounds like you need to do this: IPHONE: Analyzing leaks with instruments. It's not obvious from the Instruments' documentation. 回答2: Duplicate question, but here is a good tutorial. http://www.mobileorchard.com/find-iphone-memory-leaks-a-leaks-tool-tutorial/ Also, here's a link to the original question: How do you detect memory

问题 I'm facing this weird problem in UIAutomation. I am checking an alert. In that, I am trying to log alert title and alert message. My code for this is: UIATarget.onAlert = function onAlert(alert) { UIALogger.logMessage("alert Shown"); UIALogger.logMessage(frontApp.alert().name()); UIALogger.logMessage(frontApp.alert().staticTexts()[1].value()); } var target = UIATarget.localTarget().frontMostApp().mainWindow(); target.scrollViews()[0].buttons()["saveB"].tap(); UIATarget.localTarget().delay(2);

问题 Hi: In an iPhone application I use a library(C++) which asynchronously makes a callback when computation is finished. Now I want to measure the time which is spent -including the method which calls the library- until the callback is made. Are there any possibilities to do this with the Instruments application from Apple? What are the best practices? 回答1: In the past I have used the following for making network calls I had to optimize - although at first it seems a bit convoluted, it certainly

问题 Until very recently, instruments worked fine. I don't know what I did to make it mad, but now it won't attach to any device that I try to Profile with; no device at all. I've tried an iPhone, iPad, and 2 iPod touches; no luck! I'm using XCode 4. Here is the sequence of events: With device attached, click Product->Profile. App compiles onto device. Instruments launches, but an error sound is heard The record button is grayed out. Choose Target doesn't allow me to attach or choose target (empty

问题 I am using instruments and seeing this: # Address Category Timestamp Live Size Responsible Library Responsible Caller 4 0xd84ba00 Malloc 10.00 KB 00:01.896.732 • 10240 libRIP.A.dylib RIPZoneDataAlloc What is RIPZoneDataAlloc and the libRIP.A.dylib? It seems to be taking up a large portion of the memory. Is it a symptom of something bad? I am using ARC and i0S 5. Thank you. 来源： https://stackoverflow.com/questions/9507212/ripzonedataalloc

问题 I am developing my first iOS app and I am almost ready to submit to app store. However, I am having problems with launch time. It is taking ~3 seconds to launch. The app has a ContainerView with three UIViewControllers as Child View Controllers. The middle UIViewController is a camera and the left and right UIViewControllers are mostly made up of UITableViews that make basic network queries (not on main thread) to populate them. Basically, I am trying to figure out why my app takes 3 seconds

问题 I am using the following script to run leaks instruments from the command-line. instruments -t /Applications/Xcode.app/Contents/Applications/Instruments.app/Contents/Resources/templates/Leaks.tracetemplate <app path> after executing the command, i get instrumentscli0.trace file. How can i get readable data about leaks from that file. Is there any way to export the results to a text file via any command. In automation template we can specify an output folder using the switch -e UIARESULTSPATH
