iphone console leak instruments xcode-instruments
I’m running the Mac OS “Instruments” app, using the “Leaks Instrument” to monitor an iPhone app. The major pane is titled “Leaked Blocks”, but if you click on that you get a choice of three: “Leaked Blocks”, “Call Tree”, and “Console”. Click on “Console”.You now have a blank pane … click in it and hit . In my case, I get:foo (4259) >which is my app name and, presumably, the PID it’s running as.I can enter commands/text (e.g., ls, help, exit) … they get echoed after awhile but nothing else

ios profiling instruments xcode-instruments
I really like developing for iOS more than Android. However, android SDK has a great tool for profiling, called Traceview:It can not only help to find bottlenecks, but can also show which method was running in specific moment in each thread. This can be very helpful in profiling and debugging. For example, if my app crush at some moment, I can easily see what was happening before the crash in each thread.Is there are any tool for iOS that can do similar things? I tried TimeProfiler and Sampler i

iphone xcode4 xcode-instruments
When I used Instruments tool to monitor my memory usage, I found a process named DTMobileIS use about 40% of real memory, and then there were not enough memory for my app so it crashed. I am curious about this DTMobileIS means for. Does anyone know about it?Edit: It seems like DT is the prefix of Debug Tool. And according to this link, IS sounds like the abbreviation of Instruments.

c# ios monotouch monodevelop xcode-instruments
I’m making an iOS game in Monotouch with C# and MonoDevelop. I’m having a very strange crash. Background Information: Making a 2D war game. I’ve implemented Dijkstra’s algorithm to calculate the shortest path from source to destination with objects in-between (example: go from here to there but go around the cars/trees/buildings/or anything in the way automatically). My crash seems to be related to the 2D array of bytes that I created for this implementation of Dijkstra’s algorithm. See th

ios xcode xcode-instruments
Our app runs fine. In Instruments (on the simulator), when trying to profile memory, under Allocations I see Overall Bytes rising very fast, while Live Bytes remain small. There are no leaks and VM usage seems stable (if large).This is not a show-stopper, but makes profiling that much more difficult. Any ideas?Thanks!

My app crashes on the iOS 5 iPad simulator after about 5 min of smooth running. This is the only crash reference I get from Xcode, when I try to do a profile run using zombies/memory leak, the app for some reason won’t even load (splash-screen shows and then the app crashes), I have no clue what is causing this behavior, any ideas?error: memory read failed for 0x0More info: I use ARC, the app works well on iOS6 & iOS7
