I am using xcode Instruments to track Allocations and Leaks. My app is crashing though. It does not crash when running the regular debug or release builds standalone, only when under Instruments:
Any thoughts ideas very gratefully received....

Try running it through the analyser first. You can run it from xcode from the |product| menu then select Analyze. It's a static analyser (clang) that analyses your code when it builds so any problems causing your code to crash at runtime could well be visible through static analysis. Give it a try and fix any problems it throws up then try instruments again.
As a complement to what Ian says above:
set the Environment variable "NSZombieEnabled" to YES
and you will hopefully have a more informative fail.
(In XCode 4 the Environment Variables is found under "Edit Scheme" and select "Debug")

I am getting this crash randomly. I tried to check each line of code but i couldn't find any solution. Please suggest something to solve this. I am getting this crash in ios8.1 only.
This often occurs when the reference to the receiving object gets invalid.
Start with a static analysis of your code. Most of the times you can let Xcode do it for you through the Product -> Analyze tool. Also try enabling zombie objects while debugging through editing the current scheme going through Product -> Scheme -> Edit Scheme and check the appropriate box in the Diagnostics tab. Once enabled you have to wait for the crash to occur again if you don't know how to reproduce.

I am struck this issue last three days.
I only replace the video files in my existing code, but if i replace all the video files my application will crash in iphone. it is an universal application but Ipad support all the new video files and crash on iphone. the following warning occur:

Somebody has an idea, please help.
By the crash log we see that, inside -[Visionaries_ViewController connection:didReceiveResponse:], you are calling the method setLength: on an object that does not have that method.
Can be a memory or logic problem. Please provide more info.
I need your help to understand what's going on in this crash log for my app on iPhone 4S.

This link to a discussion in Developer Forums seems to imply bad hardware!?
A little confused!
Thanks.
Your question is a dupe of many other questions that involve EXC_BAD_ACCESS crashes.
Like this one:
how to understand Crash Log of iPhone
Why not step through your program and see if you can isolate where the crash is triggered?
The article you linked is talking about a Macintosh error with Safari, totally different than what you are experiencing.
I'm trying to create a multi-view iOS (4.3) application in xcode 4 using the view-based application template but have so far had no luck. Everything builds but then crashes without error, with me getting the message SIGABRT in the line "int retVal = UIApplicationMain(argc, argv, nil, nil);" in supporting file-> main.m
The same thing happens in both my application and the plain (view-based application ) template from xcode.
Any ideas what the problem might be?

It's telling you that UISplitViewController is not supported on the iPhone - only works on the iPad.
