This is my first try in moving my app to a device. I was able to launch the app by clicking on the start button on XCode to launch it on my iPhone. I stopped the app and see if I want to try whether I am able to run it without being plugged. I can still see the app icon on my iPhone but when I launch it.. it immediately closes. What am I doing wrong?
I fixed the error, it was a stupid %# where I need %f.
First delete your application from the device and run again your application from the XCode on the device and run it thoroughly while the device is connected and then try to run the application. It should then work.
It is not related to provisioning. Environment is different when the program is being debugged. Plug the iPhone back to computer and check the crash log in XCode > Organizer > Device > Device Log.

I have an app in ad-hoc mode and it crash right after starts. I have access to Xcode and i try to find crash log like here: iPhone crash log?
But i have no crash log from this app. Why?
Right after app starts i can see Default.png and few second later it crash, i've never even see the mainViewController. How do get a crashlog? How to detect this error? I don't have an access to source code. I have only ad-hoc distribution.
Problem not occurs on every devices. AFAIK this is only 3GS problem. Strange.
Instead of looking for the crash log, try connecting your phone to xcode but look at the Console screen instead, run the app and you should see output on the console, see if you get an error message there.
For users who don't have access to Xcode or are running on a PC you can download Apple's iPhone Configuration Utility which also gives you access to the device console.
I have developed an application on iPhone.
If i run it from XCode, no problem : XCode installs the app on the device, then the app is running, OK.
But then, I unplug the device from Mac, and i run the app : crash happens, OK.
I would like to know if there is a way to attach XCode as debugger when I run an app from the device, and not from XCode. Such like Windbg and dump of application crashed.
If you re-attach your device to XCode, you can access the crash log.
Go to the Organizer, select Devices, select your device, and then under your device name, you will see "Device Logs". You will be able to select and examine any of them in the next window to the right.
You will also be able to see the Console.
These should help in determining what caused the crash.
I think this is mostly due to memory issue. Check in instruments that your application consumes more memory. If so try to reduce memory conception by releasing unnecessary view controllers and mostly UIImageViews
i have run my application in device but application is crashed and print following message
error from debugger: the program being debugged is not being run.
so please tell me what to do?
my application gonna launch properly but not not debugging first time (gonna crash) than from second time i start application work proper without crashing
my application install in device. we can`t debug in device...
The first thing i do when i get that is a Clean All usually solves that. If you don't see the Clean All button right click your Xcode toolbar, customize, and drag the Clean All button to your toolbar from there.
-Check that the provisioning profile installed on your device haven't expired (would see a red dot in the organizer - Window->Organizer).
-Try restarting XCode.
Do you mean device? If so then it could mean the device is not launching the application correctly. Make sure your developer profile and everything in the build settings is correctly set. This may sound obvious but also make sure the device is unlocked and open.
When I run my app with simulator every thing is ok.also when i run it on device (ipod touch 3G) for the first time,i have no problem but if i close my app and run it again,it hangs(no button working & just i can uninstall it) and if i try to minimize it ios seems out of action(every thing is being black)
how can i solve this problem ?
Run your application in the simulator with the profiling tools, making sure you check for allocations / releases and if there are any network resources left open.
You haven't said anything about what your app does to give any more help than that, but the development tools will tell you what is going on.
Also when you connect to the iPod, check the crash reports to see what happened
have u release any object in appWillTerminate. may be u trying to release object that is already released before the application quit. or u can see the application quit status in nslog if status is not 0 means application is not quitting properly.
I currently have it set up for Xcode to Build & Go onto my iPod using this: http://il.youtube.com/watch?v=CHOVdi-kPV0 (A script to tell Xcode that it doesn't need to codesign). This works, except when the app launches, it closes instantly and Xcode says it failed to launch. You can manually reopen the application and it works 100% after. The problem is I need to be able to build & go through Xcode, and have the application stay open so I can debug on the device. Does anyone have a way to do this?
I followed this guide and it worked for me: http://www.alexwhittemore.com/?p=354
