My program is terminating I'm not able to flash the source code.
If any of you have any solution please suggest how to solve this
Thank you
I'm new with Ios programming Objective-C language and my app was working great until suddenly stop working and get this error
Xcode show me a generic error and i want to know which function or instruction produce this error i couldn't find how to do this with Xcode i want just to point the problem where it may come from
This is the error i got :
Add Exception breakpoint
As shown in the image, select the 8th tab(Exception) and from the below add button, add the Exception Breakpoint. This will show the exact line of code from where the application crashes.
Add Exception breakpoint
How to create exception breakpoints in Xcode?
Exception breakpoints are a powerful debugging tool that remarkably
few people know about, so please read the following carefully and put
it into practice!
A regular breakpoint is on a line you specify and causes the debugger
to pause execution at that point so you can evaluate your program's
state. An exception breakpoint tells the debugger to pause whenever a
problem is encountered anywhere in your program, so you can evaluate
your program's state before it crashes.
Exception breakpoints are trivial to set up: go to the Breakpoint
Navigation (Cmd+8), then click the + button in the bottom left and
choose Add Exception Breakpoint. You can leave it there if you want
to, but it's preferable to make one further change to reduce
unnecessary messages: right-click on your new breakpoint, choose Edit
Breakpoint, then change the Exception value from "All" to
"Objective-C".
Please follow the below steps.
Run your project.
When i enable all exceptions breakpoint my app always stops in AppDelegate, but im able to continue the program execution, but its very annoying cause always takes me to the appdelegate. Any ideas why?
Only enable Objective-C breakpoints.
To see the actual statement that is causing the error add an exception breakpoint:
From the Main Menu Debug:Breakpoints:Create Exception Breakpoint.
Right-click the breakpoint and set the exception to Objective-C. This will ignore other types of exceptions such as from C++. There are parts of the APIs that use exceptions such as Core Data (Apple is Special).
Add an action: "po $arg1".
Run the app to get the breakpoint and you will be at the line that causes the exception and the error message will be in the debugger console.
Breakpoint example:
If you're using Swift, or you want to have all the exceptions captured, you can change an option on All Exceptions to automatically continue after evaluating actions. Just find it in the Breakpoint Navigator and right/ctrl click the all Exceptions Breakpoint to edit it:
Then check the Options box:
Exceptions in C++ code common and normal. The exception breakpoint catches every raised exception even when they are being handled correctly. So if you don't specify Obj-C only you will notice that execution stops in a lot of seemingly random places. I run into this all the time with AVAudioPlayer especially.
Another thing to look out for are missing assets. I came across this question from another asker who seems to have also run into the same issue.
Xcode throws an exception in Main() in iOS 8 with 'all exceptions' breakpoint
I am using XCode 4.5 with LLVM. In older versions of XCode, when there was a crash it would give me meaningful debugging information. Lately I keep getting crashes that simply say "libc++abi.dylib: handler threw exception," and don't provide a stack trace that shows where the exception came from. This is totally useless to me. What are the proper debugging settings that I should set up so that I can find the location of the problem?
you could add a breakpoint and set it to break on all exceptions
My project complied fine. But when I am running application in debug mode, I'm getting many runtime errors each time regarding resources. How can I resolve this?
EDIT
the Actual error is "project raised exception class EResNotFound with message 'Resource WW_DBN_PRIOR_ENABLED not found'
