Anyone know.. what is this? "jvm error 104 uncaught classcastexception" this message shown in my simulator simulator blackberry 9550? thanks.
I believe that an Exception is occurring when you are trying to cast an object with a class.. I had a similar issue and that was the problem I found.
You haven't shown a single line of code, but I'll hazard a guess: you're trying to cast an object to a type which it does not subclass.

Hi whenever i run my ios app in the simulator i get the error Fatal error: attempting to create attribute with no subgraph: CachedView<KFImageRenderer, ImageBinder> (lldb) . however, the app seems to run fine in the preview. Does anyone know a fix for this issue?
In my case I had forgot to add the .environmentObejct(..) to the previews section. Also got it fixed by adding the environment to my preview.
The application works fine on the simulator but breaks in start up in device as in the figure
I tried some of the solution in SO but It doesnt work out.What may be the reason ?How can i find it? How to resolve it
For clarity
Tried : Changing the view controller the viewcontroller. view did load and all functions are working fine after that when the view tries to appear on the screen the crash appears
UPDATE : Now getting the error logged as
*** -[Not A Type retain]: message sent to deallocated instance 0x208c9610
I had the same issue before. This is not a crash. Please remove all your break points and run it again.
This is a Breakpoint error ..... It normally occurs when you add a breakpoint to an app running in the device. If you add the breakpoints before the app has been built and run it again.... The crash will not occur.
Even I couldn't figure out why this crash should occur in the first place but it does.
OK found out the problem.I am using an external library which does not implement ARC so it has to be flagged.all files except 2 are not flagged as -fno-objc-arc and hence the issue.
I am new on ios and i am following a tutorial to develop a calculator.
When i build my project it succeds, but on run time it crashes and throwa an exception:
`2012-09-19 10:03:51.469 AhsanCalculator[325:f803] *** Terminating app due to uncaught exception 'NSUnknownKeyException', reason: '[<ViewController 0x6d59870> setValue:forUndefinedKey:]: this class is not key value coding-compliant for the key pushOperand.'
*** First throw call stack:
My code is here if you need more detail. Tell me what you need and i will give you all the details.
Xcode = 4.3.3
5.1 iPhone simulator
Please help to solve this issue
The crash occurred for you is because, in your xib you have linked/connected some wrong objects, i mean a UITextField to a UITextView or some thing like that.
When you open Xib right clicking on the files owner object, it shows some of the IBOutlets connected with a warning icon, delete those and connect to the right/correct one.
This will clear your crash, and works fine.
As you are new to iOS development, here are some link to learn about what to when a crash appears in the project,
Its is by Raywenderlich, here it is a 2 part tutorial part 1 and part 2.
I am working on an iPhone application in which I have to design a GridView, I have searched on google + stackoverflow and found that one possible solution is AQGridView, I have tried it but all of its examples are not working in XCode 4.1.
The error I am facing is: Expected ':', ",", ";", "}" or 'attribute' before '_dataSource'.
The line causing this error is id<AQGridViewDataSource> __unsafe_unretained _dataSource; (line no 100 in AQGridView.m).
What I am trying to achieve is to display buttons in 2x4 table.
Any Help will be appreciated.
Thanks
Edit
Ok, so I have downloaded Xcode 4.2 as some guys suggested in comments, now the previous errors are gone but I am having a new on __bridge Undeclared (first use in this function), the line causing this error is line no 961 in AQGridView.m (Source Code)
Thanks
First create a gridview objective class.write own delgate and datasource methods as tableview in it.call it in the viewcontrler class.
I think, on XCode 4.2 this is not an issue.
XCode 4.1 does not know __unsafe_unretained.
So just define it in some global project header:
#define __unsafe_unretained
and try to compile again.
Everytime I quit the app in the simulator.
The console display this error message:
*** -[NSThread _nq:]: message sent to deallocated instance 0x6d770e0
Looks the app try to access an deallocated instance.
But I cannot find it anyhow, even using the instrument.
I can't find the line of code that cause the problem.
p.s. I have already tried any ways that I know to debug this problem. but no success yet.
I enabled NSZombie and use instrument to help me to find out the error. But the error report did not point to any of my own code. I have no idea why this happen.
Double click on your executable in the left pane in XCode, go to the arguments tab, add a new one named NSZombiesEnabled and set its value to YES. This will set all deallocated instance to an NSZombie and you'll be able to tell what type is being deallocated.
NOTE: THis must be turned off after or your app will never release memory!
Fixed, this problem is that I access interface objects not in the main thread. you can do so by [self performSelectorOnMainThread....].
