I'm calling methods dynamically by name. this is the code I'm using:
NSString *methodName=[NSString stringWithFormat:#"%#HintButton",stringForPredicate];
SEL s = NSSelectorFromString(methodName);
[self performSelector:s withObject:hItem];
I Checked and s value is
AnotherSoundHintButton
I have the following method in my code:
- (void )AnotherSoundHintButton:(HintItem*) hItem {
[self PlaySound:hItem.hint];
}
but when I run my app I'm getting the following error:
2013-05-29 12:18:39.945 Game[19668:c07] -[SoundViewController AnotherSoundHintButton]: unrecognized selector sent to instance 0x8c60e90

Try this :
NSString *methodName=[NSString stringWithFormat:#"%#HintButton:",stringForPredicate];
The colon after "HintButton" is important.
add column(:) after AnotherSoundHintButton

So, I'm having problems with my code.
It runs smoothly with iOS8 but when I run iOS7.1 simulator or run it through an iOS7.1 phone, I get this error.

The error occurs at the first line of appdelegate:

My app imports corelocation, foundation and contactlist.
Check all the methods called in your ViewController (viewDidLoad method) you probably have a selector only available on iOS8.
To check the availability you can just right click on the method and check the documentation.
Here is an example for the showViewController:sender: method.

I am testing my app out, pushing it pretty hard, and I'm getting it to crash (black screen, image doesn't save, drops back to springboard). However, I get no crash reports logged in the console. When I test using profiler all I get is a message saying the target died, but it gives no clues.
In the organiser I got the device crash logs which gives me this which I believe is telling me I'm sending a message to something I've released (objc-msgSend + 22)? Am I on the right track here?

If you suspect that you are overreleasing something, try running your app with NSZombie enabled. (how to enable NSZombie)
You can set exception breakpoint to print backtrace in console.
sometimes that happens when you set an object as an observer for notifications, like
[[NSNotificationCenter defaultCenter] addObserver //details
and don't remove it from the observers list when it's released.
the system tries to send a message to it, and the app crashes because it's not there.
try adding
[[NSNotificationCenter defaultCenter] removeObserver:self];
in the dealloc function. (even if you're working with arc, create a dealloc function, and write that in it).
good luck
I'm trying to better understand what the stack trace means. I have a two specific questions in this case.
1 - Does this stack trace mean that the method setOutcome: is unrecognized by an instance of a Task object?
2 - Can a method be unrecognized if the parameter passed in does not match the class of the expected parameter?

Yes
No, but you would probably get an unrecognized selector error from within that method once you try to do something with it - e.g. if you are expecting an array and you pass in a string, then try to get an object from your "array", you will get an error at that point.
