signal SIGARBT error - ios

Question

I get this error if I'll run my App in the iOS Simulator (iPhone 4-inch 32-bit iOS 7.1):
Thread 1: signal SIGABRT
Error:
int main(int argc, char * argv[])
{
#autoreleasepool
{
return UIApplicationMain(argc, argv, nil, NSStringFromClass([AppDelegate class]));
}
}
I hope someone can help me.

Answer 1

Filter1 in a class called ViewController doesn't exist. You may have deleted an outlet or something from the code, but forgot to delete the link from the actual object in the storyboard. Right click on what was linked to Filter1 and see if it has the old (deleted) connection still.

Answer 2

It looks like you setup a button with an action of filter1: but you never added the filter1: method to your ViewController class.
Perhaps you defined the method as filter1 instead of filter1:. The colon makes a huge difference.
If your method is really:
- (IBAction)filter1 {
}
Then you need to change the button to use the selector filter1 instead of filter1:. Or change the method to:
- (IBAction)filter1:(id)sender {
}
