Confused about try-catch

[Danneman]

Im confused over how try-catch works in ObjC. In C#, for instance, when something goes bananas inside try-brackets the catch-brackets replaces that code assuring the program wont crash.

In objc however, Im able to actually crash an app from within a try-bracket, like such:

	@try {
		for (int i=0; i < [self.strArr_Const_RowTitles count]; i++)
		{
			NSLog(@"TITLE: ");
			NSLog([self.strArr_Const_RowTitles objectAtIndex:i]);
		}
	}
	@catch (NSException * e) {}

This code manages to crash the app at various instances. Im not as interested in whats wrong with the actual code inside the try-statement (sure, any ideas are welcome) as I am to the cause to why the execution of the code doesnt revert to the try and jumps to catch when it fails.

Are you sure that the code in the try-brackets really fires a NSException object? May be the code causes an error but not an exception?

Take a look at this simple example:

@try {
    NSException *exception = [NSException exceptionWithName:@"HotTeaException"
        reason:@"The tea is too hot"  userInfo:nil];
    @throw exception;
}
@catch (NSException *exception) {
    NSLog(@"caught %@: %@", [exception name], [exception reason]);
}
