Is there a way to determine the line of code a certain method was called from?

StackI hope that this helps:

    NSString *sourceString = [[NSThread callStackSymbols] objectAtIndex:1];
    // Example: 1   UIKit                               0x00540c89 -[UIApplication _callInitializationDelegatesForURL:payload:suspended:] + 1163
    NSCharacterSet *separatorSet = [NSCharacterSet characterSetWithCharactersInString:@" -[]+?.,"];
    NSMutableArray *array = [NSMutableArray arrayWithArray:[sourceString  componentsSeparatedByCharactersInSet:separatorSet]];
    [array removeObject:@""];

    NSLog(@"Stack = %@", [array objectAtIndex:0]);
    NSLog(@"Framework = %@", [array objectAtIndex:1]);
    NSLog(@"Memory address = %@", [array objectAtIndex:2]);
    NSLog(@"Class caller = %@", [array objectAtIndex:3]);
    NSLog(@"Function caller = %@", [array objectAtIndex:4]);
