I did the setup successfully as per http://gabriel.github.com/gh-unit/docs/appledoc_include/guide_install_ios_4.html

Can you please help me out with this road block ? What may be the reason of main project method not able to get called?

In the Target project; do I need to do something extra so that it can recognize all the methods written in main project?

Thanks in advance.

Regards,
Vikram

Good point. The reason was that loadView would create the default self.view, otherwise it crashed. The fix is to change it to the code:

// [super loadView]; // remove loadView call and create a view for the current main screen with resizing masks

UIView *myView = [[UIView alloc] initWithFrame:[UIScreen mainScreen].applicationFrame];
myView.autoresizingMask = UIViewAutoresizingFlexibleHeight|UIViewAutoresizingFlexibleWidth;

“Your custom implementation of this method should not call super.” – Apple documentation

You’re welcome!

Use this function:

NSString* str = [[NSString alloc] initWithBytes:buffer length:sizeof(buffer) encoding:NSASCIIStringEncoding];

If you want to reduce the size of the string use Base64:
