Linking OpenCV iOS
------------------
Follow this step by step guide to link OpenCV to iOS.
1. Create a new XCode project.
2. Now we need to link *opencv2.framework* with Xcode. Select the project Navigator in the left

*Hello OpenCV iOS Application*
------------------------------
Hello OpenCV iOS Application
----------------------------
Now we will learn how to write a simple Hello World Application in Xcode using OpenCV.
- Link your project with OpenCV as shown in previous section.
- Open the file named *NameOfProject-Prefix.pch* ( replace NameOfProject with name of your
project) and add the following lines of code.
@code{.cpp}
#ifdef __cplusplus
#import <opencv2/opencv.hpp>
#endif
@endcode
![image](images/header_directive.png)
@code{.m}
#ifdef __cplusplus
#import <opencv2/opencv.hpp>
#endif
@endcode

- Add the following lines of code to viewDidLoad method in ViewController.m.
@code{.cpp}
UIAlertView * alert = [[UIAlertView alloc] initWithTitle:@"Hello!" message:@"Welcome to OpenCV" delegate:self cancelButtonTitle:@"Continue" otherButtonTitles:nil];
[alert show];
@endcode

@code{.m}
UIAlertView * alert = [[UIAlertView alloc] initWithTitle:@"Hello!" message:@"Welcome to OpenCV" delegate:self cancelButtonTitle:@"Continue" otherButtonTitles:nil];
[alert show];
@endcode
