Parse text or numbers from a website example

iOS
#1

I thought i would share an example I made for my course for using objective c stuff to pull down text from a website and parse it out indie of ofxiphone.

testApp.h

  
#pragma once  
  
#include "ofMain.h"  
#include "ofxiPhone.h"  
  
class testApp : public ofxiPhoneApp {  
	  
public:  
	void setup();  
	void update();  
	void draw();  
	void exit();  
	  
	void touchDown(ofTouchEventArgs &touch);  
	void touchMoved(ofTouchEventArgs &touch);  
	void touchUp(ofTouchEventArgs &touch);  
	void touchDoubleTap(ofTouchEventArgs &touch);  
	  
	void lostFocus();  
	void gotFocus();  
	void gotMemoryWarning();  
	  
	string NSStringToString(NSString * str);  
	  
	vector<string> fileTxt;  
	  
};

testApp.mm

  
  
#include "testApp.h"

	//iPhoneAlerts will be sent to this.  
	ofxiPhoneAlerts.addListener(this);  
	  
	NSString *urlString = [NSString stringWithFormat: @"[http://www.swpc.noaa.gov/ftpdir/latest/DSD.txt"];](http://www.swpc.noaa.gov/ftpdir/latest/DSD.txt"];)  
	NSURL *url = [NSURL URLWithString:urlString];

	NSString *s = [[NSString alloc] initWithData:data encoding:NSASCIIStringEncoding];  
	  
	fileTxt = ofSplitString(NSStringToString(s), " ");  
	  
	for (int i = 1; i < fileTxt.size(); i++) {  
		fileTxt[i].erase(std::remove(fileTxt[i].begin(), fileTxt[i].end(), '\n'), fileTxt[i].end());
