get name of currently connected WiFi network

  CFArrayRef myArray = CNCopySupportedInterfaces();
  CFDictionaryRef myDict = CNCopyCurrentNetworkInfo(CFArrayGetValueAtIndex(myArray, 0));
  NSDictionary *ssidList = (__bridge NSDictionary*)myDict;
  NSString *SSID = [ssidList valueForKey:@"SSID"];
  NSLog(@"%@",SSID);

open Settings from your app

[[UIApplication sharedApplication] openURL:[NSURL URLWithString:@"prefs:root=WIFI"]]; [[UIApplication sharedApplication] openURL:[NSURL URLWithString:UIApplicationOpenSettingsURLString]];

• http://stackoverflow.com/questions/8246070/ios-launching-settings-restrictions-url-scheme
• as of iOS8 you can open the built-in Settings app with

NSURL *url = [NSURL URLWithString:UIApplicationOpenSettingsURLString];
if ([[UIApplication sharedApplication] canOpenURL:url]) {
   [[UIApplication sharedApplication] openURL:url];
}

cross compiling

http://shift.net.nz/2010/09/compiling-freetype-for-iphoneios/

problem

file is universal but does not contain a(n) armv7 slice for architecture armv7 try to remove armv7s from the build settings

crash logs

~/Library/Logs/CrashReporter/MobileDevice/

ld: symbol(s) not found for architecture armv7

dit betekent dat er een sourcefile (.m / .mm of .cpp) niet gevonden kan worden of niet wordt mee-gecompiled. Ook al zit deze misschien wel in je projectree. Oplossing: ga naar je Project settings klik op de juiste Target en ga dan naar ''Compile sources''. Sleep de ontbrekende source file hier naar toe.
