CGEventRef KeyHandler - Xcode - Mac - objective-c

Question

So I have an app that when you press the numbers on your keyboard on top, it normally types the symbols.
But with the app it types the numbers.
But if I run it in xcode, everything works fine, but when i open the app outside of xcode it doesn't work.
I have the newest update of mac os x and xcode.

Can anybody help me please?

Here's what I would do. There are many ways to calculate the modified character, this is one of them.
#import "AppDelegate.h"
#interface AppDelegate ()
#property (assign) CFMachPortRef myEventTap;
#property (assign) CFRunLoopSourceRef myRunLoopSource;
#end
#implementation AppDelegate
CGEventRef KeyHandler(CGEventTapProxy proxy, CGEventType type, CGEventRef event, void *refcon)
{
// don't modify keys on the numeric keypad
CGEventFlags flags = CGEventGetFlags(event);
if (flags & kCGEventFlagMaskNumericPad)
return event;
// get the typed character
UniCharCount actualStringLength;
UniChar chars[3];
CGEventKeyboardGetUnicodeString(event, 3, &actualStringLength, chars);
// uncomment this line to log the typed character, the modifier flags (Shift, Option, etc.) and the key code (number of the key on the keyboard)
NSLog(#"%C %llX %lld", chars[0], flags, CGEventGetIntegerValueField(event, kCGKeyboardEventKeycode));
if (actualStringLength == 1) {
// map the character from string1 to string2 and vice versa
NSString *string1 = #"&é\"'(§è!çà";
NSString *string2 = #"1234567890";
NSString *typedString = [NSString stringWithCharacters:chars length:1];
// find the index of the typed character in string1
NSRange range = [string1 rangeOfString:typedString];
if (range.location != NSNotFound)
// get the character in string2 at the same index
chars[0] = [string2 characterAtIndex:range.location];
else {
// find the index of the typed character in string2
range = [string2 rangeOfString:typedString];
if (range.location != NSNotFound)
// get the character in string1 at the same index
chars[0] = [string1 characterAtIndex:range.location];
}
// if the character was found, replace the character in the event
if (range.location != NSNotFound)
CGEventKeyboardSetUnicodeString(event, 1, chars);
}
return event;
}
- (void)applicationDidFinishLaunching:(NSNotification *)aNotification {
// create an event tap, we want the key down and key up events
CGEventMask eventMask = CGEventMaskBit(kCGEventKeyDown) | CGEventMaskBit(kCGEventKeyUp);
self.myEventTap = CGEventTapCreate(kCGSessionEventTap, kCGHeadInsertEventTap, kCGEventTapOptionDefault, eventMask, KeyHandler, NULL);
if (self.myEventTap) {
// create a runloop source
self.myRunLoopSource = CFMachPortCreateRunLoopSource(kCFAllocatorDefault, self.myEventTap, 0);
// add it to the current run loop
CFRunLoopAddSource(CFRunLoopGetCurrent(), self.myRunLoopSource, kCFRunLoopCommonModes);
