CGEventRef KeyHandler - Xcode - Mac

Question

У меня есть приложение, которое, когда вы нажимаете цифры на клавиатуре сверху, обычно вводит символы. Но с приложением он вводит числа.

Но если я запустил его в xcode, все будет хорошо, но когда я открою приложение за пределами xcode, он не сработает.

У меня есть новейшее обновление mac os x и xcode.

Может кто-нибудь помочь мне, пожалуйста?

Вот что я буду делать. Существует много способов вычисления модифицированного символа, это один из них.

#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); 
    } 
} 

- (void)applicationWillTerminate:(NSNotification *)aNotification { 
    // remove the event tap 
    if (self.myRunLoopSource) { 
     CFRunLoopSourceInvalidate(self.myRunLoopSource); 
     CFRelease(self.myRunLoopSource); 
    } 
    if (self.myEventTap) 
     CFRelease(self.myEventTap); 
}
