所以我有一个应用程序，当你按下键盘顶部的数字时，它通常会输入符号。但是使用该应用程序，它会键入数字。

但是如果我在 xcode 中运行它，一切正常，但是当我在 xcode 之外打开应用程序时，它就不起作用了。

我有 mac os x 和 xcode 的最新更新。

有人可以帮我吗？

这就是我要做的。计算修改字符的方法有很多种，这是其中一种。

#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);
}
