objective-c - CFNumberRef を NSInteger に変換する

Question

#import "someClass.h"

@implementation someClass

- (NSInteger *)checkWakeOnLan {
    SCDynamicStoreRef ds = SCDynamicStoreCreate(kCFAllocatorDefault, CFSTR("myapp"), NULL, NULL);
    CFDictionaryRef dr = SCDynamicStoreCopyValue(ds, CFSTR("State:/IOKit/PowerManagement/CurrentSettings"));
    CFNumberRef wol=CFDictionaryGetValue(dr, CFSTR("Wake On LAN"));
    CFRelease(dr);
    CFRelease(ds);

ここで私の問題、CFNumberRefをNSIntegerに変換する方法、私は何度も何度も試しましたが、いつでも「キャストなしでポインターから整数を作成します」

    NSInteger *value = [... ?];
    return value;
}

- (IBAction)doStuff:(NSButton *)sender {
    [myBevelButton setState:[self checkWakeOnLan]]; //setState takes NSInteger
    //myBevelButton defined elsewhere, shows different icons 
}
