场景:我们有时候再scrollView上在覆盖一个collection/scrollView,那么他们的滚动事件就会冲突,百度很很久,然后自己查文档解决了,现在把解决方法公布如下:- (void)scrollWheel:(NSEvent *)event{// NSLog(@"x:\t%f",event.deltaX);// NSLog(@"y:\t%f",event.deltaY);// NSLog(@"z:\t%f",event.deltaZ);//// N

+(NSString *)getMacIOAddress{ kern_return_t kr; CFMutableDictionaryRef matchDict; io_iterator_t iterator; io_registry_entry_t entry; NSMutableString *macAddress; matchDict = IOServiceMatching("IOEthernetInterface"); .
