IOS---如何获取当前的日期和时间（阴历阳历），并显示带阴历阳历24节气的日历
创建两个UILable: Lable1,Lable2.创建好IBOutlate并连线， 然后用如下方法：
-(void)updateLabel {
NSDate* now = [NSDate date];
NSCalendar *cal = [NSCalendar currentCalendar];
unsigned int unitFlags = NSYearCalendarUnit | NSMonthCalendarUnit | NSDayCalendarUnit |NSHourCalendarUnit | NSMinuteCalendarUnit |NSSecondCalendarUnit;
NSDateComponents *dd = [cal components:unitFlags fromDate:now];
int y = [dd year];
int m = [dd month];
int d = [dd day];
int hour = [dd hour];
int min = [dd minute];
int sec = [dd second];
Lable1.text = [NSString stringWithFormat:@"2d%:2d%:2d%",y,m,d];
Lable2.text =[NSStrinstringWithFormat:@"2d%:2d%:2d%",hour,min,sec];
}
- (void)onTimer {
[viewController updateLabel];
}
在AppDeletate.m文件中增加如下方法：
- (void)applicationDidFinishLaunching:(UIApplication *)application {
timer = [NSTimer scheduledTimerWithTimeInterval:(1.0) target:selfselector:@selector(onTimer) userInfo:nil repeats:YES];
[window addSubview:viewController.view];
[window makeKeyAndVisible];
}
运行就大功告成了，看效果：

#define ChineseFestival @[@"除夕",@"春节",@"中秋",@"五一",@"国庆",@"儿童",@"圣诞",@"七夕",@"端午"]
