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

╰半夏微凉° 2022-08-22 03:50 276阅读 0赞

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 = \[NSCalendar currentCalendar\];

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：
