前言

在開發IOS中常常需要用到這一功能,在限定一個月的時間間隔為第一天和最後一天,需要知道這個月有多少天,才能知道最後一天是多少號,而且還要知道是否是閏年,可能2月只有28天。

話不多說,附上代碼:

- (void)viewDidLoad {  [super viewDidLoad];  // Do any additional setup after loading the view, typically from a nib.  NSLog(@"%ld",(long)[self howManyDaysInThisYear:2016 withMonth:1]);  NSLog(@"%ld",(long)[self howManyDaysInThisYear:2016 withMonth:2]);  NSLog(@"%ld",(long)[self howManyDaysInThisYear:2016 withMonth:3]);  NSLog(@"%ld",(long)[self howManyDaysInThisYear:2016 withMonth:4]);  NSLog(@"%ld",(long)[self howManyDaysInThisYear:2016 withMonth:5]);  NSLog(@"%ld",(long)[self howManyDaysInThisYear:2016 withMonth:6]);  NSLog(@"%ld",(long)[self howManyDaysInThisYear:2016 withMonth:7]);  NSLog(@"%ld",(long)[self howManyDaysInThisYear:2016 withMonth:8]);}#pragma mark - 擷取某年某月的天數- (NSInteger)howManyDaysInThisYear:(NSInteger)year withMonth:(NSInteger)month{  if((month == 1) || (month == 3) || (month == 5) || (month == 7) || (month == 8) || (month == 10) || (month == 12))    return 31 ;   if((month == 4) || (month == 6) || (month == 9) || (month == 11))    return 30;   if((year % 4 == 1) || (year % 4 == 2) || (year % 4 == 3))  {    return 28;  }   if(year % 400 == 0)    return 29;   if(year % 100 == 0)    return 28;   return 29;}

總結
