前言在开发IOS中常常需要用到这一功能,在限定一个月的时间间隔为第一天和最后一天,需要知道这个月有多少天,才能知道最后一天是多少号,而且还要知道是否是闰年,可能2月只有28天。
话不多说,附上代码:- (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 - 获取某年某月的天数- (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;}
总结以上就是IOS获取指定年月的当月天数的全部内容,希望本文的内容对大家开发IOS能有所帮助。
