【代碼筆記】iOS-計算時間差，筆記ios-時間差

一，代碼。

- (void)viewDidLoad {    [super viewDidLoad];    // Do any additional setup after loading the view, typically from a nib.        //時間格式 2015-07-20 18:34:31    NSLog(@"%ld",[self getTimeInterval:@"2015-07-20 00:00:00"]);    }//計算時間差- (NSInteger)getTimeInterval:(NSString *)sendDateString{    NSInteger minute;    if (sendDateString ==nil||sendDateString.length==0) {        ;    }    else    {         NSDateFormatter *dateFormatter = [[NSDateFormatter alloc] init];        [dateFormatter setDateFormat:@"yyyy-MM-dd HH:mm:ss"];        //現在時間        NSDate * currentdate = [NSDate date];        NSDate * currentDate = [dateFormatter dateFromString:[dateFormatter stringFromDate: currentdate]];        NSLog(@"---currentdate--%@",currentDate);        //結束時間        NSDate * endDate = [dateFormatter dateFromString:sendDateString];        NSLog(@"---endDate--%@",endDate);        //得到時間差        NSTimeInterval time = [currentDate timeIntervalSinceDate:endDate];        NSLog(@"---time---%ld",(long)time);        NSLog(@"--minitus--%ld",(long)time);        NSLog(@"---days--%d",((int)time)/(3600*24));        NSLog(@"---hours--%d",((int)time)%(3600*24)/3600);           }    return minute;}

 

二，輸出。
