一，代碼。

- (void)viewDidLoad{    [super viewDidLoad];    // Do any additional setup after loading the view.        NSLog(@"-------getCurrentTime---%@",[self getCurrentTime]);    }#pragma -mark -擷取現在的日曆時間  輸出形式 2014-06-27 15:41:55- (NSString *) getCurrentTime{        NSDate* date = [NSDate date];        //日曆為陽曆     NSCalendar *calendar = [[NSCalendar alloc]initWithCalendarIdentifier:NSGregorianCalendar];    //表示一個日期對象的組件    NSDateComponents *component = [calendar components:NSCalendarUnitYear | NSCalendarUnitMonth | NSCalendarUnitDay | NSCalendarUnitHour | NSCalendarUnitMinute | NSCalendarUnitSecond fromDate:date];    //設定時區    [component setTimeZone:[NSTimeZone systemTimeZone]];        NSInteger year = [component year];    NSInteger month = [component month];    NSInteger day = [component day];    NSInteger hour = [component hour];    NSInteger minute = [component minute];    NSInteger second = [component second];        NSString* dateString = [NSString stringWithFormat:@"%i-%@%i-%@%i %@%2i:%@%2i:%@%i" , year , month > 10 ? @"" :@"0",month , day > 10 ? @"" :@"0", day , hour > 10 ? @"" :@"0", hour  , minute > 10 ? @"" :@"0", minute ,second > 10 ? @"" :@"0", second];    return dateString;    }
