Objective C - 生成间隔为 X 分钟的时间对象数组？

Question

我想创建一个 24 小时制的时间对象数组，每个对象之间的间隔为 X 分钟；并且应该验证为 NSDate/NSTime 对象。

ie：生成的输出

00:00, 00:30, 01:00, 01:30, etc

我希望时间对象可以针对 NSDates 进行验证。

我在想我们有一系列 NSDates，但我不知道如何在不超过 24 小时的情况下使每一个与前一个相距 X 分钟。

非常感谢

编辑：第一次尝试

好的，根据下面的答案，我已经尝试过了

      NSDateComponents *components = [[NSCalendar currentCalendar] components:NSCalendarUnitDay | NSCalendarUnitMonth | NSCalendarUnitYear fromDate:[NSDate date]];
        components.timeZone = [NSTimeZone localTimeZone];
        components.hour =  11;
        components.minute = 0;
        components.second = 0;

        NSDate *date = [[NSCalendar currentCalendar] dateFromComponents:components];


        NSDateFormatter *timeFormatter = [NSDateFormatter vic_timeFormatter];
        [timeFormatter setTimeZone:[NSTimeZone localTimeZone]];

        for (int i=1; i<48; i++) {

            NSUInteger seconds = (1800 * i);
            NSDate *newDate= [NSDate dateWithTimeInterval:seconds sinceDate:date];
            NSLog(@"newDate = %@", newDate);
            NSString *formatted = [timeFormatter stringFromDate:newDate];
            NSLog(@"Formatted = %@", formatted);
        }

        timeFormatter=nil;

我选择了 48，因为 1800 在 24 小时制中出现了 48 次

除了在我的日志中，它总是在 10:30 左右结束

理想情况下，我希望它运行到晚上 11:30 或 12:00；无论时间从什么时候开始（在上述场景中，它从上午 11 点开始）

日志返回如下；

Answer 1

尝试使用 dateWithTimeInterval 方法。示例

NSDate *newDate= [NSDate dateWithTimeInterval:1800 sinceDate:yourDate];
