get AM / PM from users set time on iOS

提问by Neil

I am wondering if there is a way that you can get am/pm from the users set time on iOS.

我想知道是否有一种方法可以从用户在 iOS 上设置的时间获取 am/pm。

I am currently using this method to get time:

我目前正在使用这种方法来获取时间:

NSDateFormatter *formatter = [[NSDateFormatter alloc] init];
[formatter setDateFormat:@"HH"];
hours.text = [formatter stringFromDate:[NSDate date]];

[formatter setDateFormat:@"m"];
minutes.text = [formatter stringFromDate:[NSDate date]];
if ([minutes.text intValue] < 10) {
    minutes.text = [NSString stringWithFormat:@"0%@",[formatter stringFromDate:[NSDate date]]];
}
[formatter release];

I know I am using HH to get the hours and for the 12 hour format I have to use "hh" bu this does not solve the problem, I need to retrieve the AM/PM.

我知道我使用 HH 来获取小时数,对于 12 小时格式,我必须使用“hh”,但这并不能解决问题,我需要检索 AM/PM。

Hopefully someone can help!

希望有人能帮忙!

Here you go. This is the date with am/pm formatting.

干得好。这是带有 am/pm 格式的日期。

NSDateFormatter *formatter = [[NSDateFormatter alloc] init];
[formatter setDateFormat:@"hh:mm:ss a"];
NSLog(@"Today's Date and Time: %@", [formatter stringFromDate:[NSDate date]]);
[formatter release];

Swift 最简单的答案:
