在iphone中以24小时格式检索小时 [英] Retrieving hours in 24 hour format in iphone

问题描述

我正在使用这种格式来获取小时

I am using this format to get hours

   NSDateFormatter *dateFormatter = [[NSDateFormatter alloc] init];
    dateFormatter.dateFormat = @"hh";
    [dateFormatter setTimeZone:[NSTimeZone systemTimeZone]];

    NSString *date = [dateFormatter stringFromDate:now];

    NSInteger myHour = [date intValue];

问题是它返回，例如 4Pm i希望它返回 16 而不是4.我该怎么做？我尝试用单一h替换hh无效。

The problem is it returns e.g 4Pm i Want it to return 16 Instead of 4. How can I do that? I tried replacing hh by single h by of no avail.

推荐答案

这里您的输入：

NSDateFormatter *dateFormatter = [[NSDateFormatter alloc] init];
[dateFormatter setDateFormat:@"hh"];
NSDate *Yourcurrenttime = [dateFormatter dateFromString:Yourstring];

并将日期转换为String ..

And date converted to the String ..

[dateFormatter setDateFormat:@"HH"];
NSString *date = [dateFormatter stringFromDate:now];

NSInteger myHour = [date intValue];
