如何从NSString timeStyle获取NSDate格式化语言环境设置

Question

如何从根据区域设置格式化的NSString获取NSDate（时间）？让我解释。根据设备的区域设置，我必须将HS中的myString转换为NSDate：ss（意大利格式）

NSLocale *locale = [NSLocale autoupdatingCurrentLocale];
 dateFormatter = [[NSDateFormatter alloc] init];
 [dateFormatter setTimeStyle: NSDateFormatterShortStyle];
 [dateFormatter setDateStyle: NSDateFormatterFullStyle];
 [dateFormatter setLocale: [[NSLocale alloc] initWithLocaleIdentifier: [locale objectForKey: NSLocaleIdentifier]]];

我的NSString可以是：@“2014-01-01 6:15 PM”或@“2014-01-01 18:15”或@“2014-01-01 6:15 MUU”或???? 我的结果必须是：@“01/01/2014 18:15”

[dateFormatter setDateFormat:@"????"];
NSDate *myDate = [dateFormatter dateFromString:myNSString];

如何获取区域格式以正确设置格式化程序？

Answer 1

你好，你必须写下这样的东西：

NSDateFormatter *dateFormatter = [[NSDateFormatter alloc] init];
dateFormatter.dateFormat = @"yyyy-MM-dd HH:mm";
[dateFormatter setTimeZone:[NSTimeZone timeZoneWithName:@"Europe/Italy"]];//include you're location from what country time you want
NSString *dateString = [dateFormatter stringFromDate:[NSDate date]];
NSLog(@"New NSDate (NSDate): %@", [dateFormatter stringFromDate:date]);

Answer 2

NSString* stringDate  = @"January 1, 2000 at 9:10 PM";    
NSDateFormatter *dateFormatter = [[NSDateFormatter alloc] init];
[dateFormatter setDateStyle:NSDateFormatterLongStyle];
[dateFormatter setTimeStyle:NSDateFormatterShortStyle]; 

NSDate *tempDate      = [dateFormatter dateFromString:stringDate];
[dateFormatter setDateFormat:@"HH:mm"];

stringDate = [dateFormatter stringFromDate:tempDate];
