iOS 6 dateFromString返回错误的日期
问题描述:
我最近升级到iOS 6,并注意到dateFromString不能正常工作,除非我用我的dateFormat做错了什么。它在升级之前正在工作。iOS 6 dateFromString返回错误的日期
代码:
NSString *string = @"2012-09-24 - Sun";
NSLog(@"string = %@", string);
NSDateFormatter *df = [[NSDateFormatter alloc] init];
NSLocale *locale = [[NSLocale alloc] initWithLocaleIdentifier:@"en-US"];
[df setLocale:locale];
[df setDateFormat:@"yyyy-MM-dd - EEE"];
NSDate *date = [df dateFromString:string];
NSLog(@"date = %@", date);
输出:
string = 2012-09-24 - Sun
date = 1999-12-26 05:00:00 +0000
有什么建议?

请检查:
NSString *string = @"2012-09-24 - Sun";
NSLog(@"string = %@", string);
NSDateFormatter *df = [[NSDateFormatter alloc]init];
[df setDateFormat:@"yyyy-MM-dd - EEE"];
NSDate * date = [df dateFromString: string];
NSDate * sourceDate = date;
NSTimeZone* sourceTimeZone = [NSTimeZone timeZoneWithAbbreviation:@"GMT"];
NSTimeZone* destinationTimeZone = [NSTimeZone systemTimeZone];
NSInteger sourceGMTOffset = [sourceTimeZone secondsFromGMTForDate:sourceDate];
NSInteger destinationGMTOffset = [destinationTimeZone secondsFromGMTForDate:sourceDate];
NSTimeInterval interval = destinationGMTOffset - sourceGMTOffset;
date = [[NSDate alloc] initWithTimeInterval:interval sinceDate:date];
NSLog(@"date = %@", date);
+0
什么是sourceDate? –
