ios5 和ios6 时间timeIntervalSinceDate的问题

在ios6中 timeIntervalSinceDate 的处理与ios5中是不一样的

NSString*origDate =@"2012-11-29 19:43:30";

NSDateFormatter*df =[[NSDateFormatter alloc] init];[df setFormatterBehavior:NSDateFormatterBehavior10_4];

[df setDateFormat:@"YYYY-MM-dd HH:mm:ss"];

NSDate*convertedDate =[df dateFromString:origDate];

[df release];

NSDate* sourceDate =[NSDate date];

NSLog(@"sourceDate: %@", sourceDate);

NSLog(@"convertedDate: %@", convertedDate);

NSTimeInterval ti =[ sourceDate timeIntervalSinceDate:convertedDate];

NSLog(@"interval double: %f", ti);

In iOS 5

interval double:711.113610

in iOS 6

interval double:31623151.242078  解决方法  将日期转换中的YYYY换成  yyyy就好了   timeIntervalSinceNow 的处理也一样
