NSDateFormatter *formatOld = [[NSDateFormatter alloc] init];
[formatOld setDateFormat:@"dd MMM yyyy hh:mma"]; //3 Dec 2012 1:00PM
NSString *oldDate = @"3 Dec 2012 1:00PM";
NSDate *date = [formatOld dateFromString:oldDate];
NSDateFormatter *newFormate = [[NSDateFormatter alloc]init];
[newFormate setDateFormat:@"dd MMM yyyy 'and' hh:mm a"]; //3 Dec 2012" and "1:00PM
NSString *newdate =[newFormate stringFromDate:date];
NSLog(@"%@",newdate);
输出
