这是我的代码，

    NSString *dateString = @"2011-08-25 18:30:00 +0000";
NSDateFormatter *dateFormatter = [[NSDateFormatter alloc] init];
[dateFormatter setDateFormat:@"MM/dd/yyyy"];
NSDate *dateFromString = [[NSDate alloc] init];
dateFromString = [dateFormatter dateFromString:dateString];
NSLog(@"Converted date is %@",dateFromString);

输出是，

         Converted date is (null)

推荐答案

NSString *dateWithInitialFormat = @"2011-08-25 18:30:00 +0000";

NSDateFormatter *dateFormatter = [[NSDateFormatter alloc] init];
[dateFormatter setDateFormat:@"yyyy-MM-dd HH:mm:ss Z"];
NSDate *date = [dateFormatter dateFromString:dateWithInitialFormat];

[dateFormatter setDateFormat:@"MM/dd/yyyy"];
NSString *dateWithNewFormat = [dateFormatter stringFromDate:date];
NSLog(@"dateWithNewFormat: %@", dateWithNewFormat);

来自 NSLog:dateWithNewFormat:08/25/2011

From NSLog: dateWithNewFormat: 08/25/2011
