從NSString轉換為NSDate

Question

我正在嘗試將Nsstring對象轉換為Nsdate。我的代碼是這樣的

     NSString *Time=@"09/26/2011 2:06 AM";
     NSDateFormatter *dateFormatter = [[NSDateFormatter alloc] init];
        //[NSDateFormatter setDefaultFormatterBehavior:NSDateFormatterBehaviorDefault];
        //Time=[mystr substringToIndex:3];
        [dateFormatter setDateFormat:@"MM-DD-YYYY HH:MM"];
        NSDate *dateFrom = [dateFormatter dateFromString:Time];
        NSLog(@"\n\n\n\nThe date==%@\n\n\n\n\n",dateFrom);

但它返回一個空值。。任何幫助表示贊賞。在此先感謝

嘗試更換：

[dateFormatter setDateFormat:@"MM-DD-YYYY HH:MM"];

與

[dateFormatter setDateFormat:@"MM/dd/yyyy HH:mm a"];
