創建了plist表，寫入plist表中的數據不是一個student對象，我們要看的時候，需要以一個student對象去看。。。需要從plist表中恢復student對象的信息。我們只需要添加以下代碼：    

BOOL isDirectory; //判斷AppHome/Documents/student.plist文件是否存在（txt純文本）  
   if ([fileManager fileExistsAtPath:studentFilePath isDirectory:&isDirectory] && !isDirectory) {  
         
       NSLog(@"存在 student.plist !!");  
         
/        通過plist表生成數組對象  
       NSArray *studentList = [NSArray arrayWithContentsOfFile:studentFilePath];  
        //取出數組中對應字段的數組  
       NSArray *studentName = [studentList objectAtIndex:0];  
       NSArray *studentID = [studentList objectAtIndex:1];  
       NSArray *studentSex = [studentList objectAtIndex:2];  
       NSArray *studentImagePath = [studentList objectAtIndex:3];  
         
        //通過遍歷每個字段數組，恢復student對象  
       NSMutableArray *studentArray = [[NSMutableArray alloc] init];  
       for (int i = 0; i < [studentName count]; i++) {  
           Students *student = [[Students alloc] initWithName:[studentName objectAtIndex:i] ID:[[studentID objectAtIndex:i] intValue] Sex:[studentSex objectAtIndex:i] Photo:[studentImagePath objectAtIndex:i]];  
           [studentArray addObject:student];  
       }  
       NSLog(@"stuents:%s",[[studentArray description] UTF8String]);  
         
         
   }else{
