讀寫.plist檔案的例子

原文地址：http://hi.baidu.com/sushii/blog/item/51e0203e57964bfe55e723e9.html

想在一個類裡把個數組寫進.plist檔案裡，再在另一個類裡從這個.plist檔案把數組讀取出來？

以name，phoneNumber，age三個欄位，為例。我是做的iphone,在文字框中輸入資料，擷取後，裝入數組中。然後把數組寫入.plist檔案

寫操作

    NSString *name=[txt1 text];
    NSNumber *phoneNumber=[[NSNumber alloc] initWithInt:[[txt2 text] intValue]];
    NSNumber *age=[[NSNumber alloc] initWithInt:[[txt3 text] intValue]];
    
    NSMutableArray *array=[[NSMutableArray alloc]init];
    [array  addObject:name];
    [array  addObject:phoneNumber];
    [array  addObject:age];

    NSArray *paths=NSSearchPathForDirectoriesInDomains(NSDocumentDirectory,NSUserDomainMask,YES);
    NSString *path=[paths    objectAtIndex:0];
    NSString *filename=[path stringByAppendingPathComponent:@"personal.plist"];    
    
    [array writeToFile:filename  atomically:YES];
    [array release]; 

讀操作

NSArray *paths=NSSearchPathForDirectoriesInDomains(NSDocumentDirectory,NSUserDomainMask,YES);
    NSString *path=[paths    objectAtIndex:0];
    NSString *filename=[path stringByAppendingPathComponent:@"personal.plist"];
    
    NSMutableArray *array=[[NSMutableArray alloc] initWithContentsOfFile:filename];
    
    txt1.text=[array objectAtIndex:0];
    txt2.text=[[NSString alloc] initWithFormat:@"%d",[[array objectAtIndex:1] intValue]];
    txt3.text=[[NSString alloc] initWithFormat:@"%d",[[array objectAtIndex:2] intValue]];

    [array release];
