iOS開發中plist文件的創建與簡單讀取（一）

 

 

1. 創建一個工程

2. 新建一個plist文件(command+N快捷鍵或者新建文件 如圖下的紅色圈)

 

3. 紅色圈是plist的文件名，這裡默認為Property List，點擊創建就可以瞭

4 。plist文件如下所示

5 如圖所示類型為字典類型

6 兩個字典創建好瞭，註意這裡給字典裡添加數據時，要點擊teacher的三角符號朝下時，點擊“+”,這樣才創建在字典裡，不按照這樣做，會在字典外面。

7 添加數據

8 plistde的文件創建好瞭，創建一個新的文件

studentViewController

 

studentViewController.m

 

- (void)viewDidLoad
{
    [super viewDidLoad];
	// Do any additional setup after loading the view.
    
    NSString* plistfile1 = [[NSBundle mainBundle]pathForResource:@Property List ofType:@plist];
    NSMutableDictionary* data = [[NSMutableDictionary alloc]initWithContentsOfFile:plistfile1];
    //打印出字典裡的數據
    NSLog(@%@,data);
    [data setObject:@add some content forKey:@c_key];
    
    //獲取應用沙盒的Douch
    NSArray* paths = NSSearchPathForDirectoriesInDomains(NSDocumentationDirectory, NSUserDomainMask, YES);
    NSString* plist1 = [paths objectAtIndex:0];
    
    //獲取一個plist文件
    NSString* filename = [plist1 stringByAppendingString:@test.plist];
    [data writeToFile:filename atomically:YES];
    NSMutableDictionary* data1 = [[NSMutableDictionary alloc]initWithContentsOfFile:filename];
    //打印出字典裡的數據
    NSLog(@%@,data1);
    
    //修改一個plist文件的數據
    [data1 setObject:@要修改的數值 forKey:@要修改的name];
    [data1 writeToFile:filename atomically:YES];

    
    
}

輸出結果
