IOS中本地建立和存儲Plist文件

 

1.建立plist文件

-(void)creatPlist{

    //1.建立plist文件的路徑(plist文件要存儲的本地路徑)
    NSString *filePath = [NSHomeDirectory() stringByAppendingString:@"/Documents/myPlist.plist"];
   
    NSLog(@"本地路徑是：%@",filePath);
   
    //2.準備存儲的數據
    NSMutableDictionary *dic = [NSMutableDictionary dictionary];
   
    [dic setValue:@"value1" forKey:@"key1"]; //value爲字符串
   
    [dic setValue:@[@"str1",@"str2",@"str3"] forKey:@"key2"]; //value爲數組
   
    [dic setValue:@{@"k1":@"v1",@"k2":@"v2"} forKey:@"key3"]; //value爲字典
   
    //3.將準備好的數據存儲到plist文件中
    [dic writeToFile:filePath atomically:YES];

    

    //**對數據進行修改
    [dic setObject:@"劉志平" forKey:@"key1"];
    [dic writeToFile:filePath atomically:YES]; //覆蓋修改前的數據

}

 

 

2.讀取plist文件

 

-(void)readPlist{
   
    //第一種狀況：讀取本地存儲的plist文件
    NSString *filePath = [NSHomeDirectory() stringByAppendingString:@"/Documents/myPlist.plist"]; //要讀取的plist文件的本地路徑

    NSDictionary *dic1 = [NSDictionary dictionaryWithContentsOfFile:filePath];
   
    NSLog(@"dic1 = %@",dic1);


    //第二種狀況：讀取工程內的plist文件
    NSString *path = [[NSBundle mainBundle]pathForResource:@"Info" ofType:@"plist"];
   
    NSDictionary *dic2 = [NSDictionary dictionaryWithContentsOfFile:path];
   
    NSLog(@"dic2 = %@",dic2);

 

}
