1.加载JSON文件

a.JSON文件的路径

 NSString *path = [[NSBundle mainBundle] pathForResource:@"XXXX.json" ofType:nil];

b.加载JSON文件  获取Data数据 

 NSData *data = http://www.mamicode.com/[NSData dataWithContentsOfFile:path];

c.将JSON数据转为NSArray或者NSDictionary

NSArray *dictArray = [NSJSONSerialization JSONObjectWithData:data options:NSJSONReadingMutableContainers error:nil];

d.将字典转成模型

 NSMutableArray *array= [NSMutableArray array];
        for (NSDictionary *dict in dictArray) {
            XX自己的模型 *p = [XX自己的模型 xxWithDict:dict];
            [array addObject:p];
        }
       return array;
2.加载Plist文件

a.获得plist的全路径
        NSString *path = [[NSBundle mainBundle] pathForResource:@"XXX.plist" ofType:nil];
        
       b.加载数组
        NSArray *dictArray = [NSArray arrayWithContentsOfFile:path];
        
        c.将dictArray里面的所有字典转成模型对象,放到新的数组中
        NSMutableArray *gameArray = [NSMutableArray array];
        for (NSDictionary *dict in dictArray) {
            // 3.1.创建模型对象
            QsGame *game = [QsGame gameWithDict:dict];
            // 3.2.添加模型对象到数组中
            [gameArray addObject:game];
        }
        // 4.赋值
        _games = gameArray;
3.读取沙河中的plist

   NSString *home = NSHomeDirectory(); // 获得沙盒根路径
     NSString *docPath = [home stringByAppendingPathComponent:@"Documents"]; // 拼接document路径
     NSString *filepath = [docPath stringByAppendingPathComponent:@"data.plist"]; //  获得文件路径
     NSArray *data = http://www.mamicode.com/[NSArray arrayWithContentsOfFile:filepath]; // >     NSLog(@"%@", data);
