NSString *filePath = [[NSBundle mainBundle] pathForResource:@"文件的名字" ofType:@"json"];
//获取文件内容
NSString *jsonStr  = [NSString stringWithContentsOfFile:filePath encoding:NSUTF8StringEncoding error:nil];
//将文件内容转成数据

NSArray *provinceSchoolArray = [NSJSONSerialization JSONObjectWithData:jaonData options:NSJSONReadingMutableContainers error:nil];
