对plist文件的简单封装

常常会用到对plist文件的封装

+(NSArray *)LoadFriendsDataFromPlist:(NSString *)plistName{

    NSString * filePath = [[NSBundle mainBundle]pathForResource:plistName ofType:@"plist"];

    NSArray * array = [NSArray arrayWithContentsOfFile:filePath];

    NSMutableArray * dataArray = [NSMutableArray array];

    

    for (NSDictionary * dic in array) {

        //读取分组名

        NSString * groupName = [dic objectForKey:@"groupName"];

        //读取好友

        NSArray * friendArray =[dic objectForKey:@"friends"];

        //封装好友为

        NSMutableArray * personArray = [NSMutableArray array];

        for (NSDictionary * dic in friendArray) {

            Person * person = [[Person alloc]initWithName:[dic objectForKey:@"name"] iconName:[dic objectForKey:@"icon"] introduction:[dic objectForKey:@"intro"]];

            [personArray addObject:person];

        }

        NSDictionary * groupDic = @{@"friends":personArray,@"groupName":groupName};

        [dataArray addObject:groupDic];

    }

    return dataArray;

}
