对plist文件进行简单的封装

+ (NSArray *)loadDataFromPlistWithName:(NSString *)plistName{
    NSString *path = [[NSBundle mainBundle] pathForResource:plistName ofType:@"plist"];
    NSArray *array = [NSArray arrayWithContentsOfFile:path];
    
    NSMutableArray *dataArray = [NSMutableArray array];
    
    for (int i = 0; i < array.count; i++) {
        NSDictionary *dic = [array objectAtIndex:i];
        //读取分组名
        NSString *groupName = [dic objectForKey:@"groupName"];
        //读取这一组的好友
        NSArray *friendsArray = [dic objectForKey:@"friends"];
        //封装每一个好友为PersonModel类型
        NSMutableArray *personArray = [NSMutableArray array];
        
        for (NSDictionary *personDic in friendsArray) {
            PersonModel *person = [[PersonModel alloc] initWithName:[personDic objectForKey:@"name"] iconName:[personDic objectForKey:@"icon"] introduction:[personDic objectForKey:@"intro"]];
