如何动态地将多个具有不同名称的标签添加到scrollview中

Question

以下是我的代码...为Quiz App生成许多标签以显示答案

for (NSInteger i = 0, y = 50; i < 3 ; i++, y += 30) {
    UILabel *nameLabel = [[UILabel alloc] initWithFrame:CGRectMake(10, 50, 100, 25)];
    _optoin1 =  [[NSString alloc] initWithUTF8String:(const char *) sqlite3_column_text(statement, 2)]; _op1.text= _optoin1;
    nameLabel.text =_optoin1;
    [_myscrollView addSubview:nameLabel];
    sqlite3_finalize(statement);
    key++;
}

Answer 1

key用于从db获取下一个columnvalue。它生成四个标签..

            for (NSInteger i = 0, y = 50; i < 4 ; i++, y += 30)
            {
                UILabel *nameLabel = [[UILabel alloc] initWithFrame:CGRectMake(10, y, 100, 25)];
                _optoin1 =  [[NSString alloc] initWithUTF8String:(const char *)              sqlite3_column_text(statement, key)];
                nameLabel.tag = labl_id;
                nameLabel.text =_optoin1;
                [_myscrollView addSubview:nameLabel];
                //sqlite3_finalize(statement);
                key++;
                labl_id++;
            }
