在UIView中绘制垂直线

Question

UIView * lineView = [[UIView alloc] initWithFrame:CGRectMake(0, dialogContainer.bounds.size.height - buttonHeight - buttonSpacerHeight, dialogContainer.bounds.size.width, buttonSpacerHeight)];
lineView.backgroundColor = [UIColor colorWithRed:198.0/255.0 green:198.0/255.0 blue:198.0/255.0 alpha:1.0f];
[dialogContainer addSubview:lineView];

我已经使用此代码在UIView上绘制水平线.如何将垂直线添加到UIView？

Answer 1

UIView * lineView = [[UIView alloc] initWithFrame:CGRectMake(dialogContainer.bounds.size.width/2, 0, buttonSpacerHeight, dialogContainer.bounds.size.height)];
lineView.backgroundColor = [UIColor colorWithRed:198.0/255.0 green:198.0/255.0 blue:198.0/255.0 alpha:1.0f];
[dialogContainer addSubview:lineView];
