原标题:I want to slide a transparent menu in from the left

我想执行上面显示的菜单。 我是一个全新的iOS。 我从几天以来就一直在寻找这种控制。

谁能从零开始 一步一步地指导我?

最佳回答

您可通过以下步骤实施上述内容:

1 & gt; Left 菜单视图是 UIView 添加为子视图, 在子视图中添加了各种 cutom 界面按钮 。

2 & gt; 开始您必须设置框架, 以便只显示视图的某个特定部分( 部分) 。

3 & gt; 在单击指标按钮时, 将框架扩展到满, 以显示按钮 。

4 & gt; 在下个单击 i. e( odclicks) 时, 组合框架 。

以上动画可以用简单的 UIView 动画来实现。

样本代码(原件框架宽度=300,58,300):-

yourMenuView.frame=CGRectMake(0,10,100,300);

[yourViewController addSubview:yourMenuView];

-(IBAction)expandMenu:(id)sender
{
[UIView beginAnimations:nil context:nil];
[UIView setAnimationDuration:0.75];
[UIView setAnimationCurve:UIViewAnimationCurveEaseIn];
CGRect frame=yourMenuView.frame;
frame.size.width+=200;
yourMenuView.frame=frame;
[myview removeFromSuperview];
[UIView commitAnimations];
}

-(IBAction)collapseMenu:(id)sender
{
[UIView beginAnimations:nil context:nil];
[UIView setAnimationDuration:0.75];
[UIView setAnimationCurve:UIViewAnimationCurveEaseIn];
CGRect frame=yourMenuView.frame;
frame.size.width-=200;
yourMenuView.frame=frame;
[myview removeFromSuperview];
[UIView commitAnimations];

}
