自动调整 UIScrollView 大小

发布于 2024-09-06 06:25:07 字数 1337 浏览 3 评论 0原文

我制作了一个 UIViewController，它以编程方式生成 UIScrollView。一切都很好，但是当我旋转设备时，UIScollView 应该调整大小，以便它占据我的视图的完整宽度。

有没有办法在不重建完整 UIScrollView 的情况下做到这一点？

非常感谢！ Sebastian

这是在我的 viewDidLoad 中调用的：

    -(void)buildmyScroller {
    myScroller = [[UIScrollView alloc] initWithFrame:CGRectMake(0, 800, 768, 100)];


    //...adding some subviews to myScroller


    thumbScroller.contentSize = CGSizeMake(3000, 100);
    [[self view] addSubview:myScroller];
}

然后我尝试用它调整 myScroller 的大小，当我使用 setFrame 时，我说 myScroller 不会响应它...：

-(void)changemyScroller {
        UIInterfaceOrientation interfaceOrientation = self.interfaceOrientation;
    if (interfaceOrientation == UIInterfaceOrientationPortrait) {
        [thumbScroller setFrame:CGRectMake(0, 805, 768, 150)];
    }
    else if (interfaceOrientation == UIInterfaceOrientationPortraitUpsideDown){
        thumbScroller.frame = CGRectMake(0, 805, 768, 150);
    }
    else if (interfaceOrientation == UIInterfaceOrientationLandscapeLeft){
        thumbScroller.frame = CGRectMake(0, 549, 1024, 150);
    }
    else if (interfaceOrientation == UIInterfaceOrientationLandscapeRight){
        thumbScroller.frame = CGRectMake(0, 549, 1024, 150);
    }
}

并在 didAnimateFirstHalf 中调用该方法...因为我不确定在哪里否则就可以调用它。

再次非常感谢！

I made a UIViewController, which programatically generates a UIScrollView. Everything's fine, but when I rotate the Device, the UIScollView should resize so it takes the complete width of my View.

Is there a way to do that without rebuilding the complete UIScrollView ?

Thx a lot !

This is called in my viewDidLoad:

    -(void)buildmyScroller {
    myScroller = [[UIScrollView alloc] initWithFrame:CGRectMake(0, 800, 768, 100)];


    //...adding some subviews to myScroller


    thumbScroller.contentSize = CGSizeMake(3000, 100);
    [[self view] addSubview:myScroller];
}

Then I tried to resize myScroller with this, when I used setFrame, I said myScroller would not respond to it... :

-(void)changemyScroller {
        UIInterfaceOrientation interfaceOrientation = self.interfaceOrientation;
    if (interfaceOrientation == UIInterfaceOrientationPortrait) {
        [thumbScroller setFrame:CGRectMake(0, 805, 768, 150)];
    }
    else if (interfaceOrientation == UIInterfaceOrientationPortraitUpsideDown){
        thumbScroller.frame = CGRectMake(0, 805, 768, 150);
    }
    else if (interfaceOrientation == UIInterfaceOrientationLandscapeLeft){
        thumbScroller.frame = CGRectMake(0, 549, 1024, 150);
    }
    else if (interfaceOrientation == UIInterfaceOrientationLandscapeRight){
        thumbScroller.frame = CGRectMake(0, 549, 1024, 150);
    }
}

And called the method in didAnimateFirstHalf... cause I'm not shure where else to call it.

Thx a lot again !!

[scrollView setFrame:CGRectmake(x, y, 宽度, 高度)];
//也许您需要对scrollView的内容执行相同的操作以使其适合您的布局

应该这样做。如果需要过渡，您可以将其包装在 UIAnimation 块中。

试试这个：

    if(self.rowNumber == 0){
    /******************* Scroller Setup *****************/
    // how many pages
    int pageCount = 5;
    //set up the scrollView
    UIScrollView *scroller = [[UIScrollView alloc] initWithFrame:CGRectMake(0, 0, 768, 960)];
    // support for Landscape Orienation
    if(UIInterfaceOrientationLandscapeLeft){
        [scroller  setFrame:CGRectMake(0,0,1024, 704)];
    }
    if(UIInterfaceOrientationLandscapeRight){
        [scroller  setFrame:CGRectMake(0,0,1024, 704)];
    }

Try this:

    if(self.rowNumber == 0){
    /******************* Scroller Setup *****************/
    // how many pages
    int pageCount = 5;
    //set up the scrollView
    UIScrollView *scroller = [[UIScrollView alloc] initWithFrame:CGRectMake(0, 0, 768, 960)];
    // support for Landscape Orienation
    if(UIInterfaceOrientationLandscapeLeft){
        [scroller  setFrame:CGRectMake(0,0,1024, 704)];
    }
    if(UIInterfaceOrientationLandscapeRight){
        [scroller  setFrame:CGRectMake(0,0,1024, 704)];
    }
