如何在viewcontroller上添加滚动视图？

Question

我想将Scroll View添加到ViewController中。我已经通过代码创建了viewcontroller。

secondView = [[SecondView alloc] initWithNibName:@"second" bundle:nil];

现在我想在视图控制器上添加滚动视图。有可能吗？

Answer 1

[viewController.view addSubview：scrollView]

Answer 2

是的，可以将scrollview添加到viewcontroller。

按照这个，它可能会帮助你

CGRect rect=CGRectMake(0,0,320,480);

UIScrollView *scroll = [[UIScrollView alloc] initWithFrame:rect];

scroll.contentSize = CGSizeMake(320, 400);
scroll.showsHorizontalScrollIndicator = YES;
[self.secondview addSubview:scroll];

修改

SecondView *secondView = [[SecondView alloc] initWithNibName:@"SecondView" bundle:[NSBundle mainBundle]];   
    [self.navigationController pushViewController:secondView animated:YES]; 

    CGRect frame = CGRectMake(0,0,320,600);
    scroll = [[UIScrollView alloc] initWithFrame:frame];
    scroll.contentSize = CGSizeMake(secondView.bounds);
            scroll.showsHorizontalScrollIndicator = YES;
            scroll.showsVerticalScrollIndicator = YES;              
    [secondView.view addSubview:scroll];        
    [scroll release];

祝你好运..

将以下内容放在SecondView类的viewDidLoad中

-(void)viewDidLoad{

   [super viewDidLoad];
   CGRect frame = CGRectMake(0,0,320,600);
   UIScrollView *scroll = [[UIScrollView alloc] initWithFrame:frame];
   scroll.contentSize = CGSizeMake(secondView.bounds);
            scroll.showsHorizontalScrollIndicator = YES;
            scroll.showsVerticalScrollIndicator = YES;              
    [secondView.view addSubview:scroll];        
    [scroll release];
}
