How to embed UITableView into UIScrollView?
I made an UIScrollView with paging enabled (horizontal scrolling), and I want to embed several U开发者_开发知识库ITableView objects into the UIScrollView.
How to do that ? Is there any sample code ?
Thanks.
Below you will find the example that loads two UITableViewControllers as separate pages.
// .h File
@interface PagingViewController : UIViewController <UIScrollViewDelegate>{
}
-(void)loadPage:(int)page;
@end
// .m File
static NSUInteger kNumberOfPages = 2;
@interface PagingViewController ()
@property(nonatomic,retain)NSMutableArray *viewControllers;
@property(nonatomic,retain)UIView *contentView;
@end
@implementation PagingViewController
@synthesize viewControllers;
@synthesize contentView;
-(id)init{
self = [super init];
if(self) {
NSMutableArray *controllers = [[NSMutableArray alloc] init];
for (unsigned i = 0; i < kNumberOfPages; i++)
{
[controllers addObject:[NSNull null]];
}
self.viewControllers = controllers;
[controllers release];
contentView = [[UIView alloc] initWithFrame:CGRectMake(0, 0, 320, 480)];
self.view = contentView;
[self loadPage:0];
}
return self;
}
- (void)loadPage:(int)page{
if (page < 0)
return;
if (page >= kNumberOfPages)
return;
if(page == 0){
FirstUITableViewController *firstTableVC = [viewControllers objectAtIndex:page];
if ((NSNull *)firstTableVC == [NSNull null]){
firstTableVC = [[FirstUITableViewController alloc] init];
[viewControllers replaceObjectAtIndex:page withObject:firstTableVC];
[firstTableVC release];
}
if (firstTableVC.view.superview == nil)
{
[contentView addSubview:firstTableVC.view];
}
}else if(page == 1){
SecondUITableViewController *secondTableVC = [viewControllers objectAtIndex:page];
if ((NSNull *)secondTableVC == [NSNull null]){
secondTableVC = [[SecondUITableViewController alloc] init];
[viewControllers replaceObjectAtIndex:page withObject:secondTableVC];
[secondTableVC release];
}
if (secondTableVC.view.superview == nil)
{
[contentView addSubview:secondTableVC.view];
}
}
}
// Don't forget to dealloc
Edit:
You can have a lot of objects in your tableView
, and self.tableView.scrollEnabled = YES
will give a vertical scroll view to that.
To get a horizontal scroll I would suggest that you create a tableView for each view controller and add a UIPageControl
with each page denoting a tableView
.
Check the UIPageControl Documentation.
