how can i make a uitableview container to bounce within the view - objective-c

Question

ok, so this is pretty simple one, but i hope i could explain this clearly - i have a table view that i would like to inset into a container, and then have the table bounces when it reaches the top / bottom. So far, I was able to put my table in a container, but the container is fixed on the view, while the table inside the container bounces. Again, I am looking for a way to fix the table to the container, while having the container bouncing.
Here is what I was able to do, following the code:
What I want to accomplish is to have the black box bouncing rather than the table within it.
my ViewDidLoad in the view controller .m:
- (void)viewDidLoad
{
[super viewDidLoad];
// Do any additional setup after loading the view, typically from a nib.
//General View Setup
UIColor *background = [[UIColor alloc] initWithPatternImage:[UIImage imageNamed:#"backgroundimage.png"]];
self.view.backgroundColor = background;
//Table View Data
listOfItems = [[NSMutableArray alloc] init];
NSArray *appleComputers = [NSArray arrayWithObjects:#"iPhone",#"iPod",#"MacBook",#"MacBook Pro",nil];
NSDictionary *appleComputersDict = [NSDictionary dictionaryWithObject:appleComputers forKey:#"Computers"];
NSArray *otherComputers = [NSArray arrayWithObjects:#"HP", #"Dell", #"Windows", #"Sony", #"Ivory", #"IBM", nil];
NSDictionary *otherComputersDict = [NSDictionary dictionaryWithObject:otherComputers forKey:#"Computers"];
[listOfItems addObject:appleComputersDict];
[listOfItems addObject:otherComputersDict];
self.navigationItem.title = #"Computers";
// Create a table
tblSimpleTable.delegate = self;
CGRect cgRct = CGRectMake(10, 50, 300, 300);
tblSimpleTable = [[UITableView alloc] initWithFrame:cgRct style:UITableViewStyleGrouped]; // Initilize the table
[tblSimpleTable setBackgroundColor:[UIColor blackColor]];
tblSimpleTable.sectionHeaderHeight = 30.0;
tblSimpleTable.sectionFooterHeight = 30.0;
tblSimpleTable.delegate = self;
tblSimpleTable.dataSource = self;
[self.view addSubview:tblSimpleTable];
//Create the header
UIView *containerView = [[UIView alloc] initWithFrame:CGRectMake(0, 0, 300, 60)];
UILabel *headerLabel = [[UILabel alloc] initWithFrame:CGRectMake(10, 20, 300, 40)];
headerLabel.text = NSLocalizedString(#"Header for the table", #"");
headerLabel.textColor = [UIColor whiteColor];
headerLabel.shadowColor = [UIColor yellowColor];
headerLabel.shadowOffset = CGSizeMake(0, 1);
headerLabel.font = [UIFont boldSystemFontOfSize:22];
headerLabel.backgroundColor = [UIColor clearColor];
[containerView addSubview:headerLabel];
self.tblSimpleTable.tableHeaderView = containerView;
}

why don’t you use UIScrollView for that.
I had tested your code & done required changes. Hope you like it.
Code :
(this is your .h file)
#import <UIKit/UIKit.h>
#interface tableScrollViewController : UIViewController
<UITableViewDelegate,UITableViewDataSource, UIScrollViewDelegate> {
UITableView *tblSimpleTable;
NSMutableArray *listOfItems;
NSMutableArray *appleComputers,*otherComputers;
UIScrollView *scrollView;
}
#end
(this is your .m file)
- (void)viewDidLoad {
[super viewDidLoad];
scrollView = [[UIScrollView alloc] initWithFrame:CGRectMake(0, 0, 320, 600)];
scrollView.delegate = self;
scrollView.backgroundColor = [UIColor grayColor];
scrollView.contentSize = CGSizeMake(300, 800);
appleComputers = [[NSMutableArray alloc] init]; // I made it by my style
[appleComputers addObject: #"iPhone"];
[appleComputers addObject:#"iPod"];
[appleComputers addObject:#"MacBook"];
[appleComputers addObject:#"MacBook Pro"];
otherComputers = [[NSMutableArray alloc] init];
[otherComputers addObject: #"HP"];
[otherComputers addObject:#"Dell"];
[otherComputers addObject:#"Windows"];
[otherComputers addObject:#"Sony"];
[otherComputers addObject:#"Ivory"];
[otherComputers addObject:#"IBM"];
self.navigationItem.title = #"Computers";
// Create a table
tblSimpleTable.delegate = self;
CGRect cgRct = CGRectMake(10, 50, 300, 600);
tblSimpleTable = [[UITableView alloc] initWithFrame:cgRct
style:UITableViewStyleGrouped]; // Initilize the table
[tblSimpleTable setBackgroundColor:[UIColor blackColor]];
tblSimpleTable.sectionHeaderHeight = 30.0;
tblSimpleTable.sectionFooterHeight = 30.0;
tblSimpleTable.scrollEnabled = NO;
tblSimpleTable.delegate = self;
tblSimpleTable.dataSource = self;
[scrollView addSubview:tblSimpleTable];
self.view = scrollView;
//Create the header
UIView *containerView = [[UIView alloc] initWithFrame:CGRectMake(0, 0, 300, 60)];
UILabel *headerLabel = [[UILabel alloc] initWithFrame:CGRectMake(10, 20, 300, 40)];
headerLabel.text = NSLocalizedString(#"Header for the table", #"");
headerLabel.textColor = [UIColor whiteColor];
headerLabel.shadowColor = [UIColor yellowColor];
headerLabel.shadowOffset = CGSizeMake(0, 1);
headerLabel.font = [UIFont boldSystemFontOfSize:22];
headerLabel.backgroundColor = [UIColor clearColor];
[containerView addSubview:headerLabel];
tblSimpleTable.tableHeaderView = containerView;
}
- (NSInteger)numberOfSectionsInTableView:(UITableView *)tableView
{
return 2;
}
// Customize the number of rows in the table view.
- (NSInteger)tableView:(UITableView *)tableView numberOfRowsInSection:(NSInteger)section
{
if(section == 0)
return [appleComputers count];
else if(section == 1)
return [otherComputers count];
}
// Customize the appearance of table view cells.
- (UITableViewCell *)tableView:(UITableView *)tableView
cellForRowAtIndexPath:(NSIndexPath *)indexPath
{
static NSString *CellIdentifier = #"Cell";
UITableViewCell *cell = (UITableViewCell *)[tableView
dequeueReusableCellWithIdentifier:CellIdentifier];
if(cell == nil)
{
cell = [[[UITableViewCell alloc] initWithFrame:CGRectZero
reuseIdentifier:CellIdentifier] autorelease];
}
if(indexPath.section == 0)
cell.text = [NSString stringWithFormat:#"%#“,
[appleComputers objectAtIndex:indexPath.row]];
else if(indexPath.section == 1)
cell.text = [NSString stringWithFormat:#"%#“,
[otherComputers objectAtIndex:indexPath.row]];
return cell;
}
- (void)tableView:(UITableView *)tableView didSelectRowAtIndexPath:
(NSIndexPath *)indexPath
{
// do whatever here
}
