How UITableView show two different arrays one at a time? - iphone

Question

The below Code works but not as i wish.i want that when i click UIbutton its automaically update the new value in UITableview instead of old value.Below Code works only when i press the UIbuttons and after that when i scroll the UITableview then it update the UItableview with new values.
In my application i using UITableview as Subclass of my mainclass.as image show below
I add Tableview in my Mainclass which is "testingViewController" like this way
In testingViewController.h
#import "Inputtableview.h"
#interface testingViewController :UIViewController<UITableViewDelegate,UITableViewDataSource> {
Inputtableview *inputview;
IBOutlet UITableView *inputtbl;
}
#end
In testingViewController.m
- (void)viewDidLoad {
btn1bool=FALSE;
if (inputview == nil) {
inputview = [[Inputtableview alloc] init];
}
[inputtbl setDataSource:inputview];
[inputtbl setDelegate:inputview];
inputview.view = inputview.tableView;
}
Now in Button action method
-(IBAction)input:(id)sender
{
btn1bool=TRUE;
}
my Subclass code "inputtableview.m" is show below
- (void)viewDidLoad {
[super viewDidLoad];
listOfItems=[[NSMutableArray alloc] initWithObjects:#"Iceland",#"Greenland",#"Switzerland",
#"Norway",#"New Zealand",#"Greece",#"Italy",#"Ireland",nil];
array1 = [[NSMutableArray alloc] initWithObjects:#"A",#"B",#"C",#"D",#"E",#"F",#"G",#"H", nil] ;
}
#pragma mark -
#pragma mark Table View datasource methods
-(NSInteger) tableView:(UITableView *)table numberOfRowsInSection:(NSInteger)section
{
if (btn1bool) {
return [array1 count];
}
else {
return [listOfItems count];
}
[self.tableView reloadData];
}
-(UITableViewCell *) tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath
{
static NSString *CellIdentifier = #"CellIdentifier";
UITableViewCell *cell = [tableView dequeueReusableCellWithIdentifier:CellIdentifier];
if (cell == nil) {
cell = [[[UITableViewCell alloc] initWithStyle:UITableViewCellStyleSubtitle reuseIdentifier:CellIdentifier] autorelease];
}
NSLog(#"Row: %i", indexPath.row);
if (btn1bool) {
NSString *cellValue = [array1 objectAtIndex:indexPath.row];
cell.text = cellValue;
}
else {
NSString *cellValue = [listOfItems objectAtIndex:indexPath.row];
cell.text = cellValue;
}
return cell;
}
Any help will be appriated.

Answer 1

Just put the following code:
[inputtbl reloadData];
There are a few things you need to change in your project, but I assume this project is just for testing stuff.
You want the date to reload after you pressed the button, so you call the method in the IBAction.
-(IBAction)input:(id)sender
{
btn1bool=TRUE;
[inputview.tableView reloadData];
}
To switch between the 2 data sources when the button is pressed you can change to this line of code: btn1bool=!btn1bool;
(NSInteger) tableView:(UITableView *)table numberOfRowsInSection:(NSInteger)section
{
if (btn1bool) {
return [array1 count];
} else {
return [listOfItems count];
}
}
-(UITableViewCell *) tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath is correct
