iPhone Multiple UITableView controls on one View - iphone

Im having a little issue with using more than 1 UITableView on a view.
Here's what I've done so far (using examples, etc from here and other places):
Created a class for each table. Each class is pretty basic:
.h:
#interface ConstructionDocumentsJobTable : UITableViewController <UITableViewDataSource, UITableViewDelegate> {
NSMutableArray *tableItems;
IBOutlet UITableView *itemsTable;
NSInteger recordSelected;
id <JobTableSelectionDelegate> tableSelectDelegate;
}
#property (nonatomic, retain) NSMutableArray *tableItems;
#property (nonatomic, assign) id <JobTableSelectionDelegate> tableSelectDelegate;
#end
.m:
#implementation ConstructionDocumentsJobTable
#synthesize tableItems, tableSelectDelegate;
#pragma mark -
#pragma mark View Life Cycle
-(void) loadView
{
}
-(void) dealloc
{
[tableItems release];
[super dealloc];
}
#pragma mark -
#pragma mark Table view data source
// Customize the number of sections in the table view.
- (NSInteger)numberOfSectionsInTableView:(UITableView *)tableView {
return 1;
}
// Customize the number of rows in the table view.
- (NSInteger)tableView:(UITableView *)tableView numberOfRowsInSection:(NSInteger)section {
return [tableItems count];
}
// Customize the appearance of table view cells.
- (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath {
static NSString *CellIdentifier = #"Cell";
UITableViewCell *cell = [tableView dequeueReusableCellWithIdentifier:CellIdentifier];
if (cell == nil) {
cell = [[[UITableViewCell alloc] initWithStyle:UITableViewCellStyleDefault reuseIdentifier:CellIdentifier] autorelease];
}
cell.textLabel.text = [tableItems objectAtIndex:indexPath.row];
return cell;
}
#pragma mark -
#pragma mark Table view delegate
- (void)tableView:(UITableView *)tableView didSelectRowAtIndexPath:(NSIndexPath *)indexPath {
//pass the tap value back to the delegate
}
Both are completely identical, save the names.
When Im making the call to the first one, it is called in the ViewDidLoad method of the controller of the view. It's pretty basic:
NSMutableArray *tableItems = [[NSMutableArray alloc] initWithCapacity:intMax];
//strDocumentType is set elsewhere and loaded here
if(strDocumentType == #"typea"){
[tableItems addObject:#"Type A - Value 1"];
[tableItems addObject:#"Type A - Value 2"];
}
else {
[tableItems addObject:#"Type B - Value 1"];
}
if(jobTableController == nil){
jobTableController = [[ConstructionDocumentsJobTable alloc] init];
[jobTableController loadView];
jobTableController.tableItems = tableItems;
jobTableController.tableSelectDelegate = self;
}
[tableJobList setDataSource:jobTableController];
[tableJobList setDelegate:jobTableController];
jobTableController.view = jobTableController.tableView;
The second table is built when a cell in the first table is selected. So, in the first tables selection method, the delegate is called back from the parent controller, which then has this:
NSMutableArray *tableTypeItems = [[NSMutableArray alloc] initWithCapacity:100];
if(tableSelect == #"plumbing"){
[tableTypeItems addObject:#"Something"];
[tableTypeItems addObject:#"Other"];
}
if(typeTableController == nil){
typeTableController = [[ConstructionDocumentsTypeTable alloc] init];
[typeTableController loadView];
typeTableController.tableItems = tableTypeItems;
typeTableController.tableSelectDelegate = self;
}
[tableTypeList setDataSource:typeTableController];
[tableTypeList setDelegate:typeTableController];
typeTableController.view = typeTableController.tableView;
[typeTableController.tableView reloadData];
//Code to move the first table off the screen and move this one into view goes here
Ive been stuck on this for days, and I really need to get this done!!!
Im sure it's something REALLLLLLY simple.
Any help you guys can pass along would be HUGELY appreciated.
Thanks everyone.

Your only defining itemsTable in your header, try defining another table, and in your cellForRowAtIndexPath try this:
if(itemsTable1){
/* stuff for first table */
} else {
/* stuff for second table */
}
And do the same for each UITableVIew Delegate

Create a two tableview list using one TableViewController class

I want to do an sample application where in a view i have two buttons one is COUNTRY and another is STATE.
when i click on a country button the country list should appear in a tableview class like a popup and when i click on state button state list should appear in a tableview like popup,So how can i do this please suggest with sample code.
NOTE:I should use only one TableViewcontroller class for both country and state Data list.
Here is the Code:
RootViewController.h
#interface RootViewController : UIViewController {
UIButton *btnCountry;
UIButton *btnState;
NSMutableArray *tempArray;
NSMutableArray *countryArray;
NSMutableArray *stateArray;
IBOutlet UITableView *tempTable;
}
#property (nonatomic,retain) UIButton *btnCountry;
#property (nonatomic,retain) UIButton *btnState;
#property (nonatomic,retain) NSMutableArray *countryArray;
#property (nonatomic,retain) NSMutableArray *stateArray;
#property (nonatomic,retain) NSMutableArray *tempArray;
#property (nonatomic,retain) UITableView *tempTable;
- (IBAction) showState:(id)sender;
- (IBAction) showCountry:(id)sender;
#end
RootViewController.m
#implementation RootViewController
#synthesize btnState,btnCountry, stateArray,countryArray,tempArray;
#synthesize tempTable;
#pragma mark -
#pragma mark View lifecycle
- (void)viewDidLoad {
[super viewDidLoad];
tempTable.hidden = YES;
countryArray = [[NSMutableArray alloc]initWithObjects:#"India",#"Pakistan",#"USA",nil];
stateArray = [[NSMutableArray alloc]initWithObjects:#"Gujarat",#"Maharashtra", #"Karnataka",nil];
tempArray = [[NSMutableArray alloc]init];
}
- (IBAction) showCountry:(id)sender
{
btnCountry = (UIButton *)sender;
tempArray = countryArray;
[tempTable reloadData];
if([btnCountry isSelected])
{
tempTable.hidden = YES;
btnCountry.selected = NO;
}
else
{
tempTable.hidden = NO;
btnCountry.selected = YES;
}
}
- (IBAction) showState:(id)sender
{
btnState = (UIButton *)sender;
tempArray = stateArray;
[tempTable reloadData];
if([btnState isSelected])
{
tempTable.hidden = YES;
btnState.selected = NO;
}
else
{
tempTable.hidden = NO;
btnState.selected = YES;
}
}
- (NSInteger)numberOfSectionsInTableView:(UITableView *)tableView {
return 1;
}
// Customize the number of rows in the table view.
- (NSInteger)tableView:(UITableView *)tableView numberOfRowsInSection:(NSInteger)section {
return [tempArray count];
}
// Customize the appearance of table view cells.
- (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath {
static NSString *CellIdentifier = #"Cell";
UITableViewCell *cell = [tableView dequeueReusableCellWithIdentifier:CellIdentifier];
if (cell == nil) {
cell = [[[UITableViewCell alloc] initWithStyle:UITableViewCellStyleDefault reuseIdentifier:CellIdentifier] autorelease];
}
cell.textLabel.text = [tempArray objectAtIndex:indexPath.row];
return cell;
}
#end
The question is not clear enough ,, what did you try? ..
But, You can use UIPopOverController for that
see
THIS LINK
Or Just a Static UiTableView in the same Nib file ,, make it hidden when you don't need it .
You can use One Tableview for this: Here i am attaching only the logic.
In viewdidload,
There will be two arrays countryArray and stateArray.
There will be a third array : tempArray
there are two buttons: button1 and button2
tableview.hidden=YES;
in button1Action assign the countryArray to tempArray and also [tableview reload]
in button2Action assign the stateArray to tempArray and also [tableview reload]
then in tableview delegates,
(NSInteger)tableView:(UITableView *)table numberOfRowsInSection:(NSInteger)section
{
return [tempArray count];
}
and then in
(UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath{
use tempArray.......
}
try this...and if you want more detailed pls inform....
Take Two tableViews and two Buttons.
Place each tableview below each of the button.
Initially both the TableViews are hidden. When the Button is clicked show the TableView with Animation.
I think you should only use one TableViewController but with different data sources.

Table view controller on view controller

I am creating an app in which i want to display a text box and when i enter an word in it ,then it will display the contents from the dictionary which are matching to that word.Now i want to display the list which will generate from my dictionary according to the word entered in text box ,in a table view and that table view should be on the same view controller where i am having the text box.Is it possible to do so. I mean is it possible to create a table view with scrolling option so that user can scroll through the list and then select the word which he wants.
Yes it is possible. Take IBOutlet for UITableView and wire it up. Define its datasource and delegate to your controller. Implement UITableViewDelegate to your controller and override all the methods like cellForRowAtIndex and others.
//FilterDataViewController.h
#import <UIKit/UIKit.h>
#interface FilterDataViewController : UIViewController <UITableViewDelegate>
{
IBOutlet UITableView *tblView;
IBOutlet UITextField *txtFld;
NSMutableArray *arrSrch;
NSMutableArray *srchedData;
}
-(IBAction)srchBtnTapped:(id)sender;
#end
//FilterDataViewController.m
#import "FilterDataViewController.h"
#implementation FilterDataViewController
-(IBAction)srchBtnTapped:(id)sender
{
if(![txtFld.text isEqualToString:#""])
{
[srchedData removeAllObjects];
for (NSString *allStrings in arrSrch)
{
NSComparisonResult result = [allStrings compare:txtFld.text options:(NSCaseInsensitiveSearch|NSDiacriticInsensitiveSearch) range:NSMakeRange(0, [txtFld.text length])];
if (result == NSOrderedSame)
{
[srchedData addObject:allStrings];
}
}
[tblView reloadData];
}
}
// Implement viewDidLoad to do additional setup after loading the view, typically from a nib.
- (void)viewDidLoad {
[super viewDidLoad];
arrSrch = [[NSMutableArray alloc] initWithObjects:#"One",#"One Two",#"Two",#"Three",#"Four",#"One Five",#"Six",nil];
srchedData = [[NSMutableArray alloc] init];
}
#pragma mark -
#pragma mark Table view data source
// Customize the number of sections in the table view.
- (NSInteger)numberOfSectionsInTableView:(UITableView *)tableView {
return 1;
}
// Customize the number of rows in the table view.
- (NSInteger)tableView:(UITableView *)tableView numberOfRowsInSection:(NSInteger)section {
return [srchedData count];
}
// Customize the appearance of table view cells.
- (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath {
static NSString *CellIdentifier = #"Cell";
UITableViewCell *cell = [tableView dequeueReusableCellWithIdentifier:CellIdentifier];
if (cell == nil) {
cell = [[[UITableViewCell alloc] initWithStyle:UITableViewCellStyleDefault reuseIdentifier:CellIdentifier] autorelease];
}
cell.textLabel.text = [srchedData objectAtIndex:indexPath.row];
// Configure the cell.
return cell;
}
#end
This is surely possible. Create a View based Application and put both of your table view and Text Field in the same view and you can do what ever you are planning to do.

UITableView as a subview?

Is this possible? I just want a small table in my current view... here is what I'm trying to do:
.h file
#import <UIKit/UIKit.h>
#interface IngredientsRootView : UIViewController <UITableViewDelegate, UITableViewDataSource> {
UITableView *ingredientsTable;
}
#property (nonatomic, retain) UITableView *ingredientsTable;
#end
.m file I have delegate and data source methods and this code:
ingredientsTable = [[UITableView alloc] initWithFrame:CGRectMake(10, 10, 300, 300) style:UITableViewStylePlain];
[ingredientsTable setDelegate:self];
[ingredientsTable setDataSource:self];
[self.view addSubview:ingredientsTable];
The app doesn't crash, but it doesn't show a table. At the moment I have just set everything definitely as per:
#pragma mark -
#pragma mark Table view data source
- (NSInteger)numberOfSectionsInTableView:(UITableView *)tableView {
// Return the number of sections.
return 1;
}
- (NSInteger)tableView:(UITableView *)tableView numberOfRowsInSection:(NSInteger)section {
// Return the number of rows in the section.
return 10;
}
// the appearance of table view cells.
- (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath {
static NSString *CellIdentifier = #"Cell";
UITableViewCell *cell = [tableView dequeueReusableCellWithIdentifier:CellIdentifier];
if (cell == nil) {
cell = [[[UITableViewCell alloc] initWithStyle:UITableViewCellStyleDefault reuseIdentifier:CellIdentifier] autorelease];
}
// Configure the cell...
cell.textLabel.text = #"Hello";
return cell;
}
What am I doing wrong? Thanks
Try calling -reloadData on the table view after adding it as a subview.
Also, how is the view set up? Is it created in a XIB or via -loadView?
Did you remembered to add the [window addSubview:[IngredientsRootView view]]; to your app delegate ?
And by the way, instead of inheriting from UIViewController you can just inherit from UITableViewController and you'll get all that functionality for you with no added code.

UITableView not getting populated

I have a peculiar problem. I created a normal Objective C class called SampleTable. I then extended UITableView instead of NSObject. Then in the initWithFrame constructor I initialized the table. I also made a NSMutableArray object for the datasource. I also conformed UITableViewDelegate and UITableViewDatasource. I have overridden the necessary methods also.
Now I made an object of this class in another class, and added the object as a subview. The tableView is getting drawn according to the CGRectMake() coordinates I gave to the initWithFrame constructor. But it is not getting populated with the data. I don't know what the problem is.
SampleTable.h
#import <Foundation/Foundation.h>
#interface SampleTable : UITableView {
NSMutableArray *ItemArray;
}
#property (nonatomic,retain) NSMutableArray *ItemArray;
-(NSMutableArray *) displayItemArray;
#end
SampleTable.m
#import "SampleTable.h"
#implementation SampleTable
#synthesize ItemArray;
-(id)initWithFrame:(CGRect)frm {
[super initWithFrame:frm];
self.delegate=self;
self.dataSource=self;
[self reloadData];
return self;
}
-(NSMutableArray *) displayItemArray {
if(ItemArray==nil) {
ItemArray=[[NSMutableArray alloc] initWithObjects:#"1",#"2",#"3",#"4",#"5",nil];
}
return ItemArray;
}
- (NSInteger)numberOfSectionsInTableView:(UITableView *)tableView
{
return 1;
}
-(NSInteger)tableView:(UITableView *)tableView numberOfRowsInSection:(NSInteger)section {
return [ItemArray count];
}
-(UITableViewCell *)tableView: (UITableView *)tableView cellForRowAtIndexPath: (NSIndexPath *)indexPath {
static NSString *CellIdentifier = #"Cell";
UITableViewCell *cell= [tableView dequeueReusableCellWithIdentifier:CellIdentifier];
if (cell==nil) {
cell = [[UITableViewCell alloc] initWithStyle:UITableViewCellStyleSubtitle reuseIdentifier:CellIdentifier];
[cell autorelease];
}
NSString *temp=[self.ItemArray objectAtIndex:indexPath.row];
cell.textLabel.text = temp;
return cell;
}
- (void)tableView:(UITableView *)tableView didSelectRowAtIndexPath:(NSIndexPath *)indexPath {
NSLog(#"didselect");
}
-(void) dealloc {
[ItemArray release];
[super dealloc];
}
#end
You did never initialize the ItemArray within your code snippet. Remove the displayItemData method and change the initializer towards:
-(id)initWithFrame:(CGRect)frm
{
if ((self = [super initWithFrame:frm])) != nil)
{
self.delegate=self;
self.dataSource=self;
ItemArray=[[NSMutableArray alloc] initWithObjects:#"1",#"2",#"3",#"4",#"5",nil];
[self reloadData];
}
return self;
}
You could also simply call that displayItemArray method within the initializer. I feel that method makes no sense as it stands and hence my recommendation to remove it altogether.
Without trying it myself, I am still pretty confident that you can also get rid of that [self reloadData] within the initializer.
During the -(id)initWithFrame:(CGRect)frm method your code calls -reloadData on the UITableView. At this point in time your ItemArray is not available.
Therefore, when UITableView calls it's delegates -numberOfSectionsInTableView: and -tableView:numberOfRowsInSection: methods to get information on what to display in the view, they return one section with zero rows.
Nothing displayed!
It might be a (one) solution to change your initialization of the ItemArray:
-(NSMutableArray *) displayItemArray {
if(ItemArray==nil) {
ItemArray=[[NSMutableArray alloc] initWithObjects:#"1",#"2",#"3",#"4",#"5",nil];
[self reloadData];
}
return ItemArray;
}
print value of
[self.ItemArray objectAtIndex:indexPath.row];
in NSLog... check wether it prints valid value or not....It seems that array's object releasing somewhere before it..

having two table views in a single xib one of plain style and the other grouped styled

I want to use two tableviews under the segmentedcontrol. one is plain styled and the other is groupstyled. How can i controll the delegate and datasource for the two table views?

HI,
I have to inserted the data into table view by using sqlite.But now i need that data in to two table views in next view..I have arranged segmented bar.Am getting two table views but the values in r not displaying.It is displaying NULL.
Using multiple or two exclusive table in the save UI view controller sharing the same data source.
I face a problem like this, if anybody needs later...
I try to set my ViewController as a datasource for two different table. But it did not work. 2 tables are exclusively shown at loadtime of the view. Either one will be hidden in viewDidLoad depending on a flag. Seems once dataSource is called for one table, it's not called for the 2nd table. All connections are set in IB.
The solution is to set the dataSource in code in viewDidLoad. Then it works.
-(void) viewDidLoad(){
table1.dataSource = self;
table2.dataSource = self;
if(someCondition == YES)
table1.visible = NO;
else
table2.visible = NO;
}
Since you can't change the UITableViewStyle of a UITableView once created (it can only be set at construction time), you have to have two different instances. You can do this in very different ways, but I've done it this way: add a UISegmentedControl to your interface, and set its target to the RootViewController class instance in your application. The RootViewController class could look like this:
#class DataSource;
#interface RootViewController : UITableViewController
{
#private
UITableView *_originalTableView;
UITableView *_secondaryTableView;
DataSource *_dataSource;
BOOL _showingSecondaryTableView;
}
- (IBAction)swap:(id)sender;
#end
And this might be the implementation:
#import "RootViewController.h"
#import "DataSource.h"
#implementation RootViewController
- (void)dealloc
{
[_dataSource release];
[_originalTableView release];
[_secondaryTableView release];
[super dealloc];
}
- (void)viewDidLoad
{
[super viewDidLoad];
_dataSource = [[DataSource alloc] init];
_secondaryTableView = [[UITableView alloc] initWithFrame:self.tableView.frame
style:UITableViewStyleGrouped];
_secondaryTableView.delegate = _dataSource;
_secondaryTableView.dataSource = _dataSource;
_originalTableView = [self.tableView retain];
_showingSecondaryTableView = NO;
}
- (void)didReceiveMemoryWarning
{
[super didReceiveMemoryWarning];
}
#pragma mark -
#pragma mark IBAction method
- (IBAction)swap:(id)sender
{
if (_showingSecondaryTableView)
{
self.tableView = _originalTableView;
_showingSecondaryTableView = NO;
}
else
{
self.tableView = _secondaryTableView;
_showingSecondaryTableView = YES;
}
}
#pragma mark -
#pragma mark Table view methods
- (NSInteger)numberOfSectionsInTableView:(UITableView *)tableView
{
return 1;
}
- (NSInteger)tableView:(UITableView *)tableView
numberOfRowsInSection:(NSInteger)section
{
return 5;
}
- (UITableViewCell *)tableView:(UITableView *)tableView
cellForRowAtIndexPath:(NSIndexPath *)indexPath
{
static NSString *CellIdentifier = #"Cell";
UITableViewCell *cell = [tableView dequeueReusableCellWithIdentifier:CellIdentifier];
if (cell == nil)
{
cell = [[[UITableViewCell alloc] initWithStyle:UITableViewCellStyleDefault
reuseIdentifier:CellIdentifier] autorelease];
}
cell.textLabel.text = [NSString stringWithFormat:#"RootViewController cell %d", indexPath.row];
return cell;
}
#end
This is the interface of the DataSource class:
#import <UIKit/UIKit.h>
#interface DataSource : NSObject <UITableViewDelegate,
UITableViewDataSource>
{
}
#end
And the implementation:
#import "DataSource.h"
#implementation DataSource
#pragma mark -
#pragma mark Table view methods
- (NSInteger)numberOfSectionsInTableView:(UITableView *)tableView
{
return 2;
}
- (NSInteger)tableView:(UITableView *)tableView
numberOfRowsInSection:(NSInteger)section
{
return 3;
}
- (UITableViewCell *)tableView:(UITableView *)tableView
cellForRowAtIndexPath:(NSIndexPath *)indexPath
{
static NSString *CellIdentifier = #"DataSourceCell";
UITableViewCell *cell = [tableView dequeueReusableCellWithIdentifier:CellIdentifier];
if (cell == nil)
{
cell = [[[UITableViewCell alloc] initWithStyle:UITableViewCellStyleDefault
reuseIdentifier:CellIdentifier] autorelease];
}
cell.textLabel.text = [NSString stringWithFormat:#"DataSource cell %d", indexPath.row];
return cell;
}
#end
You can change the datasource and delegate of the UITableView instances to anything you want, at any time during runtime, which might help you encapsulate different data sources with separate controllers.
Hope this helps!
