I'm trying to create a view programmatically which will have two views inside of it, one is for searching and the other one is a tableview which will shows photos;
But i'm having EXC_BAD_ACCESS error with code=2, all of the controller code is below. I suspected there is an infinite loop, but don't understand why.
Thanks for any help...
#interface PhotosViewController () <UITableViewDataSource, UITableViewDelegate>
#property (strong, nonatomic) UITableView *tableView;
#end
#implementation PhotosViewController
- (void)viewDidLoad {
[super viewDidLoad];
// Do any additional setup after loading the view.
self.title = #"Instagram";
[self.tableView registerClass:[PhotoTableViewCell class] forCellReuseIdentifier:CellIdentifier];
self.tableView.estimatedRowHeight = UITableViewAutomaticDimension;
self.tableView.allowsSelection = NO;
}

[super didReceiveMemoryWarning];
// Dispose of any resources that can be recreated.

_tableView.autoresizingMask = UIViewAutoresizingFlexibleHeight|UIViewAutoresizingFlexibleWidth;

_tableView.dataSource = self;
[_tableView reloadData];
[self.view addSubview:_tableView];
}

return cell;
}
- (CGFloat)tableView:(UITableView *)tableView heightForRowAtIndexPath:(NSIndexPath *)indexPath {

}
cell.namelabel.text = #"Mister Tester";
cell.dateLabel.text = #"2 hours ago";
}
In loadView should you not call [super loadView] or assign self.view first.
I believe reading self.view without that can cause an infinite loop.

I'm learning Xcode and programming for the IPad. I have a TableView and can display it using a button. I would rather display it when I click on a TextField. If I dismiss the first responder, the keyboard, how then do I display the tableView? I have not found a example that fits. Any direction would help.
It is just simple
just in UItextField delegate method create your tableview.But return No ,that will never show keyboard and write your tableview code there.
here your have to use user defined delegates.

I have a ViewController which has several subviews (Graphs) added using function
[self.view addSubview:subView]
Now, I want to add a UITableView as subview, but when I do this, my table is always empty. Methods like numberOfSectionsInTableView, numberOfRowsInSection, etc are never called.
My table doesn't have a XIB file. This is the code from my .M file:
#import "TableSubviewViewController.h"
#implementation TableSubviewViewController
#synthesize data;
#synthesize tableFrame;
-(id)initWithStyle:(UITableViewStyle)style{
self = [super initWithStyle:style];
if (self) {
// Custom initialization
}
return self;
}
-(void)viewDidLoad{
[super viewDidLoad];
self.view.frame = tableFrame;
}
-(NSInteger)numberOfSectionsInTableView:(UITableView *)tableView{
return [[self.data allKeys]count];
}
-(NSString*)tableView:(UITableView *)tableView titleForHeaderInSection:(NSInteger)section{
return [[self.data allKeys]objectAtIndex:section];
}
-(NSInteger)tableView:(UITableView *)tableView numberOfRowsInSection:(NSInteger)section{
return 1;
}
-(UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath{
static NSString *CellIdentifier = #"Cell";
UITableViewCell *cell = [tableView dequeueReusableCellWithIdentifier:CellIdentifier forIndexPath:indexPath];
if(cell == nil){
cell = [[UITableViewCell alloc]initWithStyle:UITableViewCellStyleDefault reuseIdentifier:CellIdentifier];
}
cell.textLabel.text = #"Some text";
return cell;
}
And this is the code in my main ViewController, in which I'm creating TableSubviewViewController:
TableSubviewViewController *tableSubView = [[TableSubviewViewController alloc]initWithStyle:UITableViewStyleGrouped];
tableSubView.tableFrame = tableFrame;
tableSubView.data = data;
[self.view addObject:tableSubView.view];
What Am I missing?
Thank you
TableSubviewViewController tableSubView must be main ViewController's global variable , can't be a local variable in the method viewDidLoad of main ViewController
U need to set datasource and delegate methods do like this
// in TableSubviewViewController.h file put a custom initilizer
#interface TableSubviewViewController : UIViewController
- (id)initTheSubviewTableVIewWithFrame:(CGRect)rect; //your custom initialiser
#end
//TableSubviewViewController.m file
#import "TableSubviewViewController.h"
#interface TableSubviewViewController ()<UITableViewDataSource,UITableViewDelegate>
#end
#implementation TableSubviewViewController
//dont use this method left blank
- (id)initWithNibName:(NSString *)nibNameOrNil bundle:(NSBundle *)nibBundleOrNil
{
self = [super initWithNibName:nibNameOrNil bundle:nibBundleOrNil];
if (self) {
// Custom initialisation
}
return self;
}
//you can make custom initiliser method
- (id)initTheSubviewTableVIewWithFrame:(CGRect)rect
{
self = [super init];
if(self)
{
UITableView *subViewTable = [[UITableView alloc]initWithFrame:rect];//since u are creating the tableview programatically u need to set datasource and delegate programatically
subViewTable.dataSource = self; //add this
subViewTable.delegate = self; //this also
[self.view addSubview:subViewTable];
}
return self;
}
- (void)viewDidLoad
{
[super viewDidLoad];
// Do any additional setup after loading the view from its nib.
}
- (void)didReceiveMemoryWarning
{
[super didReceiveMemoryWarning];
// Dispose of any resources that can be recreated.
}
//datasource and delegate methods
-(NSInteger)numberOfSectionsInTableView:(UITableView *)tableView{
return 2;
}
//use as reqired
//-(NSString*)tableView:(UITableView *)tableView titleForHeaderInSection: (NSInteger)section{
// return 3;
//}
-(NSInteger)tableView:(UITableView *)tableView numberOfRowsInSection:(NSInteger)section{
return 1;
}
-(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];
}
cell.textLabel.text = #"Some text";
return cell;
}
//in main ViewController.m controler u need to do like this
TableSubviewViewController *subViewTable = [[TableSubviewViewController alloc]initTheSubviewTableVIewWithFrame:CGRectMake(self.view.bounds.origin.x, self.view.bounds.origin.y, self.view.bounds.size.width, 150)];//created the subviewTableView tableview
//set properties that u defined for tableview delegate and datasource
[self.view addSubview:subViewTable.view];
hope this helps u :)
Make sure your .h file use
and set delegate and datasource to self.
TableSubviewViewController *tableSubView = [[TableSubviewViewController alloc]initWithStyle:UITableViewStyleGrouped];
tableSubView.tableFrame = tableFrame;
tableSubView.delegate = self;
tableSubView.dataSource = self;
tableSubView.data = data;
[self.view addObject:tableSubView.view];
After that check whether array self.data have object or not. It might be possible that array is blank.
Why isn't the numberOfSectionsInTableView method not being called? It's called if I add [self.tableView reloadData] in viewDidLoad, but even then, cellForRow does not get called.
Edit: I updated the following code to register the nib for the UITableViewCell.
In a UIViewController, I have:
- (void)viewDidLoad
{
[super viewDidLoad];
XXFeedTableViewController *tableViewController = [[XXFeedTableViewController alloc] initWithStyle:UITableViewStylePlain];
tableViewController.view.frame = self.view.bounds;
[self addChildViewController:tableViewController];
}
XXFeedTableViewController.h
#interface XXFeedTableViewController : UITableViewController
#end
XXFeedTableViewController.m
#import "XXFeedTableViewController.h"
#import "XXFeedTableViewCell.h"
#interface XXFeedTableViewController ()
#end
#implementation XXFeedTableViewController
- (id)initWithStyle:(UITableViewStyle)style {
self = [super initWithStyle:style];
if (self) {
}
return self;
}
- (void)viewDidLoad {
[super viewDidLoad];
[self.tableView registerNib:[UINib nibWithNibName:#"XXFeedTableViewCell" bundle:nil] forCellReuseIdentifier:#"XXFeedTableViewCell"];
}
#pragma mark - Table view data source
- (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 = #"XXFeedTableViewCell";
XXFeedTableViewCell *cell = [tableView dequeueReusableCellWithIdentifier:CellIdentifier forIndexPath:indexPath];
cell.textLabel.text = #"Hey";
return cell;
}
#end
Apple docs say:
If no nib file is specified or if the nib file defines no data source
or delegate, UITableViewController sets the data source and the
delegate of the table view to self. When the table view is about to
appear the first time it’s loaded, the table-view controller reloads
the table view’s data.
Try this, and see if it works. This is the way Apple recommends now with a nib based cell.
-(void)viewDidLoad {
[super viewDidLoad];
[self.tableView registerNib:[UINib nibWithNibName:#"XXFeedTableViewCell" bundle:nil] forCellReuseIdentifier:#"XXFeedTableViewCell"];
}
- (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 = #"XXFeedTableViewCell";
ROFeedTableViewCell *cell = [tableView dequeueReusableCellWithIdentifier:CellIdentifier forIndexPath:indexPath];
cell.textLabel.text = #"Hey";
return cell;
}
After Edit:
In your initial controller, you should add the table view controller as a child controller before you add its subview:
XXFeedTableViewController *tableViewController = [[XXFeedTableViewController alloc] initWithStyle:UITableViewStylePlain];
self addChildViewController:tableViewController];
tableViewController.view.frame = self.view.bounds;
[self.view addSubview:tableViewController.view];
[tableViewController didMoveToParentViewController:self];
I have an iphone app that I'm trying to make a universal app. I created a separate project to play around with creating a split view app for iPad. I got the basics of it working so I'm trying to implement it in my existing project but I'm getting an error when running on iPad.
2013-06-06 08:57:08.716 KFBNewsroom[26898:c07] *** Terminating app due to uncaught exception 'NSInternalInconsistencyException', reason: '-[UITableViewController loadView] loaded the "KFBMasterViewController" nib but didn't get a UITableView.'
The code for the split view is the same as it was in my test project so I can't figure out why it won't work here. Any ideas?

You probably have to change the super-class of your rootViewController from UITableViewController to UIViewController.
My application starts with Root controller called TaskController : UINavigationController as as root view controller of UINavigationController i created class
TaskRootController : UIViewController<UITableViewDelegate> (it has add as view UITableView); When I start application i see only Title form TaskRootController and background color from it. But I don't see table view. If my application starts with TaskRootController as a rootViewController I see table view.
How can I make to see table view in may case ?
PS. Even if I switch TaskRootController to TaskRootController : UITableViewController the behavior is the same.
my code is below:
AppDelegate.m
#implementation AppDelegate
#synthesize window = _window;
#synthesize taskController;
- (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions
{
self.window = [[UIWindow alloc] initWithFrame:[[UIScreen mainScreen] bounds]];
// Override point for customization after application launch.
self.window.backgroundColor = [UIColor whiteColor];
self.taskController = [TaskController alloc];
self.window.rootViewController = self.taskController;
[self.window makeKeyAndVisible];
return YES;
}
- (void)applicationWillResignActive:(UIApplication *)application
{
}
- (void)applicationDidEnterBackground:(UIApplication *)application
{
}
- (void)applicationWillEnterForeground:(UIApplication *)application
{
}
- (void)applicationDidBecomeActive:(UIApplication *)application
{
}
- (void)applicationWillTerminate:(UIApplication *)application
{
}
#end
TaskController.m
#implementation TaskController
#synthesize taskRootController;

{
self = [super initWithNibName:nibNameOrNil bundle:nibBundleOrNil];
if (self) {

[self.navigationBar setBarStyle: UIBarStyleBlack];
[self.navigationBar setTranslucent: NO];
}
return self;
}
- (void)viewDidLoad
{
[super viewDidLoad];
// Do any additional setup after loading the view.
self.taskRootController = [[TaskRootController alloc] initWithNibName:nil bundle:NULL];
UIViewController *root = self.taskRootController;

self.taskRootView.dataSource = self;
[self.view addSubview:self.taskRootView];
}

return 1; // put number for section.
}
- (NSInteger)tableView:(UITableView *)tableView numberOfRowsInSection:(NSInteger)section {
// Return the number of rows in the section.
return 6; // put number as you want row in section.
}
- (CGFloat) tableView:(UITableView *)tableView heightForRowAtIndexPath:(NSIndexPath *)indexPath
{
CGFloat result = 20.0f;
if([tableView isEqual:self.taskRootView])
{
result = 40.0f;
}
return result;
}
#end
Add this delegate method .
- (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];
}
cell.textLabel.text = #"this is row";
return cell;
}
EDIT :
put init at when you create object of TaskController in AppDelegate.m
self.taskController = [[TaskController alloc]init];
And also put both delegate and datasource to TaskController.h
<UITableViewDataSource, UITableViewDelegate>
and add its relavent methods.
In your AppDelegate
self.taskController = [[TaskController alloc]initWithNibName:#"TaskController" bundle:[NSBundle mainBundle]];
UINavigationController *task = [[UINavigationController alloc] initWithRootViewController:self.taskController];
self.window.rootViewController = task;
In your TaskController
- (void)viewDidLoad
{
[super viewDidLoad];
TaskRootController *tc = [[TaskRootController alloc] initWithNibName:#"TaskRootController" bundle:[NSBundle mainbundle]];
[self addChildViewController:tc];
[tc didMoveToParentViewController:self];
[self.view addSubview:tc.view];
}
Try this ::
set delegate and datasource of your tableview
-(CGFloat)tableView:(UITableView *)tableView heightForRowAtIndexPath:(NSIndexPath *)indexPath
{
return 50;
}
- (NSInteger)numberOfSectionsInTableView:(UITableView *)tableView
{
return 1;
}
- (NSInteger)tableView:(UITableView *)tableView numberOfRowsInSection:(NSInteger)section{
return [yourArray count];
}
- (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath{
static NSString *MyIdentifier = #"MyIdentifier";
UITableViewCell *cell =[tableView dequeueReusableCellWithIdentifier:MyIdentifier];
if (cell == nil){
cell = [[[UITableViewCell alloc] initWithFrame:CGRectZero reuseIdentifier:MyIdentifier] autorelease];
}
cell.textLabel.text = #"row";
return cell;
}
Hope it will help you
in Appdelegate File :-
self.TaskViewController = [[TaskViewController alloc] initWithNibName:#"TaskViewController" bundle:nil];
self.navigationController=[[UINavigationController alloc]initWithRootViewController:self.TaskViewController];
[self.window setRootViewController:navigationController];//ios-6
or
[self.window addSubview:navigationController.view];//<ios-6
Add a Delegate Method in UITableViewDelagates:-
- (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];
}
cell.textLabel.text = #"Name";
return cell;
}
