UITableViewCell subclass throwing an unrecognized selector sent to instance - uitableview

My UITableViewCell is giving a -[UITableViewCell nameTeam]: unrecognized selector sent to instance.
I created a PlayerStatsTableViewCell.xib with a UITableViewCell and UILabel. Set the Custom Class to "PlayerStatsTableViewCell" and its Table View Cell identifier to "playerStats"
PlayerStatsTableViewCell.h
#interface PlayerStatsTableViewCell : UITableViewCell
#property (weak, nonatomic) IBOutlet UILabel *nameTeam;
#end
PlayerStatsTableViewCell.m
#implementation PlayerStatsTableViewCell
#synthesize nameTeam;
- (void)awakeFromNib {
// Initialization code
}
- (void)setSelected:(BOOL)selected animated:(BOOL)animated {
[super setSelected:selected animated:animated];
// Configure the view for the selected state
}
In my PlayerStatsTableViewController, cell.nameTeam is throwing the error
- (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath {
PlayerStatsTableViewCell *cell = (PlayerStatsTableViewCell *)[tableView dequeueReusableCellWithIdentifier:#"playerStats"];
[tableView registerNib:[UINib nibWithNibName:#"PlayerStatsTableViewCell" bundle:nil] forCellReuseIdentifier:#"playerStats"];
cell.nameTeam.text = #"PLEASE";
return cell;
}
PlayerStatsTableViewCell.xib showing Custom Class and Identifier
The error message
PlayerStatsTableViewController from Storyboard

- (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath {
PlayerStatsTableViewCell *cell = (PlayerStatsTableViewCell *)[tableView dequeueReusableCellWithIdentifier:#"playerStats"];
if (cell == nil) {
NSArray *nib = [[NSBundle mainBundle] loadNibNamed:#"PlayerStatsTableViewCell" owner:self options:nil];
cell = (PlayerStatsTableViewCell *)[nib objectAtIndex:0];
}
cell.nameTeam.text = #"PLEASE";
return cell;
}

can't load tableview with custom cell

I'm using Objective-C. I want to push a view controller with a table view in it. When I use a normal table view cell, it works well. But when I use custom cells, It couldn't load and the simulator freeze.
Is there any problem can cause the simulator freeze when push a view controller? Some one can help me?

You need to register your custom cell in viewdidload
- (void)viewDidLoad {
[super viewDidLoad];
// Do any additional setup after loading the view from its nib.
[tableView registerNib:[UINib nibWithNibName:#"myCustomCell" bundle:nil] forCellWithReuseIdentifier:#"myCell"];
}
try these way..
- (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath;
{
NSString *cellidentifier=[NSString stringWithFormat:#"%ld",(long)indexPath.row];
CustomCell *cell= (CustomCell *)[tableView dequeueReusableCellWithIdentifier:cellidentifier];
if (cell==nil)
{
cell=[[CustomCell alloc]initWithStyle:UITableViewCellStyleDefault reuseIdentifier:cellidentifier];
[cell setSelectionStyle:UITableViewCellSelectionStyleNone];
}
if (indexPath.row==0)
{
//Here change or edit specific custom cell if u want like i have UIImageview and i want to give it a specific image..
[cell.imgView1 setImage:imgsp1];
}
return cell;
}
i hope it helps..

Exception at cellForRowAtIndexPath function - UITableView

I want to display a list of data on "UITableView".
When I run the code I get the following error:
*** Terminating app due to uncaught exception 'NSInternalInconsistencyException', reason:
'unable to dequeue a cell with identifier Cell - must register a nib or a class for the
identifier or connect a prototype cell in a storyboard'
I get the error given above when I run the code below. The error is thrown at the
cellForRowAtIndexPath function. How can I solve this error?
#interface TheViewController ()
#property (strong, nonatomic) NSMutableArray *myTData;
#property (weak, nonatomic) IBOutlet UITableView *tableViewOutlet;
#end
#implementation TheViewController
- (void)viewDidLoad
{
self.tableViewOutlet.delegate = self;
self.tableViewOutlet.dataSource = self;
self.tableViewOutlet.scrollEnabled = YES;
self.myData = [[NSMutableArray alloc] initWithObjects:#"obj1", #"obj2", nil];
[self.tableViewOutlet reloadData];
[super viewDidLoad];
}
#pragma mark UITableViewDataSource methods
- (NSInteger)tableView:(UITableView *)tableView numberOfRowsInSection:(NSInteger) section {

UITableViewCell *cell = [tableView dequeueReusableCellWithIdentifier:CellIdentifier forIndexPath:indexPath];
if (cell == nil) {
cell = [[UITableViewCell alloc]
initWithStyle:UITableViewCellStyleDefault reuseIdentifier:#"hede"];
}
[cell.textLabel setText: [myData objectAtIndex:indexPath.row]];
[cell.detailTextLabel setText:#"hede hodo"];
//
// Configure the cell..
return cell;
}
#pragma mark UITableViewDelegate methods
- (void)tableView:(UITableView *)tableView didSelectRowAtIndexPath:(NSIndexPath *)indexPath {

}
#pragma mark - Table view data source

{
#warning Potentially incomplete method implementation.
// Return the number of sections.
return 1;
}
#end
The exception is exactly what it says it is.
In iOS 5, you would call [tableView dequeueReusableCellWithIdentifier:CellIdentifier] and if it didn't return one, you would create one. The new call -dequeueReusableCellWithIdentifier:forIndexPath: should have a NIB or cell class registered and it will then always succeed.
You should call either
- (void)registerNib:(UINib *)nib forCellReuseIdentifier:(NSString *)identifier
or
- (void)registerClass:(Class)cellClass forCellReuseIdentifier:(NSString *)identifier
in your -viewDidLoad method.
In your storyboard, select the prototype cell, go to inspector and give the cell the identifier "Cell" or whatever you want as long as you have the same here : static NSString *CellIdentifier = #"Cell";

Content in UITableViewCell is not showing

I am having trouble with a UITableViewCell.
I have a view controller in my storyboard that is connected to my view controller called MainViewController. It Contains a UITableViewCell with 3 labels. The UITableViewCell is connected to the class MTTableViewCell.
// MTTableViewCell.h
#import <UIKit/UIKit.h>
#interface MTTableViewCell : UITableViewCell
#property (strong, nonatomic) IBOutlet UILabel *mainLabel;
#property (strong, nonatomic) IBOutlet UILabel *statusLabel;
#end
// MTTableViewCell.m
#import "MTTableViewCell.h"
#implementation MTTableViewCell
- (id)initWithStyle:(UITableViewCellStyle)style reuseIdentifier:(NSString *)reuseIdentifier {
self = [super initWithStyle:style reuseIdentifier:reuseIdentifier];
if (self) {
// Initialization code
}
return self;
}
- (void)setSelected:(BOOL)selected animated:(BOOL)animated {
[super setSelected:selected animated:animated];
// Configure the view for the selected state
}
#end
// MainViewController.m
-(NSInteger)tableView:(UITableView *)tableView numberOfRowsInSection:(NSInteger)section{
return 1;
}
- (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath
{
static NSString *CellIdentifier = #"Cell";
MTTableViewCell *cell = [tableView dequeueReusableCellWithIdentifier:CellIdentifier];
if (cell == nil) {
cell = [[MTTableViewCell alloc] initWithStyle:UITableViewCellStyleDefault reuseIdentifier:CellIdentifier];
cell.accessoryType = UITableViewCellAccessoryDisclosureIndicator;
}
NSString *namecell = #"namecell";
NSString *statuscell = #"statuscell";
[cell.mainLabel setText:namecell];
[cell.statusLabel setText:statuscell];
return cell;
}
The problem is that nothing is shown when I run the MainViewController. What am I missing? I am not getting any arrors, just an empty tableview with 1 blank record.
Look in your interface builder - you shuld have not "conntected" your custom cell, you should set it as a "files owner" since you implemented the view, not want to set a delegate. Maybe this hint helps?
You are not loading cell from main Bundle :
Use Below code this will work for you :
-(UITableViewCell*)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath{
static NSString *simpleTableIdentifier = #"FleetAccountCell";
FleetAccountCell *cell = [tableView dequeueReusableCellWithIdentifier:simpleTableIdentifier];
if (cell == nil) {
cell = [[[NSBundle mainBundle] loadNibNamed:#"FleetAccountCell" owner:nil options:nil] objectAtIndex: 0];;
}
return cell;
}
Try looking here ... the answer to your problem could be
     
- (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath object:(PFObject *)object{
CustomCell *cell = (CustomCell * )[self.tableView dequeueReusableCellWithIdentifier:#"YOUR CELL NAME" forIndexPath:indexPath];
// your content cell...
return cell;
}
Read it here PFQueryTableViewController not showing custom cells
Greetings :)
This work for me..
-(UITableViewCell*)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath{
static NSString *simpleTableIdentifier = #"cellID";
FleetAccountCell *cell = [tableView dequeueReusableCellWithIdentifier:simpleTableIdentifier];
if (cell == nil) {
cell = [[[NSBundle mainBundle] loadNibNamed:#"Your_nibName" owner:nil options:nil] objectAtIndex: 0];
}
[cell layoutIfNeeded];
return cell;
}
Declare TableViewcell this way :
TableViewCell* cell = [tableView dequeueReusableCellWithIdentifier:#"Cell" forIndexPath:indexPath];
Below one was not working for me :
TableViewCell* cell = [tableView dequeueReusableCellWithIdentifier:#"Cell"];
Rewrite you cellForRowAtIndexPath: method as below
- (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath
{
static NSString *CellIdentifier = #"Cell";
MTTableViewCell *cell = [tableView dequeueReusableCellWithIdentifier:CellIdentifier];
if (cell == nil) {
cell = [[[NSBundle mainBundle] loadNibNamed:#"CUSTOME_CELL_Nib_NAME" owner:nil options:nil] objectAtIndex: 0];;
cell.accessoryType = UITableViewCellAccessoryDisclosureIndicator;
}
NSString *namecell = #"namecell";
NSString *statuscell = #"statuscell";
[cell.mainLabel setText:namecell];
[cell.statusLabel setText:statuscell];
return cell;
}
-(NSInteger)tableView:(UITableView *)tableView numberOfRowsInSection:(NSInteger)section
{
return 4;
}
- (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath
{
static NSString *cellIdentifier = #"cell";
TableViewCell *cell = (TableViewCell *)[self.tableView dequeueReusableCellWithIdentifier:cellIdentifier];
if (cell==nil)
{
NSArray *topLevelObjects = [[NSBundle mainBundle] loadNibNamed:#"TableViewCell" owner:self options:nil];
cell = [topLevelObjects objectAtIndex:0];
}
return cell;
}
- (NSInteger)numberOfSectionsInTableView:(UITableView *)tableView
{
return 1;
}
I had the same problem, I was missing a connection in the tableview delegates and datasource:
self.yourtableviewname.delegate=self;
self.youtableviewname.datasource=self;
After that it worked fine.
Select the cell and in the inspector tab,check mark "installed" and it will work.
You didn't instantiate mainLabel and statusLabel,so they are nil right now.You must instantiate them in the initWithStyle method.

How can i use custom UITableViewCell and UITableView in same xib

I want to use a custom UITableviewCell with UITableView in same xib without creating a UITableViewCell class?
As you can see bellow i set the identifier for UITableViewCell and used it like this:
- (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath
{
static NSString *CellIdentifier = #"CustomIdentifier";
UITableViewCell *cell = [tableView dequeueReusableCellWithIdentifier:CellIdentifier];
if (cell == nil) {
cell = [[UITableViewCell alloc] initWithStyle:UITableViewCellStyleDefault reuseIdentifier:CellIdentifier];
}
}
But Not Working?
Add a UITableViewCell *customCell property to your view controller (for example, your file ShowUsers.h)...
#property (nonatomic, strong) IBOutlet UITableViewCell *customCell;
and connect it to the custom cell in your xib. Then use the following code in cellForRow (for example, your file ShowUsers.m) :
if (cell == nil) {
[[NSBundle mainBundle] loadNibNamed:#"NibName" owner:self options:nil];
cell = self.customCell;
self.customCell = nil;
}
Yes you can do as following code
Under ViewDidLoad or ViewWillAppear
label1Array=[NSMutableArray arrayWithObjects:#"A",#"B",nil];
label2Array=[NSMutableArray arrayWithObjects:#"C",#"D",nil];
label3Array=[NSMutableArray arrayWithObjects:#"E",#"F",nil];
UITableViewDelegate
- (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath
{
static NSString *CellIdentifier = #"aCell";
UITableViewCell *cell = [tableView dequeueReusableCellWithIdentifier:CellIdentifier];
if (cell == nil) {
cell = [[UITableViewCell alloc] initWithStyle:UITableViewCellStyleDefault reuseIdentifier:CellIdentifier];
UILabel *label1=[[UILabel alloc]init];
label1.frame=CGRectMake(0,0,40,40);
label1.text=[label1Array objectAtIndex:indexPath.row];
................
[cell.contentView addSubView: label1];
UILabel *label2=[[UILabel alloc]init];
label2.frame=CGRectMake(50,0,40,40);
label2.text=[label2Array objectAtIndex:indexPath.row];
[cell.contentView addSubView: label2];
UILabel *label3=[[UILabel alloc]init];
label3.frame=CGRectMake(100,0,40,40);
label3.text=[label3Array objectAtIndex:indexPath.row];
[cell.contentView addSubView: label3];
}
Hope this Helps !!!
See..You can do like this. Here you are adding two UITableViewCell in one TableView using XIB.
In Class.h file :-
Declare one mutable array for number of cells.
{
NSMutableArray * sectionRows;
}
#property (nonatomic,retain) IBOutlet UITableViewCell *addTvc1;
#property (nonatomic,retain) IBOutlet UITableViewCell *addTvc2;
In Class.m :-
#synthesize addTvc1, addTvc2;
- (void)viewDidLoad
{
[super viewDidLoad];
sectionRows = [[NSMutableArray alloc] init];
[sectionRows addObject:[[NSMutableArray alloc]
initWithObjects:addTvc1, nil]];
[sectionRows addObject:[[NSMutableArray alloc]
initWithObjects:addTvc2, nil]];
}
In UITableViewDelegate Method -
Add This -
- (NSInteger)numberOfSectionsInTableView:(UITableView *)tableView
{
return [sectionRows count];
}
- (NSInteger)tableView:(UITableView *)tableView numberOfRowsInSection:
(NSInteger)section
{
return [[sectionRows objectAtIndex:section] count];
}
- (UITableViewCell*)tableView:(UITableView *)tableView cellForRowAtIndexPath:
(NSIndexPath *)indexPath
{
return [[sectionRows objectAtIndex:indexPath.section]
objectAtIndex:indexPath.row];
}
Along with code, In Class's XIB drop and drag two UITableViewCell which should be outside from the view and add those cells with Files Owner.
It will work perfectly. Here no need to create one separate custom UITableViewCell class.

Custom UITableCell not working

I searched too much, tried lot of thinks but i couldn't make it work.
I have a view controller, and in that controller i have a tableview which has custom cell.
I connect outlets,datasource and delegate but when i run the project, instead of my custom cells. UITableCell is shown and not showing data either. here is my .h and .m files
#import <UIKit/UIKit.h>
#class SelectMutantCell;
#interface MutantViewController : UIViewController <UITableViewDataSource,UITableViewDelegate>{
UITableView *tableView;
IBOutlet SelectMutantCell *mutantCell;
}
#property (nonatomic, weak) IBOutlet UITableView *tableView;
#property (nonatomic, weak) SelectMutantCell *mutantCell;
- (IBAction)cancel:(id)sender;
#end
and here is my .m file
#implementation MutantViewController
#synthesize tableView = _tableView;
#synthesize mutantCell = _mutantCell;
NSArray *mutants;
- (void)viewDidLoad
{
[super viewDidLoad];
//mutants = [mutants initWithObjects:#"Keko",#"HEHE",#"PEPE", nil];
UINib *cellNib = [UINib nibWithNibName:#"SelectMutantCell" bundle:nil];
[self.tableView registerNib:cellNib forCellReuseIdentifier:#"SelectMutantCell"];
}
- (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath
{
NSString *CellIdentifier = #"SelectMutantCell";
SelectMutantCell *cell = (SelectMutantCell *)[self.tableView dequeueReusableCellWithIdentifier:CellIdentifier];
NSLog(#"---");
cell.nameLabel.text = #"Hehe"];
cell.descriptionLabel.text = #"hhe";
return cell;
}
- (NSInteger)tableView:(UITableView *)tableView numberOfRowsInSection:(NSInteger)section{
return 3;
}
the NSLog(#"---") is for debugging and it appears when running. the problem is in
cell.nameLabel.text = #"Hehe"];
cell.descriptionLabel.text = #"hhe";
this block, if i write cell.textLabel.text = "test" it works but i need my custom cell to shown.
any help will be appreciated..
Insert if(cell==nil){} loop
- (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath
{
NSString *CellIdentifier = #"SelectMutantCell";
SelectMutantCell *cell = (SelectMutantCell *)[self.tableView dequeueReusableCellWithIdentifier:CellIdentifier];
if (cell == nil) {
cell = [[[SelectMutantCell alloc] initWithStyle:UITableViewCellStyleDefault reuseIdentifier:CellIdentifier] autorelease];
}
NSLog(#"---");
cell.nameLabel.text = #"Hehe"];
cell.descriptionLabel.text = #"hhe";
return cell;
}
Looking at your cellForRowAtIndexPath: method, you never initialize the cell. Try doing it like this:
- (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath
{
NSString *CellIdentifier = #"SelectMutantCell";
SelectMutantCell *cell = (SelectMutantCell *)[self.tableView dequeueReusableCellWithIdentifier:CellIdentifier];
if (cell == nil) {
NSArray *topLevelObjects = [[NSBundle mainBundle] loadNibNamed:#"SelectMutantCell" owner:nil options:nil];
for(id currentObject in topLevelObjects) {
if([currentObject isKindOfClass:[SelectMutantCell class]]) {
cell = (SelectMutantCell *)currentObject;
break;
}
}
}
NSLog(#"---");
cell.nameLabel.text = #"Hehe"];
cell.descriptionLabel.text = #"hhe";
return cell;
}
I had the same issue. To solve it check the followings :
in your nib file, you have removed the root view created by default, and dragged a UITableViewCell from XCode object browser, then set the custom type of the UItableViewCell to your subclass SelectMutantCell
you have linked the outlets
you have added the cell identifier to SelectMutantCell, as you would do in storyboard
last but not least, you didn't add the same cell in your storyboard TableView, it will conflit between the one from storyboard and the one from [self.tableView registerNib:cellNib forCellReuseIdentifier:#"SelectMutantCell"];
