[UITableViewCell menuImage]: unrecognized selector sent to instance 0x10bb1e5e0 - ios

I created a separate UITableViewCell and designed it using .xib file and it looks like
My header file for UITableViewCell looks like
#interface MenuTableViewCell : UITableViewCell
#property(nonatomic, weak) IBOutlet UIImageView *menuImage;
#property(nonatomic, weak) IBOutlet UILabel *menuLabel;
#end
and both properties are connected
I tried to use it in my MenuViewController as
- (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath {
MenuTableViewCell *cell = [tableView dequeueReusableCellWithIdentifier:CellIdentifier forIndexPath:indexPath];
cell.menuImage.image = [self getImageNameForRow:indexPath.row];
cell.menuLabel.text = self.features[(NSUInteger) indexPath.row];
return cell;
}
and
- (UIImage *)getImageNameForRow:(NSInteger)row {
if (row == 0) {
return [UIImage imageNamed:#"Transaction"];
}
if (row == 1) {
return [UIImage imageNamed:#"Summary"];
}
return [UIImage imageNamed:#"Budget"];
}
when I run my application, it crashes and shows the following on log

I am very new to iOS and can't understand the error message, can some one please help me knowing what am In doing wrong?

There were 2 problems.
I was registering UITableViewCell instead of MenuTableViewCell
I was not registering the nib file I had
After making the change as following things, started to work again.
[self.tableView registerNib:[UINib nibWithNibName:#"MenuTableViewCell" bundle:nil] forCellReuseIdentifier:CellIdentifier];
Thank you for all your answers, they helped me a lot!

Declare an imgearray in interface,then add your array of images,next cellforatindexpath add code for UIImageView
yourcellname.yourimagename.image=[UIImage imagenamed:[yourimagearray objectAtIndexPath.row]];

TableView in a tableView chrashes

I have a static UItableView. In one of the cells, I have a dynamic prototype UITableView. Here is the code I implemented:
In viewDidLoad:
self.tagsArray = [[NSArray alloc] initWithObjects:#"hey", #"what", #"ola", #"dada", #"hoster", #"umi", nil];
- (NSInteger)numberOfSectionsInTableView:(UITableView *)tableView {
return self.tableView == tableView ? 2 : 1;
}
- (NSInteger)tableView:(UITableView *)tableView numberOfRowsInSection:(NSInteger)section {
if (self.tableView == tableView)
return (section == 0) ? 3 : 2;
else
return [self.tagsArray count];
}
- (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath
{
UITableViewCell *cell;
if (self.tableView == tableView) {
cell = [super tableView:tableView cellForRowAtIndexPath:indexPath];
}
else {
cell = [tableView dequeueReusableCellWithIdentifier:#"cell" forIndexPath:indexPath];
[cell.textLabel setText:self.tagsArray [indexPath.row]];
}
return cell;
}
When I run the app, everything works fine. But when I start scrolling on the inner tableView (the dynamic prototype one), then I get the following error:
Terminating app due to uncaught exception 'NSRangeException', reason: '*** -[__NSArrayI objectAtIndex:]: index 3 beyond bounds [0 .. 2]'

libc++abi.dylib: terminating with uncaught exception of type NSException
I don't know what the above error means, but I think that it's not creating new cells for some reason, and because of that, it has a conflict with the number of cells to display, so it crashes with the above error.
Why isn't the inner tableView creating new cells, and what can I do to fix it?
What the error is telling you is that you tried to access an element that doesn't exist.
Your data array only has 2 elements, but you are hardcoding the amount of cells you want to create (3) so when it looks for the 3rd element to create the cell it crashes because is not existent.

uncaught exception 'NSInvalidArgumentException' error during runtime

my code is:
- (void) tableView:(UITableView *)tableView
commitEditingStyle:(UITableViewCellEditingStyle)editingStyle
forRowAtIndexPath:(NSIndexPath *)indexPath{
if (editingStyle == UITableViewCellEditingStyleDelete){
/* First remove this object from the source */
[self.allRows removeObjectAtIndex:indexPath.row];
/* Then remove the associated cell from the Table View */
[tableView deleteRowsAtIndexPaths:#[indexPath]
withRowAnimation:UITableViewRowAnimationFade];
}
}
i am getting error as follows

I think your TableView may be getting released after you create it and the method ends. You probably need to create an instance variable inside in View controller that references it.
#property (strong, nonatomic) IBOutlet UITableView *tablview;
Then remove the associated cell from the Table View
[self.tablview deleteRowsAtIndexPaths:#[indexPath]
withRowAnimation:UITableViewRowAnimationFade];
May help you..
Try this
-(void)tableView:(UITableView *)tableView commitEditingStyle:(UITableViewCellEditingStyle)editingStyle forRowAtIndexPath:(NSIndexPath *)indexPath
{
//remove the row from data model
[tableData removeObjectAtIndex:indexPath.row];
[tableView deleteRowsAtIndexPaths:#[indexPath] withRowAnimation:UITableViewRowAnimationAutomatic];
}

Localized App crashes with NSRangeException

I have an iOS app that has been working quite well in two languages – I know added some stuff, already keeping in mind using NSLocalizedString for localization etc. The english version of the app works fine so far, but the second language version crashes right after starting. Why?
One should note that I have not added all NSLocalizedStrings in my localizable.strings file. Furthermore, I have two separate Storyboards for both english an german. Any help would be greatly appreciated!

EDIT
- (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.textLabel.text = #"Error";
if (indexPath.section == 0) {
if(indexPath.row == 0)
{ /*..*/}
}
return cell;
}
Turns out I needed to implement indentationLevelForRowAtIndexPath and just return 0.

Strange SIGABRT crash after all cells are returned

I've been trying to solve this problem for the past two days but I just can't find why it occurs, so I took it here to ask if you guys have any idea about it.
So I have a UITableView which I display some items in. I also have a UITableViewCell which I use as the cells.
I register the nib with my table view in the viewDidLoad:
[self.QuickPickDetailsTV registerNib:[UINib nibWithNibName:#"QuickPickItemCell"
bundle:[NSBundle mainBundle]]
forCellReuseIdentifier:#"QuickPickItemCellReuseID"];
Then in the tableView:cellForRowAtIndexPath:, I reuse, populate, and return the cell as below:
static NSString *CellIdentifier = #"QuickPickItemCellReuseID";
QuickPickItemCell *cell = [tableView dequeueReusableCellWithIdentifier:CellIdentifier];
if (cell == nil) {
cell = [[QuickPickItemCell alloc] initWithStyle:UITableViewCellStyleDefault reuseIdentifier:CellIdentifier];
cell.selectionStyle = UITableViewCellSelectionStyleNone;
}
NSDictionary *quickPickItem = [self.myQuickPickItems objectAtIndex:indexPath.row];
NSString *theQuickPickItemName = [quickPickItem valueForKey:#"name"];
[cell.mName setFont:[UIFont fontWithName:#"OpenSans" size:16]];
[cell.mName setText:NSLocalizedString(theQuickPickItemName, nil)];
return cell;
The method above gets called for the number of items it should display (as expected), and crashes with an strange error after the last cell is returned:

I have searched all my code but I don't send length to any object in my code. I don't know where is the crash coming from since it is shown to be on my main.m.
I have tried turning on NSZombies as well, but I didn't get any warnings about released objects.
Any help will be appreciated!
Thanks

libc++abi.dylib: terminating with uncaught exception of type NSException
And the property in question is
#property(strong,nonatomic) NSURL *imageURL;
with setter
-(void)setImageURL:(NSURL *)imageURL
{
_imageURL=imageURL;
[self startDownloadingImage];
}
The strange thing is this used to work and about an hour or so ago it stops working and starts throwing this exception.
update
- (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath
{
BCDDogImageTableViewCell *cell = [tableView dequeueReusableCellWithIdentifier:[BCDDogImageTableViewCell cellPrototypeIdentifier] forIndexPath:indexPath];
NSLog(#"THE CELL IS: %# ", cell);
cell.imageURL=[NSURL URLWithString:self.imageURLs[indexPath.row]];
return cell;
}
The error is because your cell is actually a UITableViewCell instance and not an instance of your custom cell class.
Be sure to register your custom cell class for the cell.
