I am trying to create a custom cell for my UITableView. I am using Xcode 4.2 and using the storyboard along with ARC.
I have created a class to represent the custom cell like so:
ResultsCustomCell.h
#import <UIKit/UIKit.h>
@interface ResultsCustomCell : UITableViewCell
{
IBOutlet UILabel *customLabel;
}
@property (nonatomic, retain) IBOutlet UILabel* customLabel;
@end
ResultsCustomCell.m
#import "ResultsCustomCell.h"
@implementation ResultsCustomCell
@synthesize customLabel;
@end
I have then implemented the UITableView method in my view controller as follows: ViewController.m
#import "ViewController.h"
#import "ResultsCustomCell.h"
@implementation ViewController
- (void)didReceiveMemoryWarning
{
[super didReceiveMemoryWarning];
// Release any cached data, images, etc that aren't in use.
}
#pragma mark - View lifecycle
- (void)viewDidLoad
{
[super viewDidLoad];
}
// Set the number of items in the tableview to match the array count
-(NSInteger)tableView:(UITableView *)tableView numberOfRowsInSection:(NSInteger)section
{
return 5;
}
// Populate TableView cells with contents of array.
-(UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath
{
static NSString *CellIdentifier = @"CellIdentifier";
ResultsCustomCell *myCell = [tableView dequeueReusableCellWithIdentifier:@"CellIdentifier"];
myCell.customLabel.text = @"helloWorld";
return myCell;
}
// Define height for cell.
-(CGFloat)tableView:(UITableView *)tableView heightForRowAtIndexPath:(NSIndexPath *)indexPath
{
return 80;
}
@end
The application builds successfully but then crashes instantly and give me the following error:
Terminating app due to uncaught exception 'NSInternalInconsistencyException', reason: 'UITableView dataSource must return a cell from tableView:cellForRowAtIndexPath:'
What part am I missing out?
I'm not entirely sure what I have done to resolve my problem but It is now working correctly.
Here is what I currently have in my ViewController.m
Note: The ResultsCustomCell.h and .m are the same as above.
#import "ViewController.h"
#import "ResultsCustomCell.h"
@implementation ViewController
- (void)didReceiveMemoryWarning
{
[super didReceiveMemoryWarning];
// Release any cached data, images, etc that aren't in use.
}
#pragma mark - View lifecycle
- (void)viewDidLoad
{
[super viewDidLoad];
}
// Set the number of items in the tableview to match the array count
-(NSInteger)tableView:(UITableView *)tableView numberOfRowsInSection:(NSInteger)section
{
return 5;
}
// Populate TableView cells with contents of array.
-(UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath
{
static NSString *CellIdentifier = @"CellIdentifier";
// Make sure there are no quotations (") around the cell Identifier.
ResultsCustomCell *myCell = [tableView dequeueReusableCellWithIdentifier:CellIdentifier];
myCell.customLabel.text = @"helloWorld";
return myCell;
}
// Define height for cell.
-(CGFloat)tableView:(UITableView *)tableView heightForRowAtIndexPath:(NSIndexPath *)indexPath
{
return 80;
}
@end
I then made sure the following things where correct:
After using this code and checking all of the above it appears to work.
