I have a view-based app that just does one thing : show a array in a TableView, but it doesn't work and I don't know why. Here's the code.
.h
@interface ViewController : UIViewController <UITableViewDelegate, UITableViewDataSource>{
NSArray *array;
IBOutlet UITableView *table;
}
.m
-(void)viewDidLoad{
[super viewDidLoad];
array = [array initWithObjects:@"iPad", @"iTV", nil];
}
- (NSInteger)numberOfSectionsInTableView:(UITableView *)tableView
{
return 1;
}
- (NSInteger)tableView:(UITableView *)tableView numberOfRowsInSection:(NSInteger)section
{
return [array count];
}
- (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 = [array objectAtIndex:indexPath.row];
return cell;
}
Any ideas why the TableView doesn't show the text? Thank you people!
array = [array initWithObjects:@"iPad", @"iTV", nil];
ReplyDeleteShould be
array = [NSArray initWithObjects:@"iPad", @"iTV", nil];
also make sure you call arrayInit as barley mentioned
edit:
Vince is right in pointing out it should either be
[[NSArray alloc] initWithObjects:@"iPad", @"iTV", nil];
or
[NSArray arrayWithObjects:@"iPad",@"iTV",nil];
depending on if you want to retain or have it auto released
Ill assume you are running under ARC
ReplyDeleteNSIndexPath doesn't have a "row" property try
NSInteger row = [indexPath indexAtPosition:1];
cell.textLabel.text = [array objectAtIndex:row];
