UITableView madness
- by kesrut
Hello,
I'm new to iPhone application development. I'm trying to understand how to use UITableView.
I'm wrote simple code:
- (NSInteger)numberOfSectionsInTableView:(UITableView *)tableView {
return 1;
}
- (NSInteger)tableView:(UITableView *)tableView numberOfRowsInSection:(NSInteger)section {
return 1 ;
}
- (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath {
static NSString *MyIdentifier = @"MyIdentifier";
UITableViewCell *cell = [tableView dequeueReusableCellWithIdentifier:MyIdentifier];
if (cell == nil) {
cell = [[[UITableViewCell alloc] initWithStyle:UITableViewCellStyleDefault reuseIdentifier:MyIdentifier] autorelease];
}
cell.textLabel.text = @"Hello";
return cell;
}
UITable shows content, but if i'm drag table contents my application terminates. You can see video: http://www.youtube.com/watch?v=TucTVJVhSD0
I tried to everything with array:
- (NSInteger)numberOfSectionsInTableView:(UITableView *)tableView {
return 1 ;
}
- (NSInteger)tableView:(UITableView *)tableView numberOfRowsInSection:(NSInteger)section {
return [hello count] ;
}
- (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath {
static NSString *MyIdentifier = @"MyIdentifier";
UITableViewCell *cell = [tableView dequeueReusableCellWithIdentifier:MyIdentifier];
if (cell == nil) {
cell = [[[UITableViewCell alloc] initWithStyle:UITableViewCellStyleDefault reuseIdentifier:MyIdentifier] autorelease];
}
cell.textLabel.text = [hello objectAtIndex:indexPath.row];
return cell;
}
- (void)tableView:(UITableView *)tableView didSelectRowAtIndexPath:(NSIndexPath *)indexPath
{
[tableView deselectRowAtIndexPath:indexPath animated:NO];
NSLog(@"Selected") ;
}
- (void) awakeFromNib
{
hello = [[NSArray alloc] initWithObjects:@"hello", @"world", @"end", nil];
}
// Implement viewDidLoad to do additional setup after loading the view, typically from a nib.
- (void)viewDidLoad {
[super viewDidLoad];
}
Content is shown and if I'm selecting item i'm getting: [Session started at 2010-03-16 19:21:48 +0200.]
2010-03-16 19:21:52.295 ViewTest[1775:207] * -[ViewTestViewController respondsToSelector:]: message sent to deallocated instance 0x3911ec0
I'm total new to iPhone programming. And as i see everything i do - i'm just getting application terminated ..
