Delete UITableViewCell and ALL of that cell"s data



I have a UITableViewCell. I can add and subtract 1 from the cell's textLabel and I can also delete the cells. Here is my problem, Lets say i add 5 to the value of the textLabel . And this cell is at the 0 indexPath (The First cell in the table). When I delete this cell and there are now no longer any cells on the table, I add a new cell and this new cell automatically gets the same value as the cell that was just deleted. SO this new cell will have a value of 5 and i want the cell to have a value of 1 just like every cell should when it is added. This only happens when a cell is deleted and a new cell is added at that exact same indexPath. So my question is: do i have to delete this cells "memory" or "data" for this to be fixed? Thanks a bunch for the help!





CellForRowAtIndexPath :







- (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath: (NSIndexPath *)indexPath

{

static NSString *CellIdentifier = @"Cell";



cell = [tableView dequeueReusableCellWithIdentifier:CellIdentifier];

if (cell == nil)

{

cell = [[UITableViewCell alloc] initWithStyle:UITableViewCellStyleDefault reuseIdentifier:CellIdentifier];

addBtn = [[UIButton alloc]init];

addBtn =[UIButton buttonWithType:UIButtonTypeRoundedRect];

[addBtn setFrame:CGRectMake(220,10,25,55)];

[addBtn addTarget:self action:@selector(addLabelText:) forControlEvents:UIControlEventTouchUpInside];

[addBtn setTitle:@"+" forState:UIControlStateNormal];

[addBtn setEnabled:YES];

[cell addSubview:addBtn];



subBtn = [[UIButton alloc]init];

subBtn=[UIButton buttonWithType:UIButtonTypeRoundedRect];

[subBtn setFrame:CGRectMake(260,10,25,55)];

[subBtn addTarget:self action:@selector(subtractLabelText:) forControlEvents:UIControlEventTouchUpInside];

[subBtn setTitle:@"-" forState:UIControlStateNormal];

[subBtn setEnabled:YES];

[cell addSubview:subBtn];



//cell.textLabel.text = @"1";





}

//cellText.hidden=!self.editing;

[cell setSelectionStyle:UITableViewCellSelectionStyleNone];

cell.imageView.image = [imageArray objectAtIndex:indexPath.row];

cell.textLabel.text = [number objectAtIndex:indexPath.row];





return cell;

}

  1. When cells are deleted or go off screen, the table view saves them and reuses them later. So you need to reset textLabel's value in tableView:cellForRowAtIndexPath:. The UITableViewCell class reference says this:


    The table view's delegate in tableView:cellForRowAtIndexPath: should always reset all content when reusing a cell.

Slow Android emulator

I have a 2.67 GHz Celeron processor, 1.21 GB of RAM on a x86 Windows XP Professional machine. My understanding is that the Android emulator should start fairly quickly on such a machine, but for me it does not. I have followed all instructions in setting up the IDE, SDKs, JDKs and such and have had some success in staring the emulator quickly but is very particulary. How can I, if possible, fix this problem?

Java Urban Myths

Along the line of C++ Urban Myths and Perl Myths : What are the Java Urban Myths? That is, the ideas and conceptions about Java that are common but have no actual roots in reality . As a Java programmer, what ideas held by your fellow Java programmers have you had to disprove so often that you've come to believe they all learned at the feet of the same drunk old story-teller? Ideally, you would express these myths in a single sentence, and include an explanation of why they are false.
