Fill UITableCellView with a uibutton - uitableview

Question

My goal is insert in a cell of grouped tableview a button that is perfectly fill it, like facebook or skype login on iPad. To do this I use this code:
- (UITableViewCell *)tableView:(UITableView *)aTableView cellForRowAtIndexPath:(NSIndexPath *)indexPath{
static NSString *CellIdentifier = #"Login";
UITableViewCell* cell = [aTableView dequeueReusableCellWithIdentifier:CellIdentifier];
if(cell == nil){
cell = [[[UITableViewCell alloc] initWithStyle:UITableViewCellStyleDefault reuseIdentifier:CellIdentifier] autorelease];
}
if(indexPath.section == 1 && indexPath.row == 0){
UIButton *button = [UIButton buttonWithType:UIButtonTypeRoundedRect];
[button setFrame:cell.frame];
[button setTitle:#"Do Stuff" forState:UIControlStateNormal];
[cell addSubview:button];
}
return cell;
}
But the result is this:
is not what i wanted, the button is wider than cell and its position is incorrect.
I solved doing various tests to find the right values ​​for the frame of the button, but I think this is not the best and most elegant solution. Does anyone have a better solution than mine?
Instead with this code:
if(indexPath.section == 1 && indexPath.row == 0){
UIButton *button = [UIButton buttonWithType:UIButtonTypeRoundedRect];
[button setFrame:cell.bounds];//note here bounds
[button setTitle:#"Do Stuff" forState:UIControlStateNormal];
[cell.contentView addSubview:button];
}
return cell;
the result is:

Answer 1

Here is the correct answer. The key is to set the autoresizingMask as shown in following code sample.
- (UITableViewCell *)tableView:(UITableView *)aTableView cellForRowAtIndexPath:(NSIndexPath *)indexPath {
NSString* CellIdentifier = nil;
if (indexPath.section == BTNSCTN && indexPath.row == BTNROW) {
CellIdentifier = #"ButtonCell";
UITableViewCell* cell = (UITableViewCell*)[tableView dequeueReusableCellWithIdentifier:CellIdentifier];
if (!cell) {
cell = [[UITableViewCell alloc]
initWithStyle:UITableViewCellStyleDefault
reuseIdentifier:CellIdentifier]; // autorelease if not using ARC
UIButton* buttonUp = [UIButton buttonWithType:UIButtonTypeRoundedRect];
[buttonUp setTitle:#"Shake it up!" forState:UIControlStateNormal];
[buttonUp addTarget:self action:#selector(shakePhone)
forControlEvents:UIControlEventTouchUpInside];
buttonUp.frame = cell.contentView.bounds; // or cell.bounds
buttonUp.autoresizingMask =
UIViewAutoresizingFlexibleWidth | UIViewAutoresizingFlexibleHeight;
[cell.contentView addSubview:buttonUp];
}
return cell;
}
else
// handle the other sections and cells...

- (UITableViewCell *)tableView:(UITableView *)aTableView cellForRowAtIndexPath:(NSIndexPath *)indexPath{
static NSString *CellIdentifier = #"Login";
UITableViewCell* cell = [aTableView dequeueReusableCellWithIdentifier:CellIdentifier];
if(cell == nil){
cell = [[[UITableViewCell alloc] initWithStyle:UITableViewCellStyleDefault reuseIdentifier:CellIdentifier] autorelease];
if(indexPath.section == 1 && indexPath.row == 0){
UIButton *button = [UIButton buttonWithType:UIButtonTypeCustom];//note here
[button setFrame:cell.bounds];//note here bounds
[button setTitle:#"Do Stuff" forState:UIControlStateNormal];
cell.clipsToBounds=YES;//note here
[cell.contentView addSubview:button];//note here contentview
}
}
return cell;
