Is it possible to have two different UiTableViewCells in one UiTableView? [duplicate] - ios

Question

This question already has answers here:
2 different types of custom UITableViewCells in UITableView
(3 answers)
Closed 9 years ago.
I'm having an issue and would like to know if what I am trying to do is even possible.
I have a ViewController that has a UITableView as a subview. I then loaded a custom cell and it worked fine. However, I needed another custom cell in the same tableview - this second cell has a separate nib as well.
Is this possible?
Two different custom cells in on section in a UITableView?
I did try something like this:
- (UITableViewCell*)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath
{
static NSString *CellIdentifier1 = #"ContentCell";
static NSString *CellIdentifier2 = #"SpaceCell";
// Space Cell
if (indexPath.row== 0) {
CellSpace *cell = (CellSpace *) [tableViewdequeueReusableCellWithIdentifier:CellIdentifier2];
return cell;
}
// Content cell
else {
CellView *cell = (CellView *)[tableView dequeueReusableCellWithIdentifier:CellIdentifier1];
// Configure cell
return cell;
}
}
However it seems the else statement is never fired and I normally get a crash saying the method returned nil.
UPDATE
I used the advice and code here and came up with this:
#pragma mark - UITableView Delegate Methods
-(CGFloat)tableView:(UITableView *)tableView heightForRowAtIndexPath:(NSIndexPath *)indexPath
{
return 160;
}
-(NSInteger)tableView:(UITableView *)tableView numberOfRowsInSection:(NSInteger)section
{
return 22;
}
-(NSInteger)numberOfSectionsInTableView:(UITableView *)tableView
{
return 1;
}
-(UITableViewCell *) tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath{
static NSString *CellIdentifier1 = #"UsernameCell";
static NSString *CellIdentifier2 = #"PasswordCell";
if(indexPath.row == 0) {
BBUsernameRegistrationCell *cell = (BBUsernameRegistrationCell *)[tableView dequeueReusableCellWithIdentifier:CellIdentifier1];
if(cell == nil) {
NSArray *nib = [[NSBundle mainBundle] loadNibNamed:CellIdentifier1 owner:self options:nil]; // set properties
cell = nib[0];
}
// set properties
return cell;
}
// Content cell
else {
BBPasswordTableViewCell *cell = (BBPasswordTableViewCell *)[tableView dequeueReusableCellWithIdentifier:CellIdentifier2];
if(cell == nil) {
NSArray *nib = [[NSBundle mainBundle] loadNibNamed:CellIdentifier2 owner:self options:nil]; // set properties
cell = nib[0];
}
// set properties
return cell;
}
}
However I only see the first Cell in my tableview. If I switch the cells around the second one loads. But not both at the same time. Does anyone have any idea why?

Yes, it is possible..
- (UITableViewCell*)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath
{
static NSString *CellIdentifier1 = #"ContentCell";
static NSString *CellIdentifier2 = #"SpaceCell";
// Space Cell
if (indexPath.row== 0) {
CellSpace *cell = (CellSpace *)[tableView dequeueReusableCellWithIdentifier:CellIdentifier2];
if(cell == nil) {
cell = [[CellSpace alloc] initWithStyle:UITableViewCellStyleDefault reuseIdentifier:CellIdentifier1];
// set properties
}
// set properties
return cell;
}
// Content cell
else {
CellView *cell = (CellView *)[tableView dequeueReusableCellWithIdentifier:CellIdentifier2];
if(cell == nil) {
cell = [[CellView alloc] initWithStyle:UITableViewCellStyleDefault reuseIdentifier:CellIdentifier2];
// set properties
}
// set properties
return cell;
}
}
in your custom cell, do something like this in initWithStyle method:
- (id)initWithStyle:(UITableViewCellStyle)style reuseIdentifier:(NSString *)reuseIdentifier
{
NSArray *topLevelObjects = [[NSBundle mainBundle] loadNibNamed:#"CellView" owner:self options:nil];
for (id currentObj in topLevelObjects ) {
if ([currentObj isKindOfClass:[CellView class]]) {
self = (CellView*) currentObj;
}
}
return self;
}

Yes it is possible. But before use this dequeueReusableCellWithIdentifier:. Just register your cell and corresponding nib files.
code as..
-(void)initiateCellRegisteration
{
static NSString *CellIdentifier1 = #"ContentCell";
static NSString *CellIdentifier2 = #"SpaceCell";
[self.tableView registerClass:[ContentCell class] forCellReuseIdentifier:CellIdentifier2];
[self.tableView registerNib:[UINib nibWithNibName:CellIdentifier2 bundle:nil] forCellReuseIdentifier:CellIdentifier2];
[self.tableView registerClass:[SpaceCell class] forCellReuseIdentifier:CellIdentifier1];
[self.tableView registerNib:[UINib nibWithNibName:CellIdentifier1 bundle:nil] forCellReuseIdentifier:CellIdentifier1];
}
Call this method in viewDidLoad

If you are using the cell nib then you need little tricky way to get your cell nib like
static NSString *CellIdentifier = #"ProductCell";
IVProductCell *cell = (IVProductCell*)[tableView dequeueReusableCellWithIdentifier:CellIdentifier];
if (cell == nil) {
NSArray* objects = [[NSBundle mainBundle] loadNibNamed:#"IVProductCell" owner:nil options:nil];
for (id currentObject in objects) {
if ([currentObject isKindOfClass:[IVProductCell class]]){
cell = (IVProductCell*) currentObject;
}
}
}
