UITableViewCell shifts the content when reloaded - iphone

I am using a custom UITableViewCell with a UILabel at the top ,a UIButton just below the label and another UILabel,just under this button.
Final UILabel will be hidden initially,and will be opened when button action is called.The height of all the label and the cell are dynamic.
But
When i select the button ,the cell shifts its contentview to the.
center
I need the content of the cells to start at the origin itself.
- (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath {
static NSString *CellIdentifier = #"ReferenceCell";
ReferenceiPadTableCell *cell = (ReferenceiPadTableCell *)[tableView dequeueReusableCellWithIdentifier:CellIdentifier];
if (cell == nil) {
NSArray *nib = [[NSBundle mainBundle] loadNibNamed:#"ReferenceiPadTableCell" owner:self options:Nil];
cell = [nib objectAtIndex:0];
cell.accessoryView = nil;
}
tableView.separatorStyle = UITableViewCellSeparatorStyleNone;
NSDictionary *referenceDictionary = [self.referencesList objectAtIndex:indexPath.row];
NSString *nameString = [referenceDictionary objectForKey:#"name"];
CGSize labelSize = [nameString sizeWithFont:[UIFont systemFontOfSize:14]
constrainedToSize:CGSizeMake(listTableView.frame.size.width - 15, 125)
lineBreakMode:UILineBreakModeWordWrap];
labelSize.height = labelSize.height > 96? labelSize.height : 96;
cell.l1.text = nameString;
cell.l1.frame = CGRectMake(cell.l1.frame.origin.x, 6, cell.l1.frame.size.width, labelSize.height);
cell.button.tag = [[referenceDictionary objectForKey:#"sort"] intValue];
[cell.button addTarget:self action:#selector(showList:) forControlEvents:UIControlEventTouchUpInside];
cell.l2.hidden = YES;
cell.button.frame = CGRectMake(cell.button.frame.origin.x, cell.l1.frame.origin.y+ labelSize.height + 1, cell.l1.frame.size.width, cell.l1.frame.size.height);
if ([self.showList objectForKey:[NSString stringWithFormat:#"showList-%d", indexPath.row]] )
{
cell.l2.hidden = NO;
NSDictionary *dic = [self.abstractList objectAtIndex:indexPath.row];
NSString *abtString = [dic objectForKey:#"name"];
CGSize absSize = [abtString sizeWithFont:[UIFont systemFontOfSize:14]
constrainedToSize:CGSizeMake(tableView.frame.size.width - 15, 125)
lineBreakMode:UILineBreakModeWordWrap];
cell.l2.frame = CGRectMake(cell.button.frame.origin.x, cell.button.frame.origin.y+ cell.button.frame.size.height + 3, cell.button.frame.size.width, absSize.height);
cell.l2.text = abtString;
}
return cell;
}

it's doesn't shift the content but added more subview on UITableViewCell because you are not using reusing cell concept well.So use concept like this
-(UITableViewCell *)tableView:(UITableView *)tableView reuseTableViewCellWithIdentifier:(NSString *)identifier withIndexPath:(NSIndexPath *) indexPath
{
UITableViewCell *cell=[[UITableViewCell alloc] initWithStyle:UITableViewCellStyleDefault reuseIdentifier:identifier];
UILabel *lbl=[[UILabel alloc]init];
lbl.lineBreakMode = NSLineBreakByWordWrapping;
lbl.numberOfLines = 0;
lbl.backgroundColor=[UIColor clearColor];
lbl.textAlignment=NSTextAlignmentCenter;
UIImageView *imgView=[[UIImageView alloc]init];
UIImageView *imgView1=[[UIImageView alloc]init];
UIImageView *imgView2=[[UIImageView alloc]init];
UIImageView *imgView3=[[UIImageView alloc]init];
UIImageView *imgView4=[[UIImageView alloc]init];
if(UI_USER_INTERFACE_IDIOM()==UIUserInterfaceIdiomPhone)
{
lbl.font=[UIFont fontWithName:#"Marker Felt" size:20];
}
else
{
lbl.font=[UIFont fontWithName:#"Marker Felt" size:30];
}
[cell.contentView addSubview:lbl];
[cell.contentView addSubview:imgView];
[cell.contentView addSubview:imgView1];
[cell.contentView addSubview:imgView2];
[cell.contentView addSubview:imgView3];
[cell.contentView addSubview:imgView4];
return cell;
}
-(UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath
{
static NSString *CellIdentifier = #"Cell";
UITableViewCell *cell = [tableView dequeueReusableCellWithIdentifier:CellIdentifier];
if (cell == nil) {
cell=[self tableView:tableView reuseTableViewCellWithIdentifier:CellIdentifier withIndexPath:indexPath];
if ([[UIDevice currentDevice] userInterfaceIdiom] == UIUserInterfaceIdiomPhone) {
}
}
}

Load more at the top of uitableview

I need a load more cell at the top of my table populated with custom cell, the first time that I populate the table is all ok, no overlap and no problem, if I try to load more cell this cell appear but with the wrong height and if I try to scroll the cell change position randomly!
This is my code, where the mistake for you?
- (NSInteger) tableView:(UITableView *)tableView numberOfRowsInSection:(NSInteger)section {
return [self.arrayMessaggi count] + 1;
}
- (UITableViewCell *) tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath {
static NSString *CellIdentifier = #"Cell";
UITableViewCell *cell = [tableView dequeueReusableCellWithIdentifier:CellIdentifier];
if (indexPath.row == 0) {
if (cell == nil) {
cell = [[UITableViewCell alloc] initWithStyle:UITableViewCellStyleDefault reuseIdentifier:CellIdentifier];
UILabel *labelLoad = [[UILabel alloc] initWithFrame:CGRectMake(0, 0, 320, 44)];
[labelLoad setBackgroundColor:[UIColor clearColor]];
[labelLoad setTextAlignment:NSTextAlignmentCenter];
[labelLoad setText:[NSString stringWithFormat:#"%d - Load more...",indexPath.row]];
[labelLoad setText:#"Load more..."];
[labelLoad setTag:3];
[cell.contentView addSubview:labelLoad];
}
UILabel *labelLoad = (UILabel *)[cell.contentView viewWithTag:3];
[labelLoad setText:[NSString stringWithFormat:#"%d - Load more...",indexPath.row]];
}
else {
if (cell == nil) {
cell = [[UITableViewCell alloc] initWithStyle:UITableViewCellStyleDefault reuseIdentifier:CellIdentifier];
PFObject *obj = [self.arrayMessaggi objectAtIndex:indexPath.row - 1];
PFUser *user = [obj objectForKey:#"daUtente"];
float height = [self getStringHeight:[obj objectForKey:#"TestoMessaggio"] andFont:[UIFont systemFontOfSize:13]];
UILabel *labelUser = [[UILabel alloc] initWithFrame:CGRectMake(20, 10, 280, 20)];
[labelUser setBackgroundColor:[UIColor clearColor]];
[labelUser setText:[user objectForKey:#"username"]];
[labelUser setFont:[UIFont systemFontOfSize:13]];
[labelUser setTag:1];
[cell.contentView addSubview:labelUser];
}

PFUser *user = [obj objectForKey:#"daUtente"];
UILabel *labelUser = (UILabel *)[cell.contentView viewWithTag:1];
[labelUser setText:[NSString stringWithFormat:#"%d - %#",indexPath.row,[user objectForKey:#"username"]]];
}
return cell;
}
- (CGFloat)tableView:(UITableView *)tableView heightForRowAtIndexPath:(NSIndexPath *)indexPath {
float height = 44;
if (indexPath.row > 0) {
PFObject *obj = [self.arrayMessaggi objectAtIndex:indexPath.row - 1];
NSString *text = [obj objectForKey:#"TestoMessaggio"];
height = 30 + [self getStringHeight:text andFont:[UIFont systemFontOfSize:13]] + 10;
}
return height;
}

UILabel does not disappear in UItableView

-(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];

}
return cell;
}
I have added a label in each row which displays number of messages received.In didSelect method i make label count zero so i can disappear label from tableView.In case of more than one row in table view label not disappear.
The simple and dirty method to reach what u want is to use a tag
-(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];
}
NSArray *seperateArray = [[clist objectForKey:[[clist allKeys]objectAtIndex:indexPath.row]]componentsSeparatedByString:#"#"];
cell.accessoryType = UITableViewCellAccessoryDisclosureIndicator;
cell.textLabel.text = [seperateArray objectAtIndex:0];
cell.selectionStyle = UITableViewCellSelectionStyleNone;
if (![[seperateArray objectAtIndex:1] isEqualToString:#"0"]) {
lblCnt = [[UILabel alloc]initWithFrame:CGRectMake(260, 13, 20, 20)];
lblCnt.backgroundColor = [UIColor lightGrayColor];
lblCnt.textColor = [UIColor blackColor];
lblCnt.text = [seperateArray objectAtIndex:1];
lblCnt.textAlignment = UITextAlignmentCenter;
lblCnt.layer.masksToBounds = YES;
lblCnt.layer.cornerRadius = 2.0f;
[cell.contentView addSubview:lblCnt];
//Add a tag
lblCnt.tag = 1000;
}
else
{
/*
NSLog(#"msgCount1 %#\n",[seperateArray objectAtIndex:1]);
[lblCnt removeFromSuperview];
lblCnt.hidden = YES;
*/
for (UIView *view in [cell.contentView subviews]) {
if (view.tag == 1000) {
[view removeFromSuperview];
}
}
}
return cell;
}
and select the view based on the tag.

How to show buttons in uitableview cell and their action will be shown on label on the same cell

In UITableViewCell there are different buttons and when I click on any button its action is being performed on all the cells, but I want that when I press the button then the action will be shown on the label of the same cell, I know I need to put them in array but how...?
when I click on the button one value is being incremented and it should be shown on the label of the same cell
here is the code:-
-(UITableViewCell *) tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath{
static NSString *CellIdentifier = #"Cell";
UITableViewCell *cell=[tableView dequeueReusableCellWithIdentifier:CellIdentifier];
cell=[[UITableViewCell alloc]initWithStyle:UITableViewCellStyleDefault reuseIdentifier:CellIdentifier];
likeShow=[[UILabel alloc]initWithFrame:CGRectMake(0, 160, 80, 20)];
likeBtn=[UIButton buttonWithType:UIButtonTypeCustom];
[likeBtn addTarget:self action:#selector(likeFn) forControlEvents:UIControlEventTouchUpInside];
likeBtn.frame=CGRectMake(0, 110, 90, 50);
[likeBtn setTitle:#"Like" forState:UIControlStateNormal];
[likeBtn setTitleColor:[UIColor blackColor] forState:UIControlStateNormal];
[cell addSubview:likeBtn];
[cell addSubview:likeShow];
return cell;
}
This is the action of the button
-(void)likeFn{
NSString *str;
NSMutableString *mystring=[NSMutableString string];
likeCount++;
str =[NSString stringWithFormat:#"%d",likeCount];
NSString *world = #"Like";
NSString *helloWorld = [world stringByAppendingString:str];
likeShow.text=helloWorld;
}
Try the below code
- (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath {
NSString *CellIdentifier = [NSString stringWithFormat:#"Cell-%d",indexPath.row];
UITableViewCell *cell=[tableView dequeueReusableCellWithIdentifier:CellIdentifier];
if (cell == nil)
{
cell=[[UITableViewCell alloc]initWithStyle:UITableViewCellStyleDefault reuseIdentifier:CellIdentifier];
//[cell clearsContextBeforeDrawing];
}
cell.selectionStyle = UITableViewCellSelectionStyleNone;
int lbltag = 1000;
UIButton *likeBtn = nil;
UILabel *likeShow = nil;
if ([cell viewWithTag:lbltag])
{
likeShow = (UILabel*)[cell viewWithTag:lbltag];
}
else
{
likeShow=[[[UILabel alloc]initWithFrame:CGRectMake(0, 0, 80, 20)] autorelease];
likeShow.text = [NSString stringWithFormat:#"%d likes",[[_marrTest objectAtIndex:indexPath.row] intValue]];
likeShow.tag = lbltag;
[cell addSubview:likeShow];
}
if ([cell viewWithTag:indexPath.row+1])
{
likeBtn = (UIButton*)[cell viewWithTag:indexPath.row+1];
}
else
{
likeBtn=[UIButton buttonWithType:UIButtonTypeCustom];
likeBtn.tag = indexPath.row+1;
[likeBtn addTarget:self action:#selector(likeFn:) forControlEvents:UIControlEventTouchUpInside];
likeBtn.frame=CGRectMake(90, 0, 90, 50);
[likeBtn setTitle:#"Like" forState:UIControlStateNormal];
[likeBtn setTitleColor:[UIColor blackColor] forState:UIControlStateNormal];
[cell addSubview:likeBtn];
}
return cell;
}
-(void)likeFn:(UIButton*)btnClicked
{
NSString *strLikes = [_marrTest objectAtIndex:btnClicked.tag-1];
int likeCount = [strLikes intValue] + 1;
[_marrTest replaceObjectAtIndex:btnClicked.tag-1 withObject:[NSString stringWithFormat:#"%d",likeCount]];
NSIndexPath *selectedIndexPath = [NSIndexPath indexPathForRow:btnClicked.tag-1 inSection:0];
UITableViewCell *cell = [self.tableView cellForRowAtIndexPath:selectedIndexPath];
UILabel *requiredLabel = (UILabel*)[cell viewWithTag:1000];
NSString *str = requiredLabel.text;
//str = [str stringByAppendingFormat:#"selected %#", str];
requiredLabel.text = #"";
requiredLabel.text = [NSString stringWithFormat:#"%d likes",[[_marrTest objectAtIndex:btnClicked.tag-1] intValue]];
//do what ever you want with the label
}
Create cell in separate nib file. add button and label for for that cell.
Also create a view class for that cell and set class for cell in nib file as class you created. Make outlet form nib to class file. Also create action for button and implement action. and use that cell in your table view.
-(UITableViewCell *) tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath{
static NSString *CellIdentifier = #"Cell";
UITableViewCell *cell=[tableView dequeueReusableCellWithIdentifier:CellIdentifier];
cell=[[UITableViewCell alloc]initWithStyle:UITableViewCellStyleDefault reuseIdentifier:CellIdentifier];
likeShow=[[UILabel alloc]initWithFrame:CGRectMake(0, 160, 80, 20)];
likeBtn=[UIButton buttonWithType:UIButtonTypeCustom];
[likeBtn addTarget:self action:#selector(likeFn::) forControlEvents:UIControlEventTouchUpInside];
likeBtn.frame=CGRectMake(0, 110, 90, 50);
[likeBtn setTitle:#"Like" forState:UIControlStateNormal];
[likeBtn setTitleColor:[UIColor blackColor] forState:UIControlStateNormal];
[cell.contentView addSubview:likeBtn];
[cell.contentView addSubview:likeShow];
return cell;
}
-(void)likeFn:(UIButton *)sender :(UIEvent *)event{
NSSet *touches = [event allTouches];
UITouch *touch = [touches anyObject];
CGPoint currentTouchPosition = [touch locationInView:self.view];
NSIndexPath *indexPath = [self.tableView indexPathForRowAtPoint:currentTouchPosition];
UITableViewCell *cell = [self.tableView cellForRowAtIndexPath:indexPath];
NSString *str;
NSMutableString *mystring=[NSMutableString string];
likeCount++;
str =[NSString stringWithFormat:#"%d",likeCount];
NSString *world = #"Like";
NSString *helloWorld = [world stringByAppendingString:str];
for(id subView in cell.contentView.subviews){
{
if([subView isKindOfClass:[UILabel class]]){
UILabel *tmpLabel = (UILabel *)subView;
tmpLabel.text=helloWorld;
}
}
}
Try this code it may help you
try setting tags as:
likeBtn.tag = indexPath.row;
likeShow.tag = indexPath.row;
and in the likeFn:
- (void)likeFn: (id)sender {
UIButton * btn = (UIButton*)sender;
//check if the btn tag and label tag are same.
}
Check with this code.This may helpful for you.
- (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath {
NSString *CellIdentifier = #"Cell";
UITableViewCell *cell=[tableView dequeueReusableCellWithIdentifier:CellIdentifier];
if (cell == nil)
{
cell=[[UITableViewCell alloc]initWithStyle:UITableViewCellStyleDefault reuseIdentifier:CellIdentifier];
[cell clearsContextBeforeDrawing];
}
cell.selectionStyle = UITableViewCellSelectionStyleNone;
likeShow=[[UILabel alloc]initWithFrame:CGRectMake(0, 160, 80, 20)];
likeBtn=[UIButton buttonWithType:UIButtonTypeCustom];
[likeBtn addTarget:self action:#selector(likeFn) forControlEvents:UIControlEventTouchUpInside];
likeBtn.frame=CGRectMake(0, 110, 90, 50);
[likeBtn setTitle:#"Like" forState:UIControlStateNormal];
[likeBtn setTitleColor:[UIColor blackColor] forState:UIControlStateNormal];
[cell addSubview:likeBtn];
[cell addSubview:likeShow];
return cell;
}
USE didSelectRowAtIndexPath method
- (void)tableView:(UITableView *)tableView didSelectRowAtIndexPath:(NSIndexPath *)indexPath {
UITableViewCell *cell=[tableView dequeueReusableCellWithIdentifier:CellIdentifier];
return;
}

UIProgressView hides when scroll the tableview

In my iphone app i am having a button, when I click on the button, download operation starts and i am replacing the button with UIProgressView. This UIProgressView will show the download progress. But once a UIProgressView is added, when I scroll it is disappeared. Here is my code:
// Customize the appearance of table view cells.
- (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath
{

cell = [self getCellContentView:CellIdentifier];
cell.cellitemImage = (UIImageView *)[cell viewWithTag:2];
cell.cellItemButton = (UIButton *)[cell viewWithTag:3];
DataBaseClass *itemObj = [appDelegate.itemArray objectAtIndex:indexPath.row];
NSString *url;
if([itemObj.itemStatus isEqualToString:#"Available"]){

}
[cell.cellitemImage setImageWithURL:[NSURL URLWithString:url] placeholderImage:[UIImage imageNamed:#"item01.png"]];
cell.cellItemName.text = [NSString stringWithFormat:#"%#",itemObj.itemName];
return cell;
}
- (void)download{

UIMenuItemCell *cell = [(UIMenuItemCell *)[[clickedBtnSender superview] superview] retain];
myprogressView = [[[CustomProgressView alloc]initWithFrame:CGRectMake(25, 140, 100, 21)] retain];
myprogressView.tag = selectedTag;
btn.hidden = YES;
for (UIProgressView *currentProgress in cell.contentView.subviews) {
if ([currentProgress isKindOfClass:[UIProgressView class]]){
[currentProgress removeFromSuperview];
}
}
[cell.contentView addSubview:myprogressView];
}
Please help.
EDIT
- (UIMenuItemCell *) getCellContentView:(NSString *)cellIdentifier {
CGRect CellFrame = CGRectMake(0, 0, 150, 60);
CGRect imgFrame = CGRectMake(20, 48, 110, 123);
CGRect btnFrame = CGRectMake(25, 140, 100, 26);
CGRect progressFrame = CGRectMake(25, 140, 100, 21);

cell.frame = CellFrame;
//Initialize ImageView

itemImg.tag = 2;
[cell.contentView addSubview:itemImg];
//Initialize Button
itemBtn = [UIButton buttonWithType:UIButtonTypeCustom];
itemBtn.frame = btnFrame;
itemBtn.tag = 3;
itemBtn.titleLabel.textColor = [UIColor blueColor];
itemBtn.titleLabel.font = [UIFont systemFontOfSize:9.0];
[cell.contentView addSubview:itemBtn];
//Initialize ProgressView
itemProgView = [[CustomProgressView alloc]initWithFrame:progressFrame];
itemProgView.tag = 4;
//[cell.contentView addSubview:itemProgView];
return cell;
}
I think you need to have unique cellIdentifier for each cell
- (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath
{
NSString *CellIdentifier = [NSString stringWithFormat:#"Cell%d", indexPath.row];
UIMenuItemCell *cell = [tableView dequeueReusableCellWithIdentifier:CellIdentifier];
if(cell == nil) {
cell = [self getCellContentView:CellIdentifier];
// Some codes here
}
return cell;
}
Additional based on you last edit
Change
UIMenuItemCell *cell = [[UIMenuItemCell alloc] init];
to
UIMenuItemCell *cell = [[UIMenuItemCell alloc] initWithFrame:CellFrame reuseIdentifier:cellIdentifier];

iphone:UItableviewcell duplicates when using table reload

My tableview gets duplicated when I use [tableview reloadData].I used this to refresh the tableview when I move back.How could I overcome the issue?
This is my code.
#define kMyTag 1
#define despTag 2
#define subTag 3
- (void)viewWillAppear:(BOOL)animated{
[super viewWillAppear:animated];
[self.tableview reloadData];
}
- (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath {
AsyncImageView *asyncImageView = nil;
UILabel *label = nil;
UITableViewCell *cell = [tableView dequeueReusableCellWithIdentifier:nil];
if (cell == nil) {
cell = [[UITableViewCell alloc] initWithStyle:UITableViewCellStyleDefault reuseIdentifier:nil] ;
UILabel *mainLabel=[[UILabel alloc]init];
mainLabel.tag = kMyTag; // define kMyTag in your header file using #define
mainLabel.frame=CGRectMake(95, 0, 170, 30);
mainLabel.font = [UIFont boldSystemFontOfSize:14];
mainLabel.backgroundColor=[UIColor clearColor];
[cell.contentView addSubview:mainLabel];
UILabel *despLabel=[[UILabel alloc]init];
despLabel.tag=despTag;
despLabel.frame=CGRectMake(95, 25, 190, 20);
despLabel.font= [UIFont systemFontOfSize:12];
despLabel.backgroundColor=[UIColor clearColor];
[cell.contentView addSubview:despLabel];
} else {
label = (UILabel *) [cell.contentView viewWithTag:LABEL_TAG];
}
switch([indexPath section]){
case 0:
{
NSString *urlString = [img objectAtIndex:indexPath.row];
urlString=[urlString stringByReplacingOccurrencesOfString:#" " withString:#"%20"];
tname=[mname objectAtIndex:indexPath.row];
tprice=[mprice objectAtIndex:indexPath.row];
tquan=[mquan objectAtIndex:indexPath.row];
tspice=[mspice objectAtIndex:indexPath.row];
UILabel *mainLabel=(UILabel *)[cell.contentView viewWithTag: kMyTag];
mainLabel.text = [NSString stringWithFormat:#"%#",tname];
UILabel *despLabel=(UILabel *)[cell.contentView viewWithTag: despTag];
despLabel.text = [NSString stringWithFormat:#"Qty :%# Spice: %#",tquan,tspice];
UILabel *subLabel=(UILabel *)[cell.contentView viewWithTag: subTag];
float pric=[tprice floatValue];
subLabel.text = [NSString stringWithFormat:#"Price :%# %.2f",currencyType, pric];
}
}
}
Overcomes the issue by removing all the objects from array,then reselects the DB table & reloads uitableview.
it happens because you are not passing any value in dequeueReusableCellWithIdentifier
pass a string value and then use it in reuseIdentifier also
