The UITableView row cannot be loaded after row 13. The data reload from 0 again.
i found out that the row is loaded until 13. And the row will start again from beginning.
If I set the height of each row to 20. All the row can be loaded in one screen then everything fine.
but I need to set the height to 40. then it has the problem.

[groupnamelabel addGestureRecognizer:tap];

}
}
return cell;
I found out the problem is
self.MyGrouptableview = [[UITableView alloc] initWithFrame:CGRectMake(0,65,screenWidth,screenHeight-150) style:UITableViewStylePlain];
If I set the height of the tableview long enough everything would be alright but the user cannot scroll to the bottom.

I have to create custom UITableView and generally cell has UIImageView, and two UILabel when image of UIImageView is depend upon content which i got from server. so some cell has image and some has no image.
Problem is that when i use reusability of cell then previous UIImageView's image remain as it.. how can i remove it and implement my content on cell proper way.
Following is mine code.
- (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath
{
NSString *isImgOfTable = [[self.listOfEvents objectAtIndex:indexPath.row] objectForKey:#"EventImage"];
NSString *CellIdentifier = #"Cell";
//NSString *CellIdentifier = [NSString stringWithFormat:#"S%1dR%1d", indexPath.section, indexPath.row];
UITableViewCell *cell = [tableView dequeueReusableCellWithIdentifier:CellIdentifier];
if(cell == nil)
{
cell = [[UITableViewCell alloc]initWithStyle:UITableViewCellStyleDefault reuseIdentifier:CellIdentifier];
cell.selectionStyle = UITableViewCellSelectionStyleNone;
if([isImgOfTable length] > 0)
{
UIImageView *imgOfEvent = [[UIImageView alloc] init];
imgOfEvent.tag = 101;
[cell.contentView addSubview: imgOfEvent];
}
UILabel *lblEventTitle = [[UILabel alloc] init];
lblEventTitle.tag = 102;
[cell.contentView addSubview:lblEventTitle];
UILabel *lblDescription = [[UILabel alloc] init];
lblDescription.tag = 103;
[cell.contentView addSubview:lblDescription];
}
if([isImgOfTable length] > 0)
{
NSString *newPath = #"";
UIImageView *imgEvent = (UIImageView *) [cell.contentView viewWithTag:101];
imgEvent.userInteractionEnabled = YES;
newPath = [[GeneralClass getDocumentDirectory] stringByAppendingPathComponent:[[self.listOfEvents objectAtIndex:indexPath.row] objectForKey:#"EventImage"]];
imgEvent.frame = CGRectMake(mainX, 4, 45, 45);
imgEvent.backgroundColor = [UIColor colorWithRed:(187/255.f) green:(226/255.f) blue:(255/255.f) alpha:1.0f];
imgEvent.layer.cornerRadius = 7;
imgEvent.layer.borderColor = [UIColor colorWithRed:(224/255.f) green:(224/255.f) blue:(224/255.f) alpha:1.0f].CGColor;
imgEvent.layer.borderWidth = 1;
imgEvent.clipsToBounds = YES;
imgEvent.image = [UIImage imageWithContentsOfFile:newPath];
}
UILabel *lblEventTitle = (UILabel*) [cell.contentView viewWithTag:102];
.
.
// Code of UILabel *lblEventTitle
UILabel *lblEventDescription = (UILabel*) [cell.contentView viewWithTag:103];
.
.
// Code of UILabel *lblEventDescription
return cell;
}
NOTE: I must want to use reusability of cell. I dont want to fix such like
NSString *CellIdentifier = [NSString stringWithFormat:#"S%1dR%1d", indexPath.section, indexPath.row];
And also i am not used UITableViewCell class so may be it is not possible to call/override prepareForReuse
Please give me you suggestion.
Check this code it help full to you.

Might i suggest subclassing UITableViewCell and using prepareForReuse
-(void)prepareForReuse
{
labelOne = #"Default text 1";
labelTwo = #"Default label 2";
[imageView setImage:nil]; //Or you could set a default image?
}
I have a UITable that reuses cells. Each cell has an image dependant on a condition. The correct images are always used however when cells are reused the old image is displayed behind the new one. I have tried to remove the uiimageview before adding a new subview however it has no effect.
-(UITableViewCell *) tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath {
static NSString *simpTableIden = #"simpTableIden";
UITableViewCell *cell = [tableView dequeueReusableCellWithIdentifier:simpTableIden];
if (cell == nil) {
cell = [[UITableViewCell alloc] initWithStyle:UITableViewCellStyleDefault reuseIdentifier:simpTableIden];
}
NSUInteger row = [indexPath row];
cell.textLabel.text = [[self.achievements objectForKey:[keys objectAtIndex:row]] objectForKey:#"name"];
CGRect picFrame = CGRectMake(cell.frame.size.width-cell.frame.size.height, 0, cell.frame.size.height, cell.frame.size.height);
UIImage *greyDot = [UIImage imageNamed:#"greyDot.png"];
UIImage *whiteDot = [UIImage imageNamed:#"whiteDot.png"];
UIImageView *achievImg = [[UIImageView alloc] init];
tableView.backgroundColor = [UIColor clearColor];
achievImg.frame=picFrame;
if ([[[self.achievements objectForKey:[keys objectAtIndex:row]] objectForKey:#"achieved"] boolValue]) {
achievImg.image = whiteDot;
}
else {
achievImg.image = greyDot;
}
[achievImg removeFromSuperview];
[cell.contentView addSubview:achievImg];
return cell;
}
Any help would be greatly appreciated?
The problem is each time cellForRowAtIndexPath: is called you create a new imageview.
I corrected your code as follows:
Here we create an imageView once for each new new cell and replace it's image every time cellForRowAtIndexPath: is called:
-(UITableViewCell *) tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath {
static NSString *simpTableIden = #"simpTableIden";
UITableViewCell *cell = [tableView dequeueReusableCellWithIdentifier:simpTableIden];
UIImageView *achievImg = nil;
if (cell == nil) {
cell = [[UITableViewCell alloc] initWithStyle:UITableViewCellStyleDefault reuseIdentifier:simpTableIden];
//New Cell ... Create Image view
achievImg = [[UIImageView alloc] init];
achievImg.tag = 10;
[cell.contentView addSubview:achievImg];
}
else{
//Old cell...get previously createdd imageview
achievImg = (UIImageView*)[cell.contentView viewWithTag:10];
}
NSUInteger row = [indexPath row];
cell.textLabel.text = [[self.achievements objectForKey:[keys objectAtIndex:row]] objectForKey:#"name"];
CGRect picFrame = CGRectMake(cell.frame.size.width-cell.frame.size.height, 0, cell.frame.size.height, cell.frame.size.height);
UIImage *greyDot = [UIImage imageNamed:#"greyDot.png"];
UIImage *whiteDot = [UIImage imageNamed:#"whiteDot.png"];
tableView.backgroundColor = [UIColor clearColor];
achievImg.frame=picFrame;
if ([[[self.achievements objectForKey:[keys objectAtIndex:row]] objectForKey:#"achieved"] boolValue]) {
achievImg.image = whiteDot;
}
else {
achievImg.image = greyDot;
}
//You don't need this because it doesn't have a superview in the first place..it's new
//[achievImg removeFromSuperview];
return cell;
}
try like this,
-(UITableViewCell *) tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath {
static NSString *simpTableIden = #"simpTableIden";
UITableViewCell *cell = [tableView dequeueReusableCellWithIdentifier:simpTableIden];
if (cell == nil) {
cell = [[UITableViewCell alloc] initWithStyle:UITableViewCellStyleDefault reuseIdentifier:simpTableIden];
NSUInteger row = [indexPath row];
cell.textLabel.text = [[self.achievements objectForKey:[keys objectAtIndex:row]] objectForKey:#"name"];
CGRect picFrame = CGRectMake(cell.frame.size.width-cell.frame.size.height, 0, cell.frame.size.height, cell.frame.size.height);
UIImage *greyDot = [UIImage imageNamed:#"greyDot.png"];
UIImage *whiteDot = [UIImage imageNamed:#"whiteDot.png"];
UIImageView *achievImg = [[UIImageView alloc] init];
tableView.backgroundColor = [UIColor clearColor];
achievImg.frame=picFrame;
if ([[[self.achievements objectForKey:[keys objectAtIndex:row]] objectForKey:#"achieved"] boolValue]) {
achievImg.image = whiteDot;
}
else {
achievImg.image = greyDot;
}
[achievImg removeFromSuperview];
[cell.contentView addSubview:achievImg];
}
return cell;
}
You are always adding the imageView to the contentView of the cell. If the cell is reused that will lead to multiple imageViews in cell.
You can give a tag to the imageView. Always check if there is a view will same tag in the contentView of cell. If not add the imageView.
UIImageView *achievImg = (UIImageView *)[cell.contentView viewWithTag:55];
if(!achievImg){
achievImg = [[UIImageView alloc] init];
achievImg.tag = 55;
[cell.contentView addSubView:achievImg];
}
When I scroll my tableview, the text gets all mashed up from the cells below. It's probably cause I recreate the UILabels every time cellForRow gets loaded, but I wouldn't know how to fix it:
(UITableViewCell *)tableView:(UITableView *)tableView
cellForRowAtIndexPath:(NSIndexPath *)indexPath
{
NSInteger row = [indexPath row];
NSDictionary *currentRowDictionary = nil;
if (tableView == [[self searchDisplayController] searchResultsTableView])
currentRowDictionary = [[self searchResults] objectAtIndex:row];
else
currentRowDictionary = [[self tableData] objectAtIndex:row];
NSString *voornaam = [currentRowDictionary objectForKey:#"voornaam"];
NSString *achternaam = [currentRowDictionary objectForKey:#"achternaam"];
NSString *tussenvoegsel = [currentRowDictionary objectForKey:#"tussenvoegsel"];
voornaamLbl = [[[UILabel alloc] initWithFrame:CGRectMake(5, 10, 300, 40)] autorelease];
voornaamLbl.font = [UIFont fontWithName:#"TrebuchetMS-Bold" size:19];
voornaamLbl.text = voornaam;
voornaamLbl.numberOfLines = 0;
[voornaamLbl sizeToFit];
tussenvoegselLbl = [[[UILabel alloc] initWithFrame:CGRectMake(voornaamLbl.frame.size.width + 10, 10, 300, 40)] autorelease];
tussenvoegselLbl.text = tussenvoegsel;
tussenvoegselLbl.numberOfLines = 0;
[tussenvoegselLbl sizeToFit];
static NSString *CellIdentifier = #"Cell";
UITableViewCell *cell = [tableView dequeueReusableCellWithIdentifier:CellIdentifier];
if (cell == nil)
{
cell = [[[UITableViewCell alloc] initWithStyle:UITableViewCellStyleDefault reuseIdentifier:CellIdentifier] autorelease];
}
[cell.contentView addSubview:voornaamLbl];
if ([tussenvoegsel length] != 0)
{
[cell.contentView addSubview:tussenvoegselLbl];
achternaamLbl = [[[UILabel alloc] initWithFrame:CGRectMake(voornaamLbl.frame.size.width +
tussenvoegselLbl.frame.size.width + 15, 10, 300, 40)] autorelease];
} else {
achternaamLbl = [[[UILabel alloc] initWithFrame:CGRectMake(voornaamLbl.frame.size.width + 10, 10, 300, 40)] autorelease];
}
achternaamLbl.text = achternaam;
achternaamLbl.numberOfLines = 0;
[achternaamLbl sizeToFit];
[cell.contentView addSubview:achternaamLbl];
return cell;
}
You alloc and init new labels for everytime a cell is used. Cells are reused during scroll so your multiplying labels each time.
The best way is to create a seperate UITableViewCell subclass that creates the label on load, then in cellForRowAtIndexPath you use your new cell subclass and set the labels text
The end of this tutorial can help with cell subclasses http://www.raywenderlich.com/5138/beginning-storyboards-in-ios-5-part-1
As I scroll down the list, all the rows are there, but they keep adding more subviews the more they appear on the visible frame
- (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath {
static NSString *reuse = #"RuleCell";
UITableViewCell* cell = [tableView dequeueReusableCellWithIdentifier:reuse];
if (cell == nil){
cell = [[UITableViewCell alloc] initWithStyle: UITableViewCellStyleDefault reuseIdentifier:reuse];
}
NSUInteger row = indexPath.row;
[self createCell: cell onRow: row];
return cell;
}
- (void) createCell: (UITableViewCell*)cell onRow: (NSUInteger)row
{
UIImageView* bgImage = [[UIImageView alloc] initWithImage:[UIImage imageNamed:#"cell_background_spade_active.png"]];
cell.backgroundView = bgImage;
cell.textLabel.hidden = YES;
UILabel* titleLabel = [[UILabel alloc] initWithFrame: CGRectMake(100, CGRectGetHeight(cell.frame) / 2, 200, 50)];
titleLabel.text = [[self.ruleList objectAtIndex: row] objectForKey: TitleKey];
titleLabel.backgroundColor = [UIColor clearColor];
[cell.contentView addSubview: titleLabel];
}
I think you need to execute almost all of the logic that's in createCell: only within the if (cell == nil){ segment of your code. The part that should execute where you're currently calling createCell: is just getting a reference to the titleLabel and setting its text value.
To clarify, here's the kind of modification I'm suggesting (not tested, but should give the right idea):
- (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath {
static NSString *reuse = #"RuleCell";
UITableViewCell* cell = [tableView dequeueReusableCellWithIdentifier:reuse];
if (cell == nil){
cell = [[UITableViewCell alloc] initWithStyle: UITableViewCellStyleDefault reuseIdentifier:reuse];
[self setUpCell: cell];
}
NSUInteger row = indexPath.row;
UILabel *titleLabel = (UILabel *)[cell.contentView viewWithTag:42];
titleLabel.text = [[self.ruleList objectAtIndex: row] objectForKey: TitleKey];
return cell;
}
- (void) setUpCell: (UITableViewCell*)cell
{
UIImageView* bgImage = [[UIImageView alloc] initWithImage:[UIImage imageNamed:#"cell_background_spade_active.png"]];
cell.backgroundView = bgImage;
cell.textLabel.hidden = YES;
UILabel* titleLabel = [[UILabel alloc] initWithFrame: CGRectMake(100, CGRectGetHeight(cell.frame) / 2, 200, 50)];
titleLabel.tag = 42;
titleLabel.backgroundColor = [UIColor clearColor];
[cell.contentView addSubview: titleLabel];
}
I have a standard tableview here and I wanted to be able to add a space between each cell that is invisible/hidden that shows the background. What is the correct way of doing it?
Here is the code I am using:

// Set how tall each cell is
- (CGFloat)tableView:(UITableView *)tableView heightForRowAtIndexPath:(NSIndexPath *)indexPath
{
return 55;
}
Let me start by saying I did not read all your code. That said I have done exactly this. The first approach is to declare in the heightForCell a larger value for the cell above where the gap should be. The cell.contentView might need to have its clipToBounds set. I believe in this case the cell size should be set by setting the cell.frame.size (the origin is 0,0), and the contentsView and backgroundview properly sized too.
The second way to do it is to insert empty cells - cells with a different reuse identifier, and which are just empty cells with everything set to have a clear color.
Just use the trick to have spaces between each cells..
static NSString *CELL_ID2 = #"SOME_STUPID_ID2";
// even rows will be invisible
if (indexPath.row % 2 == 1)
{
UITableViewCell * cell2 = [tableView dequeueReusableCellWithIdentifier:CELL_ID2];
if (cell2 == nil)
{
cell2 = [[UITableViewCell alloc] initWithStyle:UITableViewCellStyleDefault
reuseIdentifier:CELL_ID2];
[cell2.contentView setAlpha:0];
[cell2 setUserInteractionEnabled:NO]; // prevent selection and other stuff
}
return cell2;
}
I just use different heights and alternate colours between cells.
- (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath
{
tableView.separatorStyle = UITableViewCellSeparatorStyleNone;
if (indexPath.row % 2 == 1)
{
static NSString *CellIdentifier = #"cellID1";
UITableViewCell *cell = (UITableViewCell *)[tableView dequeueReusableCellWithIdentifier:CellIdentifier];
if (cell == nil) {
cell = [[UITableViewCell alloc] initWithStyle:UITableViewCellStyleDefault
reuseIdentifier:CellIdentifier];
}
cell.backgroundColor = [UIColor colorWhite];
return cell;
} else {
static NSString *CellIdentifier2 = #"cellID2";
UITableViewCell *cell2 = (UITableViewCell *)[tableView dequeueReusableCellWithIdentifier:CellIdentifier2];
if (cell2 == nil) {
cell2 = [[UITableViewCell alloc] initWithStyle:UITableViewCellStyleDefault
reuseIdentifier:CellIdentifier2];
}
cell2.backgroundColor = [UIColor clearColor];
return cell2;
}
}
- (CGFloat)tableView:(UITableView *)tableView heightForRowAtIndexPath:(NSIndexPath *)indexPath
{
if (indexPath.row % 2 == 1) {
return 40.0;
} else {
return 2.0;
}
}
