TableView Image Load Problem.(Full Code fot the tableCell) - ios4

(UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath {
dictionary = [QuestionMutableArray objectAtIndex:0];
static NSString *CellIdentifier = #"BeginingCell";
BeginingCell *cell=(BeginingCell *)[tableView dequeueReusableCellWithIdentifier:CellIdentifier];
if (cell == nil) {
NSArray *topLevelObjects=[[NSBundle mainBundle] loadNibNamed:#"BeginingCell" owner:self options:nil ];
for(id CurrentObject in topLevelObjects)
{
if ([CurrentObject isKindOfClass:[BeginingCell class]]) {
cell=(BeginingCell *) CurrentObject;
break;
}
}
}
// Configure the cell.
if(indexPath.row==0)
{
cell.SectionTitle.text=[dictionary objectForKey:#"question"];
cell.Option1.text=[dictionary objectForKey:#"option1"];
cell.Option2.text=[dictionary objectForKey:#"option2"];
cell.Option3.text=[dictionary objectForKey:#"option3"];
cell.Option4.text=[dictionary objectForKey:#"option4"];
UIImage *imgDef=[UIImage imageNamed:#"man_kirstie_alley.jpg"];
[cell.myImageView setImage:imgDef];
[MyTestArray release];
[cell.button1 setTitle:#"A." forState:UIControlStateNormal];
[cell.button2 setTitle:#"B." forState:UIControlStateNormal];
[cell.button3 setTitle:#"C." forState:UIControlStateNormal];
[cell.button4 setTitle:#"D." forState:UIControlStateNormal];
}
return cell;
}

I think you must create a cell first. You could use a default cell like this:
- (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath {
static NSString *CellIdentifier = #"Cell";
//---try to get a reusable cell---
UITableViewCell *cell = [tableView
dequeueReusableCellWithIdentifier:CellIdentifier];
//---create new cell if no reusable cell is available---
if (cell == nil) {
cell = [[[UITableViewCell alloc] initWithStyle:UITableViewCellStyleDefault
reuseIdentifier:CellIdentifier] autorelease];
}
//---You would set the image here---
UIImage *imgDef=[UIImage imageNamed:#"man_kirstie_alley.jpg"];
cell.image = imgDef;
return cell;

Displaying a sum total of cells in a dynamic tableview

I have a problem that Im sure many objectiveC developers would be able to solve pretty easily. Im developing an app which is a dynamic tableview with different groups that the user can create. The user can enter a number of groups with different totals. I am trying to sum the total of all the groups created.
The IBAction I am using to calculate the subtotal is
- (IBAction)Calculate:(id)sender {
//---------------
NSInteger Tempsum = [[_dataArray valueForKeyPath:#"#sum.name2"] integerValue];
_TotalAnimals.text = [[NSString alloc] initWithFormat:#"%.1ld", (long)Tempsum];
//--------------
}
I have created the following code in the .m file of my tableview and also created a NSArray property called;
#property NSArray *dataArray;
however I am unsure as to the correct code to use to be able to link the result ( #"#sum.name2" ) to the text value in the Tableviewcontroller ( _TotalAnimals.text)
Any help with this problem would be much appreciated. below is the full code for the .m file

how to make the background of UITableView cell transparent in iphone?

I wrote the following code to make my cell transparent as I do with UITableView
- (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath{
static NSString *CellIdentifier = #"Nsubject";
SubjectsCell *cell = (SubjectsCell*)[tableView dequeueReusableCellWithIdentifier:CellIdentifier];
if (cell == nil) {
[[NSBundle mainBundle] loadNibNamed:#"mySubjectCell" owner:self options:nil];
cell=subjCell;
UIView* backgroundView = [ [ [ UIView alloc ] initWithFrame:CGRectZero ] autorelease ];
cell.backgroundView = backgroundView;
for ( UIView* view in cell.contentView.subviews )
{
view.backgroundColor = [ UIColor clearColor ];
}
}
[cell SetTitle:[subjectsArr objectAtIndex:indexPath.row]];
return cell;
}
anybody can help me
In viewDidLoad you can simply add
self.tableView.backgroundColor = [UIColor clearColor];
You do not need to make your own view like you have above.

UITableviewCell with RemoveButton

I have a one Tableview in that i added a UIButton to each Tableviewcell named it as Remove
when i click the remove button the appropriate cell data will be remove from the tableview
and i added UIButton programmatically
now i want to perform remove option.
Thanks in Advance....
try this one:
- (UITableViewCell *)tableView:(UITableView *)aTableView cellForRowAtIndexPath:(NSIndexPath *)indexPath {
static NSString *s = #"cell";
UITableViewCell *cell = (UITableViewCell *)[tableView dequeueReusableCellWithIdentifier:s];
AsyncImageView *asyncImage;
UIButton *button = nil;
if ( cell == nil ) {
cell = [[[UITableViewCell alloc]initWithReuseIdentifier:s] autorelease];
UIButton *removeBtn = [UIButton buttonWithType:UIButtonTypeCustom];
[button addTarget:self
action:#selector(remove:)
forControlEvents:UIControlEventTouchUpInside];
….
[cell addSubview:button];
}
…..
return cell;
}
-(void)remove:(UIButton*)btn{
UITableViewCell *cell = (UITableViewCell *)btn.superview;
NSIndexPath* index = [self.tableView indexPathForCell:cell];
[peopleList removeObjectAtIndex:index.row];
[self.tableView deleteRowsAtIndexPaths:[NSArray arrayWithObject:index]
withRowAnimation:UITableViewRowAnimationRight];

I have edited my code in my question...it works fine nw....AnyOne willing to use searchbar in tableview in Iphones can refer the code.

Is there anyway to populate a UITableView with an array but persist checkmarks?

I have an app that has a tab bar, each tab contains a separate table. The first table uses core data to persist its entries and checkmarks. The second table on the second tab uses an NSMutableArray to populate it (I would use core data but I would have to pre populate it and this table does not allow that) I would like to persist check marks the same way I do in the first table with core data but something is wrong. The code looks like this:
-(void)viewDidLoad {
[super viewDidLoad];
airport = [[NSMutableArray alloc] init];
[airport addObject:#"Passport"];
}
-(NSInteger)numberOfSectionsInTableView:(UITableView *)tableView {
return 1;
}
// Customize the number of rows in the table view.
- (NSInteger)tableView:(UITableView *)tableView numberOfRowsInSection:(NSInteger)section {
return [airport count];
}
// Customize the appearance of table view cells.
- (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] autorelease];
}
// Set up the cell...
NSString *cellValue = [airport objectAtIndex:indexPath.row];
cell.textLabel.text = cellValue;
//[cell setAccessoryType:UITableViewCellAccessoryDisclosureIndicator];
NSManagedObject *item = [[self fetchedResultsController] objectAtIndexPath:indexPath];
cell.textLabel.text = [item valueForKey:#"name"]; //CHANGED TO DETAIL
if ([[item valueForKey:#"check"] boolValue]) {
cell.accessoryType = UITableViewCellAccessoryCheckmark;
} else {
cell.accessoryType = UITableViewCellAccessoryNone;
}
cell.selectionStyle = UITableViewCellSelectionStyleNone;
return cell;
}
- (void)tableView:(UITableView *)tableView didSelectRowAtIndexPath:(NSIndexPath *)indexPath {
NSManagedObject *selectedObject = [self.fetchedResultsController objectAtIndexPath:indexPath];
if ([[selectedObject valueForKey:#"check"] boolValue]) {
[selectedObject setValue:[NSNumber numberWithBool:NO] forKey:#"check"];
} else {
[selectedObject setValue:[NSNumber numberWithBool:YES] forKey:#"check"];
}
UITableViewCell *thisCell = [tableView cellForRowAtIndexPath:indexPath];
if (thisCell.accessoryType == UITableViewCellAccessoryNone) {
thisCell.accessoryType = UITableViewCellAccessoryCheckmark;
} else {
thisCell.accessoryType = UITableViewCellAccessoryNone;
}
[tableView deselectRowAtIndexPath:indexPath animated:NO];
}
I believe the line cell.textLabel.text = [item valueForKey#"name"];
is whats causing it. All that I would like for this to do is have the table populated from the array and check marks persisted. Any help is GREATLY appreciated. Thanks in advance.
This line is replacing the cell text:
cell.textLabel.text = [item valueForKey:#"name"];
that was initially assigned by these lines:
NSString *cellValue = [airport objectAtIndex:indexPath.row];
cell.textLabel.text = cellValue;
Why are your using the "name" property of "item"?
