Reloading images in the buttons present in the table view - objective-c

Question

In my table view I have 4 UIButtons, 2 in each row of table view. Initially all the buttons have an image on them (they're hardcoded). Now there is a button in my app which when tapped replaces the images on the buttons with new ones using the setImage method and then reloads the table view. But unfortunately I am getting the old table view only i mean with old images. How can I get the new images on the buttons?
My cellForRowAtIndexPath implementation:-// 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] initWithFrame:CGRectZero reuseIdentifier:CellIdentifier] autorelease];
// }
if (cell == nil) {
cell = [[[UITableViewCell alloc] initWithStyle:UITableViewCellStyleDefault reuseIdentifier:CellIdentifier] autorelease];
}
if(indexPath.row == 0)
{
button1=[[UIButton alloc] initWithFrame:CGRectMake(15,5,100,87)];
[button1 setImage:[UIImage imageNamed:#"BUTTON.png"] forState:UIControlStateNormal];
[button1 addTarget:self action:#selector(ClickTo:) forControlEvents:UIControlEventTouchUpInside];
[cell.contentView addSubview:self.button1];
button2=[[UIButton alloc] initWithFrame:CGRectMake(135,5,100,87)];
[button2 setImage:[UIImage imageNamed:#"TURN OFF.png"] forState:UIControlStateNormal];
[button2 addTarget:self action:#selector(ClickTo:) forControlEvents:UIControlEventTouchUpInside];
[cell.contentView addSubview:button2];
}
else if(indexPath.row == 1)
{
button3=[[UIButton alloc] initWithFrame:CGRectMake(15,5,100,87)];
[button3 setImage:[UIImage imageNamed:#"JUMP.png"] forState:UIControlStateNormal];
[button3 addTarget:self action:#selector(ClickTo:) forControlEvents:UIControlEventTouchUpInside];
[cell.contentView addSubview:button3];
button4=[[UIButton alloc] initWithFrame:CGRectMake(135,5,100,87)];
[button4 setImage:[UIImage imageNamed:#"CLOSE.png"] forState:UIControlStateNormal];
[button4 addTarget:self action:#selector(ClickTo:) forControlEvents:UIControlEventTouchUpInside];
[cell.contentView addSubview:button4];
}
else
{
// Do something here
}
return cell;
}

Answer 1

You are probably setting the image for the wrong state:
[myButton setImage:[UIImage imageNamed:#"myImage.png"] forState:UIControlStateNormal];
You need to set the correct value for UIControlStateNormal - where correct means the one that matches your buttons' current state(s).

Answer 2

It Seems that you have hardcoded images in cell for row method, so whenever you are reloading your tableview , they will have same images.
So If you like to change them then take a boolean varible and Update it like :
(UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath {
static NSString *CellIdentifier = #"Cell";
UITableViewCell *cell = [tableView dequeueReusableCellWithIdentifier:CellIdentifier];
// if (cell == nil) {
// cell = [[[UITableViewCell alloc] initWithFrame:CGRectZero reuseIdentifier:CellIdentifier] autorelease];
// }
if (cell == nil) {
cell = [[[UITableViewCell alloc] initWithStyle:UITableViewCellStyleDefault reuseIdentifier:CellIdentifier] autorelease];
}
if(indexPath.row == 0)
{
button1=[[UIButton alloc] initWithFrame:CGRectMake(15,5,100,87)];
[button1 setImage:[UIImage imageNamed:#"BUTTON.png"] forState:UIControlStateNormal];
[button1 addTarget:self action:#selector(ClickTo:) forControlEvents:UIControlEventTouchUpInside];
[cell.contentView addSubview:self.button1];
button2=[[UIButton alloc] initWithFrame:CGRectMake(135,5,100,87)];
[button2 setImage:[UIImage imageNamed:#"TURN OFF.png"] forState:UIControlStateNormal];
[button2 addTarget:self action:#selector(ClickTo:) forControlEvents:UIControlEventTouchUpInside];
[cell.contentView addSubview:button2];
}
else if(indexPath.row == 1)
{
button3=[[UIButton alloc] initWithFrame:CGRectMake(15,5,100,87)];
[button3 setImage:[UIImage imageNamed:#"JUMP.png"] forState:UIControlStateNormal];
[button3 addTarget:self action:#selector(ClickTo:) forControlEvents:UIControlEventTouchUpInside];
[cell.contentView addSubview:button3];
button4=[[UIButton alloc] initWithFrame:CGRectMake(135,5,100,87)];
[button4 setImage:[UIImage imageNamed:#"CLOSE.png"] forState:UIControlStateNormal];
[button4 addTarget:self action:#selector(ClickTo:) forControlEvents:UIControlEventTouchUpInside];
[cell.contentView addSubview:button4];
}
else
{
// Do something here
}
if(myflag)
{
[button1 setImage:[UIImage imageNamed:#"changedImage1"] forState:UIControlStateNormal];
[button2 setImage:[UIImage imageNamed:#"changedImage2"] forState:UIControlStateNormal];
[button3 setImage:[UIImage imageNamed:#"changedImage3"] forState:UIControlStateNormal];
[button4 setImage:[UIImage imageNamed:#"changedImage4"] forState:UIControlStateNormal];
}
return cell;
}
// In Click to Method Set myflag yes and reload table
-(void)ClickTo:(IBAction )sender
{
myflag=YES;
[tableview reloadData];
}
