how to change tableView Cell button on click in iphone
I have button in table view cell with background images set using this function.
- (UITableViewCell *)tableView:(UITableView *)tableView
cellForRowAtIndexPath:(NSIndexPath *)indexPath
{
UITableViewCell *cell = [tableView dequeueReusableCellWithIdentifier:
SectionsTableIdentifier];
cell.textLabel.text = self.names[self.keys];
if (cell.accessoryView == nil) {
UIImage *buttonUpImage = [UIImage imageNamed:#"button_up.png"];
UIImage *buttonDownImage = [UIImage imageNamed:#"button_down.png"];
UIButton *button = [UIButton buttonWithType:UIButtonTypeCustom];
[button setBackgroundImage:buttonUpImage
forState:UIControlStateNormal];
[button setBackgroundImage:buttonDownImage
forState:UIControlStateHighlighted];
[button setTitle:#"Send" forState:UIControlStateNormal];
[button sizeToFit];
[button addTarget:self
action:#selector(tappedButton:)
forControlEvents:UIControlEventTouchUpInside];
cell.accessoryView = button;
}
return cell;
}
Code for Tapped Button is :
- (void)tappedButton:(UIButton *)sender
{
NSInteger row = sender.tag;
// NSString *character = self.names[self.keys];
/* NSString *key = self.keys[indexPath.row];
NSArray *nameSection = self.names[key];
NSString *character = nameSection[indexPath];
*/
UIAlertView *alert = [[UIAlertView alloc]
initWithTitle:#"Request Notification."
message:[NSString
stringWithFormat:#"Friend Request Sent ."]
delegate:nil
cancelButtonTitle:#"OK"
otherButtonTitles:nil];
[alert show];
/* UIImage *buttonUpImage = [UIImage imageNamed:#"button.png"];
UIButton *button = [UIButton buttonWithType:UIButtonTypeCustom];
[cell.theSyncButton setImage:buttonUpImage forState:UIControlStateSelected];
[button setBackgroundImage:buttonUpImage
forState:UIControlStateNormal];
[button setTitle:#"Sent" forState:UIControlStateNormal];
[button sizeToFit];
*/
}
Now i require is to change background color and title to "sent" dynamically when user click on "Send" button in table view cell .How i can get this functionality ?

Answer 1

Try this,
- (UITableViewCell *)tableView:(UITableView *)tableView
cellForRowAtIndexPath:(NSIndexPath *)indexPath
{
....
UIButton *button;
if (cell.accessoryView == nil) {
...
button = [UIButton buttonWithType:UIButtonTypeCustom];
....
cell.accessoryView = button;
}
button.tag = indexPath.row;
...
}
in tappedButton:
- (void)tappedButton:(UIButton *)sender
{
NSInteger row = sender.tag;
UIImage *buttonUpImage = [UIImage imageNamed:#"button.png"];
[sender setBackgroundImage:buttonUpImage
forState:UIControlStateNormal];
[sender setTitle:#"Sent" forState:UIControlStateNormal];
NSIndexPath *indexPath = [NSIndexPath indexPathForRow:row inSection:0];
[self.tableView beginUpdates];
[self.tableView reloadRowsAtIndexPaths:[NSArray arrayWithObjects:indexPath, nil] withRowAnimation:UITableViewRowAnimationFade];
[self.tableView endUpdates];
}

Hi you can do following,
- (void)tappedButton:(UIButton *)sender
{
[sender setBackgroundColor:[UIColor grayColor]];
[sender setTitle:#"Sent" forState:UIControlStateNormal];
UIAlertView *alert = [[UIAlertView alloc]
initWithTitle:#"Request Notification."
message:[NSString
stringWithFormat:#"Friend Request Sent ."]
delegate:nil
cancelButtonTitle:#"OK"
otherButtonTitles:nil];
[alert show];
}

Answer 3

In your IBAction method tappedButton you get passed the button that the user tapped (the "sender" parameter.)
Change the background color and title of "sender"

Answer 4

[sender setBackgroundColor:[UIColor whiteColor]];
((UIButton *)sender).titleLabel.text = #"title";

Answer 5

Use selected state of button, in
- (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath
{
[button setTitle:#"Send" forState:UIControlStateNormal];
[button setBackgroundImage:original_image forState:UIControlStateNormal];
[button setTitle:#"Sent" forState:UIControlStateSelected];
[button setBackgroundImage:selected_image forState:UIControlStateSelected];
}
In tappedButton() function set sender to selected using [sender setSelected:YES]
The main reason for this approch is you can detect state of button using isSelected method.
