I have a tableView and I create a Button on one cell.
UIButton *deleteGroupButton = [UIButton buttonWithType:UIButtonTypeCustom];
[deleteGroupButton setFrame:CGRectMake(218, 12, 40, 60)];
[deleteGroupButton addTarget:self action:@selector(deleteGroupButtonClicked:) forControlEvents:UIControlEventTouchUpInside];
When I click to button, an Exception occur with that message:
"Terminating app due to uncaught exception 'NSInvalidArgumentException', reason: '-[Group deleteGroup:]: unrecognized selector sent to instance 0x5a8afc0' "
And that is my deleteGroupButtonClicked method
- (void) deleteGroupButtonClicked: (id) sender {
Groups *tmpGroups = [[Group alloc] init];
NSInteger tmp = appDelegate.selectedGroupId;
[tmpGroups deleteGroup:tmp];
[tmpGroups release];
}
You have something slightly odd in your deleteGroupButtonClicked: method,
You have a object of class Groups
but you are alloc'ing an object of class Group
. I am guessing Groups
is a collection of Group
objects. In which case a deleteGroup:
method would only exist in the Groups
class.
Just replace your deleteGroupButtonClicked method with the following:
- (void) deleteGroupButtonClicked: (id) sender
{
Groups *tmpGroups = [[Groups alloc] init];
NSInteger tmp = appDelegate.selectedGroupId;
[tmpGroups deleteGroup:tmp];
[tmpGroups release];
}
