delegate method throws runtime "unrecognized selector" error when switching back from one UIViewCont
- by chimgrrl
Ok, I've spend like half day on this and it's killing me.
So I've got 3 view controllers transitioning from one another, something like this:
I call the UploadDecisionViewController after destroying the previous View Controller:
[self dismissModalViewControllerAnimated:YES];
[self performSelector:@selector(showUDModalView) withObject:nil afterDelay:0.5];
In my showUDModalView method:
- (void)showUDModalView
{
UploadDecisionViewController *udcontroller = [[UploadDecisionViewController alloc] initWithNibName:@"UploadDecisionViewController" bundle:nil];
udcontroller.delegate = self;
[self presentModalViewController:udcontroller animated:YES];
[udcontroller release];
}
The UploadDecisionViewController shows up no problem. The UploadDecisionViewController has a button, which when clicked I want it to transition to the FileUploadViewController. I setup a UploadDecisionDelegate, threw a method in there to handle the button clicking:
Inside UploadDecisionDelegate protocol (UploadDecisionViewController.h):
@protocol UploadDecisionDelegate
//let UOnliveViewController know that a button was selected
- (void)UploadDecisionViewController:(UploadDecisionViewController *)controller madeChoice:(NSString *)whichDirection;
@end
Then inside my IBAction method when the button is clicked, I have this:
- (IBAction)decisionSelected:(id)sender
{
[delegate UploadDecisionViewController:self madeChoice:@"upload"];//crashing at this line
}
When I run this, at this line above it is throwing a runtime exception:
2010-06-09 12:48:59.561 UOnlive[4735:207] *** -[UIView UploadDecisionViewController:madeChoice:]: unrecognized selector sent to instance 0x3b65420

)
Let me throw in the delegate method implemented also:
- (void)UploadDecisionViewController:(UploadDecisionViewController *)controller madeChoice:(NSString *)whichDirection
{
NSLog(@"it got to here 245");
[self dismissModalViewControllerAnimated:YES];
if (yesOrNo) {
//open up the FileUploadViewController and proceed to upload
[self performSelector:@selector(showFUModalView) withObject:nil afterDelay:0.5];
}
}
Can someone tell me what the heck is going on? Thanks a bunch for the help...
