I have a button I have created programmatically within a view controller. Once the button is pressed I want it to to use a method to create the popover programmatically.
The button which is created in the ViewDidLoad in my view controller.m
UIView *moreFundInfoView = [[UIView alloc] initWithFrame:CGRectMake(0, 0, 540, 620)];
[self.view addSubview:moreFundInfoView];
[moreFundInfoView setBackgroundColor:[UIColor RMBColor:@"b"]];
btnContact = [UIButton buttonWithType:(UIButtonTypeRoundedRect)];
[btnContact setFrame:CGRectMake(390, 575, contactButton.width, contactButton.height)];
btnContact.hidden = NO;
[btnContact setTitle:@"Contact" forState:(UIControlStateNormal)];
[moreFundInfoView addSubview:btnContact];
[btnContact addTarget:self action:@selector(showContactDetails:) forControlEvents:UIControlEventTouchUpInside];
Then I have the method I use when the button is pressed.
-(void) showContactDetails: (id) sender
{
UIViewController *popoverContent = [[UIViewController alloc]init];
UIView *popoverView = [[UIView alloc]initWithFrame:CGRectMake(0, 0, 200, 300)];
[popoverView setBackgroundColor:[UIColor RMBColor:@"b"]];
popoverContent.view = popoverView;
popoverContent.contentSizeForViewInPopover = CGSizeMake(200, 300);
UIPopoverController *contactPopover =[[UIPopoverController alloc] initWithContentViewController:popoverContent];
[contactPopover presentPopoverFromRect:btnContact.frame inView:self.view permittedArrowDirections:UIPopoverArrowDirectionUp animated:YES ];
[contactPopover setDelegate:self];
}
What am I missing here? Cause it runs fine, but as soon as I click the button the app crashes. I think it is a delegate issue, but I am not sure. Any advice would be appreciated.
I think this code will help you. You are certainly missing delegate methods
ViewController *viewController = [[ViewController alloc] initWithNibName:@"ViewController" bundle:nil];
UINavigationController *navigationController = [[UINavigationController alloc] initWithRootViewController:viewController];
UIPopoverController *popover = [[UIPopoverController alloc] initWithContentViewController:navigationController];
popover.delegate = self;
popover.popoverContentSize = CGSizeMake(644, 425); //your custom size.
[popover presentPopoverFromRect:button.frame inView:self.view permittedArrowDirections: UIPopoverArrowDirectionLeft | UIPopoverArrowDirectionUp animated:YES];
Just make sure you are not forgetting UIPopover Delegate methods or else application will definitely crash. It is mandatory.
