I am currently developing an application which needs an option to 'share' using multiple services; such as email, twitter.
To to this, I have a UIBarButtonItem
coded in and when touched, it triggers this:
UIActionSheet *sheet = [[UIActionSheet alloc]
initWithTitle:@""
delegate:self
cancelButtonTitle:nil
destructiveButtonTitle:nil
otherButtonTitles:nil];
[sheet addButtonWithTitle:@"Email"];
[sheet addButtonWithTitle:@"Tweet"];
[sheet addButtonWithTitle:@"Cancel"];
sheet.cancelButtonIndex = sheet.numberOfButtons-1;
[sheet showFromRect:self.view.bounds inView:self.view animated:YES];
[sheet release];
In conjunction with this to detect which button is selected:
clickedButtonAtIndex:(NSInteger)buttonIndex {
if (buttonIndex == actionSheet.cancelButtonIndex) { return; }
switch (buttonIndex) {
case 0:
{
[self emailThis];
break;
}
case 1:
{
[self tweetThis];
break;
}
}
This works a treat on the iPhone. But unfortunately it displays incorrectly on the iPad. It looks like it is trying to display the UIPopoverController
, but it is positioned center of the navbar with practically no height.
I have looked into using the UIPopoverController, but I cannot seem to find out how to use it with buttons. Is there anyway I can adapt the code above to properly display the buttons, as it's trying to already.
Many thanks,
Ryan
PS: I'm new to objective-c/iOS coding, so please be specific. Thank you 🙂
EDIT:
I have tried using:
[sheet showFromBarButtonItem:[self share] animated:YES];
But it doesn't work. Here is my code for the button:
UIBarButtonItem *share = [[UIBarButtonItem alloc]
initWithTitle:@"Share"
style:UIBarButtonItemStyleBordered
target:self
action:@selector(loadShare)];
self.navigationItem.rightBarButtonItem = share;
[share release];
Also here is the code in the .h file:
@interface DetailViewController : UIViewController <UITableViewDelegate, UITableViewDataSource> {
UIBarButtonItem *share;
}
@property (nonatomic, retain) IBOutlet UIBarButtonItem *share;
Here is the debug error:
Terminating app due to uncaught exception
'NSInvalidArgumentException', reason: '* -[__NSPlaceholderArray
initWithObjects:count:]: attempt to insert nil object from objects[0]'
