It could be probably a bug on iOS7. But the last button is not separated from the previous one
It seems that the initWithTitle:delegate:cancelButtonTitle:destructiveButtonTitle:otherButtonTitles: method is buggy and you shouldn't specify any cancel button here at all. Btw, it seems that a destructive button set in that method also won't work very well.
Instead of it you should:
["Action 1", "Action 2", "Close"]
or sheet.addButtonWithTitle("Close")
sheet.cancelButtonIndex = 2
Then everything will work as expected. On the iPad the button will be automatically hidden and on the iPhone it will be styled and placed in the proper way.
I found that adding a cancel button with an empty string after initialization works. The cancel button won't show up and the separator shows up.
[sheet addButtonWithTitle: @""];
[sheet setCancelButtonIndex: sheet.numberOfButtons - 1];
But this only works for iPad. On iPhone, an empty cancel button shows up, but I found a hacky workaround to make it work. In addition to the above, in willPresentActionSheet
add this code in:
NSInteger offset = 55;
CGRect superFrame = actionSheet.superview.frame;
superFrame.origin.y += offset;
[actionSheet.superview setFrame: superFrame];
// hide underlay that gets shifted with the superview
[(UIView*)[[actionSheet.superview subviews] objectAtIndex: 0] removeFromSuperview];
// create new underlay
CGRect underlayFrame = CGRectMake(0, -offset, superFrame.size.width, superFrame.size.height);
UIView* underlay = [[UIView alloc] initWithFrame: underlayFrame];
underlay.alpha = 0.0f;
[underlay setBackgroundColor: [UIColor colorWithWhite: 0.0f alpha: 0.4f]];
[actionSheet.superview insertSubview: underlay atIndex: 0];
// simulate fade in
[UIView animateWithDuration: 0.3f animations:^{
underlay.alpha = 1.0f;
}];
This shifts down the sheet to hide the cancel button off the screen
UIActionSheet *asAccounts = [[UIActionSheet alloc]
initWithTitle:Localized(@"select_an_account")
delegate:self
cancelButtonTitle:nil
destructiveButtonTitle:nil
otherButtonTitles: nil];
for (int i=0; i<[result count]; i++) {
ACAccount *acct = [result objectAtIndex:i];
[asAccounts addButtonWithTitle:[acct username]];
asAccounts.tag = i;
}
[asAccounts addButtonWithTitle:Localized(@"Cancel")];
asAccounts.cancelButtonIndex = result.count;
[asAccounts showInView:self.view];
The simplest fix is to pass @""
to the cancel button title instead of nil
during allocation.
UIActionSheet *actionSheet = [[UIActionSheet alloc]
initWithTitle:@"Title"
delegate:self
cancelButtonTitle:@"" // change is here
destructiveButtonTitle:nil
otherButtonTitles:@"First", @"Second", @"Third", @"Fourth", nil];
[actionSheet showInView:self.view];
If you have a cancel button, the last row will be shown. That is the temp fix I am using now. Do not know any solution if you do not want a cancel button to show
- (void)willPresentActionSheet:(UIActionSheet *)actionSheet {
if ([UIDevice currentDevice].systemVersion.floatValue < 8.0f) {
UIView *separator = [[UIView alloc] initWithFrame:CGRectMake(8, 88, actionSheet.frame.size.width - 16, 0.5)];
separator.backgroundColor = [UIColor colorWithRed:219.0f/255 green:219.0f/255 blue:223.0f/255 alpha:1];
[actionSheet addSubview:separator];
}
}
Every button has height 44. My actionSheet doesn't have title. And I wanted to add separator between second and third buttons. That's why I use number 88.
