I have a UIPopoverController for data input with a 'Cancel' and 'Save' button. Both work fine on iOS6. On iOS7 the buttons show up but are not clickable (neither trigger their selectors)
cancelButtonItem = [[UIBarButtonItem alloc] initWithTitle:#"Cancel" style:UIBarButtonItemStyleBordered target:self action:#selector(cancel)];
saveButtonItem = [[UIBarButtonItem alloc] initWithTitle:#"Save" style:UIBarButtonItemStyleDone target:self action:#selector(save)];
if ([[UIDevice currentDevice] userInterfaceIdiom] == UIUserInterfaceIdiomPad) {
UIBarButtonItem *flexibleSpace = [[UIBarButtonItem alloc] initWithBarButtonSystemItem:UIBarButtonSystemItemFlexibleSpace target:nil action:nil];
NSMutableArray * arr = [NSMutableArray arrayWithObjects:cancelButtonItem,flexibleSpace, saveButtonItem, nil];
[_toolbar setItems:arr animated:YES];
} else {
//iPhone
self.navigationItem.leftBarButtonItem = cancelButtonItem;
self.navigationItem.rightBarButtonItem = saveButtonItem;
}
Any ideas?
This turned out to be a UIToolbar layered over a UINavigationController. The solution was to get rid of the UINavigationController.

Every time I load up the UIView that holds the UIToolbar below (which is attached to the keyboard), it turns black for a second until the view fully loads, and then turns back to the standard white color. I'm stumped as to why this keeps happening.
Here's how I'm forming the UIToolbar:
[self.answerField becomeFirstResponder];
UIToolbar *toolbar = [UIToolbar new];
UIBarButtonItem *sectionButton = [[UIBarButtonItem alloc] initWithTitle:#"§" style:UIBarButtonItemStylePlain target:nil
action:#selector(addSectionSymbol:)];
UIBarButtonItem *paraButton = [[UIBarButtonItem alloc] initWithTitle:#"¶" style:UIBarButtonItemStylePlain target:nil
action:#selector(addParaSymbol:)];
UIBarButtonItem *flexSpacing = [[UIBarButtonItem alloc] initWithBarButtonSystemItem:UIBarButtonSystemItemFlexibleSpace target:nil action:nil];
NSString *infoLabel = #"Select text to italicize. Always use italics.";
UIBarButtonItem *infoButton = [[UIBarButtonItem alloc] initWithTitle:infoLabel style:UIBarButtonItemStylePlain target:nil action:nil];
[infoButton setEnabled:NO];
[toolbar setItems:[NSArray arrayWithObjects:sectionButton, paraButton, flexSpacing, infoButton, nil]];
self.answerField.inputAccessoryView = toolbar;
[toolbar sizeToFit];
Any ideas?
I set two navigation bar buttons, and there is a space between it, how can I change this space to set buttons closer to each other?
I've tried to add third button with minus width, Here the code
self.editButton = [[UIBarButtonItem alloc] initWithImage:[UIImage imageNamed:#"Edit.png"] style:UIBarButtonItemStylePlain target:self action:#selector(editAction:)];
self.callButton = [[UIBarButtonItem alloc] initWithImage:[UIImage imageNamed:#"call_icon.png"] style:UIBarButtonItemStylePlain target:self action:#selector(editAction:)];
UIBarButtonItem *spacer = [[UIBarButtonItem alloc] initWithImage:[UIImage imageNamed:nil] style:UIBarButtonItemStylePlain target:self action:nil];
spacer.width = -30;
NSArray *buttons = #[self.editButton, spacer, self.callButton];
self.navigationItem.rightBarButtonItems = buttons;
But it is not working; Any suggessions?
UIBarButtonItem *negativeSpacer = [[UIBarButtonItem alloc]
initWithBarButtonSystemItem:UIBarButtonSystemItemFixedSpace
target:nil action:nil];
negativeSpacer.width = -16;// it was -6 in iOS 6
[self.navigationItem rightBarButtonItems:[NSArray arrayWithObjects:negativeSpacer, requriedButton/*this will be the button which u actually need*/, nil] animated:NO];
hope this will work for you...
You can create a UIBarButtonItem with the style UIBarButtonSystemItemFixedSpace and add it to the buttons array.
I use UIToolbar as inputAccessoryView of UITextView, there are some UIBarItems inside it.
self.toolbar = [[UIToolbar alloc] initWithFrame:CGRectMake(0, 0, 320, 44)];
NSMutableArray *items = [[NSMutableArray alloc] init];
UIBarButtonItem *bold = [[UIBarButtonItem alloc] initWithTitle:#"B" style:UIBarButtonItemStyleBordered target:self action:#selector(bold)];
UIBarButtonItem *italic = [[UIBarButtonItem alloc] initWithTitle:#"I" style:UIBarButtonItemStyleBordered target:self action:#selector(italic)];
UIBarButtonItem *underline = [[UIBarButtonItem alloc] initWithTitle:#"U" style:UIBarButtonItemStyleBordered target:self action:#selector(underline)];
[items addObject:underline];
[items addObject:italic];
[items addObject:bold];
self.toolbar.items = items;
[self.textView setInputAccessoryView:self.toolbar]
These items work OK, but when UIActivityViewController active, then dismiss in iOS6 simulator, these items are disappear, only blank toolbar display.
What's the reason? Please help!
I have 2 bar buttons on the tool bar , one is not working and the other is working. Some times when we touch the tip of the first bar button it will work, I think this has to be a problem with flexible space between them.
I couldn't find any possible solution, any help will be appreciated!
I'm pasting the code below
editbutton is the first button and mybutton is the second button
-(void) rightButtonToolbar:(UIBarButtonItem*)menuButton{
UIToolbar* toolbar = [[UIToolbar alloc] initWithFrame:CGRectMake(0, 0,TOOLBAR_WIDTH ,44)];
NSMutableArray *barButtons = [[NSMutableArray alloc]init];
UIBarButtonItem *flexiSpace = [[UIBarButtonItem alloc]initWithBarButtonSystemItem:UIBarButtonSystemItemFlexibleSpace target:nil action:nil];
[barButtons addObject:flexiSpace];
if (showEditButton)
{
NSLog(#"showeditbutton");
UIBarButtonItem *editButton = [[UIBarButtonItem alloc]initWithBarButtonSystemItem:UIBarButtonSystemItemEdit target:self action:#selector(editOffer)];
[barButtons addObject:editButton];
[editButton release];
}
UIBarButtonItem *myButton2 = [[UIBarButtonItem alloc] initWithTitle:#"Kopiren" style:UIBarButtonSystemItemAction target:self action:#selector(copyOffer)];
[barButtons addObject:myButton2];
if (menuButton != nil) {
menuButtonShown=YES;
[barButtons addObject:menuButton];
}
else {
menuButtonShown=NO;
}
[toolbar setItems:barButtons animated:YES];
UIBarButtonItem *rightBarButton = [[UIBarButtonItem alloc]initWithCustomView:toolbar];
[self.navigationItem setRightBarButtonItem:rightBarButton animated:YES];
[barButtons release];
[flexiSpace release];
[rightBarButton release];
[toolbar release];
[myButton2 release];
}
I've added a UIToolBar with a UIBarButtonItem as inputAccessoryView for a UITextView. It works fine but the UIBarButtonItem is touchable outside it's frame, perhaps 50 pixels outside to the right. It's no big deal but it annoys me. Anyone know why?
This is my code (ARC):
UIToolbar *toolBar = [[UIToolbar alloc] initWithFrame:CGRectMake(0, self.view.bounds.size.height, 320, 44)];
toolBar.barStyle = UIBarStyleBlack;
toolBar.translucent = YES;
UIBarButtonItem *doneButton = [[UIBarButtonItem alloc] initWithBarButtonSystemItem:UIBarButtonSystemItemDone target:self action:#selector(doneWriting:)];
[toolBar setItems:[NSArray arrayWithObjects:doneButton, nil]];
self.messageTextView.inputAccessoryView = toolBar;
In iOS 6 it seems to behave as expected.
Nice tip: If you want the button to appear on the right instead of the left, use one of these:
UIBarButtonItem *flexibleSpace = [[UIBarButtonItem alloc] initWithBarButtonSystemItem:UIBarButtonSystemItemFlexibleSpace target:self action:nil];
Then initialise the toolbar with:
[toolBar setItems:[NSArray arrayWithObjects:flexibleSpace, doneButton, nil]];
The toolbar seems to expand the active area of the buttons beyond their bounds if there are no other nearby buttons in the toolbar. Apple engineers must think it is better to try to guess where the user intended to press rather than not react at all.
I hope it helps you...
UIToolbar* keyboardDoneButtonView = [[UIToolbar alloc] init];
[keyboardDoneButtonView sizeToFit];
UIBarButtonItem* PrevButton = [[UIBarButtonItem alloc] initWithBarButtonSystemItem:105 target:nil action:nil]; //<
UIBarButtonItem* NextButton = [[UIBarButtonItem alloc] initWithBarButtonSystemItem:106 target:nil action:nil]; //>
UIBarButtonItem* doneButton = [[UIBarButtonItem alloc] initWithTitle:#"Done" style:UIBarButtonItemStyleBordered target:self action:#selector(doneClicked:)];
UIBarButtonItem* flexSpace = [[UIBarButtonItem alloc] initWithBarButtonSystemItem:UIBarButtonSystemItemFlexibleSpace target:nil action:nil];
UIBarButtonItem *fake = [[UIBarButtonItem alloc] initWithTitle:#"" style:UIBarButtonItemStylePlain target:nil action:nil] ;
[keyboardDoneButtonView setItems:[NSArray arrayWithObjects: PrevButton,fake, NextButton,fake,flexSpace,fake,doneButton,nil] animated:YES];
Use Fake Item to get exact pinch location on Button...
