How to change space between UIBarButtonItems in UINavigationBar? - ios

Question

This is how it looks now:
This is how it is represented in Debug view Hierarchy:
And here is how I set it up in code:
func setupUserAndCartButtons() {
var rightBarButtonItems = [UIBarButtonItem]()
let cartBarButtonItem = UIBarButtonItem(image: DBCart.sharedCart().icon, style: .Plain, target: self, action: Selector("cartButtonTapped:"))
rightBarButtonItems.append(cartBarButtonItem)
let userIcon = UIImage(named: "icon-user")
let userBarButtonItem = UIBarButtonItem(image: userIcon, style: .Plain, target: self, action: Selector("userButtonTapped:"))
rightBarButtonItems.append(userBarButtonItem)
navigationItem.rightBarButtonItems = rightBarButtonItems
}
Hot to move them closer to each other without using custom view?

Answer 1

use imageInsets property of UIBarButtonItem
In Objective-C
[addContact setImageInsets:UIEdgeInsetsMake(0, -10,0, 0)];

Answer 2

Swift 4.1
buttonName.imageInsets = UIEdgeInsetsMake(0, 30, 0, 0)
This will move button to right side to other button.
Hope this will help someone

Answer 3

Add buttons using custom View:
//MARK:Customize Navigation Bar
func addButtonsToNavigationBar(){
let cartButton = UIButton.buttonWithType(UIButtonType.Custom) as! UIButton
cartButton.frame = CGRectMake(0,0,20,20)
cartButton.addTarget(self, action: "cartButtonTapped:", forControlEvents: .TouchUpInside)
cartButton.setImage(UIImage(named: DBCart.sharedCart().icon), forState: .Normal)
let cartBarButtonItem = UIBarButtonItem(customView: cartButton)
let userButton = UIButton.buttonWithType(UIButtonType.Custom) as! UIButton
userButton.frame = CGRectMake(0,0,20,20)
userButton.addTarget(self, action: "userButtonTapped:", forControlEvents: .TouchUpInside)
userButton.setImage(UIImage(named: "icon-user"), forState: .Normal)
let userBarButtonItem = UIBarButtonItem(customView: userButton)
self.navigationItem.rightBarButtonItems=[cartBarButtonItem,userBarButtonItem]
}

UIBarButtonSystemItemFixedSpace is used to adjust spacings of navigation bar items.
Example code:
- (void)setRightBarButtonItems {
UIBarButtonItem *addTaskButton =
[[UIBarButtonItem alloc] bk_initWithBarButtonSystemItem:UIBarButtonSystemItemAdd
handler:handler];
UIBarButtonItem *negativeSeperator = [[UIBarButtonItem alloc] initWithBarButtonSystemItem:UIBarButtonSystemItemFixedSpace target:nil action:nil];
if ([UIDevice isIOS7Plus]) {
negativeSeperator.width = -12;
} else {
negativeSeperator.width = -8;
}
UIBarButtonItem *separator = [[UIBarButtonItem alloc] initWithBarButtonSystemItem:UIBarButtonSystemItemFixedSpace target:nil action:nil];
separator.width = 50;
[self.navigationItem setRightBarButtonItems:#[addTaskButton, separator, [self filterButton]]];
}
