I'm playing with Navigation Bar Buttons I need a button from right edge with 0 space, after google search i found below code
self.filterButton = [[UIButton alloc] initWithFrame:CGRectMake(0, 0, 80, 45)];
[self.filterButton setBackgroundColor:[UIColor redColor]];
UIImage *buttnImage=[UIImage imageNamed:@"chemistry-filter"];
[self.filterButton setImage:buttnImage forState:UIControlStateNormal];
[self.filterButton addTarget:self action:@selector(filterAction:) forControlEvents:UIControlEventTouchUpInside];
UIBarButtonItem *btn2 = [[UIBarButtonItem alloc] initWithCustomView:self.filterButton];
UIBarButtonItem *negativeSpacer = [[UIBarButtonItem alloc] initWithBarButtonSystemItem:UIBarButtonSystemItemFixedSpace target:nil action:nil];
negativeSpacer.width = -25;
[self.navigationItem setRightBarButtonItems:[NSArray arrayWithObjects:negativeSpacer,btn2, nil] animated:YES];
But unfortunatly in iOS 13 negativeSpacer not working. can anybody suggest me solutions.
Let's try this easy way, Let's define the width of space BarButtonItem to be width of self.view.frame.size.width - width of the button
.
self.filterButton = [[UIButton alloc] initWithFrame:CGRectMake(0, 0, 80, 45)];
[self.filterButton setBackgroundColor:[UIColor redColor]];
UIImage *buttnImage=[UIImage imageNamed:@"chemistry-filter"];
[self.filterButton setImage:buttnImage forState:UIControlStateNormal];
[self.filterButton addTarget:self action:@selector(filterAction:)
forControlEvents:UIControlEventTouchUpInside];
UIBarButtonItem *btn2 = [[UIBarButtonItem alloc]
initWithCustomView:self.filterButton];
UIBarButtonItem *negativeSpacer = [[UIBarButtonItem alloc]
initWithBarButtonSystemItem:UIBarButtonSystemItemFixedSpace target:nil
action:nil];
negativeSpacer.width = self.view.frame.size.width - 45; // As 45 is the frame width of your filter button
[self.navigationItem setRightBarButtonItems:[NSArray
arrayWithObjects:negativeSpacer,btn2, nil] animated:YES];
Hope this helps!
