UIBarButtonSystemItemSave width unequal to UIBarButtonSystemItemCancel - ios

Question

I have seven UIBarButtonItems in a UIToolbar.
UIBarButtonSystemItemFixedSpace
UIBarButtonSystemItemCancel
UIBarButtonSystemItemFlexibleSpace
UIBarButton with custom text
UIBarButtonSystemItemFlexibleSpace
UIBarButtonSystemItemSave
UIBarButtonSystemItemFixedSpace
Everything is laying out as I would normally expect it to except for the UIBarButtonSystemItemSave item. It has an extra space next to it.
I added borders to each subview inside of the toolbar to try to figure out what was happening but still couldn't quite figure it out.
Maybe there was something happening with the order of the buttons so I switched the items around in order, but still couldn't figure it out.
Just in case it was something about the way I created the button, I changed the init option to UIBarButtonSystemItemCancel for both Save and Cancel.
Here's the code that I've been using.
- (UIToolbar *)headerToolbar {
if (!_headerToolbar) {
_headerToolbar = [[UIToolbar alloc] initWithFrame:self.headerToolbarFrame];
_headerToolbar.barTintColor = [[OVThemeManager shared] blueColor];
if (UIApplication.sharedApplication.userInterfaceLayoutDirection == UIUserInterfaceLayoutDirectionLeftToRight) {
_headerToolbar.items = #[[self fixedSpace:buttonBufferWidth],
self.cancelButton,
self.flexibleSpace,
self.titleButton,
self.flexibleSpace,
self.saveButton,
[self fixedSpace:buttonBufferWidth]];
} else {
_headerToolbar.items = #[[self fixedSpace:buttonBufferWidth],
self.saveButton,
self.flexibleSpace,
self.titleButton,
self.flexibleSpace,
self.cancelButton,
[self fixedSpace:buttonBufferWidth]];
}
[self borderSubviews:self.headerToolbar];
}
return _headerToolbar;
}
- (void)borderSubviews:(UIView *)superview {
superview.layer.borderWidth = 1.0f;
superview.layer.borderColor = [UIColor colorWithRed:0.001f *(float)(arc4random()%1000)
green:0.001f *(float)(arc4random()%1000)
blue:0.001f *(float)(arc4random()%1000)
alpha:1.0f].CGColor;
for (UIView *subview in superview.subviews) {
[self borderSubviews:subview];
}
}
- (CGRect)headerToolbarFrame {
CGRect frame = self.view.bounds;
frame.size.height = headerToolbarHeight;
return frame;
}
- (UIBarButtonItem *)saveButton {
if (!_saveButton) {
_saveButton = [[UIBarButtonItem alloc] initWithBarButtonSystemItem:UIBarButtonSystemItemSave
target:self
action:#selector(saveButtonTouched:)];
_saveButton.tintColor = [[OVThemeManager shared] blueColor];
}
return _saveButton;
}
- (UIBarButtonItem *)cancelButton {
if (!_cancelButton) {
_cancelButton = [[UIBarButtonItem alloc] initWithBarButtonSystemItem:UIBarButtonSystemItemCancel
target:self
action:#selector(cancelButtonTouched:)];
_cancelButton.tintColor = [[OVThemeManager shared] blueColor];
}
return _cancelButton;
}
- (UIBarButtonItem *)titleButton {
if (!_titleButton) {
_titleButton = [[UIBarButtonItem alloc] initWithTitle:#"Other button".localized
style:UIBarButtonItemStylePlain
target:nil
action:nil];
_titleButton.tintColor = [[OVThemeManager shared] blueColor];
}
return _titleButton;
}
- (UIBarButtonItem *)flexibleSpace {
return [[UIBarButtonItem alloc] initWithBarButtonSystemItem:UIBarButtonSystemItemFlexibleSpace
target:nil
action:nil];
}
- (UIBarButtonItem *)fixedSpace:(CGFloat)width {
UIBarButtonItem *fixedSpace = [[UIBarButtonItem alloc] initWithBarButtonSystemItem:UIBarButtonSystemItemFixedSpace
target:nil
action:nil];
fixedSpace.width = width;
return fixedSpace;
}
