iOS 11 navigationItem.titleView Width Not Set

Question

Seeing a behavior on iOS11 with a navigationItem.titleView where the width of the titleView is not the full width of the screen.

I have a custom view that I set as t

Answer 1

Using @falkon's answer here's the code:

Add this code to the view that is used as titleView

override var intrinsicContentSize: CGSize {
    return UILayoutFittingExpandedSize
} 

Answer 2

The most important is that you need overwrite customTitleView as your titleView:

self.navigationItem.titleView = [self titleView];

#pragma mark - getter

- (UIView *)titleView {
    UIView *navTitleView = [HFCalenderTitleView new];
    navTitleView.frame = CGRectMake(0.0, 0.0, HorizontalFrom750(200.0), 44.0);

    [navTitleView addSubview:self.titleLabel];
    [self.titleLabel mas_makeConstraints:^(MASConstraintMaker *make) {
        make.center.equalTo(navTitleView);
    }];

    CGFloat btnWidth = 30.0;
    [navTitleView addSubview:self.previousButton];
    self.previousButton.imageEdgeInsets = UIEdgeInsetsMake(0.0, 0.0, 0.0, 15.0);
    [self.previousButton mas_makeConstraints:^(MASConstraintMaker *make) {
        make.left.equalTo(navTitleView);
        make.top.bottom.equalTo(navTitleView);
        make.width.equalTo(@(btnWidth));
    }];
    [navTitleView addSubview:self.nextBtn];
    self.nextBtn.imageEdgeInsets = UIEdgeInsetsMake(0.0, 15.0, 0.0, 0.0);
    [self.nextBtn mas_makeConstraints:^(MASConstraintMaker *make) {
        make.right.equalTo(navTitleView);
        make.top.bottom.equalTo(navTitleView);
        make.width.equalTo(@(btnWidth));
    }];

    return navTitleView;
}
#pragma mark - customTitleView

#import "HFCalenderTitleView.h"
@implementation HFCalenderTitleView
- (CGSize)intrinsicContentSize{
    return CGSizeMake(HorizontalFrom750(200.0), 40); // the target size
}
