类似这样的导航栏 用WKBarButtonUtil那个框架:
- (void)initNav
{//必要的设置, 如果没有设置可能导致内容显示不正常// self.edgesForExtendedLayout = UIRectEdgeNone;UIButton *btn = [UIButton buttonWithType:UIButtonTypeCustom];[btn setTitleColor:[UIColor blackColor] forState:UIControlStateNormal];btn.frame = CGRectMake(10, 35/2.0f, 60, 40);btn.imageEdgeInsets = UIEdgeInsetsMake(0, -30, 0, 0);btn.titleEdgeInsets = UIEdgeInsetsMake(0, 0, 0, -30);btn.titleLabel.textAlignment = NSTextAlignmentLeft;btn.mj_y = _segment.mj_y-7;btn.width = 100;[btn setTitle:@"杭州" forState:UIControlStateNormal];[btn setImage:[UIImage imageNamed:@"rightRow_home"] forState:UIControlStateNormal];CGSize titleSize = self.cBtnLeft.titleLabel.bounds.size;CGSize imageSize = self.cBtnLeft.imageView.bounds.size;//文字左移btn.titleEdgeInsets = UIEdgeInsetsMake(0.0, -imageSize.width-10, 0.0, 60);// UIEdgeInsetsMake(<#CGFloat top#>, <#CGFloat left#>, <#CGFloat bottom#>, <#CGFloat right#>)//图片右移btn.imageEdgeInsets = UIEdgeInsetsMake(0.0, titleSize.width, 0.0, -titleSize.width);btn.titleLabel.font = Font(12.0);self.navigationItem.leftBarButtonItem = [[UIBarButtonItem alloc]initWithCustomView:btn];self.navigationItem.rightBarButtonItem = [WKBarButtonUtil barButtonWithImage:Image(@"rightRow_home") target:self action:@selector(navRightPressed)];[btn addTarget:self action:@selector(navLeftPressed) forControlEvents:UIControlEventTouchUpInside];self.segment = [[HMSegmentedControl alloc] initWithSectionTitles:@[@"优选",@"咨询"]];_segment.frame =CGRectMake(0, 20, 120, 44);_segment.verticalDividerWidth = 10;_segment.selectionIndicatorLocation = HMSegmentedControlSelectionIndicatorLocationDown;NSLog(@"segment.frame%@",NSStringFromCGRect(_segment.frame));NSLog(@"selectionIndicatorHeight%f",_segment.selectionIndicatorHeight);_segment.selectionIndicatorHeight = 2.0f;_segment.selectionIndicatorLocation = HMSegmentedControlSelectionIndicatorLocationDown;_segment.selectionIndicatorColor = [UIColor redColor];_segment.titleTextAttributes = @{NSFontAttributeName:[UIFont systemFontOfSize:14],NSForegroundColorAttributeName:[UIColor blackColor]};_segment.selectedTitleTextAttributes = @{NSFontAttributeName:[UIFont systemFontOfSize:15],NSForegroundColorAttributeName:[UIColor redColor]};_segment.autoresizingMask = UIViewAutoresizingFlexibleRightMargin | UIViewAutoresizingFlexibleWidth;[_segment addTarget:self action:@selector(segmentedControlChangedValue:) forControlEvents:UIControlEventValueChanged];self.navigationItem.titleView = self.segment;UIView *line = [[UIView alloc] init];line.frame = (CGRect){0,K_NAV_HEIGHT-1,K_SCREEN_WIDTH,1};line.backgroundColor = COLORE_BACKGROUNDCOLOR_LIGHTGRAY;//试验居中CGRect leftViewbounds = self.navigationItem.leftBarButtonItem.customView.bounds;CGRect rightViewbounds = self.navigationItem.rightBarButtonItem.customView.bounds;CGRect frame;CGFloat maxWidth = leftViewbounds.size.width > rightViewbounds.size.width ? leftViewbounds.size.width : rightViewbounds.size.width;maxWidth += 15;//leftview 左右都有间隙，左边是5像素，右边是8像素，加2个像素的阀值 5 ＋ 8 ＋ 2frame = _segment.frame;frame.size.width = K_SCREEN_WIDTH - maxWidth * 2;self.navigationItem.titleView.frame = frame;frame = _segment.frame;frame.size.width = K_SCREEN_WIDTH - maxWidth * 2;_segment.frame = frame;}- (void)createUI
{}
- (void)navLeftPressed
{NSLog(@"clickleft");
}- (void)navRightPressed
{NSLog(@"clickRight");
}
- (void)navRightPressed:(UIButton *)sender
{}
- (void)segmentedControlChangedValue:(HMSegmentedControl *)sender
{}
缺点:HMSegment下面的线不能如设计稿缩短,暂时先这样待优化.或自己写或找博客
简易修改那条红线可参考
