iOS 7中UINavigationbar下方的UISegmentedControl
如何将iOS 7中UINavigationbar下方的UISegmentedControl,ios,uinavigationbar,uisegmentedcontrol,Ios,Uinavigationbar,Uisegmentedcontrol,如何将UISegmentedControl作为其下方UINavigationBar的一部分？它是连接到UINavigationBar还是作为子视图添加到UINavigationController的视图控制器中的一个完整的单独视图。看起来它是UINavigationBar的一部分，因为该条下方有一个阴影 是在导航栏中显示搜索栏及其范围栏的方法 只要在显示自定义标题时隐藏搜索栏就可以了。有很多方法可以满足您的要求。当然，最简单的方法是在interface builder中创建它，但我认为这不是您想
UISegmentedControlUINavigationBarUINavigationBarUINavigationControllerUINavigationBar只要在显示自定义标题时隐藏搜索栏就可以了。有很多方法可以满足您的要求。当然，最简单的方法是在interface builder中创建它，但我认为这不是您想要的。我创建了一个你在上面发布的图像的示例。这并不完全相同，但您可以使用众多的属性来获得所需的外观和感觉 在ViewController.h中
#import <UIKit/UIKit.h>
@interface ViewController : UIViewController <UITableViewDataSource, UITableViewDelegate, UISearchBarDelegate>
@end
这是一个简单的效果
首先，在工具栏中放置一个段。将此工具栏放在导航栏的正下方。将工具栏的委托设置为视图控制器，并在

return self;

if (self) {
[self initialize];
}
return self;
}
- (void)initialize {
// Set tittle position for top
[self setTitleVerticalPositionAdjustment:-(MyNavigationBarHeightIncrease) forBarMetrics:UIBarMetricsDefault];
}
- (CGSize)sizeThatFits:(CGSize)size {
// Increase NavBar size
CGSize amendedSize = [super sizeThatFits:size];
amendedSize.height += MyNavigationBarHeightIncrease;
return amendedSize;
}
- (void)layoutSubviews {
// Set buttons position for top
[super layoutSubviews];
NSArray *classNamesToReposition = @[@"UINavigationButton"];
for (UIView *view in [self subviews]) {
if ([classNamesToReposition containsObject:NSStringFromClass([view class])]) {
CGRect frame = [view frame];
frame.origin.y -= MyNavigationBarHeightIncrease;
[view setFrame:frame];
}
}
}
- (void)didAddSubview:(UIView *)subview
{
// Set segmented position
[super didAddSubview:subview];
if ([subview isKindOfClass:[UISegmentedControl class]])
{
CGRect frame = subview.frame;
frame.origin.y += MyNavigationBarHeightIncrease;
subview.frame = frame;
}
}
@end
3-在导航栏中添加您的UISegmentedControl
4-跑步和娱乐 ->别忘了把两种颜色都涂上
搜索来源： 现在要去除发际线。“发际线”是一个UIImageView，它是导航栏的子视图。您可以找到它并将其设置为隐藏。例如，这就是苹果在其原生日历应用程序和商店应用程序中所做的。记住在当前视图消失时显示它。如果您稍微玩一下Apple应用程序，您会看到发际线被设置为“在视图上隐藏”“将显示：”，并设置为“在视图中显示”“消失：” 另一种方法是查找发际线并将其移动到添加的工具栏下方。这是我想到的

bView.bounds.size.height < 2) {
self.navHairline = (UIImageView *)bView;
