Two icons in the title. When you click the icon, the page will jump to the new house (similar to the area near the new House of anjuke ).

 

When I first came in:

When you click the button on the right:

RootViewController. h

#import <UIKit/UIKit.h>@interface RootViewController : UIViewController{    UIButton * leftButton;    UIButton * rightButton;    UIViewController * firstController;    UIViewController * secondController;}@end

 

 

RootViewController. m

-(Void) viewDidLoad {[super viewDidLoad]; // Do any additional setup after loading the view. // initialize the top button [self creatHeadView]; // initialize the background image [self initBackView];} # pragma-mark-functions-(void) initBackView {firstController = [[UIViewController alloc] init]; firstController. view. backgroundColor = [UIColor redColor]; [self. view addSubview: firstController. view]; secondController = [[UIViewController alloc] init]; secondController. view. backgroundColor = [UIColor blueColor];}-(void) creatHeadView {UIView * headView = [[UIView alloc] initWithFrame: CGRectMake (0, 0,100, 30)]; // The left button leftButton = [UIButton buttonWithType: UIButtonTypeCustom]; leftButton. frame = CGRectMake (0, 0, 50, 30); leftButton. tag= 201; leftButton. enabled = NO; [leftButton setImage: [UIImage imageNamed: @ "left"] forState: UIControlStateNormal]; [leftButton addTarget: self action: @ selector (doClickHeadActions :) forControlEvents: role]; [headView addSubview: leftButton]; // the right button rightButton = [UIButton buttonWithType: UIButtonTypeCustom]; rightButton. frame = CGRectMake (50, 0, 50, 30); rightButton. tag = 301; [rightButton setImage: [UIImage imageNamed: @ "right"] forState: UIControlStateNormal]; [rightButton addTarget: self action: @ selector (doClickHeadActions :) forControlEvents: role]; [headView addSubview: rightButton]; self. navigationItem. titleView = headView;} # pragma-mark-doClickActions-(void) doClickHeadActions :( UIButton *) btn {if (btn. tag = 201) {[secondController dismissViewControllerAnimated: NO completion: nil]; [btn setImage: [UIImage imageNamed: @ "leftselect"] forState: UIControlStateNormal]; btn. enabled = NO; [rightButton setImage: [UIImage imageNamed: @ "right"] forState: UIControlStateNormal]; rightButton. enabled = YES;} else if (btn. tag = 301) {[firstController presentViewController: secondController animated: NO completion: nil]; [btn setImage: [UIImage imageNamed: @ "rightselect"] forState: UIControlStateNormal]; btn. enabled = NO; [leftButton setImage: [UIImage imageNamed: @ "left"] forState: UIControlStateNormal]; leftButton. enabled = YES ;}}
