Implement page jump with UIButton (appdelegate +navigationviewcontroller)

1.appdelegate.h

Define a Uinavigationcontroller

#import <UIKit/UIKit.h>

#import "MainViewController.h"

@interface appdelegate:uiresponder <uiapplicationdelegate>

@property (Strong, nonatomic) uiwindow *window;

@property (Strong, nonatomic) uinavigationcontroller *navigationcotroller;

@end

2.appdelegate.m

#import "AppDelegate.h"

@interface appdelegate ()

@end

@implementation appdelegate

-(BOOL) application: (uiapplication *) application didfinishlaunchingwithoptions: (nsdictionary *) launchoptions {

self. Window = [[uiwindow alloc]initwithframe: [[uiscreen mainscreen]bounds]];/ /Instantiate window

Mainviewcontroller *mainviewcontroller = [[Mainviewcontroller alloc]init];// Instantiating a Mainview controller

//Put the Mainview controller in the Navigationcontroller method to make it a root controller

_navigationcotroller = [[uinavigationcontroller alloc] initwithrootviewcontroller: Mainviewcontroller];

[_window addsubview: _navigationcotroller. View ofthe navigation controller loaded in the view];//window

[self. Window makekeyandvisible];//view visible

return YES;

}

3.mainviewcontroller.m

Set the button's page, the button trigger method, call Appdelegate in the navigation controller's Pushviewcontroller method, implement the page jump (automatically generate a return to the health of the page).

Method of button triggering:

[_logonbtn addTarget:self Action:@selector(loginclick:) forcontrolevents: UIControlEventTouchUpInside];

Page Jump:

-(void) Loginclick: (ID) sender{

Logonviewcontroller *logonview = [[Logonviewcontroller alloc]init];

appdelegate *mydelete = [[uiapplication sharedapplication]delegate];

[Mydelete. Navigationcotroller pushviewcontroller:logonview animated:YES];

}
