IOS開發UI篇-NavigationController的控制器之間的跳轉

標籤：

 

一、如下

1> 第一個控制器的NavigationBar隱藏

2> 有按鈕，可以跳轉到下一個控制器，返回上一個控制器或者根控制器

二、思路代碼

思路：

　　1> 設定window的跟控制器為navigationController

　　2> 設定一個控制器的基類

 

 

主要代碼實現如下：

 AppDelegate.m

導航控制器類：GXNavController.h

#import <UIKit/UIKit.h>@interface GXNavController : UINavigationController@end

 

導航控制器類：GXNavController.m

基類：GXBaseViewController.h

 

#import <UIKit/UIKit.h>@interface GXBaseViewController : UIViewController@property (nonatomic,weak)UIButton *popBtn;@property (nonatomic,weak)UIButton *pushBtn;- (void)pop2Previous;- (void)push2Next;@end

  

基類:GXBaseViewController.m
