Tabbar switching between packages of different controllers (custom navigation + custom uiviewcontroler+ system comes with tabbar+ custom Tabbarcontroller)

First, the environment for an app is very important. Both the basic functionality and the performance of later optimizations are considered.

Now many applications are not just the controller of the system, because of the complex requirements, it is necessary to customize multi-controller to manage.

Create a new Basicnavigationviewcontroller, inherit Uinavigationcontroller

Here to achieve the navigation appearance, methods and so on.

The sample code is as follows:

Then customize a basictabbarviewcontroller, inherit Uitabbarcontroller

The code is as follows:

#import <UIKit/UIKit.h>
@class Basicnavgationviewcontroller;


@interface Basictabbarviewcontroller:uitabbarcontroller

@property (nonatomic, strong) Basicnavgationviewcontroller *homenavgationcontroller;
@property (nonatomic, strong) Basicnavgationviewcontroller *minenavgationcontroller;
@property (nonatomic, strong) Basicnavgationviewcontroller *morenavgationcontroller;

@end

#import "RootViewController.h"
#import "HomeViewController.h"
#import "MineViewController.h"
#import "MoreViewController.h"
#import "BasicNavgationViewController.h"
#define Dmnavgationcolor Dmrgb (65, 109, 218)//Navigation color

#define DMRGB (R, G, b) [Uicolor colorwithred: (r)/255.f Green: (g)/255.F Blue: (b)/255.f ALPHA:1.F]

#define Dmtableviewgraycolor Dmrgb (245, 245, 249)//Bright Grey (tableview background)
@interface Basictabbarviewcontroller () <UITabBarControllerDelegate>

@end

return YES;

}

Finally: Customize a Rootviewcontroller, inherit the Uiviewcontroller, and inherit it from the controller creation later.
