应用一个类轻松实现UITabBar and UINavigationController的界面跳转

相信大家在iOS界面开发中经常会用到UITabBar and UINavigationController

今天就给大家写个简单的方法实现这个功能

这里我会用到一个类和一个plist文件

首先我们可以先创建5个界面出来

这是我创建的5个界面

然后我们再创建一个plist文件

具体方法

这样就可以创建一个plist文件，然后我们在里面写入以下内容

接下来我们再创建一个叫做ConfigCenter的类

然后再ConfigCenter.h中定义一些属性和方法

@interface JConfigCenter :NSObject

@property (nonatomic,retain)NSMutableDictionary *config;

@property (nonatomic,copy)NSString *path;

+(id)getConfigWithKey:(NSString *)key;

+(id)getRootViewControllers;

@end

接下来我们再在ConfigCenter.m中实现

#import "JConfigCenter.h"

@implementation JConfigCenter

+(id)getRootViewControllers

{

return [selfgetConfigWithKey:kROOT_VIEW_CONTROLLERS];

}

+(id)getConfigWithKey:(NSString *)key

{

return [[selfgetConfig]objectForKey:key];

}

+(id)getConfig

{

staticNSDictionary *config;

if (!config) {

NSString * path = [[NSBundlemainBundle]pathForResource:@"config"ofType:@"plist"];

config = [NSDictionarydictionaryWithContentsOfFile:path];

}

return config;

}

@end

#import "JAppDelegate.h"

#import "JConfigCenter.h"

@implementation JAppDelegate

- (void)dealloc

{

[_windowrelease];

[superdealloc];

}

-(void)buildLayout

{

UITabBarController *tbc = [[UITabBarControlleralloc]init];

NSArray *controllers = [JConfigCentergetRootViewControllers];

for (NSString *controllerin controllers) {

UIViewController *vc = [[NSClassFromString(controller)alloc]init];

UINavigationController *nav = [[UINavigationControlleralloc]initWithRootViewController:vc];

[tbc addChildViewController:nav];

}

self.window.rootViewController = tbc;

}

#pragma mark -

#pragma mark JAppDelegate lifecycle

- (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions

{

self.window = [[[UIWindowalloc]initWithFrame:[[UIScreenmainScreen]bounds]]autorelease];

// Override point for customization after application launch.

self.window.backgroundColor = [UIColorwhiteColor];

[selfbuildLayout];

[self.windowmakeKeyAndVisible];

return YES;

}

@end

效果就如图：

希望这个方法可以帮到大家！

接下来还会继续实现各个界面的真正功能，希望大家能够支持！
