ios模态视图上到导航控制器怎么弄出来

Answer 1

你说的是导航栏吧，可以考虑在事件方法中添加，响应时将其添加到跟视图，你说的遮挡问题，要是只有一个视图的话，可以改下坐标试试，最好不要这样子，我记得有两行代码可以解决，然后在xib文件中拖控件，这样不会遮挡上一视图，那两行代码我忘了，你去开发者中心或者开元中国去看看吧

1.首先创建一个KCTabBarViewController继承于UITabBarController（代码是默认生成的，不再贴出来）。
2.其次创建两个子视图，在这两个子视图控制器中设置对应的名称、图标等信息。

#import "KCWebChatViewController.h"

@interface KCWebChatViewController ()

@end

@implementation KCWebChatViewController

- (void)viewDidLoad {
[super viewDidLoad];

self.view.backgroundColor=[UIColor redColor];

//设置视图控制器标题
self.title=@"Chat";

//注意通过tabBarController或者parentViewController可以得到其俯视图控制器（也就是KCTabBarViewController）
NSLog(@"%i",self.tabBarController==self.parentViewController);//对于当前应用二者相等

//设置图标、标题(tabBarItem是显示在tabBar上的标签)
self.tabBarItem.title=@"Web Chat";//注意如果这个标题不设置默认在页签上显示视图控制器标题
self.tabBarItem.image=[UIImage imageNamed:@"tabbar_mainframe.png"];//默认图片
self.tabBarItem.selectedImage=[UIImage imageNamed:@"tabbar_mainframeHL.png"];//选中图片

//图标右上角内容
self.tabBarItem.badgeValue=@"5";

}
@end

#import "KCContactViewController.h"

@interface KCContactViewController ()

@end

@implementation KCContactViewController

- (void)viewDidLoad {
[super viewDidLoad];
self.view.backgroundColor=[UIColor yellowColor];

self.tabBarItem.title=@"Contact";
self.tabBarItem.image=[UIImage imageNamed:@"tabbar_contacts.png"];
self.tabBarItem.selectedImage=[UIImage imageNamed:@"tabbar_contactsHL.png"];

}

@end

3.在应用程序启动后设置Tab bar视图控制器的子视图，同时将Tab bar视图控制器作为window的根控制器。

#import "AppDelegate.h"
#import "KCTabBarViewController.h"
#import "KCWebChatViewController.h"
#import "KCContactViewController.h"

@interface AppDelegate ()

@end

@implementation AppDelegate

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

_window=[[UIWindow alloc]initWithFrame:[UIScreen mainScreen].bounds];

KCTabBarViewController *tabBarController=[[KCTabBarViewController alloc]init];

KCWebChatViewController *webChatController=[[KCWebChatViewController alloc]init];
KCContactViewController *contactController=[[KCContactViewController alloc]init];
tabBarController.viewControllers=@[webChatController,contactController];
//注意默认情况下UITabBarController在加载子视图时是懒加载的，所以这里调用一次contactController，否则在第一次展示时只有第一个控制器tab图标，contactController的tab图标不会显示
for (UIViewController *controller in tabBarController.viewControllers) {
UIViewController *view= controller.view;
}

_window.rootViewController=tabBarController;
[_window makeKeyAndVisible];

return YES;
}

- (void)applicationWillResignActive:(UIApplication *)application {
// Sent when the application is about to move from active to inactive state. This can occur for certain types of temporary interruptions (such as an incoming phone call or SMS message) or when the user quits the application and it begins the transition to the background state.
// Use this method to pause ongoing tasks, disable timers, and throttle down OpenGL ES frame rates. Games should use this method to pause the game.
}

- (void)applicationDidEnterBackground:(UIApplication *)application {
// Use this method to release shared resources, save user data, invalidate timers, and store enough application state information to restore your application to its current state in case it is terminated later.
// If your application supports background execution, this method is called instead of applicationWillTerminate: when the user quits.
}

- (void)applicationWillEnterForeground:(UIApplication *)application {
// Called as part of the transition from the background to the inactive state; here you can undo many of the changes made on entering the background.
}

- (void)applicationDidBecomeActive:(UIApplication *)application {
// Restart any tasks that were paused (or not yet started) while the application was inactive. If the application was previously in the background, optionally refresh the user interface.
}

- (void)applicationWillTerminate:(UIApplication *)application {
// Called when the application is about to terminate. Save data if appropriate. See also applicationDidEnterBackground:.
}
