1、添加UIBarButtonItem:
1. - (void)viewDidLoad
2. {
3. [super viewDidLoad];
4.
5. UIBarButtonItem *leftButton = [[UIBarButtonItem alloc] initWithBarButtonSystemItem:UIBarButtonSystemItemAction target:self action:@selector(selectLeftAction:)];
6. self.navigationItem.leftBarButtonItem = leftButton;
7.
8. UIBarButtonItem *rightButton = [[UIBarButtonItem alloc] initWithBarButtonSystemItem:UIBarButtonSystemItemAdd target:self action:@selector(selectRightAction:)];
9. self.navigationItem.rightBarButtonItem = rightButton;<p class="p1">}</p>
以上都是以後要用到得item。。。含義很明顯，有了它們以後得item不再會亂用。。。
2、頁面間切換：
主頁面的設置：
- (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions
{
self.window = [[UIWindow alloc] initWithFrame:[[UIScreen mainScreen] bounds]];
self.window.backgroundColor = [UIColor whiteColor];
LZWelcomeViewController *rootController = [[LZWelcomeViewController alloc] init];
LZRootViewController *rootController1 = [[LZRootViewController alloc] init];
//之前錯誤之處：
//self.navController = [[UINavigationController alloc] initWithRootViewController:rootController];
//[self.navController setNavigationBarHidden:YES];
//[self.window addSubview:navController.view];
//welController = rootController;
//判斷是不是第一次使用此應用，不是第一次則跳過WelcomeView
if (![[NSUserDefaults standardUserDefaults] boolForKey:@"everLaunched"]) {
[[NSUserDefaults standardUserDefaults] setBool:YES forKey:@"everLaunched"];
[[NSUserDefaults standardUserDefaults] setBool:YES forKey:@"firstLaunch"];
}
else{ [[NSUserDefaults standardUserDefaults] setBool:NO forKey:@"firstLaunch"];
}
if ([[NSUserDefaults standardUserDefaults] boolForKey:@"firstLaunch"]){
self.window.rootViewController = rootController;
}else{
self.window.rootViewController = rootController1;
}
[self.window makeKeyAndVisible];
return YES;
}
