主要是用到了一个第三方的类库，功能类似：UIView显示边栏的方法（二），具体的实现请参考附件。

AppDelegate.h

#import <UIKit/UIKit.h>

@class DDMenuController;
@class ViewController;
@interface AppDelegate : UIResponder <UIApplicationDelegate> {
	UINavigationController *navigationController;
}

@property (strong, nonatomic) UIWindow *window;
@property (strong, nonatomic) DDMenuController *menuController;
@property (strong, nonatomic) ViewController *viewController;

@end

AppDelegate.m

#import "AppDelegate.h"
#import "DDMenuController.h"
#import "ViewController.h"
#import "MeunViewController.h"

@implementation AppDelegate

@synthesize window = _window;
@synthesize viewController = _viewController;
@synthesize menuController = _menuController;

- (void)dealloc {
    [_window release];
    [_viewController release];
    [super dealloc];
}

- (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions {
	self.window = [[[UIWindow alloc] initWithFrame:[[UIScreen mainScreen] bounds]] autorelease];
    self.viewController = [[[ViewController alloc] initWithNibName:@"ViewController" bundle:nil] autorelease];
    UINavigationController *navController = [[UINavigationController alloc] initWithRootViewController:self.viewController];
    DDMenuController *rootController = [[DDMenuController alloc] initWithRootViewController:navController];
    _menuController = rootController;
    MeunViewController *leftController = [[MeunViewController alloc] init];
    rootController.leftViewController = leftController;
    self.window.rootViewController = rootController;
    
    self.window.backgroundColor = [UIColor whiteColor];
    [self.window makeKeyAndVisible];

    return YES;
}

@end

Toast是Android特有的一种提醒机制，本人认为这是一种很优秀的设计。但是通常我们在使用的时候会对其稍微地进行定制。比如设置Toast的背景（默认是黑色，略透明的），让整个应用程序有同样风格的Toast，个人认为是一个不错的选择，而且这样调用Toast比Toast默认的使用方式略显简单，所以记录起来方便以后使用。

public class ToastUtil {

	public static void show(Context context, String tip, boolean isLongTime) {

		Toast toast = new Toast(context);
		if (isLongTime) {

			toast.setDuration(Toast.LENGTH_LONG);
		} else {

			toast.setDuration(Toast.LENGTH_SHORT);
		}
		toast.setGravity(Gravity.CENTER, 0, 100);// 设置Toast的位置
		RelativeLayout rl = new RelativeLayout(context);
		rl.setLayoutParams(new LayoutParams(LayoutParams.WRAP_CONTENT,
				LayoutParams.WRAP_CONTENT));
		TextView textView = new TextView(context);
		textView.setTextColor(Color.WHITE);
		textView.setTextSize(16);
		textView.setText(tip);
		textView.setBackgroundResource(R.drawable.bg_toast);// 自定义的图片
		textView.setGravity(Gravity.CENTER);
		rl.setPadding(40, 0, 40, 0);// 设置Toast距离屏幕左右两边的距离
		rl.addView(textView);

		toast.setView(rl);
		toast.show();

	}

	public static void show(Context context, String tip) {

		ToastUtil.show(context, tip, false);
	}

}
