[IOS]本地通知

[IOS]本地通知
Demo：http://download.csdn.net/detail/u012881779/9136957

本地通知一般用于闹钟、待办事项、延迟响应等定时提醒或操作，能有效的减轻服务端压力。

和很多第三方的推送工具一样，只在AppDelegate.m中就能完成操作。

#import "AppDelegate.h"
#import "ViewController.h"
@interface AppDelegate ()
@property (nonatomic,strong) ViewController *viewc;
@property (nonatomic,strong) UINavigationController *nav;
@property (nonatomic,strong) UIAlertView *alert;
@end

@implementation AppDelegate
@synthesize viewc = _viewc;
@synthesize nav = _nav;
@synthesize alert = _alert;

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

self.window = [[UIWindow alloc] initWithFrame:[[UIScreen mainScreen] bounds]];
self.window.backgroundColor =[UIColor whiteColor];

_viewc = [[ViewController alloc] initWithNibName:@"ViewController" bundle:nil];
_nav =[[UINavigationController alloc] initWithRootViewController:_viewc];
[_nav setNavigationBarHidden:YES];
self.window.rootViewController = _nav;
[self.window makeKeyAndVisible];
