常用COCOA函数笔记

1 NSUserDefaults

[[NSUserDefaults standardUserDefaults] boolForKey:kHomeButtonSetting]
[[NSUserDefaults standardUserDefaults] setBool:self.isVoiceMode forKey:kHomeButtonSetting];

2 NSMutableArray

NSArray *array= [[NSUserDefaults standardUserDefaults] arrayForKey:SELES_CITYS]  ;
self.historys = [NSMutableArray arrayWithArray:array] ;
//保证栈的顺序
if ([self.historys containsObject:city]) {
   [self.historys removeObject:city];
}

if (self.historys.count >=5) {
   [self.historys removeLastObject];
}

[self.historys insertObject:city atIndex:0 ];
[[NSUserDefaults standardUserDefaults] setObject:self.historys forKey:SELES_CITYS];

3 NSDictionary

NSString *path=[[NSBundle mainBundle] pathForResource:@"citydict"
                                               ofType:@"plist"];
cities = [[NSDictionary alloc]initWithContentsOfFile:path];
keys = [[cities allKeys] sortedArrayUsingSelector:@selector(compare:)];

4 NSBundle

NSString *path=[[NSBundle mainBundle] pathForResource:@"citydict"
                                               ofType:@"plist"];

let path = NSBundle.mainBundle().pathForResource(name, ofType:ext)

NSString* networkPath = [[NSBundle mainBundle] pathForResource:@"jetpac" ofType:@"ntwk"];
     if (networkPath == NULL) {
         fprintf(stderr, "Couldn't find the neural network parameters file - did you add it as a resource to your application?\n");
         assert(false);
     }
     network = jpcnn_create_network([networkPath UTF8String]);

5 NSNotificationCenter

[[NSNotificationCenter defaultCenter] postNotificationName:@"com.chinaso.showListener" object:nil];
   
   NSNotificationCenter.defaultCenter().addObserverForName("com.chinaso.showListener", object: nil, queue: NSOperationQueue.mainQueue()) { (notification:NSNotification!) -> Void in    
            self.voice()
        }
        NSNotificationCenter.defaultCenter().addObserverForName("com.chinaso.showScaner", object: nil, queue: NSOperationQueue.mainQueue()) { (notification:NSNotification!) -> Void in
            
            self.barcode()

6 Local NSNotification

- (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions {
    // Override point for customization after application launch.
    
    //注册申请 local notification
    if ([UIApplication instancesRespondToSelector:@selector(registerUserNotificationSettings:)]) {
        [application registerUserNotificationSettings:[UIUserNotificationSettings settingsForTypes:UIUserNotificationTypeAlert |UIUserNotificationTypeBadge|UIUserNotificationTypeSound categories:nil]];
    }
    
    [UIApplication sharedApplication].applicationIconBadgeNumber=0 ;
    return YES;
}

// 在后端，当用户点击通知时候，收到
-(void) application:(UIApplication *)application didReceiveLocalNotification:(UILocalNotification *)notification {
    
    NSLog(@"%@" ,notification) ;
    
    [UIApplication sharedApplication].applicationIconBadgeNumber=8;
}
    
    
 -(void) doSendNotifaction {
   UILocalNotification *notifcation = [[UILocalNotification alloc] init];
   notifcation.fireDate = [NSDate dateWithTimeIntervalSinceNow:10] ;
   notifcation.alertBody = @"测试 local notification" ;

   
//    [[UIApplication sharedApplication] scheduledLocalNotifications:notifcation];
   [[UIApplication sharedApplication] scheduleLocalNotification:notifcation];
}
