네트워크 오류 경고 코드를 표시하도록 앱을 설치하려고합니까?

Question

그래,이 응용 프로그램에 네트워크 오류 경고 코드를 표시하려고합니다. SystemConfiguration.framework 프레임 워크와 Apple의 "Reachability"샘플 코드를 추가했습니다. 여기

는 viewcontroller.h 파일입니다

#import <UIKit/UIKit.h> 

@class Reachability; 

@interface Test_Internet_ConnectionViewController : UIViewController { 

    Reachability* internetReachable; 
    Reachability* hostReachable; 
} 

- (void) checkNetworkStatus:(NSNotification *)notice; 

@end 

그리고 여기 viewcontroller.m 파일입니다

#import "Test_Internet_ConnectionViewController.h" 
#import "Reachability.h"; 

@implementation Test_Internet_ConnectionViewController 



/* 
// The designated initializer. Override to perform setup that is required before the view is loaded. 
- (id)initWithNibName:(NSString *)nibNameOrNil bundle:(NSBundle *)nibBundleOrNil { 
    self = [super initWithNibName:nibNameOrNil bundle:nibBundleOrNil]; 
    if (self) { 
     // Custom initialization 
} 
    return self; 
    } 
*/ 

/* 
// Implement loadView to create a view hierarchy programmatically, without using a nib. 
- (void)loadView { 
} 
*/ 


// Implement viewDidLoad to do additional setup after loading the view, typically from a nib. 
- (void)viewDidLoad { 
    [super viewDidLoad]; 

     // check for internet connection 
     [[NSNotificationCenter defaultCenter] addObserver:self selector:@selector(checkNetworkStatus:) name:kReachabilityChangedNotification object:nil]; 

     internetReachable = [[Reachability reachabilityForInternetConnection] retain]; 
     [internetReachable startNotifier]; 

     // check if a pathway to a random host exists 
     hostReachable = [[Reachability reachabilityWithHostName: @"www.apple.com"] retain]; 
     [hostReachable startNotifier]; 

     // now patiently wait for the notification 
    } 

/* 
// Override to allow orientations other than the default portrait orientation. 
- (BOOL)shouldAutorotateToInterfaceOrientation:(UIInterfaceOrientation)interfaceOrientation { 
    // Return YES for supported orientations 
    return (interfaceOrientation == UIInterfaceOrientationPortrait); 
} 
*/ 

- (void)didReceiveMemoryWarning { 
    // Releases the view if it doesn't have a superview. 
    [super didReceiveMemoryWarning]; 

    // Release any cached data, images, etc that aren't in use. 
} 

- (void)viewDidUnload { 
    // Release any retained subviews of the main view. 
    // e.g. self.myOutlet = nil; 
} 

- (void) checkNetworkStatus:(NSNotification *)notice 
{ 
    // called after network status changes 

    NetworkStatus internetStatus = [internetReachable currentReachabilityStatus]; 
    switch (internetStatus) 

    { 
     case NotReachable: 
     { 
      NSLog(@"The internet is down."); 
      self.internetActive = NO; 

      break; 

     } 
     case ReachableViaWiFi: 
     { 
      NSLog(@"The internet is working via WIFI."); 
      self.internetActive = YES; 

      break; 

     } 
     case ReachableViaWWAN: 
     { 
      NSLog(@"The internet is working via WWAN."); 
      self.internetActive = YES; 

      break; 

     } 
    } 

    NetworkStatus hostStatus = [hostReachable currentReachabilityStatus]; 
    switch (hostStatus) 

    { 
     case NotReachable: 
     { 
      NSLog(@"A gateway to the host server is down."); 
      self.hostActive = NO; 

      break; 

     } 
     case ReachableViaWiFi: 
     { 
      NSLog(@"A gateway to the host server is working via WIFI."); 
      self.hostActive = YES; 

      break; 

     } 
     case ReachableViaWWAN: 
     { 
      NSLog(@"A gateway to the host server is working via WWAN."); 
      self.hostActive = YES; 

      break; 

     } 
    } 
} 

- (void)dealloc { 
    [super dealloc]; 




     [[NSNotificationCenter defaultCenter] removeObserver:self]; 

    } 

@end 

내가 6 오류를 얻을 : 멤버

요청 'internetActive' (3 번) 구조체 또는 공용체가 아닌 무언가에 'hostActive'멤버에 대한 요청 (3 번)

Answer 1

클래스 변수 또는 속성으로 'internetActive'및 'hostActive'를 만들고 있습니까? 나는 당신이 제공 한 코드에서 이것을 어디에도 보지 못했다.
