xmppstream Delegate Methoden werden nicht auf meine benutzerdefinierte Klasse

Question

aufgerufen Ich begann mit Xmppframework vor kurzem, aber ich bin mit einem Problem stecken.Ich kann eine Verbindung zu meinem Server in meinem lokalen Netzwerk, aber die Xmppstreamdelegate Methoden werden nicht auf meine benutzerdefinierte aufgerufen Klasse, aber funktioniert absolut gut auf appdelegate Klasse .Kann jemand pls mir dabei helfen.Ist der Delegierte nur auf der AppDelegate-Klasse unterstützt?

Rubrik:

@interface XmppClass : NSObject<XMPPStreamDelegate>{ 
    XMPPStream *xmppStream; 
    Login * loginDetail; 
    BOOL allowSelfSignedCertificates; 
    BOOL allowSSLHostNameMismatch; 
} 
@property (nonatomic, strong, readonly) XMPPStream *xmppStream; 

@property (nonatomic, strong) Login *loginDetail; 
- (id)initWithLogin:(Login *) loginrefernce; 
- (BOOL)connect; 
- (void)disconnect; 
- (void)setupStream; 
@end 

Umsetzung:

@implementation XmppClass 

@synthesize xmppStream; 
@synthesize loginDetail; 
- (id)initWithLogin:(Login *) loginrefernce 
{ 
    self = [super init]; 
    if (self) { 
     self.loginDetail=loginrefernce; 
     [DDLog addLogger:[DDTTYLogger sharedInstance]]; 
     [self setupStream]; 
     [self connect]; 
    } 
    return self; 
} 
- (void)setupStream 
{ 
NSAssert(xmppStream == nil, @"Method setupStream invoked multiple times"); 
// Setup xmpp stream 
// 
// The XMPPStream is the base class for all activity. 
// Everything else plugs into the xmppStream, such as modules/extensions and delegates. 

xmppStream = [[XMPPStream alloc] init]; 
#if !TARGET_IPHONE_SIMULATOR 
{ 
// Want xmpp to run in the background? 
// 
// P.S. - The simulator doesn't support backgrounding yet. 
//  When you try to set the associated property on the simulator, it simply fails. 
//  And when you background an app on the simulator, 
//  it just queues network traffic til the app is foregrounded again. 
//  We are patiently waiting for a fix from Apple. 
//  If you do enableBackgroundingOnSocket on the simulator, 
//  you will simply see an error message from the xmpp stack when it fails to set the property. 
xmppStream.enableBackgroundingOnSocket = YES; 
} 
#endif 

NSLog(@"setup stream"); 
[xmppStream addDelegate:self delegateQueue:dispatch_get_main_queue()]; 

[xmppStream setHostName:@"10.68.202.123"];

Answer 1

Wahrscheinlich ist das Problem, dass Ihre Klasseninstanz, das ist ein Delegat für Ihren XMPPStream freigegeben wird, bevor Die Delegate-Methode wird aufgerufen. Machen Sie es nachhaltiger, indem Sie diese Klasse zu einer Eigenschaft oder Instanzvariable einer anderen Klasse machen oder indem Sie dispatch_once verwenden. Zum Beispiel

ändern

YourClass *instance = [[YourClass alloc] init]; 
instance.xmppStream = .... 

von

@property(nonatomic, strong) YourClass *instance; 
self.instance = [[YourClass alloc] init]; 
self.instance.xmppStream = .... 

Hier enthält Yourclass XMPPStream und ist für sie delegieren.

Ich habe einen großen Blogbeitrag zu diesem Problem geschrieben. Dies ist eine ziemlich häufige Situation. http://blog.alwawee.com/2013/07/31/on-xmppframework-delegate-method-not-being-called/

Answer 2

können Sie die Multicast verwenden, etw wie diese

[[self appDelegate].xmppStream addDelegate:self delegateQueue:dispatch_get_main_queue()]; 

Answer 3

ich gleiche Problem ... das hat mir geholfen hatte. Hoffe, es funktioniert für Sie, machen Sie einfach folgende Änderungen in Ihrem Code.

Static XmppClass *selfRef = nil; 
@implementation XmppClass 
@synthesize xmppStream; 
- (void)setupStream 
{ 
// Setup xmpp stream 
selfRef = [[XmppClass alloc] init]; 
xmppStream = [[XMPPStream alloc] init]; 
[xmppStream addDelegate:selfRef delegateQueue:dispatch_get_main_queue()];
