私のカスタムクラスでxmppstreamデリゲートメソッドが呼び出されない

Question

最近xmppframeworkを使い始めましたが、問題が残っています。私のローカルネットワーク上のサーバーに接続できますが、xmppstreamdelegateメソッドがカスタムクラスは、appdelegateクラスで絶対に正常に動作します。誰でもこの上で私を助けてもらえますか？デリゲートはappdelegateクラスでのみサポートされていますか？

ヘッダー：

@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 

実装：

@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"]; 
//[xmppStream setHostPort:8070]; 

allowSelfSignedCertificates = NO; 
allowSSLHostNameMismatch = NO; 

// You may need to alter these settings depending on the server you're connecting to 

}

// uncomment the section below to hard code a JID and password. 
// 
// myJID = @"user@gmail.com/xmppframework"; 
// myPassword = @""; 
if (self.loginDetail.emailId == nil || self.loginDetail.password == nil) { 
    return NO; 
} 

[xmppStream setMyJID:[XMPPJID jidWithString:[self.loginDetail.emailId  stringByAppendingString:@"/pc"]]];

Answer 1

おそらく問題は、あなたのクラスのインスタンスは、それがあなたのXMPPStreamためのデリゲートが前にリリースされたということですデリゲートメソッドが呼び出されます。このクラスを他のクラスのプロパティまたはインスタンス変数にするか、またはdispatch_onceを使用して、より永続的にします。例えば、

変更

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

によって

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

ここYOURCLASSはXMPPStreamが含まれており、それのために委任されています。

私はこの問題に関する大きなブログ記事を書いています。これはかなり一般的な状況です。 http://blog.alwawee.com/2013/07/31/on-xmppframework-delegate-method-not-being-called/

Answer 2

あなたは、これは私を助けて...私は同じ問題を抱えていたこの

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

Answer 3

のように、マルチキャスト、STHを使用することができます。あなたのコードに以下の変更を加えてください。

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()];
