我正在按照教程： http://mobile.tutsplus.com/tutorials/iphone/building-a-jabber-client-for-ios-server-setup/設置帶有ejabberd服務器的iOS應用程序。到目前爲止，我幾乎將代碼複製到一個新項目中。在模擬器中調用XMPPFramework委託函數，但不在電話上
我的問題是，在手機上運行時，不會調用XMPP委託函數AppDelegate.m。一切工作正常在模擬器和下面的兩個函數被調用。
- (void)xmppStreamDidConnect:(XMPPStream *)sender {
NSLog(@"in WSAppDelegate - xmppStreamDidConnect");
isOpen = YES;
NSError *error = nil;
[[self xmppStream] authenticateWithPassword:password error:&error];
}
- (void)xmppStreamDidAuthenticate:(XMPPStream *)sender {
NSLog(@"in WSAppDelegate - xmppStreamDidAuthenticate");
[self goOnline];
}
我能夠在手機和模擬器上都連接爲這個調用運行沒有錯誤：
[xmppStream connect:&error]
這裏是我的AppDelegate.h代碼：
#import <UIKit/UIKit.h>
#import "XMPPRoster.h"
#import "XMPP.h"
#import "SMChatDelegate.h"
#import "SMMessageDelegate.h"
@class SMBuddyListViewController;
@interface WSAppDelegate : NSObject <UIApplicationDelegate> {
UIWindow *window;
SMBuddyListViewController *viewController;
XMPPStream *xmppStream;
XMPPRoster *xmppRoster;
NSString *password;
BOOL isOpen;
}
@property (nonatomic, retain) IBOutlet UIWindow *window;
@property (nonatomic, retain) IBOutlet SMBuddyListViewController *viewController;
@property (nonatomic, readonly) XMPPStream *xmppStream;
@property (nonatomic, readonly) XMPPRoster *xmppRoster;
@property (nonatomic, assign) id _chatDelegate;
@property (nonatomic, assign) id _messageDelegate;
- (BOOL)connect;
- (void)disconnect;
@end
而且AppDelegate中。 m：
#import "WSBuddyListViewController.h"
@interface WSAppDelegate()
- (void)setupStream;
- (void)goOnline;
- (void)goOffline;
@end

}

非常感謝。我被部分拋出，因爲[xmppStream connect：＆error]被調用時沒有返回錯誤，我認爲初始連接已經完成，但錯誤發生在某處之後。 – Ramsel 2013-03-07 03:49:13
