xmppframework for iOS client(五) 添加AutoPing
为了监听服务器是否有效,增加心跳监听。用XEP-0199协议,在XMPPFrameWork框架下,封装了 XMPPAutoPing 和 XMPPPing两个类都可以使用,因为XMPPAutoPing已经组合进了XMPPPing类,所以XMPPAutoPing使用起来更方便。
首先,导入头文件
#import "XMPPAutoPing.h"
声明成员变量和属性
@interface XMPPConnectManeger : NSObject<XMPPAutoPingDelegate>
{
XMPPAutoPing *_xmppAutoPing;
}
@property (nonatomic, retain) XMPPAutoPing *xmppAutoPing;
在实现文件中
@synthesize xmppStream = _xmppStream;
@synthesize xmppAutoPing = _xmppAutoPing;
//初始化并启动ping
-(void)autoPingProxyServer:(NSString*)strProxyServer
{
_xmppAutoPing = [[XMPPAutoPingalloc] init];
[_xmppAutoPingactivate:_xmppStream];
[_xmppAutoPingaddDelegate:selfdelegateQueue: dispatch_get_main_queue()];
_xmppAutoPing.respondsToQueries = YES;
_xmppAutoPing.pingInterval=2;//ping 间隔时间
if (nil != strProxyServer)
{
_xmppAutoPing.targetJID = [XMPPJID jidWithString: strProxyServer ];//设置ping目标服务器,如果为nil,则监听socketstream当前连接上的那个服务器
}
}
//卸载监听
[_xmppAutoPing deactivate];
[_xmppAutoPing removeDelegate:self];
_xmppAutoPing = nil;
//ping XMPPAutoPingDelegate的委托方法:
- (void)xmppAutoPingDidSendPing:(XMPPAutoPing *)sender
{
NSLog(@"- (void)xmppAutoPingDidSendPing:(XMPPAutoPing *)sender");
}
- (void)xmppAutoPingDidReceivePong:(XMPPAutoPing *)sender
{
NSLog(@"- (void)xmppAutoPingDidReceivePong:(XMPPAutoPing *)sender");
}
- (void)xmppAutoPingDidTimeout:(XMPPAutoPing *)sender
{
NSLog(@"- (void)xmppAutoPingDidTimeout:(XMPPAutoPing *)sender");
}
