试图分析具有XML数据的两个不同的URL。需要使用NSOperationQueue来解析两个不同的NSOperation类
static NSString *string1 = @"http://abc.com/abc1.xml";
NSURLRequest *URL1 =[NSURLRequest requestWithURL:[NSURL URLWithString:string1]];
self.URL1Connection =[[[NSURLConnection alloc] initWithRequest:URL1 delegate:self] autorelease];
static NSString *string2 = @"http://abc.com/abc2.xml";
NSURLRequest *URL2 =[NSURLRequest requestWithURL:[NSURL URLWithString:string2]];
self.URL2Connection =[[[NSURLConnection alloc] initWithRequest:URL2 delegate:self] autorelease];
我有两个不同的NSOperation类都独立工作，因为他们都有自己的工作要完成。 我有一个parseQueue这是NSOperationqueue我已经添加了两个不同的操作。
TestOperation *testOperation = [[TestOperation alloc]
initWithData:self.data1 delegate:self ];
[self.parseQueue addOperation:testOperation];
[testOperation release]; // once added to the NSOperationQueue it's retained, we don't need it anymore
testOperation = nil;
Test1Operation *test1Operation = [[Test1Operation alloc]
initWithData:self.data2];
[self.parseQueue addOperation:test1Operation];
[test1Operation release]; // once added to the NSOperationQueue it's retained, we don't need it anymore
test1Operation = nil;
基本上我试图解析两个xml数据分别并希望有并发操作。但是当第二个操作重新加入队列时，它仍然会查看第一类操作。我迷失在这里，因为我不知道为什么它在发布后仍然在寻找头等舱。任何人都可以提出一些想法并帮助我。
