ASIHTTPRequest 在同步模式下吞噬了我的 NSOperation 变量

嘿，我已经和这个问题作斗争有一段时间了。也许我在有关多线程的知识中缺少一些东西，但这就是发生的事情。当我创建 nsoperation 队列时，分配的任何变量都会在“[request startSynchronous];”之后被清除。行代码。这就是我要说的：

@implementation imageLoadOperation
@synthesize object;

-(id)initWithObject:(NSMutableArray *)receivedObject
{
 ...
 object = receivedObject;
 ...
}
- (void)main {
 ...
//send request
 printf("retreiving photo info from server\n");

 NSURL *url = [NSURL URLWithString:[siteUrl stringByAppendingString:@"/connect.php"]];
 ASIFormDataRequest *request = [ASIFormDataRequest requestWithURL:url];
 [request setPostValue:@"lookAtPhoto" forKey:@"purpose"];
 [request setRequestCookies: [ASIHTTPRequest sessionCookies]];

该对象仍然存在于此处

[请求开始同步];

然后物体就消失在这里了！

我确信这与原则理解上的差距有关，但我已经重新安排代码好几天了，但没有成功。

Hey I have been battling with this problem for a while now. Perhaps there is something I am missing in knowledge about multi threading but here is what happens. When I create an nsoperation queue any variables that are allocated become cleared after the "[request startSynchronous];" line of code. Here is what I'm talking about:

@implementation imageLoadOperation
@synthesize object;

-(id)initWithObject:(NSMutableArray *)receivedObject
{
 ...
 object = receivedObject;
 ...
}
- (void)main {
 ...
//send request
 printf("retreiving photo info from server\n");

 NSURL *url = [NSURL URLWithString:[siteUrl stringByAppendingString:@"/connect.php"]];
 ASIFormDataRequest *request = [ASIFormDataRequest requestWithURL:url];
 [request setPostValue:@"lookAtPhoto" forKey:@"purpose"];
 [request setRequestCookies: [ASIHTTPRequest sessionCookies]];

The object still exists here
