ASIHTTPRequest and userInfo

Question

According to the website for ASIHTTPRequest:

If your requests are all of the same broad type, but you want to distinguish between them, you can set the userInfo NSDictionary property of each request with your own custom data that you can read in your finished / failed delegate methods.

How do I set userInfo?

NSURL *url = [NSURL URLWithString:@"http://www.google.com"];
ASIFormDataRequest *request = [[ASIFormDataRequest alloc] initWithURL:url];
[request setDelegate:self];
[request startAsynchronous];

Answer 1

request.userInfo = [NSDictionary dictionaryWithObjectsAndKeys: dataObject, key, nil];

Answer 2

request.userInfo = [[NSMutableDictionary alloc] initWithObjectsAndKeys:@"init", @"operation", nil];

否则你会得到一个错误：mutating方法发送到immutable objectt

Answer 3

如果您更喜欢使用括号来表示点符号：

[request setUserInfo:[[NSMutableDictionary alloc] initWithObjectsAndKeys:@"init", @"operation", nil]];
