NSURLConnection problem?

Question

HI, i am using sample code from to handle Multiple NSUrlCOnnection from the link multiple url connection

when i use CustomURLConnection as NSObject inwhich i specified one Method as to enable

CustomURLConnection *connection = [[CustomURLConnection alloc] initWithRequest:request delegate:self startImmediately:YES tag:tag]; 

through the following

 - (id)initWithRequest:(NSURLRequest *)request delegate:(id)delegate   startImmediately:(BOOL)startImmediately tag:(NSString *)_tag

 {
connection = [[NSURLConnection alloc] initWithRequest:request delegate:delegate startImmediately:startImmediately];
self.tag = _tag;
return self;
  }

it gives error?

Answer 1

I think you should try:

- (id)initWithRequest:(NSURLRequest *)request delegate:(id)delegate   startImmediately:(BOOL)startImmediately tag:(NSString *)_tag
 {
    if(self = [super initWithRequest:request delegate:delegate])
    {   
       self.tag = _tag;
    }
    return self;
  }

(If I got you right and CustomURLConnection extends NSURLConnection and the code you pasted is CustomURLConnection's init code.)

Answer 2

The problem is that there is no self. If CustomURLConnection inherits from NSObjectthe method should look like this:

- (id)initWithRequest:(NSURLRequest *)request delegate:(id)delegate   startImmediately:(BOOL)startImmediately tag:(NSString *)_tag {
      if(self = [super init]) {
         self.connection = [[[NSURLConnection alloc] initWithRequest:request delegate:delegate startImmediately:startImmediately] autorelease];
         self.tag = _tag;
      }
      return self;
 }

You should also make sure that connection is an iVar of that Class and gets properly released in dealloc. Same for tagmake sure to add

 @synthesize tag,connection;

after @implementation and to declare a tag iVar and property.
