NSString *dcoumentpath = ([paths count] > 0) ? [paths objectAtIndex:0] : nil;  
  
  
NSString* l_zipfile = [dcoumentpath stringByAppendingString:@"/test.zip"] ;  
  
  
 
  
  
NSString* image1 = [dcoumentpath stringByAppendingString:@"/2.png"] ;  
  
  
NSString* image2 = [dcoumentpath stringByAppendingString:@"/3.png"] ;  
  
  
 
  
  
BOOL ret = [zip CreateZipFile2:l_zipfile];  
  
  
ret = [zip addFileToZip:image1 newname:@"2.png"];  
  
  
ret = [zip addFileToZip:image2 newname:@"3.png"];  
  
  
if( ![zip CloseZipFile2] )  
  
  
{  
  
  
    l_zipfile = @"";  
  
  
}  
  
  
[zip release];
