StringWithContentsOfURL assumes the web page is formatted as
NSMacOSRomanEncoding, which is not always the case. Most often, it is
encoded as NSISOLatin1StringEncoding.
Use this method instead:
- (NSString*) downloadWebPage:(NSString*)url
{
NSData* data;
NSString* encodedString;
data = [[NSData alloc] initWithContentsOfURL:[NSURL URLWithString:url]];
if(data == nil)
return nil;
encodedString = [[[NSString alloc] initWith
Data:data
encoding:NSISOLatin1StringEncoding] autorelease];
[data release];
return encodedString;
}
If you need to explicitely converts the string to NSMacOSRomanEncoding, use:
data = [encodedString dataUsingEncoding:NSMacOSRomanStringEncoding
allowLossyConversion:YES];
[encodedString release];
encodedString = [[NSString alloc] initWith
Data:data encoding:
NSMacOSRomanStringEncoding];
