取消当前NSXMLParser解析操作的简便方法？
|
好的。
假设我有一个“ 0”，用户可以在其中输入网址，例如：
http://foo.bar/foo/bar.asmx
NSData
http://apple.com/foo/bar.asmx
-(void)connectionDidFinishLoading:(NSURLConnection *)connection
{
xmlParser = [[NSXMLParser alloc] initWithData:myData];
[xmlParser setDelegate:self];
[xmlParser shouldResolveExternalEntities:YES];
[xmlParser parse];
[self performSelector:@selector(timeOutMyParser:) withObject:nil afterdelay:15];
[xmlParser release];
[connection release];
[myData release];
}
没有找到相关结果

会返回一个布尔值，如果解析成功，该值为YES。否则返回NO。因此，只需接收布尔值即可。解析时，如果您在XML中收到无效数据，或者要根据条件停止解析，则可以通过调用取消解析您可以检查状态并采取适当的措施。BOOL parserSucceeded = [xmlParser parse]; if (parserSucceeded) { // Parser Succeeded } else { // Parser Failed/Aborted }驮帽俺篮号
-(void)connectionDidFinishLoading:(NSURLConnection *)connection { xmlParser = [[NSXMLParser alloc] initWithData:myData]; [xmlParser setDelegate:self]; [xmlParser shouldResolveExternalEntities:YES]; [xmlParser parse]; [self performSelector:@selector(timeOutMyParser:) withObject:nil afterdelay:15]; [xmlParser release]; [connection release]; [myData release]; }-(void)connectionDidFinishLoading:(NSURLConnection *)connection { xmlParser = [[NSXMLParser alloc]init]; [xmlParser setDelegate:self]; [xmlParser shouldResolveExternalEntities:YES]; [self performSelectorInBackground:@selector(someFunction) withObject:xmlParser]; [xmlParser release]; [connection release]; [myData release]; }是这样的。-(void)someFunction:(NSXMLParser *)parser { parser = [[NSXMLParser alloc]initWithData:myData]; [parser setDelegate:self]; [parser parse]; [parser release]; }
