【问题描述】：
所以我已经设法从 twitter 获取提要并尝试解析它...... 我只需要提要中的以下字段： 名称、描述、time_zone 和 created_at 我成功提取了名称和描述.. 但是 time_zone 和 created_at 总是为零...以下是代码...
有人知道为什么这可能不起作用吗？
-(void) friends_timeline_callback:(NSData *)data{
NSString *string = [[NSString alloc] initWithData:data encoding:NSASCIIStringEncoding];
NSLog(@"Data from twitter: %@", string);
NSMutableArray *res = [[NSMutableArray alloc] init];
CXMLDocument *doc = [[[CXMLDocument alloc] initWithData:data options:0 error:nil] autorelease];
NSArray *nodes = nil;
//! searching for item nodes
nodes = [doc nodesForXPath:@"/statuses/status/user" error:nil];
for (CXMLElement *node in nodes)
{
int counter;
Contact *contact = [[Contact alloc] init];
for (counter = 0; counter < [node childCount]; counter++)
{
//pulling out name and description only for the minute!!!
if ([[[node childAtIndex:counter] name] isEqual:@"name"]){
contact.name = [[node childAtIndex:counter] stringValue];
}else if ([[[node childAtIndex:counter] name] isEqual:@"description"]) {
// common procedure: dictionary with keys/values from XML node
if ([[node childAtIndex:counter] stringValue] == NULL){
contact.nextAction = @"No description";
}else{
contact.nextAction = [[node childAtIndex:counter] stringValue];
}
}else if ([[[node childAtIndex:counter] name] isEqual:@"created_at"]){
contact.date == [[node childAtIndex:counter] stringValue];
}else if([[[node childAtIndex:counter] name] isEqual:@"time_zone"]){
contact.status == [[node childAtIndex:counter] stringValue];
[res addObject:contact];
[contact release];
}
}
}
self.contactsArray = res;
[res release];
[self.tableView reloadData];
}
提前感谢您的帮助！！
