所以我設法從Twitter獲取飼料,並試圖解析它... 我只需要飼料中的以下領域: 名稱,描述,time_zone和created_at 我成功拔出名稱和說明..但是time_zone和created_at總是零...以下是代碼...TouchXML閱讀Twitter的飼料iphone應用程序
任何人都可以看到爲什麼這可能不起作用?
-(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];
}
在此先感謝您的幫助!

太感謝了..我一直在盯着那個好久,現在我感覺真的很愚蠢......但再次感謝! – Fiona 2010-05-18 11:04:00
Np,我通常是這樣做的,並在if語句中分配一些內容,並想知道爲什麼它總是如此。快樂的編碼 – Rudiger 2010-05-18 11:07:09
