搜索XML提要usind iPhone
答
您需要使用XML解析来实现this.I建议使用touchXML
- (无效){callwebservice
NSString *path = @"YOUR URL";
[self grabRSSFeed:path];
}

- (空)grabRSSFeed:(的NSString *)blogAddress {
// Initialize the blogEntries MutableArray that we declared in the header
blogEntries = [[NSMutableArray alloc] init];
// Convert the supplied URL string into a usable URL object
NSURL *url = [NSURL URLWithString: blogAddress];
// Create a new rssParser object based on the TouchXML "CXMLDocument" class, this is the
// object that actually grabs and processes the RSS data
CXMLDocument *rssParser = [[[CXMLDocument alloc] initWithContentsOfURL:url options:0 error:nil] autorelease];
// Create a new Array object to be used with the looping of the results from the rssParser
NSArray *resultNodes = NULL;
// Set the resultNodes Array to contain an object for every instance of an node in our RSS feed
resultNodes = [rssParser nodesForXPath:@"//Node you want to parse" error:nil];
// Loop through the resultNodes to access each items actual data
for (CXMLElement *resultElement in resultNodes) {
// Create a temporary MutableDictionary to store the items fields in, which will eventually end up in blogEntries
NSMutableDictionary *blogItem = [[NSMutableDictionary alloc] init];
// Create a counter variable as type "int"
int counter;
// Loop through the children of the current node
for(counter = 0; counter < [resultElement childCount]; counter++) {
// Add each field to the blogItem Dictionary with the node name as key and node value as the value
[blogItem setObject:[[resultElement childAtIndex:counter] stringValue] forKey:[[resultElement childAtIndex:counter] name]];
NSLog(@"Data = %@",[[resultElement childAtIndex:counter] stringValue]);
}
// Add the blogItem to the global blogEntries Array so that the view can access it.
[blogEntries addObject:[blogItem copy]];
}
[YourTable reloadData];
}
进口touchXML库在你的头文件。

答复您好感谢,将为用户提供搜索字符串像CNN或BBC和应用程序需要搜索互联网来获取RSS XML的URL。你的代码是要求URL?如何用CNN或BBC这样的字符串来做到这一点。? – likki 2010-12-02 04:17:11
