我有以下代码,想使用NSMutable数组代替NSArray,请问如何加载NSMutable数组,因为当前的方法不起作用。
-(void) whatever{
NSData *htmlData = [[NSString stringWithContentsOfURL:[NSURL URLWithString: @"http://www.objectgraph.com/contact.html"]] dataUsingEncoding:NSUTF8StringEncoding];
TFHpple *xpathParser = [[TFHpple alloc] initWithHTMLData:htmlData];
NSArray *titles = [xpathParser search:@"//h3"]; // get the page title - this is xpath notation
TFHppleElement *title = [titles objectAtIndex:0];
NSString *myTitles = [title content];
NSArray *articles = [xpathParser search:@"//h4"]; // get the page article - this is xpath notation
TFHppleElement *article = [articles objectAtIndex:0];
NSString *myArtical = [article content];
我已经尝试过:
NSMutableArray *titles = [xpathParser search:@"//h3"];
但它确实加载了值吗?
