UITextView 中 HTML 页面的一部分
我试图在 ASIHttpRequest 和 NSRange 的帮助下打开 html 页面的一部分，但它不起作用。 我的代码：
- (void)requestFinished:(ASIHTTPRequest *)request
{
// Use when fetching text data
NSLog(@"Loaded");
NSString *htmlString = [request responseString];
NSString *string = @"<a>";
NSRange range = [htmlString rangeOfString:string];
if (range.location != NSNotFound)
{
range.length += range.location;
range.location = 0;
string = @"</a>";
NSRange rangeOpen = [htmlString rangeOfString:string options:NSBackwardsSearch range:range];
if (rangeOpen.location != NSNotFound)
{
range.length -= rangeOpen.location;
range.location = rangeOpen.location;
htmlString = [htmlString stringByReplacingCharactersInRange:range withString:@""];
NSLog(@"Range %@", NSStringFromRange(range));
NSLog(@"%@", htmlString);
}
}
}
这是用于删除标签的代码，我想对其进行转换。例如：我想在 UILabel 或 UITextView 中的标签之间打开文本
I'm trying to open part of html page with help of ASIHttpRequest and NSRange, but it isn't working.
My code:
- (void)requestFinished:(ASIHTTPRequest *)request
{
// Use when fetching text data
NSLog(@"Loaded");
NSString *htmlString = [request responseString];
NSString *string = @"<a>";
NSRange range = [htmlString rangeOfString:string];
if (range.location != NSNotFound)
{
range.length += range.location;
range.location = 0;
string = @"</a>";
NSRange rangeOpen = [htmlString rangeOfString:string options:NSBackwardsSearch range:range];
if (rangeOpen.location != NSNotFound)
{
range.length -= rangeOpen.location;
range.location = rangeOpen.location;
htmlString = [htmlString stringByReplacingCharactersInRange:range withString:@""];
NSLog(@"Range %@", NSStringFromRange(range));
NSLog(@"%@", htmlString);
}
}
}
It was code for removing tags and I want to transform it. For example: I want to open text between tags in UILabel or UITextView

您是否将该 ASIHTTPRequest 上的委托设置为范围检查代码所在的对象？
您尝试使用的方法是委托方法，我可以看到它在签入的 GitHub 存储库中声明。

Did you set your delegate on that ASIHTTPRequest to the object where your range checking code lives?
The method you're trying to use is a delegate method, and I can see it declared in the checked-in GitHub repository.
