Question

我试图在我的IOS应用程序中下载HTML，一旦我将html加入我的应用程序，我想搜索下载的数据并在两个值之间打印文本。示例：如果我从我的html数据中获取此数据：内容 - 开始狗狗想要做的东西停止

我想在UITextView中在START和STOP之间打印文本，以便人们可以干净地查看文本。有没有办法做到这一点？我到目前为止的代码：

@implementation FirstViewController


//http://www.streakadvice.com/path-to-the-stash-luke.html
- (void)viewDidLoad{

    [super viewDidLoad];
    if (myConnection == nil) {
        myData = [NSMutableData new];
        NSString *urlString = [NSString stringWithFormat:@"http://www.streakadvice.com/path-to-the-stash-luke.html"];
        myConnection = [NSURLConnection connectionWithRequest:
                       [NSURLRequest requestWithURL:
                        [NSURL URLWithString:urlString]]
                                                    delegate:self];

    }

[self.view setBackgroundColor:[UIColor colorWithPatternImage:[UIImage imageNamed:@"SFTCBR3.png"]]];


    NSString *fullURL = @"http://www.streakadvice.com/path-to-the-stash-luke.html";
    NSURL *url = [NSURL URLWithString:fullURL];
    NSURLRequest *requestObj = [NSURLRequest requestWithURL:url];
    [webView loadRequest:requestObj];



}
- (void)connection:(NSURLConnection *)connection didReceiveData:(NSData *)data {
    [myData appendData:data];
}




-(void)initializeVariablesAgain {
    myData = nil;
    myConnection = nil;
    myTextView = nil;
}




- (void)connectionDidFinishLoading:(NSURLConnection *)connection {

    NSString *stringToLookup = [[NSString alloc]initWithData:myData encoding:NSASCIIStringEncoding];

    if ([stringToLookup rangeOfString:@"Start"].location != NSNotFound) {
        myLabel.text = @" ";
    } else {
        myLabel.text = @" ";
    }

    myTextView.text = [[NSString alloc] initWithData:myData encoding:NSASCIIStringEncoding];

    [self initializeVariablesAgain];
}
- (void)didReceiveMemoryWarning
{
    [super didReceiveMemoryWarning];
    // Dispose of any resources that can be recreated.
}

@end

JSON可能不是您正在寻找的格式 - 特别是因为它听起来只是想要一个基本的字符串替换。我可以推荐Get String Between Two Other Strings in ObjC吗？

将HTML下载到JSON
