我正在试图弄清楚如何为html文件做一个扩展。我刚接触编码和Xcode,并试图创建一个应用程序,但我在编码方面有足够的经验,可以理解什么去哪里,为什么去哪里。
我面临的问题是我需要向html文件添加一个扩展名;例如
(index.html?lc=uk)而不是(index.html)。
我已经创建了一个接口和所有其他所需的信息,但我似乎无法让这部分工作。我在ViewController.m上使用的代码是;
[super viewDidLoad];
NSString *path = [[NSBundle mainBundle] pathForResource:@"index" ofType:@"html" inDirectory:@"354"];
NSURL *url = [NSURL fileURLWithPath:path];
NSURLRequest *request = [NSURLRequest requestWithURL:url];
[webview loadRequest:request];我尝试添加到(pathForResource) @"index.html?lc=uk“,但当我测试应用程序时,它不工作,并给我一个错误。
有人能告诉我我需要做什么吗?
致以亲切的问候,
Seb

如果我没弄错,您需要像这样更改NSString*路径:
path = [NSString stringWithFormat:@"%@?lc=uk", path];但是如果你从来没有尝试过本地路径([NSURL fileURLWithPath:path];),也许你应该使用[NSURL URLWithString:path];?您是否已将HTML-File作为资源,或者您是否正在尝试访问远程源?
对于本地源,GET-Parameter最终甚至没有考虑在内,因为没有PHP或任何安装作为HTML文件处理器的东西。
编辑:
你的来源:
[super viewDidLoad];
NSString *path = [[NSBundle mainBundle] pathForResource:@"index" ofType:@"html" inDirectory:@"354"];
NSURL *url = [NSURL fileURLWithPath:path];
NSURLRequest *request = [NSURLRequest requestWithURL:url];
[webview loadRequest:request];新源:
[super viewDidLoad];
NSString *path = [[NSBundle mainBundle] pathForResource:@"index" ofType:@"html" inDirectory:@"354"];
path = [NSString stringWithFormat:@"%@?lc=uk", path]; // add the '?lc=uk'
NSURL *url = [NSURL URLWithString:path]; // build URL with string
NSURLRequest *request = [NSURLRequest requestWithURL:url];
[webview loadRequest:request];我希望这能对你有所帮助。
