在 XCode 中检测 UIWebView 表单提交
我已经阅读了这里的帖子，但无法完全适应我的需要。我有：
-(IBAction) abouthtml
{
NSString *urlAddress = [[NSBundle mainBundle] pathForResource:@"about" ofType:@"html"];
NSURL *url = [NSURL fileURLWithPath:urlAddress];
NSURLRequest *requestObj = [NSURLRequest requestWithURL:url];
CGRect webViewRect = frameWebSpace;
UIWebView *myWebPage=[[UIWebView alloc] initWithFrame:webViewRect];
[myWebPage loadRequest:requestObj];
[self.view addSubview:myWebPage];
}
这显示正常，但 about.html 中的“返回程序”提交按钮不起作用。
我已经尝试过，正如此处帖子中所建议的那样：
- (BOOL)webView:(UIWebView*)webView shouldStartLoadWithRequest:(NSURLRequest*)request
navigationType:(UIWebViewNavigationType)navigationType
{
if (navigationType == UIWebViewNavigationTypeFormSubmitted)
{
....
但显然，没有任何内容将 myWebPage 链接到 webView。有人可以建议我缺少什么吗？ 我需要让 webView 成为 myWebPage 的委托吗？迷茫，但又充满希望……
I've read the posts here, but cannot quite adapt them to my needs. I have:
-(IBAction) abouthtml
{
NSString *urlAddress = [[NSBundle mainBundle] pathForResource:@"about" ofType:@"html"];
NSURL *url = [NSURL fileURLWithPath:urlAddress];
NSURLRequest *requestObj = [NSURLRequest requestWithURL:url];
CGRect webViewRect = frameWebSpace;
UIWebView *myWebPage=[[UIWebView alloc] initWithFrame:webViewRect];
[myWebPage loadRequest:requestObj];
[self.view addSubview:myWebPage];
}
This displays fine, but my "Return to Program" submit button in about.html is not working.
I've tried, as suggested in posts here:
- (BOOL)webView:(UIWebView*)webView shouldStartLoadWithRequest:(NSURLRequest*)request
navigationType:(UIWebViewNavigationType)navigationType
{
if (navigationType == UIWebViewNavigationTypeFormSubmitted)
{
....
But obviously, nothing links myWebPage to webView. Can someone suggest what I'm missing?
Do I need to make webView a delegate of myWebPage? Confused, but hopeful...

您必须将
UIWebView的委托设置为实现shouldStartLoadWithRequest、[myWebPage setDelegate:self]的对象，假设该类添加了子视图是您想要接收shouldStartLoadWithRequest消息的视图you have to set the delegate of
UIWebViewto be the object that implementsshouldStartLoadWithRequest,[myWebPage setDelegate:self], assuming that class that adds the subview is the one you want to receive theshouldStartLoadWithRequestmessage将
myWebPage的委托设置为实现的对象（在您的情况下可能是 self）Set
myWebPage's delegate to the object that implements (in your case probably self)
