我在下面的代码中调用 javascript，它运行良好，然后我在该 javascript 中附加 HTML 内容，当我在 IF 条件下检查 URL 方案时，它失败了。
- (void)connectionDidFinishLoading:(NSURLConnection *)connection
{
if(_data)
{
NSString* content = [[NSString alloc] initWithData:_data
encoding:NSUTF8StringEncoding];
[_data release];
_data = nil;
NSString *jsString = @"<script type='text/javascript'>\
window.external =\
{\
'Notify': function(s) { document.location = 'acs://settoken?token=' + s; },\
'notify': function(s) { document.location = 'acs://settoken?token=' + s; }\
}\
</script>";
content = [jsString stringByAppendingString:content];
[webView loadHTMLString:content baseURL:_url];
}
}
- (BOOL)webView:(UIWebView *)webView
shouldStartLoadWithRequest:(NSURLRequest *)request
navigationType:(UIWebViewNavigationType)navigationType
{
if(_url)
{
if([_url isEqual:[request URL]])
{
return YES;
}
[_url release];
}
_url = [[request URL] retain];
NSString* scheme = [_url scheme];
//Here I'm checking the condition
if([scheme isEqualToString:@"acs"])
{
// parse the JSON URL parameter into a dictionary
NSDictionary* pairs = [self parsePairs:[_url absoluteString]];
if(pairs)
{
WACloudAccessToken* accessToken;
accessToken = [[WACloudAccessToken alloc] initWithDictionary:pairs];
[WACloudAccessControlClient setToken:accessToken];
[self dismissModalViewControllerAnimated:YES];
}
return NO;
}
[NSURLConnection connectionWithRequest:request delegate:self];
return NO;
}
有任何想法吗？提前致谢。
