如何從Javascript調(diào)用Object-C？我有一個(gè)WebView，我想從JavaScript調(diào)用Object-C中的一個(gè)視圖。有人知道我該怎么做嗎？我的ViewController中有以下代碼：- (BOOL)webView:(UIWebView *)webView2
shouldStartLoadWithRequest:(NSURLRequest *)request
navigationType:(UIWebViewNavigationType)navigationType {
NSString *requestString = [[request URL] absoluteString];
NSArray *components = [requestString componentsSeparatedByString:@":"];
if ([components count] > 1 &&
[(NSString *)[components objectAtIndex:0] isEqualToString:@"myapp"]) {
if([(NSString *)[components objectAtIndex:1] isEqualToString:@"myfunction"])
{
NSLog([components objectAtIndex:2]); [[Airship shared] displayStoreFront]; //<- This is the code to open the Store
NSLog([components objectAtIndex:3]); // param2
// Call your method in Objective-C method using the above...
}
return NO;
}
return YES; // Return YES to make sure regular navigation works as expected.}在Javascript中：function store(event){
document.location = "myapp:" + "myfunction:" + param1 + ":" + param2;}但什么都沒發(fā)生。
