我正在尝试从UIWebView打开链接并将其打开到另一个应用程序。 我首先在社交媒体上测试它,Facebook和Twitter运行良好,但Instagram和Youtube不是。请参阅下面的代码。
- (BOOL)webView:(UIWebView *)webView shouldStartLoadWithRequest:(NSURLRequest *)request navigationType:(UIWebViewNavigationType)navigationType
{
if (navigationType == UIWebViewNavigationTypeLinkClicked ) {
if ([request.URL.scheme isEqualToString:@"https"]) {
if ([request.URL.host isEqualToString:@"www.facebook.com"]) {
NSLog(@"FB FROM WEBVIEW BUTTON");
if ([[UIApplication sharedApplication] canOpenURL:[NSURL URLWithString:@"fb://"]]) {
[[UIApplication sharedApplication] openURL:[NSURL URLWithString:@"fb://profile/FlawlessFaceandBody"]];
}
else {
[[UIApplication sharedApplication] openURL:[NSURL URLWithString:@"https://www.facebook.com/FlawlessFaceandBody/"]];
NSLog(@"No FB APP");
}
[self homepage];
}
return YES;
}
else if ([request.URL.scheme isEqualToString:@"https"]) {
if ([request.URL.host isEqualToString:@"twitter.com/myflawless"]) {
NSLog(@"TW FROM WEBVIEW BUTTON");
if ([[UIApplication sharedApplication] canOpenURL:[NSURL URLWithString:@"twitter://"]]) {
[[UIApplication sharedApplication] openURL:[NSURL URLWithString:@"twitter://profile/myflawless"]];
}
else {
[[UIApplication sharedApplication] openURL:[NSURL URLWithString:@"https://twitter.com/myflawless?ref_src=twsrc%5Egoogle%7Ctwcamp%5Eserp%7Ctwgr%5Eauthor"]];
NSLog(@"No TW APP");
}
[self homepage];
}
return YES;
}
else if ([request.URL.scheme isEqualToString:@"https"]) {
if ([request.URL.host isEqualToString:@"instagram.com/myflawless"]) {
NSLog(@"IG FROM WEBVIEW BUTTON");
if ([[UIApplication sharedApplication] canOpenURL:[NSURL URLWithString:@"instagram:/user/"]]) {
[[UIApplication sharedApplication] openURL:[NSURL URLWithString:@"instagram://profile/myflawless"]];
}
else {
[[UIApplication sharedApplication] openURL:[NSURL URLWithString:@"https://www.instagram.com/myflawless/"]];
NSLog(@"No IG APP");
}
[self homepage];
}
return YES;
}
}
else if ([request.URL.scheme isEqualToString:@"https"]) {
if ([request.URL.host isEqualToString:@"youtube.com/FlawlessFaceandBody"]) {
NSLog(@"YT FROM WEBVIEW BUTTON");
if ([[UIApplication sharedApplication] canOpenURL:[NSURL URLWithString:@"youtube://"]]) {
[[UIApplication sharedApplication] openURL:[NSURL URLWithString:@"youtube://profile/FlawlessFaceandBody"]];
}
else {
[[UIApplication sharedApplication] openURL:[NSURL URLWithString:@"https://www.youtube.com/user/FlawlessFaceandBody"]];
NSLog(@"No YT APP");
}
[self homepage];
}
return YES;
}
return YES;
}
此外,在此之后,我将尝试从UIWebView打开不同的选定链接并将其传递给Safari,我希望您也可以为此提供答案。
谢谢!

您是否有过在系统日志中看到此类错误“此应用程序不允许查询方案xxx”的经历?我猜Youtube和Instagram不在你的白名单中。您可以通过观察在不在白名单中的网址上调用“canOpenURL
”方法进行检查,它会返回“NO
”,即使如您所说,安装了Instagram和Youtube您的手机。我希望这会对你有所帮助。

您确定YouTube应用有" youtube://"网址类型,或者如果有,也许YouTube应用程序有另一种解析方式" youtube:// profile / ****" ?
抱歉我的英文=)

终于找到了解决方案:
的YouTube:
[[UIApplication sharedApplication] openURL:[NSURL URLWithString:@"youtube://www.youtube.com/user/FlawlessFaceandBody"]];
Instagram的:
[[UIApplication sharedApplication] openURL:[NSURL URLWithString:@"instagram://user?username=myflawless"]];
另外,对于Instagram,您可以在以下链接中找到其他URL方案:
