ios - iOS 10 中的 Whatsapp 集成和 openURL 问题

Question

我已将 whastapp 集成到我的 iOS 应用程序中。当我在我的 iOS 10 设备上测试它时。它因问题而崩溃。

对尚未渲染的 View 进行快照会生成空快照。确保您的 View 在屏幕更新之前或快照之前至少被渲染过一次。

NSURL *whatsappURL = [NSURL URLWithString:[NSString stringWithFormat: @"whatsapp://send?abid=%@&text=WelcomeToChatBought",[abidArray objectAtIndex:buttonclicked.tag-1000]]];
        if ([[UIApplication sharedApplication] canOpenURL: whatsappURL])
        {
            [[UIApplication sharedApplication] openURL: whatsappURL];
        }

可能是什么问题。任何帮助将不胜感激。

Answer 1

如果未设置，则需要在 plist 中设置 LSApplicationQueriesSchemes:

喜欢，

<key>LSApplicationQueriesSchemes</key>
<array>
 <string>urlscheme1</string>
 <string>urlscheme2</string>

</array> 

另外，请注意 openURL(_:)在 iOS 10 中已弃用。

The new UIApplication method openURL:options:completionHandler:, which is executed asynchronously and calls the specified completion handler on the main queue (this method replaces openURL:).

iOS 10 中的新方法:

- (void)openURL:(NSURL*)url options:(NSDictionary<NSString *, id> *)options
  completionHandler:(void (^ __nullable)(BOOL success))completion

参数:

• 要打开的URL

• 选项字典(有效条目见下文)。对于与 openURL: 相同的行为，使用空字典。

• 成功调用主队列的完成处理程序。 Nullable 如果您对状态不感兴趣。

喜欢，

UIApplication *application = [UIApplication sharedApplication];
[application openURL:URL options:@{} completionHandler:nil];

例子:

NSString *scheme=[NSString stringWithFormat: @"whatsapp://send?abid=%@&text=WelcomeToChatBought",[abidArray objectAtIndex:buttonclicked.tag-1000]]];

  UIApplication *application = [UIApplication sharedApplication];
  NSURL *URL = [NSURL URLWithString:scheme];

  if ([application respondsToSelector:@selector(openURL:options:completionHandler:)]) {
    [application openURL:URL options:@{}
       completionHandler:^(BOOL success) {
      NSLog(@"Open %@: %d",scheme,success);
    }];
  } else {
    BOOL success = [application openURL:URL];
    NSLog(@"Open %@: %d",scheme,success);
  }

编辑:(基于iOS版本的代码)

NSURL *URL = [NSURL URLWithString:strUrl];

if([[UIDevice currentDevice].systemVersion floatValue] >= 10.0){

  if ([application respondsToSelector:@selector(openURL:options:completionHandler:)]) {
    [application openURL:URL options:@{}
       completionHandler:^(BOOL success) {
      NSLog(@"Open %@: %d",scheme,success);
    }];
  } else {
    BOOL success = [application openURL:URL];
    NSLog(@"Open %@: %d",scheme,success);
  }


}
else{

  bool can = [[UIApplication sharedApplication] canOpenURL:URL];

  if(can){

     [[UIApplication sharedApplication] openURL:URL];

  }

}
