快照未渲染的视图会导致空快照。确保您的视图在屏幕更新后的快照或快照之前至少呈现一次。

Snapshotting a view that has not been rendered results in an empty snapshot. Ensure your view has been rendered at least once before snapshotting or snapshot after screen updates.

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。

推荐答案

您需要设置 LSApplicationQueriesSchemes in plist如果没有设置：

You need to set LSApplicationQueriesSchemes in plist if not set:

赞，

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

</array> 

另请注意 openURL（_ :) 在iOS 10中已弃用。

Also, note that openURL(_:) is deprecated in iOS 10.

新的UIApplication方法openURL：options：completionHandler：，其中
是异步执行的，并在主队列上调用指定的完成处理程序
（此方法替换openURL :)。

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）。使用空字典表示与 openURL：相同的行为。

An options dictionary (see below for valid entries). Use an empty dictionary for the same behaviour as openURL:.

在主队列上调用完成处理程序随着成功。 Nullable 如果您对状态不感兴趣。

completion handler called on the main queue with the success. Nullable if you are not interested in the status.

比如，

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

示例：

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);
  }

(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];

  }

}
