iOS 10中的Whatsapp集成和openURL问题

标签: ios objective-c ios10 whatsapp openurl

我已经在我的iOS应用中集成了whastapp。当我在iOS 10设备上测试它时。它崩溃了一个问题。

快照未呈现的视图会导致空快照。确保在屏幕更新后快照或快照之前,您的视图至少呈现过一次。

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。

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

像,

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

</array> 

另请注意,iOS 10中已弃用openURL(_:)

  

新的UIApplication方法openURL:options:completionHandler:,其中   以异步方式执行并调用指定的完成处理程序   在主队列上(此方法替换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:

  • URL打开

  • 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。

  • 完成处理程序在主队列上调用成功。如果您对状态不感兴趣,请Nullable

像,

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);
  }

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];

  }

}
