我在这个应用程序中使用这些代码进行共享应用程序链接，但是whatsapp的文本域中没有任何内容。如果使用简单的文本然后它的工作。任何人都可以建议最终结果。

I used these code for share app link in what's app but nothing is come in the textfield of whatsapp. If using simple text then its work. Can anyone suggest the final outcome.

NSString *theTempMessage = @"whatsapp://send?text=https://itunes.apple.com/in/app/myapp/id1054375332?ls=1&mt=8";
NSString *theFinalMessage;

theTempMessage = [theTempMessage stringByReplacingOccurrencesOfString:@":" withString:@"%3A"];
theTempMessage = [theTempMessage stringByReplacingOccurrencesOfString:@"/" withString:@"%2F"];
theTempMessage = [theTempMessage stringByReplacingOccurrencesOfString:@"?" withString:@"%3F"];
theTempMessage = [theTempMessage stringByReplacingOccurrencesOfString:@"," withString:@"%2C"];
theTempMessage = [theTempMessage stringByReplacingOccurrencesOfString:@"=" withString:@"%3D"];
theFinalMessage = [theTempMessage stringByReplacingOccurrencesOfString:@"&" withString:@"%26"];

NSString * stringToSend=theFinalMessage;
NSURL *whatsappURL = [NSURL URLWithString:stringToSend];

if ([[UIApplication sharedApplication] canOpenURL: whatsappURL])

{
    [[UIApplication sharedApplication] openURL: whatsappURL];
}

推荐答案

检查时出现以下错误 canOpenURL

网址失败：whatsapp：// - 错误：此应用不允许查询方案whatsapp

failed for URL: "whatsapp://" - error: This app is not allowed to query for scheme whatsapp

在iOS 9中，您必须将应用想要在Info.plist中查询的任何URL方案列入白名单LSApplicationQueriesSchemes键（一个字符串数组）：

In iOS 9 you must whitelist any URL schemes your App wants to query in Info.plist under the LSApplicationQueriesSchemes key (an array of strings):

使用Info.plist中包含的方案，一切都像以前一样有效。当您链接iOS 9时，您不仅限于50个不同的方案，您只需要在Info.plist中声明您需要的内容。您可以包含多少计划似乎没有限制，但如果他们认为您滥用该机制，我会期待App Store审核小组提出的问题。

With the schemes included in Info.plist everything works as before. When you link against iOS 9 you are not limited to 50 distinct schemes you just need to declare what you need in Info.plist. There seems to be no limit for how many schemes you can include but I would expect questions from the App Store review team if they think you are abusing the mechanism.

请注意，此机制仅适用于canOpenURL而不适用于openURL。
你不需要在Info.plist中列出一个方案就能用
用openURL打开它。

Note that this mechanism only applies to canOpenURL and not openURL. You do not need to have a scheme listed in Info.plist to be able to open it with openURL.

NSString * msg = @"Application%20Name%20https://itunes.apple.com/in/app/myapp/id1054375332?ls=1&mt=8";

msg = [msg stringByReplacingOccurrencesOfString:@":" withString:@"%3A"];
msg = [msg stringByReplacingOccurrencesOfString:@"/" withString:@"%2F"];
msg = [msg stringByReplacingOccurrencesOfString:@"?" withString:@"%3F"];
msg = [msg stringByReplacingOccurrencesOfString:@"," withString:@"%2C"];
msg = [msg stringByReplacingOccurrencesOfString:@"=" withString:@"%3D"];
msg = [msg stringByReplacingOccurrencesOfString:@"&" withString:@"%26"];

NSString * urlWhats = [NSString stringWithFormat:@"whatsapp://send?text=%@",msg];
NSURL * whatsappURL = [NSURL URLWithString:urlWhats];

if ([[UIApplication sharedApplication] canOpenURL: whatsappURL]) {
    [[UIApplication sharedApplication] openURL: whatsappURL];
} else {
    UIAlertView * alert = [[UIAlertView alloc] initWithTitle:@"WhatsApp not installed." message:@"Your device has no WhatsApp installed." delegate:self cancelButtonTitle:@"OK" otherButtonTitles:nil];
    [alert show];
}
