无法在Whatsapp上分享文字

Question

我正在使用以下代码从我的iOS应用程序分享WhatsApp上的文本.

        NSString *textToSend = [NSString stringWithFormat:@"whatsapp://send?text=%@", self.theTextView.text];
        NSURL *whatsappURL = [NSURL URLWithString:textToSend];

        if ([[UIApplication sharedApplication] canOpenURL: whatsappURL]) {
            [[UIApplication sharedApplication] openURL: whatsappURL];
        }else{
            [[[UIAlertView alloc] initWithTitle:nil message:@"Whatsapp not isntalled on this device! Please install first." delegate:nil cancelButtonTitle:@"Okay" otherButtonTitles:nil, nil]show];
        }

这没有按预期工作.

如果我喜欢这里解释它可以正常工作.

        NSURL *whatsappURL = [NSURL URLWithString:@"whatsapp://send?text=Hello%2C%20World!"];

Matteo Pacini您的回答不正确,

你必须添加PercentEscapes(stringByAddingPercentEscapesUsingEncoding:)NOT REPLACE PercentEscapes(stringByReplacingPercentEscapesUsingEncoding:)

string = [string stringByAddingPercentEscapesUsingEncoding:NSUTF8StringEncoding];
