How to share content on WhatsApp from iOS

问题

I would like to share one Url link and some text message into WhatsApp from my application. How can i share content?

I got this code for only text

NSString * msg = @"Trueman India Magazine";
NSString * urlWhats = [NSString stringWithFormat:@"whatsapp://send?text=%@",msg];
NSURL * whatsappURL = [NSURL URLWithString:[urlWhats stringByAddingPercentEscapesUsingEncoding:NSUTF8StringEncoding]];

if ([[UIApplication sharedApplication] canOpenURL: whatsappURL])
    {
        [[UIApplication sharedApplication] openURL: whatsappURL];
    }

but how i share my url link in WhatsApp?

回答1:

Include the plain link inside the text, e.g.:

NSString * msg = @"Trueman India Magazine http://www.truemanindiamagazine.com";

The link will be generated/tappable after sending it to someone

I had a problem with this whatsapp api with url strings, especially when they contained a query string with several fields, e.g. http://example.com/foo?bar=foo&foo=bar. When opening the app I found the message text would be empty.

The solution was to properly percent escape the string using the CFString functions. See the apple documentation here: https://developer.apple.com/library/mac/documentation/CoreFoundation/Reference/CFURLRef/index.html#//apple_ref/c/func/CFURLCreateStringByAddingPercentEscapes

But for anyone else with this issue here is my solution in full:

CFStringRef originalURLString = (__bridge CFStringRef)[NSString stringWithFormat:@"%@", @"http://example.com/foo?bar=foo&foo=bar"];
CFStringRef preprocessedURLString = CFURLCreateStringByReplacingPercentEscapesUsingEncoding(kCFAllocatorDefault, originalURLString, CFSTR(""), kCFStringEncodingUTF8);
NSString *urlString = (__bridge NSString*)CFURLCreateStringByAddingPercentEscapes(kCFAllocatorDefault, preprocessedURLString, NULL, CFSTR("!*'();:@&=+$,/?%#[]"), kCFStringEncodingUTF8);
NSString *whatsAppURLString = [NSString stringWithFormat:@"whatsapp://send?text=%@", urlString];
[[UIApplication sharedApplication] openURL:[NSURL URLWithString:whatsAppURLString]];

Note the use of the characters to be escaped in the CFURLCreateStringByAddingPercentEscapes function.
