希望它能工作

NSString *str = @"http://r.yoz.io/PJ.c.d?";//video url 

str = [NSString stringWithFormat:@"%@id=%@",str]; 
str = [str stringByReplacingPercentEscapesUsingEncoding:NSUTF8StringEncoding]; 

CFStringRef originalURLString = (__bridge CFStringRef)[NSString stringWithFormat:@"%@",str]; 
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]; 

if ([[UIApplication sharedApplication] canOpenURL:[NSURL URLWithString:whatsAppURLString]]) 
{ 
    [[UIApplication sharedApplication] openURL:[NSURL URLWithString:whatsAppURLString]]; 
} 
else 
{ 
    UIAlertView *warningAlert = [[UIAlertView alloc] initWithTitle:@"Error" message:@"Your device has no WhatsApp installed" delegate:nil cancelButtonTitle:@"OK" otherButtonTitles:nil]; 
    [warningAlert show]; 
}
