In order to return to app after call, I use telprompt instead of tel. Codes like this:
[[UIApplication sharedApplication] openURL:[NSURL URLWithString:@"telprompt://10086"]];
Somebody says that it will be rejected by apple because telpromt is not the public URL Scheme. But I didn't find a certain answer - Yes or No. Can anybody help me?
You may want to have a look at handleopenurl.com an index for iOS URL schemes.
I do not know telprompt. Why not just use tel://10086?
