Three ways to make phone calls in iOS

1. In this way, if you can't return to the original application after making a call, it will stay in the address book, and you will dial directly without a prompt pop-up

NSMutableString * str=[[NSMutableString alloc] initWithFormat:@"tel:%@",@"186xxxxxxxx"];
// NSLog(@"str======%@",str);
[[UIApplication sharedApplication] openURL:[NSURL URLWithString:str]];

2. In this way, after making a call, you will return to the original program and a prompt will also pop up. This is usually used.

NSMutableString * str=[[NSMutableString alloc] initWithFormat:@"tel:%@",@"186xxxxxxxx"];
UIWebView * callWebview = [[UIWebView alloc] init];
[callWebview loadRequest:[NSURLRequest requestWithURL:[NSURL URLWithString:str]]];
[ addSubview:callWebview];

3. This way, you will also go back to the original program (note the telprompt here), and a prompt will also pop up.

NSMutableString * str=[[NSMutableString alloc] initWithFormat:@"telprompt://%@",@"186xxxxxxxx"];
// NSLog(@"str======%@",str);
[[UIApplication sharedApplication] openURL:[NSURL URLWithString:str]]
