1,这种方法,拨打完电话回不到原来的应用,会停留在通讯录里,而且是直接拨打,不弹出提示
NSMutableString * str=[[NSMutableString alloc] initWithFormat:@”tel:%@”,@”186xxxx6979”];
// NSLog(@”str======%@”,str);
[[UIApplication sharedApplication] openURL:[NSURL URLWithString:str]];

2,这种方法,打完电话后还会回到原来的程序,也会弹出提示,推荐这种
NSMutableString * str=[[NSMutableString alloc] initWithFormat:@”tel:%@”,@”186xxxx6979”];
UIWebView * callWebview = [[UIWebView alloc] init];
[callWebview loadRequest:[NSURLRequest requestWithURL:[NSURL URLWithString:str]]];
[self.view addSubview:callWebview];
[callWebview release];
[str release];

3,这种方法也会回去到原来的程序里(注意这里的telprompt),也会弹出提示
NSMutableString * str=[[NSMutableString alloc] initWithFormat:@”telprompt://%@”,@”186xxxx6979”];
// NSLog(@”str======%@”,str);
[[UIApplication sharedApplication] openURL:[NSURL URLWithString:str]]
