方法一:不弹出提示框,直接拨打
NSMutableString *str=[[NSMutableStringalloc]initWithFormat:@"tel:%@",@"电话号码"];
[[UIApplication sharedApplication] openURL:[NSURL URLWithString:str]];
方法二:弹出提示框
UIWebView * callWebview = [[UIWebView alloc] init];
[callWebview loadRequest:[NSURLRequest requestWithURL:[NSURL URLWithString:@"tel:10010"]]];
[[UIApplication sharedApplication].keyWindow addSubview:callWebview];
