iOS 拨打电话三种方式总结

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"];

[[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"];

[[UIApplication sharedApplication] openURL:[NSURL URLWithString:str]]
