IOS之拨打电话的三种方式
// 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 * str1=[[NSMutableString alloc] initWithFormat:@"tel:%@",@"13913013703"];
NSLog(@"str======%@",str);
[[UIApplication sharedApplication] openURL:[NSURL URLWithString:str1]];
//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 * str2=[[NSMutableString alloc] initWithFormat:@"tel:%@",@"13913013703"];
UIWebView * callWebview = [[UIWebView alloc] init];
[callWebview loadRequest:[NSURLRequest requestWithURL:[NSURL URLWithString:str2]]];
[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 * str3=[[NSMutableString alloc] initWithFormat:@"telprompt://%@",@"13913013703"];
NSLog(@"str======%@",str);
[[UIApplication sharedApplication] openURL:[NSURL URLWithString:str3]];
