拨打电话的功能

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=[[NSMutableStringalloc]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=[[NSMutableStringalloc]initWithFormat:@"tel:%@",@"186xxxx6979"];UIWebView* callWebview = [[UIWebViewalloc]init];

[callWebviewloadRequest:[NSURLRequestrequestWithURL:[NSURLURLWithString:str]]];

[self.viewaddSubview:callWebview];

[callWebviewrelease];

[strrelease];

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=[[NSMutableStringalloc]initWithFormat:@"telprompt://%@",@"186xxxx6979"];//            NSLog(@"str======%@",str);[[UIApplicationsharedApplication]openURL:[NSURLURLWithString:str]]

44.。推荐推荐

NSString*telephoneNumber=@"拨打的号码";NSMutableString* str=[[NSMutableStringalloc]initWithFormat:@"tel:%@",telephoneNumber];UIApplication*application = [UIApplicationsharedApplication];NSURL*URL= [NSURLURLWithString:str];

[applicationopenURL:URLoptions:@{}completionHandler:^(BOOLsuccess) {//OpenSuccess=选择 呼叫 为1选择 取消 为0NSLog(@"OpenSuccess=%d",success);

}];
