1，這種方法，撥打完電話回不到原來的應用，會停留在通訊錄里，而且是直接撥打，不彈出提示

NSMutableString* str=[[NSMutableStringalloc]initWithFormat:@"tel:%@",@"186xxxx6979"];//??????????? NSLog(@"str======%@",str);[[UIApplication sharedApplication] openURL:[NSURL URLWithString:str]];

2，這種方法，打完電話后還會回到原來的程序，也會彈出提示，推薦這種

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

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

[self.viewaddSubview:callWebview];

[callWebviewrelease];

[strrelease];

3,這種方法也會回去到原來的程序里（注意這里的telprompt），也會彈出提示

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

44.。推薦推薦

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

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

}];
