1每篷，這種方法，撥打完電話回不到原來的應(yīng)用端圈，會停留在通訊錄里焦读，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舱权，這種方法矗晃，打完電話后還會回到原來的程序，也會彈出提示宴倍，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）张症，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);
}];
