iOS拨打电话的3种方式

iOS实现拨打电话的方式:

方法一、requestWithURL,此方法拨打前弹出提示

NSMutableString * string = [[ NSMutableString alloc] initWithFormat: @"tel:%@", @"136****0000"];
UIWebView * callWebview = [[ UIWebView alloc] init];
[callWebview loadRequest:[ NSURLRequest requestWithURL:[ NSURL URLWithString:string]]];
[ self.view addSubview:callWebview];

swift代码:

let callWebview = UIWebView()callWebview.loadRequest( NSURLRequest(url: URL(string: "tel:136****0000")!) as URLRequest)
self.view.addSubview(callWebview)


方法二、openURL(telprompt) ,此方法拨打前弹出提示,据说会导致App Store审核不通过

NSMutableString * string = [[ NSMutableString alloc] initWithFormat: @"telprompt:%@", @"136****0000"];
[[ UIApplication sharedApplication] openURL:[ NSURL URLWithString:string]];

swift代码:

UIApplication.shared.openURL(URL(string: "telprompt:136****0000")!)


方法三、利用openURL(tel),此方法在iOS 10.2之前不会添加弹框,需要自己处理,手动添加alert即可

NSMutableString * string = [[ NSMutableString alloc] initWithFormat: @"tel:%@", @"136****0000"];
[[ UIApplication sharedApplication] openURL:[ NSURL URLWithString:string]];

swift代码:

UIApplication.shared.openURL(URL(string: "tel:136****0000")!)
