如何在iPhone上以编程方式拨打电话?我尝试了以下代码但没有发生任何事情:
NSString *phoneNumber = mymobileNO.titleLabel.text;
[[UIApplication sharedApplication] openURL:[NSURL URLWithString:phoneNumber]];

要返回原始应用程序,您可以使用telprompt://而不是tel:// - tell提示符将首先提示用户,但是当调用完成后,它将返回到您的应用程序:
NSString *phoneNumber = [@"telprompt://" stringByAppendingString:mymobileNO.titleLabel.text];
[[UIApplication sharedApplication] openURL:[NSURL URLWithString:phoneNumber]];
答案 1 :(得分:189)
mymobileNO.titleLabel.text 值可能不包含方案 tel://
您的代码应如下所示:
NSString *phoneNumber = [@"tel://" stringByAppendingString:mymobileNO.titleLabel.text];
[[UIApplication sharedApplication] openURL:[NSURL URLWithString:phoneNumber]];

合并@Cristian Radu和@Craig Mellon的答案以及@ joel.d的评论,你应该这样做:
NSURL *urlOption1 = [NSURL URLWithString:[@"telprompt://" stringByAppendingString:phone]];
NSURL *urlOption2 = [NSURL URLWithString:[@"tel://" stringByAppendingString:phone]];
NSURL *targetURL = nil;
if ([UIApplication.sharedApplication canOpenURL:urlOption1]) {
targetURL = urlOption1;
} else if ([UIApplication.sharedApplication canOpenURL:urlOption2]) {
targetURL = urlOption2;
}
if (targetURL) {
if (@available(iOS 10.0, *)) {
[UIApplication.sharedApplication openURL:targetURL options:@{} completionHandler:nil];
} else {
#pragma clang diagnostic push
#pragma clang diagnostic ignored "-Wdeprecated-declarations"
[UIApplication.sharedApplication openURL:targetURL];
#pragma clang diagnostic pop
}
}
这将首先尝试使用“telprompt://”URL,如果失败,它将使用“tel://”URL。如果两者都失败了,那么您正试图在iPad或iPod Touch上拨打电话。
Swift版本:
let phone = mymobileNO.titleLabel.text
let phoneUrl = URL(string: "telprompt://\(phone)"
let phoneFallbackUrl = URL(string: "tel://\(phone)"
if(phoneUrl != nil && UIApplication.shared.canOpenUrl(phoneUrl!)) {
UIApplication.shared.open(phoneUrl!, options:[String:Any]()) { (success) in
if(!success) {
// Show an error message: Failed opening the url
}
}
} else if(phoneFallbackUrl != nil && UIApplication.shared.canOpenUrl(phoneFallbackUrl!)) {
UIApplication.shared.open(phoneFallbackUrl!, options:[String:Any]()) { (success) in
if(!success) {
// Show an error message: Failed opening the url
}
}
} else {
// Show an error message: Your device can not do phone calls.
}

这里的答案非常有效。我只是将Craig Mellon的回答转换为Swift。如果有人来寻求快速回答,这将有助于他们。
var phoneNumber: String = "telprompt://".stringByAppendingString(titleLabel.text!) // titleLabel.text has the phone number.
UIApplication.sharedApplication().openURL(NSURL(string:phoneNumber)!)

如果您正在使用Xamarin开发iOS应用程序,那么C#就相当于在您的应用程序中拨打电话:
string phoneNumber = "1231231234";
NSUrl url = new NSUrl(string.Format(@"telprompt://{0}", phoneNumber));
UIApplication.SharedApplication.OpenUrl(url);

Swift 3
let phoneNumber: String = "tel://3124235234"
UIApplication.shared.openURL(URL(string: phoneNumber)!)

在Swift 3.0中,
static func callToNumber(number:String) {
let phoneFallback = "telprompt://\(number)"
let fallbackURl = URL(string:phoneFallback)!
let phone = "tel://\(number)"
let url = URL(string:phone)!
let shared = UIApplication.shared
if(shared.canOpenURL(fallbackURl)){
shared.openURL(fallbackURl)
}else if (shared.canOpenURL(url)){
shared.openURL(url)
}else{
print("unable to open url for call")
}
}

尝试上面的Swift 3选项,但它没有用。如果您要在Swift 3上对抗iOS 10+,我认为您需要以下内容:
Swift 3(iOS 10 +):
let phoneNumber = mymobileNO.titleLabel.text
UIApplication.shared.open(URL(string: phoneNumber)!, options: [:], completionHandler: nil)
答案 9 :(得分:1)
let phone = "tel://\("1234567890")";
let url:NSURL = NSURL(string:phone)!;
UIApplication.sharedApplication().openURL(url);
答案 10 :(得分:0)
'openURL:'已被弃用:iOS 10.0中首次弃用-请改用openURL:options:completionHandler:
在Objective-c iOS 10+中使用:
NSString *phoneNumber = [@"tel://" stringByAppendingString:mymobileNO.titleLabel.text];
[[UIApplication sharedApplication] openURL:[NSURL URLWithString:phoneNumber] options:@{} completionHandler:nil];
答案 11 :(得分:0)
if let url = NSURL(string: "tel://\(number)"),
UIApplication.sharedApplication().canOpenURL(url) {
UIApplication.shared.open(url, options: [:], completionHandler: nil)
}
答案 12 :(得分:0)
使用 openurl。
要在 swift 5.1 中进行调用,只需使用以下代码:(我已在 Xcode 11 中对其进行了测试)
let phone = "1234567890"
if let callUrl = URL(string: "tel://\(phone)"), UIApplication.shared.canOpenURL(callUrl) {
UIApplication.shared.open(callUrl)
}
编辑:对于 Xcode 12.4、swift 5.3,只需使用以下内容:
UIApplication.shared.open(NSURL(string: "tel://555-123-1234")! as URL)
