Please note, this answer works with numeric data types (int, long). If you are starting with a string, you’ll need to convert it to a number first. Also, please take into account that you’ll need to validate that the initial string is at least 10 characters in length. From a good page full of examples: … Read more
This will help you Format (xxx) xxx-xxxx – (BOOL)textField:(UITextField *)textField shouldChangeCharactersInRange:(NSRange)range replacementString:(NSString *)string { int length = (int)[self getLength:textField.text]; //NSLog(@”Length = %d “,length); if(length == 10) { if(range.length == 0) return NO; } if(length == 3) { NSString *num = [self formatNumber:textField.text]; textField.text = [NSString stringWithFormat:@”(%@) “,num]; if(range.length > 0) textField.text = [NSString stringWithFormat:@”%@”,[num substringToIndex:3]]; … Read more
Just try: if let url = NSURL(string: “tel://\(busPhone)”) where UIApplication.sharedApplication().canOpenURL(url) { UIApplication.sharedApplication().openURL(url) } assuming that the phone number is in busPhone. NSURL‘s init(string:) returns an Optional, so by using if let we make sure that url is a NSURL (and not a NSURL? as returned by the init). For Swift 3: if let url = … Read more
Two ways to achieve it. 1) Need to start the dialer via code, without user interaction. You need Action_Dial, use below code it will open Dialer with number specified Intent intent = new Intent(Intent.ACTION_DIAL); intent.setData(Uri.parse(“tel:0123456789”)); startActivity(intent); The ‘tel:’ prefix is required, otherwhise the following exception will be thrown: java.lang.IllegalStateException: Could not execute method of the … Read more
Following code shows an easy way to read all phone numbers and names: Cursor phones = getContentResolver().query(ContactsContract.CommonDataKinds.Phone.CONTENT_URI, null,null,null, null); while (phones.moveToNext()) { String name=phones.getString(phones.getColumnIndex(ContactsContract.CommonDataKinds.Phone.DISPLAY_NAME)); String phoneNumber = phones.getString(phones.getColumnIndex(ContactsContract.CommonDataKinds.Phone.NUMBER)); } phones.close(); NOTE: getContentResolver is a method from the Activity context.
Use String. Aside from anything else, you won’t be able to store leading zeroes if you use integers. You definitely shouldn’t use int (too small) float or double (too much risk of data loss – see below); long or BigInteger could be appropriate (aside from the leading zeroes problem), but frankly I’d go with String. … Read more
The tel: scheme was used in the late 1990s and documented in early 2000 with RFC 2806 (which was obsoleted by the more-thorough RFC 3966 in 2004) and continues to be improved. Supporting tel: on the iPhone was not an arbitrary decision. callto:, while supported by Skype, is not a standard and should be avoided … Read more
Code: TelephonyManager tMgr = (TelephonyManager)mAppContext.getSystemService(Context.TELEPHONY_SERVICE); String mPhoneNumber = tMgr.getLine1Number(); Required Permission: <uses-permission android:name=”android.permission.READ_PHONE_STATE”/> Caveats: According to the highly upvoted comments, there are a few caveats to be aware of. This can return null or “” or even “???????”, and it can return a stale phone number that is no longer valid. If you want something … Read more
Better option… just strip all non-digit characters on input (except ‘x’ and leading ‘+’ signs), taking care because of the British tendency to write numbers in the non-standard form +44 (0) … when asked to use the international prefix (in that specific case, you should discard the (0) entirely). Then, you end up with values … Read more
I have some insight into the matter for you. The MSISDN can be stored on the SIM card, however most network providers (all providers in South Africa) do not store the MSISDN on the SIM card. There are several reasons for this, the most notable being: Dynamic MSISDN allocation: Prepaid SIMs are sometime allocated an … Read more
