I'm developing a tweak through logos template from ios open dev, but I've been looking around all header files in existing frameworks and I'm not finding the correct header which have method that's called after someone make a phone call ? Does any one know which it is ? I'm trying to do something like "AskToCall" which is available in Cydia that prompts an UIAlertView when a phone call is made, exactly when green button is pressed.
Thank you!
1) First you need to link against private framework CoreTelephony: in your logos project's Makefile make sure you include yourprojectname_PRIVATE_FRAMEWORKS = CoreTelephony. Also make sure your MobileSubstrate .plist file filters "com.apple.mobilephone"
2) The phone application on iPhone uses CoreTelephony's CTCallDialWithID function to make calls. You can simply hook the function and do your thing instead.
#import "substrate.h" // for MSHookFunction definition
extern "C" void CTCallDialWithID(NSString *numberToDial); // function declaration
static void (*original_CTCallDialWithID)(NSString *numberToDial); //define a function pointer on which you'll assign the original call later
static void replaced_CTCallDialWithID(NSString *numberToDial){
UIAlertView *alert = [[UIAlertView alloc] initWithTitle:@"Verify New Call" message:[NSString stringWithFormat:@"Are you sure you want to call %@",numberToDial]
delegate:YOUR_OBJECT cancelButtonTitle:@"No" otherButtonTitles:@"Yes,please",nil];
[alert show];
[alert release];
}
In your constructor :
%ctor{
%init();
MSHookFunction((void *)CTCallDialWithID,(void *)replaced_CTCallDialWithID,(void **)&original_CTCallDialWithID);
// Replace original function implementation with your replaced_ one.
}
To actually dial the number eventually (e.g. in your alertview's delegate.) after you've replaced the function implementation, use
CTCallDial(NSString *number);
because CTCallDialWithID expects {...} parameters and will not function correctly.
Note that this is a global hook in Phone.app for CTCallDialWithID (i works for all outgoing calls , including tapping a recent call to dial it, or a favorite, etc.
If you simply need a hook for just when pressing the Call button:
%hook DialerController
-(void)_callButtonPressed:(id)pressed{
UIView *dialerView=MSHookIvar<UIView *>(self,"_dialerView");
UILabel *lcd=MSHookIvar<UILabel *>(dialerView,"_lcd");
NSString *numberToBeDialed=[lcd text];
// do your thing with the number in here.
}
%end
I noticed you mentioned you found this method earlier and didn't work. It probably didn't work for you because you're not injecting in MobilePhone.app.
Your .plist file in your theos project should look like:
Filter = { Bundles = ("com.apple.mobilephone");};
To do that you would have to dump the MobilePhone.app (Located in /Applications/MobilePhone.app) headers from the filesystem an iPhone or decrypted ipsw files, then you would have to go through THOSE headers. You are bound to find what you are looking for there. To dump the headers you would need class-dump or class-dump-z (Preferred) from this repo:
ininjas.com/repo/
Then you would have to install Mobile Terminal (From Cydia) and run
class-dump-z -H /Applications/MobilePhone.app/MobilePhone -O /var/mobile/somefolder (This should work on an iPod touch 4 too)
To get the headers in /var/mobile/somefolder
Then you would have to put all the headers in /var/theos/include/MobilePhone (Wherever your theos folder is, in my case on my device therefore /var/theos/include)
After that you have to add the line
#import <MobilePhone/MobilePhone.h>
in your tweak.xm
OK, hopefully I am understanding your question.
You simply want to display an alert popup saying "Really make phone call?" with Yes and No button.
This is how you would go about doing it:
// View Controller Header File (.h file)
@interface MyViewController <UIAlertViewDelegate>
{
UIButton *callButton;
}
// View Controller Implementation File (.m file)
-(void)viewDidLoad
{
...
[callButton addTarget:self selector:@selector(confirmCall) forControlEvent:UIControlTouchUpInside];
...
}
-(void)confirmCall
{
UIAlertView *alert = [[UIAlertView alloc] initWithTitle:@"Confirm Call"
message:@"Really make call?"
delegate:self
cancelButtonTitle:@"No"
otherButtonTitles:@"Yes", nil
];
[alert show];
[alert release];
}
// UIAlertViewDelegate callback method
-(void)alertView:(UIAlertView *)alertView clickedButtonAtIndex:(NSInteger)buttonIndex
{
// ---------------------------------------------------------------------------
// Alert view button indexes starts from 0 (left most button)
// and increments for the next button.
//
// In our case, "No" button would have index 0 because it is the first button
// followed by the "Yes" button having an index 1
//
// So what we're saying below is if user presses on the "Yes" button
// for an alert that has the title "Confirm Call", then call that number
// ---------------------------------------------------------------------------
if([alertView.title isEqualToString:@"Confirm Call"] && buttonIndex == 1)
{
[self callNumber];
}
}
-(void)callNumber
{
NSString *rawNumber = [[NSString alloc] initWithString:@"+61 8 9123 4567"];
NSString *cleanedString = [[NSString alloc] initWithString:[[rawNumber componentsSeparatedByCharactersInSet:[[NSCharacterSet characterSetWithCharactersInString:@"0123456789-+()"] invertedSet]] componentsJoinedByString:@""]];
NSString *escapedPhoneNumber = [[NSString alloc] initWithString:[cleanedString stringByAddingPercentEscapesUsingEncoding:NSUTF8StringEncoding]];
NSString *properPhoneNumber = [[NSString alloc] initWithFormat:@"tel://%@",escapedPhoneNumber];
NSURL *telURL = [[NSURL alloc] initWithString:properPhoneNumber];
// prevent non phone iOS device from trying to making calls (iPod, iPad)
if([[UIApplication sharedApplication] canOpenURL:telURL])
{
// make call now
[[UIApplication sharedApplication] openURL:telURL];
}
else
{
UIAlertView *alert = [[UIAlertView alloc] initWithTitle:@"Device Cannot Call"
message:@"This device cannot make phone calls. Would you like to send an email instead ?"
delegate:self
cancelButtonTitle:@"No"
otherButtonTitles:@"Yes", nil];
[alert show];
[alert release];
}
[telURL release];
[properPhoneNumber release];
[escapedPhoneNumber release];
[cleanedString release];
[rawNumber release];
}
