Dynamically Generated iOS Headers

Here are iOS Objective-C headers as derived from runtime introspection.

The headers were generated using RuntimeBrowser for iPhone.


You can search the headers with github search:


You can compare versions based on their tags, see the tags page:

$ git difftool 6.0 6.1 .

Sample usage

You can use the headers this way:

NSBundle *b = [NSBundle bundleWithPath:@"/System/Library/PrivateFrameworks/FTServices.framework"];
BOOL success = [b load];

Class FTDeviceSupport = NSClassFromString(@"FTDeviceSupport");
id si = [FTDeviceSupport valueForKey:@"sharedInstance"];

NSLog(@"-- %@", [si valueForKey:@"deviceColor"]);

  • Red == private
  • Blue == dylib
