The by 0xdea () are an excellent starting point for a base script. The 'trace' line of scripts provide prebuilt method hooking functions which greatly simplify the hooking process. There are both Android and iOS variants available. If you browse to the bottom of any of these scripts, you will see some commented out examples of how to use these scripts, included here for quick reference:
// usage examples
setTimeout(function() { // avoid java.lang.ClassNotFoundException
Java.perform(function() {
// enumerate all classes
/*
var a = enumAllClasses();
a.forEach(function(s) {
console.log(s);
});
*/
// find classes that match a pattern
/*
var a = findClasses(/password/i);
a.forEach(function(s) {
console.log(s);
});
*/
// enumerate all methods in a class
/*
var a = enumMethods("com.target.app.PasswordManager")
a.forEach(function(s) {
console.log(s);
});
*/
});
}, 0);
// usage examples
if (ObjC.available) {
// enumerate all classes
/*
var a = enumAllClasses();
a.forEach(function(s) {
console.log(s);
});
*/
// find classes that match a pattern
/*
var a = findClasses(/password/i);
a.forEach(function(s) {
console.log(s);
});
*/
// enumerate all methods in a class
/*
var a = enumMethods("PasswordManager")
a.forEach(function(s) {
console.log(s);
});
*/
// enumerate all methods
/*
var d = enumAllMethods();
for (k in d) {
console.log(k);
d[k].forEach(function(s) {
console.log("\t" + s);
});
}
*/
// find methods that match a pattern
/*
var d = findMethods(/password/i);
for (k in d) {
console.log(k);
d[k].forEach(function(s) {
console.log("\t" + s);
});
}
*/
} else {
send("error: Objective-C Runtime is not available!");
}

Once one of these scripts is , you can access thetrace methods directly from the REPL. Alternatively, you may add them directly to the raptor script. Remember, making changes to a script while it is loaded will cause Frida to reload that script.
Another great resource for scripts is "", a repo maintained by at NowSecure containing a large number of links that include: talks, papers, videos, blog posts,
