log('SecKeyEncrypt called from:\n' +
Thread.backtrace(this.context, Backtracer.ACCURATE)
.map(DebugSymbol.fromAddress).join('\n') + '\n');

onEnter(log, args, state) {
log(`SecKeyRawSign()=${args.readCString()}=`);
log('SecKeyRawSign called from:\n' +

},
onLeave(log, retval, state) {
}
}7、修改方法的入参

log(`[${self.$className} ${method}]`);
// 字符串
// var str = ObjC.classes.NSString.stringWithString_("hi wit!")// 对应的oc语法：NSString *str = ;
// args = str// 修改入参为字符串
// 数组
// var array = ObjC.classes.NSMutableArray.array();// 对应的oc语法：NSMutableArray array = ;
// array.addObject_("item1");// 对应的oc语法：;
// array.addObject_("item2");// 对应的oc语法：;

// dictionary.setObject_forKey_("value1", "key1"); // 对应的oc语法：
// dictionary.setObject_forKey_("value2", "key2"); // 对应的oc语法：
// args = dictionary; // 修改入参为字典
// 字节
var data = ObjC.classes.NSMutableData.data(); // 对应的oc语法：NSMutableData *data = ;
var str = ObjC.classes.NSString.stringWithString_("hi wit!")// 获取一个字符串。 对应的oc语法：NSString *str = ;
var subData = str.dataUsingEncoding_(4);// 将str转换为data,编码为utf-8。对应的oc语法：NSData *subData = ;
data.appendData_(subData);// 将subData添加到data。对应的oc语法：;
args = data; // 修改入参字段

},
onLeave(log, retval, state) {
// 字符串
var str = ObjC.classes.NSString.stringWithString_("hi wit!")// 对应的oc语法：NSString *str = ;
retval.replace(str)// 修改返回值
var after = new ObjC.Object(retval); // 打印出来是个指针时，请用该方式转换后再打印
log(`before:=${retval}=`);
log(`after:=${after}=`);
}
}9、打印字符串、数组、字典
frida-trace -UF -m "-"
js代码如下：
{
onEnter(log, args, state) {
var self = new ObjC.Object(args);// 当前对象
var method = args.readUtf8String();// 当前方法名
log(`[${self.$className} ${method}]`);
var before = args;
// 注意，日志输出请直接使用log函数。不要使用console.log()
var after = new ObjC.Object(args); // 打印出来是个指针时，请用该方式转换后再打印
log(`before:=${before}=`);
log(`after:=${after}=`);
},
onLeave(log, retval, state) {
}
}10、打印NSData

onEnter(log, args, state) {
var self = new ObjC.Object(args);// 当前对象
var method = args.readUtf8String();// 当前方法名
log(`[${self.$className} ${method}]`);
var before = args;
// 注意，日志输出请直接使用log函数。不要使用console.log()
var after = new ObjC.Object(args); // 打印NSData
var outValue = after.bytes().readUtf8String(after.length()) // 将data转换为string
log(`before:=${before}=`);
log(`after:=${outValue}=`);

// 打印该对象所有属性
var ivarList = customObj.$ivars;
for (key in ivarList) {
log(`key${key}=${ivarList}=`);
}
// 打印该对象所有方法
var methodList = customObj.$methods;
for (var i=0; i<methodList.length; i++) {
log(`method=${methodList}=`);
}
},
onLeave(log, retval, state) {
}
