我理解是无返回值,一个BOOL和一个id型参数
-(void)method1:(id)arg1 method2:(id)arg2 method3:(id)arg3 method4:(void(^)(BOOL,id))arg4 {
NSLog(@"MyHook1 \narg1:%@\narg2:%@\narg3:%@\narg4:%@\n",arg1,arg2,arg3,arg4);
id myArg4 = ^(BOOL block_arg1, id block_arg2){
NSLog(@"MyHook2 %@",block_arg2);
arg4(block_arg1,block_arg2);
NSLog(@"MyHook3 arg4 completed");
};
%orig(arg1,arg2,arg3,myArg4);
}
输出MyHook1 和 MyHook2就crash,这个hook应该怎样写呢?block还是没全搞懂
https://github.com/AloneMonkey/MonkeyDev/issues/125 和这个例子一模一样,而且我还试着try/catch, 以为有什么exception,没有任何输出,直接闪退/crash
难道上面的参数不对?
