使用下面的方式还是会crash，没有Avoid掉
我在application:didFinishLaunchingWithOptions:中的第一行写了：
[AvoidCrash becomeEffective];

  NSDictionary *testDict = @{@"dic0":[NSNull null],@"dic1":@[@"arr10",@"arr1",[NSNull null]]};
    [[NSUserDefaults standardUserDefaults] setValue:testDict forKey:@"testDict"];
    [[NSUserDefaults standardUserDefaults] synchronize];

[User Defaults] Attempt to set a non-property-list object {
dic0 = "";
dic1 = (
arr10,
arr1,
""
);
} as an NSUserDefaults/CFPreferences value for key testDict

有空我写个解决方案给你，可以自己添加没有拦截的crash

非常感谢，我现在是写了两个category，来把容器里的null值剔除掉；
