求教如何hook 下面的安装包

安装后 打开iGrimace 会跳转到下面的页面,我想hook,不让执行该跳转。

我的代码
tweak.xm内容

#import <Foundation/Foundation.h>
#import <UIKit/UIKit.h>

%hook AppDelegate

-(BOOL)application:(id)arg1 didFinishLaunchingWithOptions:(id)arg2{
    //%orig;
UIAlertView *alert = [UIAlertView alloc] initWithTitle:@"hello first tweak"
        message:nil delegate:nil cancelButtonTitle:@"ok" otherButtonTitles:nil];
        [alert show];
        [alert release];
    return YES;
}
- (void)applicationWillResignActive:(id)arg1{
    UIAlertView *alert = [UIAlertView alloc] initWithTitle:@"applicationWillResignActive"
        message:nil delegate:nil cancelButtonTitle:@"ok" otherButtonTitles:nil];
        [alert show];
        [alert release];
    
}
- (void)applicationDidBecomeActive:(id)arg1{
 UIAlertView *alert = [UIAlertView alloc] initWithTitle:@"applicationDidBecomeActive"
        message:nil delegate:nil cancelButtonTitle:@"ok" otherButtonTitles:nil];
        [alert show];
        [alert release];
}
- (void)applicationWillEnterForeground:(id)arg1{
UIAlertView *alert = [UIAlertView alloc] initWithTitle:@"applicationWillEnterForeground"
        message:nil delegate:nil cancelButtonTitle:@"ok" otherButtonTitles:nil];
        [alert show];
        [alert release];
}
- (void)applicationDidEnterBackground:(id)arg1{
UIAlertView *alert = [UIAlertView alloc] initWithTitle:@"applicationDidEnterBackground"
        message:nil delegate:nil cancelButtonTitle:@"ok" otherButtonTitles:nil];
        [alert show];
        [alert release];
}
- (void)cxx_destruct{
UIAlertView *alert = [UIAlertView alloc] initWithTitle:@"cxx_destruct"
        message:nil delegate:nil cancelButtonTitle:@"ok" otherButtonTitles:nil];
        [alert show];
        [alert release];
}
- (void)applicationWillTerminate:(id)arg1{
    UIAlertView *alert = [UIAlertView alloc] initWithTitle:@"applicationWillTerminate"
        message:nil delegate:nil cancelButtonTitle:@"ok" otherButtonTitles:nil];
        [alert show];
        [alert release];
}
%end

plist内容
如图plist

打开都没效果,好像没hook
已经困了一个星期了,跪求大神啊

这个App是以root权限运行的,直接用CydiaSubstrate的话没法hook,应该是有可以绕过去的方法,但我不大清楚
