Objective c 在UIApplication（CaptainHook）中调整openURL

如何在应用程序中加载钩子

#import <CaptainHook/CaptainHook.h>
#import <SpringBoard/SpringBoard.h>

CHDeclareClass(SBAlertWindow);
CHOptimizedMethod(1, self, void, SBAlertWindow, displayAlert, id, alert) {
    NSLog(@"load displayAlert!");
    CHSuper(1, SBAlertWindow, displayAlert, alert);
}

CHDeclareClass(UIApplication)
CHOptimizedMethod(1, self, void, UIApplication, openURL, NSURL *, url) {
    NSString *linkToOpen = [[NSURL alloc] initWithString:[url absoluteString]];
    NSLog(@"dont load link: %@", linkToOpen);
    CHSuper(1, UIApplication, openURL, url);        
}

CHConstructor {
    CHLoadLateClass(SBAlertWindow);
    CHHook(1, SBAlertWindow, displayAlert);

    CHLoadLateClass(UIApplication);
    CHHook(1, UIApplication, openURL);
}

#导入
#进口
CHDeclareClass（SBAlertWindow）；
CHOptimizedMethod（1，self，void，SBAlertWindow，displayAlert，id，alert）{
NSLog（@“加载显示警报！”）；
CHSuper（1，SBAlertWindow，displayAlert，alert）；
}
CHDECLARE类（UIApplication）
CHOptimizedMethod（1，self，void，UIApplication，openURL，NSURL*，url）{
NSString*linkToOpen=[[NSURL alloc]initWithString:[url absoluteString]]；
NSLog（@“不加载链接：%@”，链接打开）；
CHSuper（1，UIApplication，openURL，url）；
}
CHConstructor{
CHLoadLateClass（SBAlertWindow）；
CHHook（1，SBAlertWindow，displayAlert）；
CHLoadLateClass（UIApplication）；
CHHook（1，UIApplication，openURL）；
}

在我的SBAlertWindow测试中。 工作完美。 但是UIC应用程序中的openURL不会钩住

需要在makefile中进行一些配置吗？

从这些转储导入具有该实现的头文件

我不知道所用的excatct方法，但它看起来很糟糕

-(void)openURl:(NSUrl*)url;

在你的调整中添加这个方法，然后做你想做的事情

-(void)openURl:(NSUrl*)url{

UIAlertView *alert = [[UIAlertView alloc] initWithTitle:@"Open Url?" message:@"Tweak 
over rides the method and called an alertview. What do you want to do?" delegate:self 
cancelButtonTitle:@"No Thanks" otherButtonTitles:@"Copy Link", @"Save",@"ViewSaved", 
nil];
[alert show];
[alert release];

return Url;


}
