简介

Logify能够接受一个.h头文件作为输入,然后输出.xm文件(MobileSubstrate扩展),这个.xm文件hook这个类的所有方法,当这些方法被调用的时候打印log。这有助于你发现哪些方法被调用了。Logify在安装了Theos之后就有。

用法

在命令行下输入类似的命令:

/opt/theos/bin/logify.pl MomoLocationManager.h > tweak.xm

其中MomoLocationManager.h是头文件,后面的tweak.xm是自动生成的tweak文件。

在我的mac上我是这样输入的:

ZPs-MBP:momoLocation admin$ /opt/theos/bin/logify.pl MomoLocationManager.h > tweak.xm

这个tweak.xm的内容如下:

%hook MomoLocationManager
- (void)setFakeLocation:(CLLocation* )fakeLocation { %log; %orig; }
- (CLLocation* )fakeLocation { %log; CLLocation*  r = %orig; NSLog(@" = %@", r); return r; }
- (void)setReviseLocation:(CLLocation* )reviseLocation { %log; %orig; }
- (CLLocation* )reviseLocation { %log; CLLocation*  r = %orig; NSLog(@" = %@", r); return r; }
- (void)setLocation:(CLLocation* )location { %log; %orig; }
- (CLLocation* )location { %log; CLLocation*  r = %orig; NSLog(@" = %@", r); return r; }
- (void)setLastLocTime:(NSDate* )lastLocTime { %log; %orig; }
- (NSDate* )lastLocTime { %log; NSDate*  r = %orig; NSLog(@" = %@", r); return r; }
- (void)setLocManager:(CLLocationManager* )locManager { %log; %orig; }
- (CLLocationManager* )locManager { %log; CLLocationManager*  r = %orig; NSLog(@" = %@", r); return r; }
- (void)setBeginDate:(NSDate* )beginDate { %log; %orig; }
- (NSDate* )beginDate { %log; NSDate*  r = %orig; NSLog(@" = %@", r); return r; }
+(id)shareMomoLocationManager { %log; id r = %orig; NSLog(@" = %@", r); return r; }
-(id)distanceBetweenLocationDictionary:(id)dictionary { %log; id r = %orig; NSLog(@" = %@", r); return r; }
-(BOOL)isOriginLocationValid { %log; BOOL r = %orig; NSLog(@" = %d", r); return r; }
-(BOOL)isReviseLocationValid { %log; BOOL r = %orig; NSLog(@" = %d", r); return r; }
-(void)locationManager:(id)manager didFailWithError:(id)error { %log; %orig; }
-(void)locationManager:(id)manager didUpdateToLocation:(id)location fromLocation:(id)location3 { %log; %orig; }
-(void)refreshLocationIfExceedLimit { %log; %orig; }
-(void)HandleTimer { %log; %orig; }
-(void)updateServerLocation { %log; %orig; }
-(void)locationFail { %log; %orig; }
-(void)locationFinish { %log; %orig; }
-(void)updateSelfLocation:(id)location { %log; %orig; }
-(void)cancelLocation { %log; %orig; }
-(void)reviseLocationToError:(id)error { %log; %orig; }
-(void)reviseLocationToFail:(id)fail { %log; %orig; }
-(void)reviseLocationToSuccess:(id)success { %log; %orig; }
-(void)reviseLocationTo { %log; %orig; }
-(void)stoplocation { %log; %orig; }
-(void)locationTimeOut { %log; %orig; }
-(void)starLocationAndCorrectLocation:(BOOL)location { %log; %orig; }
-(id)getLatestLocationWithInterval:(double)interval { %log; id r = %orig; NSLog(@" = %@", r); return r; }
-(void)dealloc { %log; %orig; }
-(id)init { %log; id r = %orig; NSLog(@" = %@", r); return r; }
%end

使用Theos:iOS越狱程序开发框架介绍的方法编写Tweak,然后用上述生成的tweak.xm覆盖自动生成的tweak.xm文件,然后安装到设备上。

打开Xcode的Organizer看设备的log。可以得到如下的log信息:

我们可以发现有哪些方法被调用了,其中红色划线的地方,就是我们的当前位置的经纬度。

我的经纬度被上报了。

从这个图中,可以发现最终是调用了:

  • (void)setLocation:(CLLocation* )location

在下一节,我们将拦截这个方法,给这个方法传递一个假地址,看看是否能达到目的。
