这里给出核心的hook代码，具体见
#import "CaptainHook.h"#import#import//Hook的class
CHDeclareClass(AttendanceViewController);
//Hook的函数
//-(void)checkButton:(int)button;
CHMethod(1, void, AttendanceViewController, checkButton, int, button)
{
if (button == 2) {
CLLocationCoordinate2D coordinate;
coordinate.latitude = 30.183031 + (rand()%10)/10000.0;
coordinate.longitude = 120.1722623 + (rand()%10)/10000.0;
CLLocation *newLocation = [[CLLocation alloc]initWithLatitude:coordinate.latitude longitude:coordinate.longitude];
[self setValue:newLocation forKey:@"locationUser"]; //Use kvc set new value
UIAlertView *testAlert = [[UIAlertView alloc] initWithTitle:@"Haha~" message:@"打卡成功啰" delegate:self
cancelButtonTitle:@"OK" otherButtonTitles:nil];
[testAlert show];
}
CHSuper(1, AttendanceViewController, checkButton, button);
}
__attribute__((constructor)) static void entry()
{
CHLoadLateClass(AttendanceViewController);
CHClassHook(1, AttendanceViewController, checkButton);
}
