iOS開發，hook系統Objective-C的函數

我們都知道在windows下可以通過API輕鬆的hook很多訊息，IOS也可以實現hook的功能。

建立一個

TestHookObject類

  <objc/objc.h> <objc/runtime.h>+ (         Method sendEvent = class_getInstanceMethod([UIWindow = class_getInstanceMethod([self          IMP sendEventImp =         IMP sendEventMySelfImp = - ()sendEventHooked:(UIEvent *)         NSLog(         [self performSelector:@selector(sendEventOriginal:) withObject:

在Appdelegate裡面加入

- (IBAction)btnAction:(- (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *=    self.viewController = [[[ViewController alloc] initWithNibName:=    TestHookObject *hookSendEvent =*btn = [[UIButton alloc] initWithFrame:CGRectMake(, , , = CGPointMake(, =

試著跑起來看看吧。
