按钮在执行frame动画的时候怎么响应触发事件？

代码中效果（请注意，我并没有点击到按钮，而是点击到按钮的终点frame值处）：

对应的代码：

//
// ViewController.m
// TapButton
//
// Created by YouXianMing on 14/12/7.
// Copyright (c) 2014年 YouXianMing. All rights reserved.
//#import "ViewController.h"@interface ViewController ()@end@implementation ViewController- (void)viewDidLoad {
[super viewDidLoad]; // 初始化按钮
UIButton *button = [[UIButton alloc] initWithFrame:CGRectMake(, , , )];
button.backgroundColor = [UIColor redColor];
[button addTarget:self
action:@selector(buttonEvent:)
forControlEvents:UIControlEventTouchUpInside];
[self.view addSubview:button]; // 执行动画
[UIView animateWithDuration:.f
delay:
options:UIViewAnimationOptionCurveLinear | UIViewAnimationOptionAllowUserInteraction
animations:^{
button.frame = CGRectMake(, , , );
} completion:^(BOOL finished) { }];
}/**
* 按钮事件
*
* @param button 按钮事件
*/
- (void)buttonEvent:(UIButton *)button {
NSLog(@"YouXianMing");
}@end

修改过后的效果：

源码：

//
// ViewController.m
// TapButton
//
// Created by YouXianMing on 14/12/7.
// Copyright (c) 2014年 YouXianMing. All rights reserved.
//#import "ViewController.h"
#import "ChildView.h"@interface ViewController (){ ChildView *tmpView;}@end@implementation ViewController- (void)viewDidLoad {
[super viewDidLoad]; // 初始化按钮
tmpView = [[ChildView alloc] initWithFrame:CGRectMake(, , , )];
tmpView.backgroundColor = [UIColor redColor];
tmpView.userInteractionEnabled = NO; // 让self.view获取点击事件（穿透自身）
[self.view addSubview:tmpView]; // 执行动画
[UIView animateWithDuration:.f
delay:
options:UIViewAnimationOptionCurveLinear | UIViewAnimationOptionAllowUserInteraction
animations:^{
tmpView.frame = CGRectMake(, , , );
} completion:^(BOOL finished) { }];
}- (void)touchesBegan:(NSSet *)touches withEvent:(UIEvent *)event {
// 获取点击点
CGPoint point = [[touches anyObject] locationInView:self.view]; // 获取tmpView的layer当前的位置
CGPoint presentationPosition = [[tmpView.layer presentationLayer] position]; // 判断位置，让tmpView接受点击事件
if (point.x > presentationPosition.x - && point.x < presentationPosition.x + &&
point.y > presentationPosition.y - && point.y < presentationPosition.y + ) {
[tmpView touchesBegan:touches withEvent:event];
}
}@end

ChildView.h 与 ChildView.m

//
// ChildView.m
// TapButton
//
// Created by YouXianMing on 14/12/7.
// Copyright (c) 2014年 YouXianMing. All rights reserved.
//#import "ChildView.h"@implementation ChildView- (void)touchesBegan:(NSSet *)touches withEvent:(UIEvent *)event {
NSLog(@"获取点击事件");
}@end

关键性的两步：
