按鈕在執行frame動畫的時候怎么響應觸發事件？

代碼中效果（請注意，我并沒有點擊到按鈕，而是點擊到按鈕的終點frame值處）：

對應的代碼：

// // 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];// 初始化按鈕UIButton *button = [[UIButton alloc] initWithFrame:CGRectMake(0, 0, 100, 100)];button.backgroundColor = [UIColor redColor];[button addTarget:selfaction:@selector(buttonEvent:)forControlEvents:UIControlEventTouchUpInside];[self.view addSubview:button];// 執行動畫[UIView animateWithDuration:10.fdelay:0options:UIViewAnimationOptionCurveLinear | UIViewAnimationOptionAllowUserInteractionanimations:^{button.frame = CGRectMake(0, 468, 100, 100);} completion:^(BOOL finished) {}]; }/*** 按鈕事件** @param button 按鈕事件*/ - (void)buttonEvent:(UIButton *)button {NSLog(@"YouXianMing"); }@end

修改過后的效果：

源碼：

// // 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];// 初始化按鈕tmpView = [[ChildView alloc] initWithFrame:CGRectMake(0, 0, 100, 100)];tmpView.backgroundColor = [UIColor redColor];tmpView.userInteractionEnabled = NO; // 讓self.view獲取點擊事件（穿透自身） [self.view addSubview:tmpView];// 執行動畫[UIView animateWithDuration:10.fdelay:0options:UIViewAnimationOptionCurveLinear | UIViewAnimationOptionAllowUserInteractionanimations:^{tmpView.frame = CGRectMake(0, 468, 100, 100);} completion:^(BOOL finished) {}]; }- (void)touchesBegan:(NSSet *)touches withEvent:(UIEvent *)event {// 獲取點擊點CGPoint point = [[touches anyObject] locationInView:self.view];// 獲取tmpView的layer當前的位置CGPoint presentationPosition = [[tmpView.layer presentationLayer] position];// 判斷位置，讓tmpView接受點擊事件if (point.x > presentationPosition.x - 50 && point.x < presentationPosition.x + 50 &&point.y > presentationPosition.y - 50 && point.y < presentationPosition.y + 50) {[tmpView touchesBegan:touches withEvent:event];} }@end

ChildView.h 與?ChildView.m

// // ChildView.h // TapButton // // Created by YouXianMing on 14/12/7. // Copyright (c) 2014年 YouXianMing. All rights reserved. // #import <UIKit/UIKit.h>@interface ChildView : UIView@end // // 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(@"獲取點擊事件"); }@end

關鍵性的兩步：
