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(0, 0, 100, 100)]; button.backgroundColor = [UIColor redColor]; [button addTarget:self action:@selector(buttonEvent:) forControlEvents:UIControlEventTouchUpInside]; [self.view addSubview:button]; // 执行动画 [UIView animateWithDuration:10.f delay:0 options:UIViewAnimationOptionCurveLinear | UIViewAnimationOptionAllowUserInteraction animations:^{ button.frame = CGRectMake(0, 468, 100, 100); } 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(0, 0, 100, 100)]; 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:10.f delay:0 options:UIViewAnimationOptionCurveLinear | UIViewAnimationOptionAllowUserInteraction animations:^{ tmpView.frame = CGRectMake(0, 468, 100, 100); } 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 - 50 && point.x < presentationPosition.x + 50 && point.y > presentationPosition.y - 50 && point.y < presentationPosition.y + 50) { [tmpView touchesBegan:touches withEvent:event]; }}@end
ChildView.h 与 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(@"获取点击事件");}@end
