iOS移动View点击事件

在做开发的时候发现移动中的view不能点击，在网上找了很久之后自己写了一个移动的view点击事件，希望对大家有帮助废话不多说，直接开始。

新建工程，先删除文件中的ViewController.h和ViewController.m文件，新建MoveViewController继承于UIViewController

将MoveViewController作为window的根视图控制器，代码如下

在AppDelegate.m文件导入头文件

#import "MoveViewController.h"
接着在

- (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary
*)launchOptions {}

函数中添加如下代码，并且在Info.plist文件中将Main storyboard file base name关键字段的Main删除

MoveViewController *moveViewVc = [[MoveViewController alloc]init];
UINavigationController *nav = [[UINavigationController alloc]initWithRootViewController:moveViewVc];
_window = [[UIWindow alloc] initWithFrame:[UIScreen mainScreen].bounds];
_window.rootViewController = nav;
[_window makeKeyAndVisible];

现在根视图控制变成MoveViewController，然后就可以在MoveViewController中进行操作了

在这之前我们需要先封装一个移动视图

新建文件继承于UIView

moveView.h文件代码如下：

//
// moveView.h
// ZQMoveViewClick
//
// Created by 赵前 on 16/6/1.
// Copyright © 2016年 赵前. All rights reserved.
//

#import <UIKit/UIKit.h>

@interface moveView : UIView

/**
移动视图的头部视图
*/
@property(nonatomic, strong)UIImageView *imageView;

/**
移动视图的文字
*/
@property(nonatomic, strong)UILabel *labelView;

@endmoveView.m文件代码：

//
// moveView.m
// ZQMoveViewClick
//
// Created by 赵前 on 16/6/1.
// Copyright © 2016年 赵前. All rights reserved.
//

#import "moveView.h"

@implementation moveView

- (instancetype)initWithFrame:(CGRect)frame
{
self = [super initWithFrame:frame];
if (self) {
self.backgroundColor = [UIColor grayColor];
[self AddSubViews];
}
return self;
}

#pragma mark *** Private Method ***
- (void)AddSubViews{
[self addSubview:self.imageView];
[self addSubview:self.labelView];
}

#pragma mark *** Lazy Loading ***
- (UIImageView *)imageView{
if (!_imageView) {
_imageView = [[UIImageView alloc]initWithFrame:CGRectMake(0, 0, self.bounds.size.width*0.6, self.bounds.size.height*0.6)];
_imageView.center = CGPointMake(self.bounds.size.width/2, 5 + _imageView.bounds.size.height/2);
_imageView.backgroundColor = [UIColor greenColor];
}
return _imageView;
}
- (UILabel *)labelView{
if (!_labelView) {
_labelView = [[UILabel alloc]initWithFrame:CGRectMake(0, 0,self.bounds.size.width*0.3, self.bounds.size.height*0.3)];
_labelView.center = CGPointMake(self.bounds.size.width/2, CGRectGetMaxY(_imageView.frame) + 5 + _labelView.bounds.size.height/2);
_labelView.text = @"test";
_labelView.backgroundColor = [UIColor orangeColor];
}
return _labelView;
}

@end


视图封装好了之后，就可以在MoveViewController操作了。

MoveViewController.h文件代码如下：

//
// MoveViewController.h
// ZQMoveViewClick
//
// Created by 赵前 on 16/6/1.
// Copyright © 2016年 赵前. All rights reserved.
//

#import <UIKit/UIKit.h>

@interface MoveViewController : UIViewController

/**
moveViewCount 创建的要移动的视图数量
*/
-(void)CreateMoveView;

@endMoveViewController.m代码如下

//
// MoveViewController.m
// ZQMoveViewClick
//
// Created by 赵前 on 16/6/1.
// Copyright © 2016年 赵前. All rights reserved.
//

#import "MoveViewController.h"
#import "moveView.h"
#define WIDTH [UIScreen mainScreen].bounds.size.width
#define HEIGHT [UIScreen mainScreen].bounds.size.height
#define Tag 100
@interface MoveViewController ()
{
NSTimer *_timer;/**< 设置气泡滚动开始时间*/
NSArray *_dataSource;
}

@end

@implementation MoveViewController
- (void)initializeDataSource{
_dataSource = @[@"1",@"2",@"3",@"4",@"5",@"6",@"7",@"8",@"9"];
}

-(void)CreateMoveView{
UITapGestureRecognizer *tap = [[UITapGestureRecognizer alloc]initWithTarget:self action:@selector(respondsToGesture:)];
_timer = [NSTimer scheduledTimerWithTimeInterval:20 target:self selector:@selector(respondsToTimer:) userInfo:nil repeats:YES];
int wid = WIDTH - 100;
int hei = HEIGHT - 124;
for (int i = 0; i < _dataSource.count; i++) {
CGFloat w = (arc4random() % wid + 0);
CGFloat h = (arc4random() % hei + 0);
moveView *bubble = [[moveView alloc]initWithFrame:CGRectMake(0, 0, 100, 80)];
bubble.userInteractionEnabled = YES;
bubble.center = CGPointMake(w, h);
bubble.tag = Tag + i;
bubble.layer.anchorPoint = CGPointMake(0, 0);
[bubble.layer setBackgroundColor:[UIColor clearColor].CGColor];
[self.view.layer addSublayer:bubble.layer];
[self.view addGestureRecognizer:tap];
[self.view addSubview:bubble];
}
}

#pragma mark *** Events ***
-(void)respondsToGesture:(UITapGestureRecognizer *)gesture {
// ShowInfoViewController *showInfoVc = [ShowInfoViewController new];
CGPoint touchPoint = [gesture locationInView:self.view];
for (int i = (int)_dataSource.count; i >=0; i--) {
UIView *temView = [self.view viewWithTag:(Tag + i)];
if ([temView.layer.presentationLayer hitTest:touchPoint]) {
temView.backgroundColor = [UIColor blueColor];
// [self.navigationController pushViewController:showInfoVc animated:YES];
return;
}
}
}

-(void)viewWillAppear:(BOOL)animated
{
[_timer setFireDate:[NSDate distantPast]];
}

-(void)viewDidDisappear:(BOOL)animated
{
[_timer setFireDate:[NSDate distantFuture]];
}

-(void)respondsToTimer:(NSTimer *)timer
{
int wid = WIDTH - 100;
int hei = HEIGHT - 124;
for (int i = 0; i < (int)_dataSource.count; i++) {
CGFloat w = (arc4random() % wid + 0);
CGFloat h = (arc4random() % hei + 0);
CGPoint poi = CGPointMake(w, h);
CAKeyframeAnimation *moveLayerAnimation = [CAKeyframeAnimation animationWithKeyPath:@"position"];
UIView *temView = [self.view viewWithTag:(Tag + i)];
moveLayerAnimation.values = @[[NSValue valueWithCGPoint:temView.center],
[NSValue valueWithCGPoint:poi]];
temView.center = poi;

moveLayerAnimation.duration = 20;
moveLayerAnimation.autoreverses = YES;
moveLayerAnimation.repeatCount = INFINITY;
moveLayerAnimation.timingFunction = [CAMediaTimingFunction functionWithName:kCAMediaTimingFunctionLinear];
[temView.layer addAnimation:moveLayerAnimation forKey:@"move"];
}
}

- (void)viewDidLoad {
[super viewDidLoad];
[self initializeDataSource];
self.view.backgroundColor = [UIColor whiteColor];
[self CreateMoveView];
}

@end

到此，就可以看见点击的效果了。

注意：这个代码只是简单的做出了效果，可以进行更好的封装实现，宏定义的Tag值是为了判断当前点击的是哪个View，以便进行取值，或者跳转到下一个界面的时候知道是点击的哪个view。

另外说明的一点是可以根据视图的层级点击（比如某个视图被一个视图遮住了，点击的时候只有在最上面的视图才会发生颜色的变化），如果点击之后要进一步操作，可以在下面函数中写
-(void)respondsToGesture:(UITapGestureRecognizer *)gesture {
// ShowInfoViewController *showInfoVc = [ShowInfoViewController new];
CGPoint touchPoint = [gesture locationInView:self.view];
for (int i = (int)_dataSource.count; i >=0; i--) {
UIView *temView = [self.view viewWithTag:(Tag + i)];
if ([temView.layer.presentationLayer hitTest:touchPoint]) {
temView.backgroundColor = [UIColor blueColor];
// [self.navigationController pushViewController:showInfoVc animated:YES];
//可以在这里写你想要做的事情
return;
}
}
}

效果图如下：
