iOS facebook PoP 初体验

说到pop，我学到了很多。第一次使用了，cocopods工具，因为不熟悉操作，昨天弄了好久，终于给掌握了。从安装到运行。为了给更多的人能够学到pop，我今天写一个完全版的从cocopods运用到pop动画简单介绍。

1.cocopods的安装。打开终端输入这个命令:  gem sources --remove https://rubygems.org/  等有反应后再输入：  gem sources -a http://ruby.taobao.org/  最好输入  gem sources -l

查看是否有

有了这个我们就可以安装cocopods了。然后在终端中输入   sudo gem install cocoapods  下载，这时候你可以喝杯茶，等它自动下载完成。下载完成后你就可以使用了。我们先创建一个工程。然后重新打开终端。先用命令行进入所在文件夹我是放在桌面上（cd ~/Desktop/ 文件名）再终端中输入 touch podfile    这时你会看见有个红箭头指向的文件。然后现在你利用mac自带的文本编辑器打开它在里面输入：

platform :ios, ‘7.0‘
pod ‘pop‘, ‘~> 1.0‘

这样就ok了。然后，我们再终端中输入：pod install  它会下载，下载完成后问价夹里面会多处如下几个文件：

你现在要打开的是xcworkspace，运行，不必去打开原来的那个xocde了。运行后，检查下有没有错误，没有恭喜你，可以接下去做事情了。

我们先来看下我的代码：

#import "ViewController.h"
#import <pop/POP.h>
@interface ViewController ()
{
    UIButton *_btn;
    UIImageView *_imageView;
    
    BOOL _isOpened;
}
@end

@implementation ViewController

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

    
    [self createBtn];
    
    
}

-(void)createBtn
{
    
    
   _btn = [UIButton buttonWithType:UIButtonTypeSystem];
    _btn.frame = CGRectMake(100, 100, 100, 100);
    [_btn setTitle:@"wq" forState:UIControlStateNormal];
    [_btn setTitleColor:[UIColor whiteColor] forState:UIControlStateNormal];
    _btn.backgroundColor = [UIColor redColor];
    [_btn addTarget:self action:@selector(playAction) forControlEvents:UIControlEventTouchUpInside];
    [self.view addSubview:_btn];
    
    
    
    _imageView= [[UIImageView alloc]init];
    _imageView.backgroundColor = [UIColor blueColor];
    _imageView.frame = CGRectMake(100, 200, 200, 200);
    _imageView.userInteractionEnabled = YES;
    //拖动
    UIPanGestureRecognizer *pan = [[UIPanGestureRecognizer alloc]initWithTarget:self action:@selector(handlePan:)];
    [_imageView addGestureRecognizer:pan];
    [self.view addSubview:_imageView];
    
    
    
    
    
    //点击手势
    UITapGestureRecognizer *gestureForSpring = [[UITapGestureRecognizer alloc]init];
    [gestureForSpring addTarget:self action:@selector(changsSize:)];
    [self.view addGestureRecognizer:gestureForSpring];
 
    self.navigationItem.rightBarButtonItem = [[UIBarButtonItem alloc]initWithTitle:@"+" style:UIBarButtonItemStyleDone target:self action:@selector(showPop)];

    
    
}

//出现的时候
-(void)showPop
{
    
    
    
    if (_isOpened) {
        [self hidePop];
        return;
    }

    positionAnimation.toValue =[NSValue valueWithCGRect:CGRectMake(300, 0, 0, 0)];
    //key一样就会用后面的动画覆盖之前的
    [_imageView pop_addAnimation:positionAnimation forKey:@"frameAnimation"];
    
    _isOpened = NO;
