EasyImagePicker 介绍
EasyImagePicker是一款能够一行代码搞定图片的选择控制器UIImagepicker，抛开代理什么的都不用管。
代码如下：
GoodPicker *picker = [GoodPicker imagePickerDidFinishPickImage:^(NSDictionary *dict, UIImage *image) {
//图片选择成功后该block调用。参数说明：dict所选择的图片的信息，image选择到的图片
self.myImageView.image = image;
} didCancelPickImage:^(UIImagePickerController *picker) {
//点击取消的时候该block调用
[picker dismissViewControllerAnimated:YES completion:nil];
}];
