照片选择器是APP开发中经常使用的功能.比如对商品的评价,某些报告提交等都会用到.在这里下载demo github地址 喜欢的可以给个星,谢谢!
你只要继承我demo的HWPublishBaseController就可以了.在下面有说明.我在demo设置的是最多上传9张照片,你可以自己根据需求修改,在工程中搜索
#define kMaxImageCount 9
这是我在项目中的使用,如图:
不废话,直接上代码.其中用了第三方的东西.我demo中的EvaluateViewController页是写功能的主要看这个页面就可以.它如上面所说就是继承的HWPublishBaseController.demo中的代码说明的很详细可以参照此样式自定义页面.先说一说Base页面.
这是Base页面,你可以新建一个页面继承它,然后自定义页面样式.其中你可以根据需求是要大图的数据信息还是缩放的小图信息.这是小图的://方形压缩图image 数组 @property(nonatomic,strong) NSMutableArray * imageArray;这是大图的- (NSArray*)getBigImageArray;上传图片就要根据需求了,网上有很多.
首先是.h文件

@end
这是.m文件 在新建页面调用 [self initPickerView];这个方法是 初始化collectionView 然后根据需求调用updatePickerViewFrameY这个方法这个是修改collectionView的位置即照片的显示位置.
