iOS软件开发实现类似微信上传图片选择

首先导入第三方库 ZMWImagePicker 

//然后在头文件中导入   #import "DNImagePickerController.h"

//方法可以在点击事件中调用

-(void)imgPicker
{
    DNImagePickerController * imagePicker =[[DNImagePickerController alloc]init];

    imagePicker.imagePickerDelegate =self;
    [self presentViewController:imagePicker animated:YES completion:nil];
   
}
//选择图片时调用的方法
-(void)dnImagePickerController:(DNImagePickerController *)imagePicker sendImages:(NSArray *)imageAssets isFullImage:(BOOL)fullImage imageArray:(NSArray *)imageArray
{
   


}
-(void)dnImagePickerControllerDidCancel:(DNImagePickerController *)imagePicker
{
    //返回时候调用的方法
    [imagePicker dismissViewControllerAnimated:YES completion:nil];

}

效果图:
