ELCImagePicker 学习总结(一)

• 1,  将文件夹ELCImagePicker拷贝到工程中
• 2，添加系统库AssetsLibrary.framework
• 3,  添加系统库MobileCoreServices
• 4，在头文件中加入引用#import "ELCImagePickerHeader.h"
• 5，在头文件中加入delegate的引用ELCImagePickerControllerDelegate
• 6,  替换之前的UIImagePickerController相关的初始化代码为

        ELCImagePickerController *elcPicker = [[ELCImagePickerController alloc] initImagePicker];
        elcPicker.maximumImagesCount = 100; //Set the maximum number of images to select to 100
        elcPicker.returnsOriginalImage = YES; //Only return the fullScreenImage, not the fullResolutionImage
        elcPicker.returnsImage = YES; //Return UIimage if YES. If NO, only return asset location information
        elcPicker.onOrder = YES; //For multiple image selection, display and return order of selected images
        elcPicker.mediaTypes = @[(NSString *)kUTTypeImage, (NSString *)kUTTypeMovie]; //Supports image and movie types
        elcPicker.imagePickerDelegate = self;
        [self.navigationController presentViewController:elcPicker animated:YES completion:nil];

• 7, 屏蔽之前的didFinishPickingMediaWithInfo 和 imagePickerControllerDidCancel而替换成

　　- (void)elcImagePickerControllerDidCancel:(ELCImagePickerController *)picker
　　　　{
    　　　　[self dismissViewControllerAnimated:YES completion:nil];
　　　　}

　　- (void)elcImagePickerController:(ELCImagePickerController *)picker didFinishPickingMediaWithInfo:(NSArray *)info{
    
    　　　　[picker dismissViewControllerAnimated:YES completion:nil];
　　　　}
