本文实例为大家分享了iOS实现相册多选图片上传的具体代码，供大家参考，具体内容如下

原理：获取手机里的全部照片，显示在自定义的视图里

//获取到相册的所有图片

- (void)addAllPhotos{

@WeakObj(self);

_assetsLibrary=[[ALAssetsLibrary alloc]init];

[_assetsLibrary enumerateGroupsWithTypes:ALAssetsGroupSavedPhotos usingBlock:^(ALAssetsGroup *group, BOOL *stop) {

@StrongObj(self);

if (group) {

[group enumerateAssetsUsingBlock:^(ALAsset *result, NSUInteger index, BOOL *stop) {

if (result) {

// 把相册储存到数组中，方便后面展示相册时使用

CGImageRef cgImage = [result thumbnail];

UIImage *image = [UIImage imageWithCGImage:cgImage];

NSData *imageData = UIImageJPEGRepresentation(image,0.5);

UIImage *newImage = [UIImage imageWithData:imageData];

UZGPhotoChooseModel *model=[[UZGPhotoChooseModel alloc]init];

model.image=newImage;

model.currentImageIsSelect=NO;//初始化默认未选中

model.showBackView=NO;//是否显示背景遮罩

model.row=index;

[self.cellInfoArray addObject:model];

[self.myCollectionView reloadData];

}

}];

}

} failureBlock:^(NSError *error) {

}];

}

//选中图片后刷新图片上面的选中数字

- (selectCellBolck)reloadCellSelectBlock:(NSIndexPath *)indexPath{

@WeakObj(self);

__block UZGPhotoChooseModel *model=self.cellInfoArray[indexPath.row];

selectCellBolck block=^(BOOL current_isSelect){

if (selfWeak.selectNum>self.max_selectNum) {

return;

}

if (current_isSelect) {

selfWeak.selectNum++;

}else{

selfWeak.selectNum--;

}

model.currentImageIsSelect=current_isSelect;

model.totalNum=selfWeak.selectNum;

[selfWeak.cellInfoArray replaceObjectAtIndex:indexPath.row withObject:model];

[selfWeak reloadCurrentNum];

[selfWeak.myCollectionView reloadData];

};

return block;

}
