iOS实现相册多选图片上传功能
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=[[ALAssetsLibraryalloc]init];
[_assetsLibraryenumerateGroupsWithTypes:ALAssetsGroupSavedPhotosusingBlock:^(ALAssetsGroup*group,BOOL*stop){
@StrongObj(self);
if(group){
[groupenumerateAssetsUsingBlock:^(ALAsset*result,NSUIntegerindex,BOOL*stop){
if(result){
//把相册储存到数组中，方便后面展示相册时使用
CGImageRefcgImage=[resultthumbnail];
UIImage*image=[UIImageimageWithCGImage:cgImage];
NSData*imageData=UIImageJPEGRepresentation(image,0.5);
UIImage*newImage=[UIImageimageWithData:imageData];
UZGPhotoChooseModel*model=[[UZGPhotoChooseModelalloc]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.cellInfoArrayaddObject:model];
[self.myCollectionViewreloadData];
}
}];
}
}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);
__blockUZGPhotoChooseModel*model=self.cellInfoArray[indexPath.row];
selectCellBolckblock=^(BOOLcurrent_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.cellInfoArrayreplaceObjectAtIndex:indexPath.rowwithObject:model];
[selfWeakreloadCurrentNum];
[selfWeak.myCollectionViewreloadData];
};
returnblock;
}
