最近做了一款清理類的 APP，說(shuō)實(shí)話，iOS 清理真沒(méi)什么可清理的，只能清理下相似照片，重復(fù)聯(lián)系人，日歷事件等
照片、視頻管理類
相似照片統(tǒng)計(jì)
我這里獲取了相冊(cè)的所有信息，并將相似照片，相似視頻，照片大于10M 和 視頻大于 20M 的大文件也整理了處理，可以直接調(diào)用，在屬性上直接獲取，記得刷新 UI 的時(shí)候要在主線程進(jìn)行操作，否則會(huì)崩潰
調(diào)用方法如下
- (ClearPhotoManager *)clearPhotoManager
{
if (!_clearPhotoManager)
{
_clearPhotoManager = [ClearPhotoManager shareManager];
}
return _clearPhotoManager;
}
-(void)loadPhotoData
{
// 加載照片數(shù)據(jù)源
CleanSelf(self);
[CleanOneLoading showWithMessage:CleanLanguage(@"Loading...",@"加載中...")];
[self.clearPhotoManager getAllBigAsset:^(BOOL success) {
// 這里有很多屬性，自己打印看看，這里列舉了兩個(gè)
CleanNsLog(@"%@",weakself.clearPhotoManager.similarInfo);
CleanNsLog(@"%@",weakself.clearPhotoManager.screenshotsInfo);
dispatch_async(dispatch_get_main_queue(), ^{
[weakself pushHomeVc];
[CleanOneLoading disMiss];
});
}];
}

2.修改對(duì)比的方法，減少圖片縮小后的大小，這里是最有效的，這樣會(huì)大大減小內(nèi)存，我減小到了 32 *32，不過(guò)量大肯定也會(huì)崩潰，我測(cè)試在同時(shí)對(duì)比 1500 張照片，210 個(gè)視頻下是不會(huì)崩潰的
// 是否相似

IplImage *iplimage1 = [self convertToIplImage:[self OriginImage:image1 scaleToSize:CGSizeMake(32, 32)]];
IplImage *iplimage2 = [self convertToIplImage:[self OriginImage:image2 scaleToSize:CGSizeMake(32, 32)]];
