首先要请求七牛云的token
- (void)loadSenvenToken{
NSString *url = [NSString stringWithFormat:@"%@%@",URL_Base,URL_CommentsToken];
[NetworkManager requestGETWithURLStr:url paramDic:nil Api_key:self.apikey finish:^(id responseObject) {
NSLog(@"token请求成功%@",responseObject);
self.token = [responseObject objectForKey:@"token"];
} enError:^(NSError *error) {
NSLog(@"失败%@",error);
}];
}
选择要上传的图片，完成后对图片进行处理，七牛云每次只能上传一张，所以要把对上传图片的处理写在添加图片方法完成后，这样每张图片都得到处理
- (void)loadAddPhotesViewWith:(UIView *)view{
// 只选择照片 addPhotoView 添加图片的view
HX_AddPhotoView *addPhotoView = [[HX_AddPhotoView alloc] initWithMaxPhotoNum:3 WithSelectType:SelectPhoto];
addPhotoView.backgroundColor = [UIColor whiteColor];
// 每行最大个数 不设置默认为4
addPhotoView.lineNum = 3;
// collectionView 距离顶部的距离 底部与顶部一样 不设置,默认为0
addPhotoView.margin_Top = 5;
// 距离左边的距离 右边与左边一样 不设置,默认为0
addPhotoView.margin_Left = 10;
// 每个item间隔的距离 如果最小不能小于5 不设置,默认为5
addPhotoView.lineSpacing = 5;
addPhotoView.delegate = self;
addPhotoView.frame = CGRectMake(0,65, size_width - 20, 0);
[view addSubview:addPhotoView];
/** 当前选择的个数 */
// addPhotoView.selectNum;
[addPhotoView setSelectPhotos:^(NSArray *photos, NSArray *videoFileNames, BOOL iforiginal) {
NSLog(@"photo - %@",photos);
[photos enumerateObjectsUsingBlock:^(id asset, NSUInteger idx, BOOL * _Nonnull stop) {
PHAsset *twoAsset = (PHAsset *)asset;
CGFloat scale = [UIScreen mainScreen].scale;
// 根据输入的大小来控制返回的图片质

[[HX_AssetManager sharedManager] accessToImageAccordingToTheAsset:twoAsset size:size resizeMode:PHImageRequestOptionsResizeModeFast completion:^(UIImage *image, NSDictionary *info) {
self.img = image;
[self.photoList addObject:image];
NSLog(@"*********%@",image);// 选择几张走几次 3
[self getImagePath:image];
[self uploadImageToQNFilePath:[self getImagePath:self.img]];
}];
}];
}];
}
//照片获取本地路径转换
- (NSString *)getImagePath:(UIImage *)Image {
NSString *filePath = nil;
NSData *data = nil;
if (UIImagePNGRepresentation(Image) == nil) {
data = UIImageJPEGRepresentation(Image, 1.0);
} else {

}
//图片保存的路径
//这里将图片放在沙盒的documents文件夹中

//文件管理器

//把刚刚图片转换的data对象拷贝至沙盒中

//得到选择后沙盒中图片的完整路径
filePath = [[NSString alloc] initWithFormat:@"%@%@", DocumentsPath, ImagePath];
return filePath;
}
- (void)uploadImageToQNFilePath:(NSString *)filePath {
// self.token = @"你的token";
QNUploadManager *upManager = [[QNUploadManager alloc] init];

} option:uploadOption];
}
保存事件
self.photoList 要上传的图片数组
self.keyArr 没上传一张图片成功后返回的key的数组
// 选择的图片都上传成功了
if (self.photoList.count == self.keyArr.count ) {
// 图片上传后，保存
[self loadProduct];// 提交给服务器 做的是评论
}else{
