主要实现用户选择好照片后，一张一张上传，显示上传进度并且上传完服务器后显示图片
// 相册选的图片
- (void)imagePickerController:(TZImagePickerController *)picker didFinishPickingPhotos:(NSArray<UIImage *> *)photos sourceAssets:(NSArray *)assets isSelectOriginalPhoto:(BOOL)isSelectOriginalPhoto{
[self.dataArr addObjectsFromArray:photos];
if (self.maxImageCount == 6) {
_currentCount = self.imaUrlArr.count;
NSLog(@"取得的范围是%ld******%ld",self.imaUrlArr.count,self.dataArr.count);
[self uploadImage:photos];
for (int i = 0; i<photos.count ; i++) {
UIImage * image = [UIImage imageNamed:@"上传中"];
[self.dataArr replaceObjectAtIndex:self.imaUrlArr.count+i withObject:image];
[self reloadData];
}
}else{
[self reloadData];
}
}
#pragma mark - 单个上传图片
-(void)uploadImage:(NSArray *)arr{
static NSInteger index;
UIImage * image = arr[index];
NSData * imaData = UIImageJPEGRepresentation(image, 0.5);
[self showHudInView:self.view hint:[NSString stringWithFormat:@"正在上传第%ld张",index+1]];
[DNNetworking postWithURLString:strWith(@"upload",version02) parameters:nil imageData:imaData fileName:@"uploadFile" progress:^(NSProgress *progress) {

if ([NSString isEmptyOfString:obj[@"image"]] == NO){
NSLog(@"最终i的值为%ld",index);
[self reloadItemCellWithItem:index AndOrginArr:arr];
[_imaUrlArr addObject:obj[@"image"]];
index++;
[self hideHud];
if (index+1>arr.count) {
index = 0;
}else{
[self uploadImage:arr];
}
NSString *text = [self.imaUrlArr componentsJoinedByString:@","];
NSLog(@"%@",text);
}else
ShowInfoWithStatus(obj[@"errorMessage"]);
} failure:^(NSError *error) {

}
#pragma mark - 单个加载完图片之后显示
-(void)reloadItemCellWithItem:(NSInteger)item AndOrginArr:(NSArray *)arr{
