选择相册照片或者拍照

  __weak typeof(self) weakSelf = self;
    TOActionSheet *actionSheet = [[TOActionSheet alloc] init];
    actionSheet.contentstyle = TOActionSheetContentStyleDefault;
    actionSheet.style = TOActionSheetStylekinema;
    [actionSheet addButtonWithTitle:@"拍照" icon:nil  tappedBlock:^{
        __strong typeof(weakSelf) sself = weakSelf;
        [sself makePhoto];
    }];
    [actionSheet addButtonWithTitle:@"从手机相册选择" icon:nil  tappedBlock:^{
        __strong typeof(weakSelf) sself = weakSelf;
        [sself choosePicture];
    }];
    [actionSheet showFromView:self.certificateImgeView inView:weakSelf.view];

拍照

 if([UIImagePickerController isSourceTypeAvailable:UIImagePickerControllerSourceTypeCamera]){
        UIImagePickerController *picker = [[UIImagePickerController alloc] init];
        picker.delegate = self;
        picker.allowsEditing = YES;
        picker.sourceType = UIImagePickerControllerSourceTypeCamera;
        [self presentViewController:picker animated:YES completion:nil];
    }

  if([UIImagePickerController isSourceTypeAvailable:UIImagePickerControllerSourceTypePhotoLibrary]){
        UIImagePickerController *picker = [[UIImagePickerController alloc] init];
        picker.delegate = self;
        picker.allowsEditing = YES;
        picker.sourceType = UIImagePickerControllerSourceTypePhotoLibrary;
        [self presentViewController:picker animated:YES completion:nil];

//获取到图片
- (void)imagePickerController:(UIImagePickerController *)picker didFinishPickingMediaWithInfo:(NSDictionary *)info
{
    [self dismissViewControllerAnimated:YES completion:^{
        UIImage *image = [info objectForKey:UIImagePickerControllerOriginalImage];
        [self compressOriginalImage:image toMaxDataSizeKBytes:200];
        NSUserDefaults *defaults = [NSUserDefaults standardUserDefaults];
        if (image) {
            [defaults setObject:[self compressOriginalImage:image toMaxDataSizeKBytes:200]  forKey:@"certificateImg"];
        }
        [self.tableView reloadData];
    }];
}

//取消获取照片
