iOS開發類似上傳頭像小操作Demo
代碼：

圖片選取器前面的tablvew裡的東西

- (void)tableView:(UITableView *)tableView didSelectRowAtIndexPath:(NSIndexPath *)indexPath{    // 圖片選取器    UIImagePickerController *imgPC = [[UIImagePickerController alloc] init];    //設定代理    imgPC.delegate = self;    //允許編輯圖片    imgPC.allowsEditing = YES;    if (indexPath.row == 0) {        NSLog(@"從手機相簿選擇圖片");        //圖片庫        imgPC.sourceType = UIImagePickerControllerSourceTypePhotoLibrary;        if ([UIImagePickerController isSourceTypeAvailable:UIImagePickerControllerSourceTypePhotoLibrary]){            //顯示控制器            [self presentViewController:imgPC animated:YES completion:nil];        }else{            [SVProgressHUD showInfoWithStatus:@"請允許程式開啟相簿"];        }    }else if(indexPath.row == 1){       NSLog(@"拍照");        //拍照        imgPC.sourceType = UIImagePickerControllerSourceTypeCamera;        //顯示控制器        if ([UIImagePickerController isSourceTypeAvailable:UIImagePickerControllerSourceTypeCamera]){            //顯示控制器            [self presentViewController:imgPC animated:YES completion:nil];        }else{            [SVProgressHUD showInfoWithStatus:@"請允許程式運行拍照功能"];        }    }}

選擇好圖片後在相簿或者照相後的圖片右下角選擇圖片按鈕點擊

#pragma - mark 圖片選擇成功後的代理- (void)imagePickerController:(UIImagePickerController *)picker didFinishPickingMediaWithInfo:(NSDictionary *)info{    NSLog(@"info== %@",info);    //擷取修改後的圖片    UIImage *editedImg = info[UIImagePickerControllerEditedImage];    self.iconView.image = editedImg;    [self dismissViewControllerAnimated:YES completion:nil];}
