DownloadButton 是可自定义的 App Store 风格的下载按钮。可自定义设计组件,用 IB 进行编辑。
使用示例:

#pragma mark - PKDownloadButtonDelegate  - (void)downloadButtonTapped:(PKDownloadButton *)downloadButton                   currentState:(PKDownloadButtonState)state {      switch (state) {          case kPKDownloadButtonState_StartDownload:              self.downloadButton.state = kPKDownloadButtonState_Pending;              [self.pendingSimulator startDownload];          break;          case kPKDownloadButtonState_Pending:              [self.pendingSimulator cancelDownload];              self.downloadButton.state = kPKDownloadButtonState_StartDownload;          break;              case kPKDownloadButtonState_Downloading:              [self.downloaderSimulator cancelDownload];              self.downloadButton.state = kPKDownloadButtonState_StartDownload;          break;          case kPKDownloadButtonState_Downloaded:              self.downloadButton.state = kPKDownloadButtonState_StartDownload;              self.imageView.hidden = YES;          break;          default:              NSAssert(NO, @"unsupported state");          break;      }  }  #pragma mark - DownloaderSimulatorDelegate  - (void)simulator:(PKDownloaderSimulator *)simulator didUpdateProgress:(double)progress {      if (simulator == self.pendingSimulator) {          if (progress == 1.) {              self.downloadButton.state = kPKDownloadButtonState_Downloading;              [self.downloaderSimulator startDownload];          }      }      else if (simulator == self.downloaderSimulator) {          self.downloadButton.stopDownloadButton.progress = progress;          if (progress == 1) {              self.downloadButton.state = kPKDownloadButtonState_Downloaded;              self.imageView.hidden = NO;          }      }  }
