我正在IONIC 4中创建pdf。以下代码在Web和android上有效,但在IOS上无效。在IOS中,它会发出alert(“创建文件时出错:” + err);

  .catch(err => {
              this.runloading = 'hide';
              alert("Error creating file: " + err);
              throw err;
            });
if (this.platform.is("cordova")) {
        this.pdfObj.getBuffer(buffer => {
          var blob = new Blob([buffer], { type: "application/pdf" });
          this.file
            .writeFile(this.file.externalRootDirectory, "pro.pdf", blob, {
              replace: true
            })
            .then(fileEntry => {
              this.fileOpener
                .open(
                  this.file.externalRootDirectory + "pro.pdf",
                  "application/pdf"
                )
                .catch(err => alert("Please install pdf viewer"));
              this.runloading = 'hide';

            })
            .catch(err => {
              this.runloading = 'hide';
              alert("Error creating file: " + err);
              throw err;
            });
        });
      } else {
        pdfmake.createPdf(docDefinition).open();
        // this.pdfObj.download();
        this.runloading = 'hide';
      }

请参阅下面的此消息。有一个错误会阻止统一体验iOS上的本地文件下载。

两个选择: 1.将pdf上载到服务器,然后重新下载。 2.等待iOS13
