## Problem
I got this error when trying to write a binary string into file.
`this._realReader.readAsArrayBuffer is not a function. (In
'this._realReader.readAsArrayBuffer(file)',
'this._realReader.readAsArrayBuffer' is undefined)
`
The error is thrown at FileReader.js, line 302.
`FileReader.prototype.readAsArrayBuffer = function (file) {
if (initRead(this, file)) {
return this._realReader.readAsArrayBuffer(file);
}
const totalSize = file.end - file.start;
readSuccessCallback.bind(this)('readAsArrayBuffer', null, file.start,
totalSize, function (r) {
const resultArray = (this._progress === 0 ? new
Uint8Array(totalSize) : new Uint8Array(this._result));
resultArray.set(new Uint8Array(r), this._progress);
this._result = resultArray.buffer;
}.bind(this));
};`
Here is how I call the FileWriter in my code:
`writeBlobToFile = (file: FileEntry, blob): angular.IPromise<void> => {
return this.$q((resolve, reject) => {
file.createWriter((fileWriter) => {
fileWriter.write(blob);
fileWriter.onwriteend = resolve;
fileWriter.onerror = reject;
}, reject);
});
};`
Currently I can only reproduce it on iOS, version 17.6 and version 18.0.
