Clearing cache not working

Hi,

I’m trying to clear the cache under ionic 4 in iOS.

My code looks like this:

const filesBefore = await this.file.listDir(this.file.cacheDirectory, 'image-loader-cache');
console.log('Files before:', filesBefore);
await this.imageLoader.clearCache();
const filesAfter = await this.file.listDir(this.file.cacheDirectory, 'image-loader-cache');
console.log('Files after:', filesAfter);

In the console it looks like this:

Files before: [Array] (306)
Files after: [Array] (306)

Thank you @Bart1909 To solve the problem of delete the old image, I did a method to remove the cached file. It works! But while I doesn’t restart the app, the image not change (dont know why). So, to change it instantly I ended up doing the same approach as you, adding a query parameter to load again.

If anyone wants, to remove the cached file:

async removeCacheFile(myImagePath: string): Promise<void> {
    try {
        const cachePath: string = await this.imageLoader.getImagePath(myImagePath);
        const filename: string = cachePath.substr(cachePath.lastIndexOf('/') + 1);
        const exists: boolean = await this.file.checkFile(this.file.cacheDirectory + "image-loader-cache/", filename);
        if (exists) {
            await this.file.removeFile(this.file.cacheDirectory + "image-loader-cache/", filename);
        }
    } catch (error) {
        console.error(error);
    }
}
