With the widespread use of mobile devices, more and more websites now provide H5 pages for mobile phones. For uniapp, one of the preferred frameworks for mobile development, H5 pages have also become an indispensable part. However, in H5 pages, sometimes there is a problem that iOS devices cannot upload images, or even preview images normally, which causes trouble to some developers. Next, this article will share some methods to solve the problem of uploading pictures on iOS in uniapp.
- Adjust image format
From the actual usage, the problem of uploading images on iOS devices is usually caused by the image format. When uploading images on the mobile terminal, in order to speed up the upload, some mobile phones will automatically save the images in .webp format, but iOS devices do not support this format. So we can solve this problem by setting the image saving format. In uniapp, you can set the image format in the following ways:
// 修改默认配置 export default { // 设置图片格式为jpeg #ifdef H5 ico: { type: 'image/jpeg', }, #endif }
- Use third-party component library
If you set it according to the above method, but the ios device still cannot upload Pictures, then you can consider using the third-party component library in uniapp to solve the problem. Currently, in uniapp, there are already some mature component libraries available for us to use, such as the upload plug-in uni-uploader. This plug-in can easily implement the image upload function by encapsulating some underlying APIs, and also supports cross-platform use. For the problem that ios devices cannot upload images, using the uni-uploader plug-in may help.
- Adjust browser parameters
For the problem that ios devices cannot preview images correctly, we can also make adjustments in some ways. One of the common methods is to set browser parameters, as shown below:
<meta>
With the above code, we can set the browser parameters to the device width and turn off the user zoom function to achieve better browsing Effect.
In short, to solve the problem that iOS devices cannot upload pictures in uniapp, we need to find methods from many aspects, because the cause of this problem is relatively complicated. I hope the above method can help everyone.
