ios - iOS 中本地通知自定义图像图标的大小是多少

Question

通常，应用程序图标显示为推送通知图像图标(左侧)。但是，如果我想在推送通知中添加自定义图像，我必须遵循图像的固定大小吗？ 感谢您的光临。

Answer 1

它的大小与您通常为应用提供的启动图像相同。

• 3.5": 640*960
• 4": 640*1136

这是 Apple 提供的一些描述:

The string is a filename of an image file in the app bundle. This image is a launching image specified for a given notification; when the user taps the action button (for example, “View”) or moves the action slider, the image is used in place of the default launching image. If the value of this property is nil (the default), the system either uses the previous snapshot, uses the image identified by the UILaunchImageFile key in the app’s Info.plist file, or falls back to Default.png.
