iOS app icon with transparent background showing black background on device
提问by Fengson
I have added an icon to my app. It has rounded edges and no background. The problem is that when I run an app on my device (iPhone 5) the icon has a black background behind the edges as if it wasn't transparent. Any solutions?
我在我的应用程序中添加了一个图标。它有圆形边缘，没有背景。问题是当我在我的设备（iPhone 5）上运行一个应用程序时，图标的边缘后面有一个黑色背景，好像它不透明。任何解决方案？

From the apple developer website after a quick search:
快速搜索后从苹果开发者网站：
Avoid transparency. An app icon should be opaque. If the icon's boundaries are smaller than the recommended sizes—or you use transparency to create “see-through” areas—the resulting icon can appear to float on a black background, which tends to look especially unattractive on the beautiful wallpapers that users choose.
避免透明。应用程序图标应该是不透明的。如果图标的边界小于推荐的尺寸——或者你使用透明度来创建“透明”区域——生成的图标可能看起来漂浮在黑色背景上，这在用户选择的漂亮壁纸上看起来特别没有吸引力。

On IOS use just square icons, if you use rounder icons you will have black margin black background.
在 IOS 上只使用方形图标，如果您使用圆形图标，您将获得黑色边缘黑色背景。
