只是想知道,我该怎么用这个?
我只需要在图像名称之后设置 @ 2x 吗? 还是把它放在特定的文件夹里? 或者其他的吗?
谢谢你的忠告
仅以文件名命名 。 例如, 请命名您的喷洒 320x480 默认值. png, 然后命名您的 640x960 < a href="/ cdn- cgi/ l/ email- protect" 类 = "...cf_ email_ email_" 数据- cefmail="dabebbbcbbafb6ae9ae8a2f4aab4bd > [email proted]
您需要做的就是在您的工程中添加第二个图像, 其名称与原始图像相同, 恰好是原图像的两倍, 在扩展名之前的文件名结尾处的@ 2x 。
示例:
一些图片. png 是 20x40 像素
< a href=" "/cdn-cgi/l/email-protect" 类="__cf_email_" 数据—efemail="bekdd1d3db93ced7ddcacbccdbdbfe8cc690ced0d9" >[email protected]
使用 imageNamed: 方法时,只需通过原名,如 [UIImaage 图像Named: @ " some- picture.png"]
使用界面构建器时也使用同样的方式 。
它会自动在运行时选择右键 。
苹果实际上详细描述了预期的文件名,详情见:“更新您的图像资源文件”部分,该iOS绘图指南。
具体地说,在文件中查找这些行:
Standard: <ImageName><device_modifier>.<filename_extension>
High resolution: <ImageName>@2x<device_modifier>.<filename_extension>
