Swift NSBundle pathForResource()返回nil [英] Swift NSBundle pathForResource() returns nil
问题描述
我的项目中有图像(仅在iPhone上支持，而在iPad上不支持).图像在一个组下，而不在images.xcassets下.
I have images in my project (which is only supported on iPhones, no iPads). The images are under a group and not under images.xcassets.
我想在所有iPhone上使用相同的图像，但6 Plus的@ 3x除外，所以我的结构如下:
I want to use the same image for all iPhones, except the @3x for the 6 Plus, so I have a structure as follows:
Project
|_ Images_Group
|
|_ pic01@2x.png
|_ pic01@3x.png
我正在使用以下代码在我的应用中使用它:
I am using this code to use it in my app:
if let path = NSBundle.mainBundle().pathForResource("pic01", ofType: "png") {
image = UIImage(contentsOfFile: path)
}
但是path总是返回nil.我需要pic01.png吗?
But path always returns nil. Do I need to have pic01.png?
该图像位于项目> 构建阶段> 复制捆绑资源下.我在做什么错了?
The image is present under Project > Build Phases > Copy Bundle Resources. What am I doing wrong?
推荐答案
此处要使用的工具是UIImage(named:)，它将按照您的建议查找图像. pathForResource是通用函数，没有针对图像的特殊规则.它正在专门寻找pic01.png，它不存在.
The tool you want here is UIImage(named:), which will look up images the way you're suggesting. pathForResource is a generic function that doesn't have special rules for images. It's looking specifically for pic01.png, which does not exist.
