ios - 如何在 Swift 3 中加载自定义包

Question

在 Objective-C 中我是这样做的:

NSString *path = [[NSBundle mainBundle] pathForResource:@"LUIImages" ofType:@"bundle"];
path = [[NSBundle bundleWithPath:path] pathForResource:_imageHash ofType:nil];

但我似乎无法在 swift 3 中找到等价物

let bundlePath: String = Bundle.main.path(forResource: "LiveUI", ofType: "bundle")!

但下一步是什么？或者有没有更好的方法来加载自定义包？

Answer 1

使用 Bundle(path:) 构造函数并避免强制解包:

if let bundlePath = Bundle.main.path(forResource: "LiveUI", ofType: "bundle"),
    let bundle = Bundle(path: bundlePath),
    let path = bundle.path(forResource: "...", ofType: nil) {
    print(path)
} else {
    print("not found")
}

另一种方法是使用包标识符加载包 (在包的 Info.plist 中定义):

let bundle = Bundle(identifier: "com.company.bundle.LiveUI")
