我一直在使用Apple的WWDC视频教程处理iMessage扩展,但遇到了一个奇怪的错误。我从一个空白的项目开始,这个项目很好。但是,我为MSStickerBrowserViewController
添加了一个文件。代码已构建,但在模拟器中打开扩展程序会使其崩溃。奇怪的是,我从来没有制作过浏览器的实例。为什么代码没有被执行崩溃?
这里出现错误:dyld:未加载库:@ rpath / libswiftSwiftOnoneSupport.dylib 参考自:/Users/alextyshka/Library/Developer/CoreSimulator/Devices/BF34F16D-3CEF-4C7D-8D9A-D3D4B463F293/data/Containers/Bundle/Application/75E2E14B-E76B-4EC7-9528-7CE38864B55D/BlankMessages.app/PlugIns/ MessagesExtension.appex / MessagesExtension 原因:找不到图像 这是触发错误的代码:
import UIKit
import Messages
class MyStickerBrowserViewController: MSStickerBrowserViewController {
var stickers = [MSSticker]()
func changeBrowserViewBackgroundColor(color: UIColor) {
stickerBrowserView.backgroundColor = color
}
func loadStickers() {
createSticker(asset: "forest", localizedDescription: "forest sticker")
}
func createSticker(asset: String, localizedDescription: String) {
guard let stickerPath = Bundle.main().pathForResource(asset, ofType: "png") else {
print("couldn't create the sticker path for", asset)
return
}
let stickerURL = URL(fileURLWithPath: stickerPath) //This is the line that seems to be causing the error.
let sticker: MSSticker
do {
try sticker = MSSticker(contentsOfFileURL: stickerURL, localizedDescription: localizedDescription)
stickers.append(sticker)
} catch {
print(error)
return
}
}
/*
override func numberOfStickers(in stickerBrowserView: MSStickerBrowserView) -> Int {
}
override func stickerBrowserView(_ stickerBrowserView: MSStickerBrowserView, stickerAt index: Int) -> MSSticker {
}*/
}
我注意到如果我从第16行取出一个URL,则不会抛出错误。
Here是我遵循的WWDC视频的链接。我已仔细检查以确保我完全按照视频
答案 0 :(得分:0)
我重新安装了Xcode并且工作正常。奇怪的。感谢大家的建议!
