推荐答案

其他答案按预期工作。

创建新文件，选择 Objective-C类

• 类： MyApplication


• 子类： UIApplication

• Class: MyApplication
• Subclass of: UIApplication

将此代码粘贴到中。 m 文件：

- (BOOL)openURL:(NSURL *)url {
    if  ([self handleOpenURL:url])
        return YES;
    else
        return [super openURL:url];
}
- (BOOL)handleOpenURL:(NSURL*)url {
    NSLog(@"my url handler");
    return YES;
}

接下来打开你的 main.m 并更改第三个参数

next open your main.m and change the third parameter

return UIApplicationMain(argc, argv, nil, NSStringFromClass([SampleAppDelegate class]));

到 UIApplication -subclass name

to your UIApplication-subclass name

return UIApplicationMain(argc, argv, @"MyApplication", NSStringFromClass([SampleAppDelegate class]));
