作用

InjectionIII可以讓你更改的UI效果實時的在模擬器上顯示，無需重新啟動應用程序，從而節省開發人員的時間

使用方法

1. 在 App Store 下載安裝 InjectionIII
2. 添加相應的代碼
   Xcode10之前：

- (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions {
    
#if DEBUG
    // iOS
    [[NSBundle bundleWithPath:@"/Applications/InjectionIII.app/Contents/Resources/iOSInjection.bundle"] load];
    // tvOS
    [[NSBundle bundleWithPath:@"/Applications/InjectionIII.app/Contents/Resources/tvOSInjection.bundle"] load];
    // macOS
    [[NSBundle bundleWithPath:@"http://Applications/InjectionIII.app/Contents/Resources/macOSInjection.bundle"] load];
#endif
    
    // Override point for customization after application launch.
    return YES;
}

Xcode10之后：

- (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions {
    
#if DEBUG
    // iOS
    [[NSBundle bundleWithPath:@"/Applications/InjectionIII.app/Contents/Resources/iOSInjection10.bundle"] load];
    // tvOS
    [[NSBundle bundleWithPath:@"/Applications/InjectionIII.app/Contents/Resources/tvOSInjection10.bundle"] load];
    // macOS
    [[NSBundle bundleWithPath:@"http://Applications/InjectionIII.app/Contents/Resources/macOSInjection10.bundle"] load];
#endif
    
    // Override point for customization after application launch.
    return YES;
}

3. 選擇項目文件夾
