ios - 如何在Objective-C中识别自定义类与框架类

Question

我正在通过Swizzling UIViewController方法viewDidAppear和viewDidAppear进行分析项目，代码片段如下，

- (void) swizzledViewDidAppear : (BOOL)animated {
    if ([UA isAppInitialized]) { // Check if Analytics Initialized
        if ([[self class] isSubclassOfClass:[UIViewController class]]) {
            [UA startPage:[NSString stringWithFormat:@"%@",  NSStringFromClass ([self class])]];
        }
    }
    [self swizzledViewDidAppear:animated];
}

- (void) swizzledViewDidDisappear : (BOOL)animated {
    if ([UA isAppInitialized]) { // Check if Analytics Initialized
        if ([[self class] isSubclassOfClass:[UIViewController class]]) {
            [UA endPage:[NSString stringWithFormat:@"%@", NSStringFromClass ([self class])]];
        }
    }
    [self swizzledViewDidDisappear:animated];
}

这是我只跟踪自定义ViewController的代码段，例如:MyViewController或FooViewController ... etc，而不是与框架相关的类，如UICompatibilityInputViewController，UIInputWindowController ... etc。

请让我知道如何实现此目标。我试图检查Subclass，但是仍然有一段时间记录了Framework类。

谢谢，

您可以获取 class 的NSBundle并检查该捆绑包是否属于您。

使用扩展的快速示例:

//code
extension NSObject {
    static var isOurClass: Bool {
        let appBundle = Bundle.main
        let clsBundle = Bundle(for: self.self);
        return clsBundle.bundlePath.hasPrefix(appBundle.bundlePath)
    }
}

//test
@UIApplicationMain
class AppDelegate: UIResponder, UIApplicationDelegate {
    func application(_ application: UIApplication, didFinishLaunchingWithOptions launchOptions: [UIApplication.LaunchOptionsKey: Any]?) -> Bool {

        print("appdelegate class ours? \(AppDelegate.isOurClass)")
        print("NSString class ours? \(NSString.isOurClass)")
        return true
    }
}

基本objc示例:

#import <Foundation/Foundation.h>

@interface T : NSObject
@end

@implementation T
@end

int main(int argc, char *argv[]) {
    @autoreleasepool {
        NSBundle *bundleOfApp = [NSBundle mainBundle];
        NSLog(@"%@", bundleOfApp.bundlePath);

        //ours
        T *t = [T new];
        NSBundle *bundleOfT = [NSBundle bundleForClass:t.class];
        NSLog(@"%@", bundleOfT.bundlePath);

        if([bundleOfT.bundlePath hasPrefix:bundleOfApp.bundlePath]) {
            NSLog(@"ours");
        }

        //theirs

        bundleOfT = [NSBundle bundleForClass:NSString.class];
        NSLog(@"%@", bundleOfT.bundlePath);

        if([bundleOfT.bundlePath hasPrefix:bundleOfApp.bundlePath]) {
        }
        else {
            NSLog(@"theirs");
        }

    }
}
