使用CocoaPods可以很方便地引入AYRuntime。Podfile添加AYRuntime的依赖。
pod "AYRuntime"简介
AYRuntime中包含了一些关于Runtime的类库。
AYBlockInvocation
AYBlockInvocation可以很方便地动态调用block。用法与NSInvocation非常相似。
CGPoint (^block)(CGPoint) = ^CGPoint(CGPoint point) {
XCTAssert(CGPointEqualToPoint(CGPointMake(1.0, 1.0), point));
return CGPointMake(point.x + 1.0f, point.y + 1.0f);
};
AYBlockInvocation *invocation = [AYBlockInvocation invocationWithBlock:block];
CGPoint point = CGPointMake(1.0, 1.0);
//NSInvocation的参数从2开始，而AYBlockInvocation的参数从1开始
[invocation setArgument:&point atIndex:1];
[invocation invoke];
CGPoint result;
[invocation getReturnValue:&result];
XCTAssert(CGPointEqualToPoint(CGPointMake(2.0, 2.0), result));AYDeallocNotifier
AYDeallocNotifier利用runtime，在对象销毁时，可以去执行一些动作。
id ex = [self expectationWithDescription:@""];
dispatch_async(dispatch_get_global_queue(0, 0), ^{
AYTestSwizzleClass *object = [AYTestSwizzleClass new];
[object ay_notifyWhenDealloc:^{
[ex fulfill];
}];
});
[self waitForExpectationsWithTimeout:1 handler:nil];runtime.h
