在view中实现UIViewController的跳转 By H.L

view中是不能进行UIViewController的push，pop等操作的，若进行跳转操作，一般是用代理，block,通知等实现，那如何实现在ViewController的subView中实现跳转操作呢，其实只要获取该view所在的ViewController即可。

获取view所在UIViewController

UIView+UIViewController.h

#import <UIKit/UIKit.h>

@interface UIView (UIViewController)

- (UIViewController *)viewController;

@end

UIView+UIViewController.m

#import "UIView+UIViewController.h"

@implementation UIView (UIViewController)

- (UIViewController *)viewController {

    //通过响应者链，获得view所在的视图控制器

    UIResponder *next = self.nextResponder;

    do {

        //判断响应者对象是否是视图控制器类型

        if ([next isKindOfClass:[UIViewController class]]) {

            return (UIViewController *)next;

        }

        next = next.nextResponder;

    }while(next != nil);

    return nil;

}

@end

- (UIViewController *)viewController {

    // Traverse responder chain. Return first found view controller, which will be the view's view controller.

    UIResponder *responder = self;

    while ((responder = [responder nextResponder]))

        if ([responder isKindOfClass: [UIViewController class]])

            return (UIViewController *)responder;

    return nil;

}

- (UIViewController*)viewController {

    for (UIView* next = [self superview]; next; next = next.superview) {

        UIResponder* nextResponder = [next nextResponder];

        if ([nextResponder isKindOfClass:[UIViewController class]]) {

            return (UIViewController*)nextResponder;

        }

    }

    return nil;

}

其它 iOS 获取当前正在显示的ViewController　

使用：

在subview中导入 #import "UIView+UIViewController.h"

-(void)viewDidSelect

{

    WebViewController *vc = [[WebViewController alloc] init];

    vc.webUrl =@"http://www.baidu.com";

    //如果VC 是添加在Nav 上的 用

    [self.viewController.navigationController pushViewController:ViewController animated:YES];

    //else 如果没有添加用

    [self presentModalViewController: ViewController animated:YES];

}
