iOS-获取当前View所在的控制器

用一个分类,具体:
.h

#import <UIKit/UIKit.h>

@interface UIView (CurrentController)

/** 获取当前View的控制器对象 */
-(UIViewController *)getCurrentViewController;

@end

.m

#import "UIView+CurrentController.h"

@implementation UIView (CurrentController)

/** 获取当前View的控制器对象 */
-(UIViewController *)getCurrentViewController{
    UIResponder *next = [self nextResponder];
    do {
if ([next isKindOfClass:[UIViewController class]]) {
return (UIViewController *)next;
        }
        next = [next nextResponder];
    } while (next != nil); 
return nil;
}

@end
