用一個分類,具體:
.h

#import 

@interface UIView (CurrentController)

/** 獲取當前View的控制器對象 */
-(UIViewController *)getCurrentViewController;

@end

.m

#import "UIView+CurrentController.h"

@implementation UIView (CurrentController)

/** 獲取當前View的控制器對象 */
-(UIViewController *)getCurrentViewController{
    UIResponder *next = [self nextResponder];
    do {
        if ([next isKindOfClass:[UIViewController class]]) {
            return (UIViewController *)next;
        }
        next = [next nextResponder];
    } while (next != nil); 
    return nil;
}

@end
