#import <UIKit/UIKit.h>

typedef void(^resignFirstResponderBlock)(BOOL hided);

@interface UITextField (hideKeyBoard)
//延时注销第一响应者
-(BOOL)resignFirstResponder:(resignFirstResponderBlock)block;
@end

/**************************************************************************/

#import "UITextField+hideKeyBoard.h"

@implementation UITextField (hideKeyBoard)

/**

-(BOOL)resignFirstResponder:(resignFirstResponderBlock)block{
    dispatch_async(dispatch_get_global_queue(0, 0), ^{

        double delayInSeconds = 0.1;
        dispatch_time_t popTime = dispatch_time(DISPATCH_TIME_NOW, delayInSeconds * NSEC_PER_SEC);
        dispatch_after(popTime, dispatch_get_main_queue(), ^{
            [self resignFirstResponder];

            block(YES);
        });
        
    });
    return YES;
}

@end

使用：

   [textField resignFirstResponder:^(BOOL hided) {

                UIStoryboard *storyboard = [UIStoryboard storyboardWithName:@"LoginViewController" bundle:nil];
                LoginViewController * loginViewC = [storyboard instantiateViewControllerWithIdentifier:@"LoginViewController"];
                loginViewC.isAutomaticLogin = YES;
                [self.navigationController pushViewController:loginViewC animated:YES];

            }];
