performSelector延时调用

本文主要是介绍performSelector延时调用，希望对大家解决编程问题提供一定的参考价值，需要的开发者们随着小编来一起学习吧！

- (void)performSelector:(SEL)aSelector withObject:(id)anArgument afterDelay:(NSTimeInterval)delay;

performSelector单线程调用，当函数执行完成后调用aSelector方法，afterDelay参数为延时多少秒

-(IBAction)confirm:(id)sender{

    [self startLoading];

    NSMutableDictionary *dic = [NSMutableDictionary new];

    [dic setValue:_account_no forKey:ACCOUNT_NO];

    [dic setValue:[_passwdField.text MD5Sum] forKey:NEW_PASSWORD];

    AFHTTPRequestOperationManager *manager = [sswAFHttpShared sharedInstance];

    [manager POST:NET_MODIFY_PWD parameters:dic \

         success:^(AFHTTPRequestOperation *operation, id responseObject){

         NSDictionary *jsonDic = [operation.responseData toNSDictionary];

         [self stopLoading];

         if (![self IsRequestSuccess:jsonDic]){

             return ;

         }

        [LeafNotification  showInController:self withText:@"请求成功!" type:LeafNotificationTypeSuccess];

        [self performSelector:@selector(back) withObject:nil afterDelay:3.0];

     } \

         failure:^(AFHTTPRequestOperation *operation, NSError *error){

         NSLog(@"error code:%ld %@", (long)[error code], operation.responseString);

     }];

}

-(void)back{

    [self.navigationController popToRootViewControllerAnimated:NO];

}

多线程使用

- (void)performSelectorInBackground:(SEL)aSelector withObject:(id)arg

- (void)performSelectorOnMainThread:(SEL)aSelector withObject:(id)arg waitUntilDone:(BOOL)wait

这篇关于performSelector延时调用的文章就介绍到这儿，希望我们推荐的文章对编程师们有所帮助！
