Ios 如何在UIView转换WithView后运行代码？

我想在动画完成后运行代码块，但编译器显示以下错误：“不兼容的块指针类型将'void（^）（void）'发送到'void（^）（BOOL）'类型的参数”

这是我的代码，我不确定我做错了什么，请帮助，谢谢

[UIView transitionWithView:self.view duration:1.5
                   options:UIViewAnimationOptionTransitionFlipFromBottom //change to whatever animation you like
                animations:^ {
                    [self.view addSubview:myImageView1];
                    [self.view addSubview:myImageView2];
                }
                completion:^ {
                    NSLog(@"Animations completed.");
                    // do something...
                }];

您只是使用了错误的块类型：）它需要一个如下所示的块。键是

^（BOOL finished）{…}

[UIView transitionWithView:self.view duration:1.5
                   options:UIViewAnimationOptionTransitionFlipFromBottom //change to whatever animation you like
                animations:^ {
                    [self.view addSubview:myImageView1];
                    [self.view addSubview:myImageView2];
                }
                completion:^(BOOL finished){
                    if (finished) {
                        // Successful
                    }
                    NSLog(@"Animations completed.");
                    // do something...
                }];
