如何使一个按钮做多个动作X code [英] How to Make A button do more than one action xcode

问题描述

确定，所以在我的X code项目，我有一个按钮，我需要做同样的方法两次，但不同的图像plz帮助

code：

 的UIImage * toImage = [UIImage的imageNamed：@CharacterBackwards.png];
[UIView的transitionWithView：self.view
                  持续时间：0.01F
                   选项​​：UIViewAnimationOptionTransitionNone
                动画：^ {
                    自＆GT; Guy.image = toImage;
                }完成：NULL];睡眠（0.4）;
 

解决方案

这是什么方法都是。创建需要的图像名称的方法：

   - （无效）transitionToImage：（* NSString的）imageName {
    *的UIImage = toImage [UIImage的imageNamed：@CharacterBackwards.png];
    [UIView的transitionWithView：self.view
                      持续时间：0.01F
                       选项​​：UIViewAnimationOptionTransitionNone
                    动画：^ {
                        自＆GT; Guy.image = toImage;
                    }完成：NULL];
}
 

现在有你的按钮处理程序调用此两次：

   - （IBAction为）buttonHandler {
    [个体经营transitionToImage：@CharacterBackwards.png];
    [自performSelector：@选择（transitionToImage :) withObject：@CharacterForwards.pngafterDelay：0.4];
}
 

Ok So In My Xcode project I Have A button That I need to do the same method twice but with A Different Image Plz Help

Code:

UIImage * toImage = [UIImage imageNamed:@"CharacterBackwards.png"];
[UIView transitionWithView:self.view
                  duration:0.01f
                   options:UIViewAnimationOptionTransitionNone
                animations:^{
                    self->Guy.image = toImage;
                } completion:NULL];

sleep(0.4);

解决方案

This is what methods are for. Create a method that takes an image name:

- (void)transitionToImage:(NSString *)imageName {
    UIImage * toImage = [UIImage imageNamed:@"CharacterBackwards.png"];
    [UIView transitionWithView:self.view
                      duration:0.01f
                       options:UIViewAnimationOptionTransitionNone
                    animations:^{
                        self->Guy.image = toImage;
                    } completion:NULL];
}

Now have your button handler call this twice:

- (IBAction)buttonHandler {
    [self transitionToImage:@"CharacterBackwards.png"];
    [self performSelector:@selector(transitionToImage:) withObject:@"CharacterForwards.png" afterDelay:0.4];
}
