目标C：拖放多个图像

Question

我正在尝试对我拥有的不同图像应用拖放功能但我的代码不起作用，它对我视图中的图像没有影响。

这是我的代码：

    if([touch view]==imageOne){
        CGPoint location=[touch locationInView:self.view];
        imageOne.center=location;
        return;
    }

    if([touch view]==imageTwo){
        CGPoint location=[touch locationInView:self.view];
        imageTwo.center=location;
        return;

    }
    if([touch view]==imageThree){
        CGPoint location=[touch locationInView:self.view];
        imeageThree.center=location;
        return;

    }
    if([touch view]==imageFour){
        CGPoint location=[touch locationInView:self.view];
        imageFour.center=location;
        return;

    }
    if([touch view]==imageFive){
        CGPoint location=[touch locationInView:self.view];
        imageFive.center=location;
        return;

    }

将UIImageView的userInteractionEnabled属性设置为YES。默认情况下，它将是NO。有关详细信息，请参阅Apple documentation
