Objective-C UIViewImage animation(Objective-C UIViewImage 动画)

问题描述

现在我可以使用下面的代码制作一个简单的动画.但是，以下解决方案需要我预定义图像名称.我该怎么做 NSArray.push("image1.png");例如?然后将动态数组赋值为animationImages?

Right now I'm able to do a simple animation using the code below. However, the below solution needs me to predefine the image names. How can I do something like NSArray.push("image1.png"); for example? Then assign the dynamic array as the animationImages?

谢谢你，三通

UIImageView* animationView = [[UIImageView alloc] initWithFrame:self.view.frame];

animationView.animationImages = [NSArray arrayWithObjects:  
[UIImage imageNamed:@"transition 1.png"],
[UIImage imageNamed:@"transition 2.png"],
[UIImage imageNamed:@"transition 3.png"],
[UIImage imageNamed:@"transition 4.png"],
[UIImage imageNamed:@"transition 5.png"], nil];

推荐答案

你可以使用NSMutableArray，并使用 addObject: 向其中添加对象.例如:

You can use NSMutableArray, and add objects to it using addObject:. For example:

NSMutableArray *a = [NSMutableArray array];
[a addObject:[UIImage imageNamed:@"transition 1.png"]];
[a addObject:[UIImage imageNamed:@"transition 1.png"]];

animationView.animationImages = a;
