Objective-C的UIViewImage动画 [英] Objective-C UIViewImage animation

问题描述

现在我能够做到用低于code一个简单的动画。
但是，下面的解决方案，需要我predefine图像名称。
我怎么可以这样做NSArray.push（image1.png）;例如？然后，动态数组作为animationImages分配？

感谢您，
T恤

 的UIImageView * animationView = [[UIImageView的页头] initWithFrame：方法self.view.frame];animationView.animationImages = [NSArray的arrayWithObjects：
[UIImage的imageNamed：@过渡1.png]，
[UIImage的imageNamed：@过渡2.png]，
[UIImage的imageNamed：@过渡3.png]，
[UIImage的imageNamed：@过渡4.png]，
[UIImage的imageNamed：@过渡5.png]，无]
 

解决方案

您可以使用<一个href=\"http://developer.apple.com/mac/library/DOCUMENTATION/Cocoa/Reference/Foundation/Classes/NSMutableArray%5FClass/Reference/Reference.html\"相对=nofollow> 的NSMutableArray ，并使用 ADDOBJECT对象添加到它：。例如：

 的NSMutableArray * A = [NSMutableArray的阵列]
[A ADDOBJECT：[UIImage的imageNamed：@过渡1.png]];
[A ADDOBJECT：[UIImage的imageNamed：@过渡1.png]];animationView.animationImages =一个;
 

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?

Thank you, Tee

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];

解决方案

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;
