objective-c - 如何动态设置属性

Question

我正在使用以下代码为一系列 View 设置数组。 bunnyView1 到 bunnyView7 是在 Storyboard中创建的 UIImageView 的实例，但我想自动化该过程，以便我可以生成与代码的连接。我将如何在循环中设置值？

- (void)viewDidLoad
{   
NSMutableArray *hopAnimation = [[NSMutableArray alloc] initWithCapacity:20];
for (int i = 1; i <= 20; i++) {
    [hopAnimation addObject:[UIImage imageNamed:[NSString stringWithFormat:@"frame-%i.png", i]]];
}
self.bunnyView1.animationImages=hopAnimation;
self.bunnyView2.animationImages=hopAnimation;
self.bunnyView3.animationImages=hopAnimation;
self.bunnyView4.animationImages=hopAnimation;
self.bunnyView5.animationImages=hopAnimation;
self.bunnyView6.animationImages=hopAnimation;
self.bunnyView7.animationImages=hopAnimation;
self.bunnyView1.animationDuration=1;
self.bunnyView2.animationDuration=1;
self.bunnyView3.animationDuration=1;
self.bunnyView4.animationDuration=1;
self.bunnyView5.animationDuration=1;
self.bunnyView6.animationDuration=1;
self.bunnyView7.animationDuration=1;                             
[super viewDidLoad];

将您的变量添加到数组中。并迭代数组并设置值。例如，

NSArray *collection = [[NSArray    alloc]initWithObjects:@"object1",@"object2",@"object3",@"object4",nil];
