如何动态设置属性

Question

我使用以下代码为一系列视图设置数组。 bunnyView1到bunnyView7是在故事板中创建的UIImageView的实例，但我想自动化这个过程，所以我可以用代码生成连接。如何在循环内设置值？

- (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];

}

Answer 1

在数组中添加变量。并迭代数组并设置值。例如，

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

Answer 2

你应该使用UIImageView的IBOutletCollection，每个bunnyView都应链接到它。宣言如下：

@property (nonatomic,retain) IBOutletCollection(UIImageView) NSArray * bunnyViews;
