变量IBOutlet名称？ [英] Variable IBOutlet name?

问题描述

是否可以使用可变的插座名称？
例如，您有10个标签（也许在公共汽车上有座位）。每个都有出口，seat1 seat2等。
是否可能有一个for循环
，它将@ seat连接到增量整数。这样我就可以访问seat1，seat2出口，而不必单独指定它。
这行不通，但使我想达到的目标更加清晰。

Is it possible to have a variable outlet name?. For example you have 10 labels (perhaps seats on bus). each has an outlet, seat1 seat2 etc. Is it possible to have a for loop that concatenates @"seat" to the increment integer. So that I can access seat1, seat2 outlet without having to specify it individually. This doesn’t work but makes it a bit clearer what I am trying to achieve.

int i;
for (i = 0; i < [seatarray count]; i++)
{
    [@"seat"  stringByAppendingString[ i stringValue]] = @"";
}

推荐答案

从iOS4开始，您可以使用 IBOutletCollection 允许将多个实例连接到代表一个对象数组的单个出口，例如IBOutletCollection仅可存储UILabel：

Starting iOS4 you can use IBOutletCollection which allows to connect multiple instances to a single outlet which represents an array of objects, e.g. IBOutletCollection which can store UILabels only:

@property (nonatomic, retain) IBOutletCollection(UILabel) NSArray *seats;
