请教一下，如何方便地改变title的文字

[pangpingfei]

如Pull to refresh，没有找到现成的方法，只能自定义吗？

[eggswift]

建议根据业务，自定义刷新组件。 如果只需要改文案的话，可以考虑集成自ESRefreshHeaderAnimator，然后在init方法中重新赋值

@eggswift 我试了一下：

class RefreshHeaderAnimator: ESRefreshHeaderAnimator {
    convenience override init(frame: CGRect) {
        self.init(frame: frame)
        pullToRefreshDescription = "..."
        releaseToRefreshDescription = "..."
        loadingDescription = ""
    }
}

当执行到self.init时停顿了下，就挂了。不知道什么原因。求教

@eggswift 搞定了！

class RefreshHeaderAnimator: ESRefreshHeaderAnimator {

    override var pullToRefreshDescription: String {
        get { return "下拉刷新" }
        set {  }
    }

    override var releaseToRefreshDescription: String {
        get { return "松手立即刷新" }
        set {  }
    }

    override var loadingDescription: String {
        get { return "正在刷新..." }
        set {  }
    }

}

你犯了一个错误

public class RefreshHeaderAnimator: ESRefreshHeaderAnimator {

    override init(frame: CGRect) {
        super.init(frame: frame) //这里要用super
        pullToRefreshDescription = "..."
        releaseToRefreshDescription = "..."
        loadingDescription = ""
    }

    public required init(coder aDecoder: NSCoder) {
        fatalError("init(coder:) has not been implemented")
    }
}
