UITableViewCell中的ClipsToBounds

Question

我一直在尝试在clipsToBounds到UITableViewCell的子类中设置true但不知何故再次成为false：

class CustomCell: UITableViewCell {

    override init(style: UITableViewCellStyle, reuseIdentifier: String?) {
        super.init(style: style, reuseIdentifier: reuseIdentifier)

        contentView.clipsToBounds = true
    }

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

    override func layoutSubviews() {
        print(contentView.clipsToBounds) // false
        super.layoutSubviews()
        print(contentView.clipsToBounds) // false
    }
}

是否有理由在false中再次成为contentView？我可以修理＆＃34;这可以通过在clipsToBounds中将true设置为layoutSubviews()，但感觉不对。

Answer 1

您可以尝试在layoutSubviews()中设置属性。 您还可以使用awakeFromNib()功能将clipsToBounds设置为true ..

Answer 2

我认为在<div className="dropdown"> <button className="btn btn-primary dropdown-toggle" type="button" data-toggle="dropdown"> <h6 style={{fontFamily: "'Open Sans', sans-serif", fontSize: "12px", fontVariant: "small-caps"}}> settings </h6> <span className="glyphicon glyphicon-cog" /> </button> <ul className="dropdown-menu" style={{textAlign: "center"}}> <li> <h5 style={{fontFamily: "'Open Sans', sans-serif", fontSize: "12px", fontVariant: "small-caps"}}> user: {this.state.data.username} </h5> </li> <li style={{display: "inline-block"}}> <button onClick={this.resetLayout} className="btn btn-default" style={{fontFamily: "'Open Sans', sans-serif", fontSize: "12px", fontVariant: "small-caps"}}> reset layout </button> </li> <li style={{display: "inline-block"}}> <button className="btn btn-default" style={{fontFamily: "'Open Sans', sans-serif", fontSize: "12px", fontVariant: "small-caps"}}> <a href="/logout" style={{color: "black"}}> logout</a></button> </li> </ul> </div> 上设置contentView之后，有时会更改clipsToBounds = true。请改为cell.contentView。
