iOS之路10-給xib設置約束注意

 

refreshView是Xib,,用UINib加載Xib

    let nib = UINib(nibName: "RefreshView", bundle: nil)
        
    return nib.instantiateWithOwner(nil, options: nil)[0] as! RefreshView

給xib設置約束的時候必定要重寫賦值size,,用當前的大小賦值便可,,若是不設置,,位置可能不對的

        refreshView.snp_makeConstraints { (make) -> Void in
          // make.centerX.equalTo(self.snp_centerX)
          // make.centerY.equalTo(self.snp_centerY)
            make.center.equalTo(self.snp_center)
            make.size.equalTo(refreshView.bounds.size)
        }
