调节按钮的宽度我有一个表视图,并具有button.According到我的需要,我有时SET按钮的如何根据或长度限制:Textlength图像化背景
1.Title自定义单元格
或
2.Background而不标题
图像上runtime.The问题是我的按钮的大小具体宽度根据标题长度限制:Textlength的或根据背景图像size.I没有改变已尝试sizeToFi吨和cell.btnChat.sizeThatFits(backgroundimage.size)但它一点儿也不反映任何变化。
“按钮”条件是组标题和图像来设置背景图像。
func tableView(_ tableView: UITableView, cellForRowAt indexPath: IndexPath) -> UITableViewCell {
if blockChatForLogin{
if (chatRespones[indexPath.row].type == "text"){
//Adding rows in table
// let cell:ChatResponseController = self.tbChat.dequeueReusableCell(withIdentifier: "ChatResponseCell") as! ChatResponseController
let cell:CustLabelCell = self.tbChat.dequeueReusableCell(withIdentifier: "CustomLabelCell") as! CustLabelCell
cell.lblTextResponse.text = chatRespones[indexPath.row].value
cell.lblTextResponse.layer.masksToBounds=true
cell.lblTextResponse.layer.cornerRadius=5
return cell
}
else if (chatRespones[indexPath.row].type == "button"){
//Adding rows in table
let cell:CustButtonCell = self.tbChat.dequeueReusableCell(withIdentifier: "CustomButtonCell") as! CustButtonCell
cell.btnChat.setTitle(chatRespones[indexPath.row].value,for: .normal)
cell.btnChat.layer.masksToBounds=true
cell.btnChat.layer.cornerRadius=5
cell.btnChat.layer.borderWidth=2
cell.btnChat.layer.borderColor=UIColor(red:0.18, green:0.61, blue:0.49 ,alpha:1.0).cgColor
cell.delegete = self
return cell
}
else if (chatRespones[indexPath.row].type == "image"){
//Adding rows in table
// let cell:ChatButtonController = self.tbChat.dequeueReusableCell(withIdentifier: "ChatButtonCell") as! ChatButtonController
let cell:CustButtonCell = self.tbChat.dequeueReusableCell(withIdentifier: "CustomButtonCell") as! CustButtonCell
if let image: UIImage = UIImage(named:"\(chatRespones[indexPath.row].value.replacingOccurrences(of: ":", with: "")).jpg")
{
cell.btnChat.setImage(image, for: .normal)
cell.btnChat.setTitle("",for: .normal)
cell.btnChat.backgroundColor = UIColor.clear
}
else{
cell.btnChat.backgroundColor = UIColor.clear
cell.btnChat.setTitleColor(UIColor.red, for: .normal)
cell.btnChat.setTitle("Error: Image Missing with name \(chatRespones[indexPath.row].value)",for: .normal)
}
cell.btnChat.layer.masksToBounds=true
cell.btnChat.layer.cornerRadius=5
cell.btnChat.layer.borderWidth=2
cell.btnChat.layer.borderColor=UIColor(red:0.18, green:0.61, blue:0.49 ,alpha:1.0).cgColor
cell.delegete = self
return cell
}
}
default:
print("No case")
}
}
显示你的代码,其中u根据长度限制:Textlength –
设置宽度不给在故事板按钮的一个固定的宽度,它根据文本调整自我。 –
在标题的情况下,你应该先算甜心或文本在标签和的UIImageView的情况下获得的高度和图片的宽度,然后设置动态buttonview高度和宽度根据你文字和ImageView的。 –
