How can i set UITableView cell height programmatically in Swift
提问by Rahmat Hidayat
How to set view height programmatically i have try this code
如何以编程方式设置视图高度我已经尝试过这段代码
cell.viewMain.frame = CGRectMake(cell.viewMain.frame.origin.x, cell.viewMain.frame.origin.y, cell.viewMain.frame.size.width, 65.0)
But that is not working.
但这行不通。
UPDATE :
更新 ：
func tableView(tableView: UITableView, cellForRowAtIndexPath indexPath: NSIndexPath) -> UITableViewCell {
let cell = tableView.dequeueReusableCellWithIdentifier("updateCell", forIndexPath: indexPath) as! UpdateCell
if self.data[indexPath.row] == "b" {
tbUpdate.rowHeight = 85
cell.viewMain.frame = CGRectMake(cell.viewMain.frame.origin.x, cell.viewMain.frame.origin.y, cell.viewMain.frame.size.width, 65.0)
}else{
tbUpdate.rowHeight = 220
cell.viewMain.frame = CGRectMake(cell.viewMain.frame.origin.x, cell.viewMain.frame.origin.y, cell.viewMain.frame.size.width, 200.0)
}
return cell
}
回答by Jan Franz Palngipang
first, rowHeight changes the height of all rows in your table. if you want specific height for specific rows, implement tableView:heightForRowAtIndexPath:method. remove tbUpdate.rowHeight in your code first.
首先，rowHeight 更改表中所有行的高度。如果您想要特定行的特定高度，请实现tableView:heightForRowAtIndexPath:方法。首先删除代码中的 tbUpdate.rowHeight。

TableView cells have their height set by the table view.
TableView 单元格的高度由表格视图设置。
You need to implement UITableViewDelegate tableView:heightForRowAtIndexPath:.
您需要实施UITableViewDelegate tableView:heightForRowAtIndexPath:.

You can try using autolayout to create a height constrait and then connect the constraint to an outlet. Then set the constant for that constraint,
您可以尝试使用自动布局来创建高度约束，然后将约束连接到出口。然后为该约束设置常量，
var y: Float
if x==0{ //some condition
y = 10
}else if x==1{ //some condition
y = 20
}
cell.viewMainHeightConstraint.constant = y
cell.view.layoutIfNeeded()
Put this in your cellForRowAtIndexPath
把它放在你的 cellForRowAtIndexPath 中
Edit : I misinterpreted the question as asking for another view within the cellView, if so the delegate method heightForRowAtIndexPath is indeed correct as stated in the above answer.
编辑：我将问题误解为在 cellView 中要求另一个视图，如果是这样，则委托方法 heightForRowAtIndexPath 确实如上述答案中所述。
An example:
一个例子：
func tableView(tableView: UITableView, heightForRowAtIndexPath indexPath: NSIndexPath) -> CGFloat
{
if x == 0{
return 100.0 //Choose your custom row height
} else {
return 50
}
}

override func tableView(_ tableView: UITableView, heightForRowAt indexPath: IndexPath) -> CGFloat {
var cellHeight:CGFloat = CGFloat()
if indexPath.row % 2 == 0 {
cellHeight = 20
}
else if indexPath.row % 2 != 0 {
cellHeight = 50
}
return cellHeight
}
回答by Vishal Vaghasiya
func tableView(_ tableView: UITableView, heightForRowAt indexPath: IndexPath) -> CGFloat {
var height:CGFloat = CGFloat()
if indexPath.row == 0 {
height = 80
}
else if indexPath.row == 1 {
height = self.view.frame.size.height - 44 - 64 // 44 is a tab bar height and 64 is navigationbar height.
print(height)
}
return height
}
