推荐答案

在此方法中，计算图像的高度，每行中使用的文本并将高度返回为一个浮动值。

In this method, calculate the height of images, text being used in each row and return the height as a float value.

例如：

-(CGFloat)tableView:(UITableView *)tableView heightForRowAtIndexPath:(NSIndexPath *)indexPath {

float totalHeight = 0.0;

BOOL ImageToBeDisplayed = [[yourDataArray objectAtIndex:indexPath.row]objectForKey@"yourImageKey"];

if(ImageToBeDisplayed)

totalHeight = 100 or some value of your choice
}
else{
//Do nothing
}

If your row has string data as well.

int length = [[[yourDataArray objectAtIndex:indexPath.row]objectForKey@"yourTextKey"] length];
if(length<40)
totalHeight + = 50;
else if (length<80 && length>40)
totalHeight + = 100;
and so on

and


return totalHeight;

}
