嗨，我是iPad新手。所以我使用Web服务在tableview中显示数据。那么如何更改我尝试的每个单元格的行高，但是它显示了更高的高度？ 我使用三个数组在tableview中显示数据所以如果我通过Web服务向数组提供更多数据。那么如何更改表格视图的每一行。任何人都可以帮助我吗？
- (NSInteger)tableView:(UITableView *)tableView numberOfRowsInSection:(NSInteger)section{
return [arrOutline1 count] + [arrOutline2 count];
}
- (CGFloat)tableView:(UITableView *)tableView heightForRowAtIndexPath:(NSIndexPath *)indexPath
{
if ((indexPath.row)%2==0) {
return 100;
}
else {
//strData3 =[[NSMutableString alloc]init];
NSLog(@" the data is %@",[arrOutline3 objectAtIndex:countRow]);
//strData3 = [NSMutableString stringWithFormat:@"%@",[arrOutline3 objectAtIndex:countRow]];
int myLength = [[NSMutableString stringWithFormat:@"%@",[arrOutline3 objectAtIndex:countRow]] length];
NSLog(@" the length of dat is :%d",myLength);
int LengthCell;
int LengthCell = myLength /3;
CGFloat heightCell3 ;
int l = LengthCell * 19;
heightCell3 =(CGFloat )l;
NSLog(@" the heigh of cell is :%f",heightCell3 );
countRow = countRow + 1;
return heightCell3;
}

答案 0 :(得分：2)
您可以尝试委托方法：
-(void)tableView:(UITableView *)tableView willDisplayCell:(UITableViewCell *)cell
forRowAtIndexPath:(NSIndexPath *)indexPath
并根据索引路径指定单元格参数的高度。
答案 1 :(得分：2)
您可以在此委托中更改UITableViewCell高度 -
- (CGFloat)tableView:(UITableView *)tableView
heightForRowAtIndexPath:(NSIndexPath *)indexPath
{ }
为了使其正常工作，您可以动态地计算出内容高度，或者具有一些预定义的高度100,150,200等。＆amp;根据您的数据的某些截止，使用其中一个高度...将降低复杂性。
否则你可能想找到长度
答案 2 :(得分：1)
- (CGFloat) tableView: (UITableView *) tableView heightForRowAtIndexPath: (NSIndexPath *) indexPath
{
CGSize labelSize = CGSizeMake(200.0, 20.0);
NSString *strTemp = [arrServices objectAtIndex:indexPath.row];
if ([strTemp length] > 0)
labelSize = [strTemp sizeWithFont: [UIFont boldSystemFontOfSize: 14.0] constrainedToSize: CGSizeMake(labelSize.width, 1000) lineBreakMode: UILineBreakModeWordWrap];
return (labelSize.height + 10);
}
这是我在我的项目中使用的，它运作得非常好。根据您的要求更改值。
