當文本比平常長時,heightForRowAtIndexPath從不顯示多行。heightForRowAtIndexPath不顯示多行
這裏是我的代碼:
#define FONT_SIZE 14.0f
#define CELL_CONTENT_WIDTH 320.0f
#define CELL_CONTENT_MARGIN 10.0f
- (CGFloat)tableView:(UITableView *)tableView heightForRowAtIndexPath:(NSIndexPath *)indexPath
{
CGFloat result = 44.0f;
CGFloat width = 0;
CGFloat tableViewWidth;
CGRect bounds = [UIScreen mainScreen].bounds;
if (UIInterfaceOrientationIsPortrait(self.interfaceOrientation))
tableViewWidth = bounds.size.width;
else
tableViewWidth = bounds.size.height;
width = tableViewWidth - 110; // fudge factor, 115 isn't quite right
NSUInteger index = [indexPath row];
id doc = [[self displayedObjects] objectAtIndex:index];
NSString *title = [doc title];
if (title)
{
// The notes can be of any height
// This needs to work for both portrait and landscape orientations.
// Calls to the table view to get the current cell and the rect for the
// current row are recursive and call back this method.
CGSize textSize = { width, 20000.0f }; // width and height of text area
CGSize size = [title sizeWithFont:[UIFont systemFontOfSize:14.0f] constrainedToSize:textSize lineBreakMode:UILineBreakModeWordWrap];
size.height += 29.0f; // top and bottom margin
result = MAX(size.height, 44.0f); // at least one row
}
return result;
}
任何幫助將非常感激。 謝謝!
嗨弗洛裏安,問題是,我不知道應該多少行文本使用(是可變的),所以設置numberOfLines = 3我想這不適用於每個單元格。 – baboso 2011-03-05 18:55:05
