我在iOS 8上调整uitablecell高度时遇到一些问题。
- (CGFloat) tableView:(UITableView *)tableView heightForRowAtIndexPath:(NSIndexPath *)indexPath {
if (!SYSTEM_VERSION_GREATER_THAN_OR_EQUAL_TO(@"8.0")){
// Calculate a height based on a cell
if(!self.customCell) {
self.customCell = [self.availableTableView dequeueReusableCellWithIdentifier:CellIdentifier];
}
NSLog(@"initial height: %f", self.customCell.contentView.frame.size.height);
//retrieve current object for use with this indexpath.row
AvailableRouteObject *availableRouteObj = [[AvailableRouteObject alloc] init];
availableRouteObj = [availableRoutesArray objectAtIndex:indexPath.row];
dateFormatter = [[NSDateFormatter alloc] init]; // here we create NSDateFormatter object for change the Format of date..
[dateFormatter setDateFormat:@"yyyy-MM-dd"]; //// here set format of date which is in your output date (means above str with format)
NSDate *date = [dateFormatter dateFromString: availableRouteObj.Date]; // here you can fetch date from string with define format
dateFormatter2 = [[NSDateFormatter alloc] init];
[dateFormatter2 setDateFormat:@"MMM dd"];// here set format which you want...
NSString *convertedDate = [dateFormatter2 stringFromDate:date]; //here convert date in NSString
NSString *dateAppend = [NSString stringWithFormat:@"%@\n%@", convertedDate, availableRouteObj.Day];
self.customCell.date.text = dateAppend;
self.customCell.areaDetails.text = availableRouteObj.Area;
self.customCell.collectionDetails.text = availableRouteObj.BakeryDisplay;
self.customCell.deliveryDetails.text = availableRouteObj.HomeDisplay;
//layout the cell
//[self.customCell setNeedsUpdateConstraints];
[self.customCell setNeedsLayout];
//[self.customCell updateConstraintsIfNeeded];
[self.customCell layoutIfNeeded];
//get the hieght for the cell
CGFloat height = [self.customCell.contentView systemLayoutSizeFittingSize:UILayoutFittingCompressedSize].height;
NSLog(@"height: %f", height);
//return height + 1.0f;
return height + 1.0f;
}else{
NSLog(@"YES! I AM iOS 8");
availableTableView.estimatedRowHeight = 340;
return UITableViewAutomaticDimension;
}
}

请告诉我如何解决问题，以便iOS 8中的uitablecell与iOS 7中的uitablecell相同。
感谢。我已经尝试解决这个问题好几天但我无法这样做。
