【问题描述】:
我在UICell 旁边有两个UILabel,其中包含动态文本,因此我需要根据内容调整其框架的大小,为此我使用[string sizeWithFont] 方法来计算标签视图框架在@ 内的高度987654324@heightForRowAtIndexPath根据标签高度设置单元格的高度。现在问题是当我滚动表格时,如果我删除[label sizeToFit] 方法,单元格内的标签开始缩小,它不会缩小,但我的标签会重叠,看起来很乱。我哪里错了,请指导我..
这是我的cellRowAtIndexPath 方法代码
- (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath
{
NSLog(@"cell");
BOOL ente = FALSE;
static NSString *CellIdentifier = @"CustomCell";
CustomCell *cell = (CustomCell *) [tableView dequeueReusableCellWithIdentifier:CellIdentifier];
if (cell == nil) {
NSArray *topLevelObjects = [[NSBundle mainBundle] loadNibNamed:@"CustomCell" owner:nil options:nil];
for (id currentObject in topLevelObjects){
if ([currentObject isKindOfClass:[UITableViewCell class]]){
cell = (CustomCell *) currentObject;
ente = TRUE;
break;
}
}
}
/*
[cell.title sizeToFit];
[cell.dataTime sizeToFit];
CGSize size1 = [[mainEventArray objectAtIndex:[indexPath row]] sizeWithFont:[UIFont systemFontOfSize:13.0f] constrainedToSize:CGSizeMake(275, MAXFLOAT) lineBreakMode:UILineBreakModeWordWrap];
cell.title.frame = CGRectMake(50, 6, size1.width, size1.height);
CGSize size2 = [[mainEventTimeArray objectAtIndex:[indexPath row]] sizeWithFont:[UIFont systemFontOfSize:11.0f] constrainedToSize:CGSizeMake(275, MAXFLOAT) lineBreakMode:UILineBreakModeWordWrap];
cell.dataTime.frame = CGRectMake(50, 24, size2.width, size2.height);
*/
cell.title.text = [mainEventArray objectAtIndex:[indexPath row]];
cell.dataTime.text = [mainEventTimeArray objectAtIndex:[indexPath row]];
//if (ente) {
// NSLog(@"helllloo");
[cell.title sizeToFit];
[cell.dataTime sizeToFit];
//}
return cell;
}
对于heightForRowAtIndexPath 方法
- (CGFloat)tableView:(UITableView *)tableView heightForRowAtIndexPath:(NSIndexPath *)indexPath
{
static NSString *CellIdentifier = @"CustomCell";
CustomCell *cell = (CustomCell *) [tableView dequeueReusableCellWithIdentifier:CellIdentifier];
{
if (cell == nil) {
NSArray *topLevelObjects = [[NSBundle mainBundle] loadNibNamed:@"CustomCell" owner:nil options:nil];
for (id currentObject in topLevelObjects){
if ([currentObject isKindOfClass:[UITableViewCell class]]){
cell = (CustomCell *) currentObject;
break;
}
}
}
}
CGSize size1 = [[mainEventArray objectAtIndex:[indexPath row]] sizeWithFont:[UIFont systemFontOfSize:13.0f] constrainedToSize:CGSizeMake(230, MAXFLOAT) lineBreakMode:UILineBreakModeWordWrap];
cell.title.frame = CGRectMake(0, 0, size1.width, size1.height);
CGSize size2 = [[mainEventTimeArray objectAtIndex:[indexPath row]] sizeWithFont:[UIFont systemFontOfSize:11.0f] constrainedToSize:CGSizeMake(230, MAXFLOAT) lineBreakMode:UILineBreakModeWordWrap];
cell.dataTime.frame = CGRectMake(0, 0, size2.width, size2.height);
//NSLog(@"%f", size1.height + size2.height + 20);
return size1.height + size2.height + 20;
//NSString *str = [heights_ objectAtIndex:[indexPath row]];
// return [str floatValue] ;
}
