Programatically add margin in UITableView cell?
提问by iosfreak
I am trying to add margin to a cell. I have tried many times with different methods but have failed. Please help!
我正在尝试为单元格添加边距。我用不同的方法尝试了很多次，但都失败了。请帮忙！
- (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath {
static NSString *CellIdentifier = @"Cell";
UITableViewCell *cell = [tableView dequeueReusableCellWithIdentifier:CellIdentifier];
if (cell == nil) {
cell = [[[UITableViewCell alloc] initWithFrame:CGRectZero reuseIdentifier:CellIdentifier] autorelease];
}
tableView.rowHeight = 60;
// InitWithStyle
cell = [[[UITableViewCell alloc] initWithStyle:UITableViewCellStyleSubtitle reuseIdentifier:CellIdentifier] autorelease];
// Get Selected Name
NSString *selectedCountry = [listOfItems objectAtIndex:indexPath.row];
// Set up the cell...
NSString *cellValue = [listOfItems objectAtIndex:indexPath.row];
cell.text = cellValue;
NSArray *resultstwoo = [database executeQuery:@"SELECT * FROM albums WHERE name=?", selectedCountry];
for (NSDictionary *rowtwoo in resultstwoo) {
NSString *connectionsText = [rowtwoo valueForKey:@"connections"];
cell.detailTextLabel.text = connectionsText;
}
// Get Selected ID
NSArray *resultsID = [database executeQuery:@"SELECT * FROM albums WHERE name=?", selectedCountry];
for (NSDictionary *rowID in resultsID) {
NSString *selectedIDtwo = [rowID valueForKey:@"id"];
// Get latest picture and Display
int imagesCount = 0;
NSArray *listOfItemsTwo = [database executeQuery:@"SELECT * FROM images WHERE album=? ORDER BY id DESC LIMIT 0,1", selectedIDtwo];
for (NSDictionary *rowone in listOfItemsTwo) {
imagesCount ++;
NSString *getDir = @"./../Documents/";
NSString *getID = [rowone valueForKey:@"id"];
NSString *getFile = @"_thumbnail.jpg";
NSString *theImagePath = [NSString stringWithFormat:@"%@%@%@",getDir, getID, getFile];
UIImage *theImage = [UIImage imageNamed:theImagePath];
cell.imageView.layer.masksToBounds = YES;
cell.imageView.layer.cornerRadius = 5.0;
cell.imageView.image = theImage;
//cell.image = [theImage imageScaledToSize:CGSizeMake(38, 38)];
//NSLog(@"%@", theImage);
}
// If there is no images in the album, display generic picture
if (imagesCount == 0) {
UIImage *theImage = [UIImage imageNamed:@"noalbumimages"];
cell.imageView.image = theImage;
//NSLog(@"%@", theImage);
}
}
return cell;
}
Thanks again.
再次感谢。

- (CGFloat)tableView:(UITableView *)tableView heightForRowAtIndexPath:(NSIndexPath *)indexPath
{
UITableViewCell *cell=(UITableViewCell *)[tableView cellForRowAtIndexPath:indexPath];
if(cell)
{
return cell.imageView.size.height+10;
}
else
{
return 44; //Return any default size you want
}
}
// returns nil if cell is not visible or index path is out of range
// 如果单元格不可见或索引路径超出范围，则返回 nil
check this method. find what what u got cell.imageview or cell.image find the height of that image here and set here. this is the method that return the size of the cell.
检查这个方法。找到你得到的东西 cell.imageview 或 cell.image 在此处找到该图像的高度并在此处设置。这是返回单元格大小的方法。

Shayam's answer is a little outdated and no longer compiles.
Shayam 的回答有点过时，不再编译。
Also, if you fix it you'll be likely to create an endless loop. As Oded Regev mentioned, this is not the way to do it.
此外，如果您修复它，您可能会创建一个无限循环。正如 Oded Regev 所提到的，这不是这样做的方法。
