Question

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;


}

再次感谢。

Answer 1

    - (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
 }
}

//如果单元格不可见或索引路径超出范围则返回nil

检查此方法。找到你得到的cell.imageview或cell.image 在这里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。

此致

Shayam的答案有点过时，不再编译。

另外，如果你修复它，你可能会创建一个无限循环。正如Oded Regev所说，这不是这样做的方式。
