Examples
Simple initialization:
BTLabel *label = [[BTLabel alloc] initWithFrame:CGRectMake(10, 10, 300, 80) edgeInsets:UIEdgeInsetsMake(10, 20, 10, 10)];
label.font = [UIFont preferredFontForTextStyle:UIFontTextStyleBody];
label.verticalAlignment = BTVerticalAlignmentCenter;
label.textAlignment = NSTextAlignmentLeft;Using within UITableViewCell:
// in interface
@property (nonatomic, strong) NSArray *texts;
@property (nonatomic, strong) UIFont *font;
@property (nonatomic, assign) UIEdgeInsets edgeInsets;
// in implementation
- (void)viewDidLoad
{
[super viewDidLoad];
self.texts = @[
@"Text for row 0",
@"Text for row 1",
@"Text for row 2",
];
self.font = [UIFont preferredFontForTextStyle:UIFontTextStyleBody];
self.edgeInsets = UIEdgeInsetsMake(10, 20, 10, 10);
}
- (CGFloat)tableView:(UITableView *)tableView heightForRowAtIndexPath:(NSIndexPath *)indexPath
{
return [BTLabel heightForWidth:tableView.bounds.size.width
text:self.texts[indexPath.row]
font:self.font
edgeInsets:self.edgeInsets
numberOfLines:0
imageSize:CGSizeZero
imagePosition:UIRectEdgeTop
imageEdgeInsets:UIEdgeInsetsZero] + 1;
}
- (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath
{
static NSString * const kCellID = @"kCellID";
UITableViewCell *cell = [tableView dequeueReusableCellWithIdentifier:kCellID];
if (!cell) {
cell = [[UITableViewCell alloc] initWithStyle:UITableViewCellStyleDefault reuseIdentifier:kCellID];
BTLabel *label = [[BTLabel alloc] initWithFrame:cell.bounds];
label.tag = 100;
label.autoresizingMask = UIViewAutoresizingFlexibleWidth | UIViewAutoresizingFlexibleHeight;
label.font = self.font;
label.textAlignment = NSTextAlignmentLeft;
label.verticalAlignment = BTVerticalAlignmentTop;
label.edgeInsets = self.edgeInsets;
label.hasImage = NO;
[cell.contentView addSubview:label];
}
BTLabel *label = [cell viewWithTag:100];
label.text = self.texts[indexPath.row];
return cell;
}
