iOS 7 の最小バージョンでアプリを構築しています。セルを描画する方法では、このコードをUILabel使用してさまざまなUIFontsタイプで描画します。
//Get Strings
NSString* author = [self getUserCreatedVideo:notf];
NSString* caption = [NSString stringWithFormat:@"\"%@\"", [notf objectForKey:@"title"]];
NSString* challenge = @"challenged you to reply to";
NSString* timeToReply = @"24h to reply";
NSString* myString = [NSString stringWithFormat:@"%@ %@ %@ %@", author, challenge, caption, timeToReply];
NSMutableAttributedString *str = [[NSMutableAttributedString alloc] initWithString:myString];
UIColor* greenColor = [UIColor colorWithRed:102.0/255.0 green:204.0/255.0 blue:153.0/255.0 alpha:1];
//Author
[str addAttribute:NSForegroundColorAttributeName value:[UIColor darkGrayColor] range:NSMakeRange(0,author.length)];
[str addAttribute:NSFontAttributeName value: [UIFont fontWithName:@"Helvetica" size:17.0] range:NSMakeRange(0,author.length)];
//Challenge
[str addAttribute:NSForegroundColorAttributeName value:[UIColor lightGrayColor] range:NSMakeRange(author.length+1,challenge.length)];
[str addAttribute:NSFontAttributeName value: [UIFont fontWithName:@"Helvetica" size:13.0] range:NSMakeRange(author.length+1,challenge.length)];
//Caption
[str addAttribute:NSForegroundColorAttributeName value:[UIColor darkGrayColor] range:NSMakeRange(author.length+1+challenge.length+1,caption.length)];
[str addAttribute:NSFontAttributeName value: [UIFont fontWithName:@"Helvetica" size:14.0] range:NSMakeRange(author.length+1+challenge.length+1,caption.length)];
//Time To Reply
[str addAttribute:NSForegroundColorAttributeName value:greenColor range:NSMakeRange(author.length+1+challenge.length+1+caption.length+1,timeToReply.length)];
[str addAttribute:NSFontAttributeName value: [UIFont fontWithName:@"Helvetica" size:14.0] range:NSMakeRange(author.length+1+challenge.length+1+caption.length+1,4)];
cell.subtext.attributedText = str;
今私はテキストサイズを計算したいので、下に20pxUILabelを描くことができます。どうすればこれを達成できますか?UILabelcell.subtext
