UILabel TTTAttributedLabel

iOS學習_UILabel顯示兩種以上的顏色

iOS - Using TTTAttributedLabel to set two color text

[Objective-C][Library]TTTAttributedLabelをつかってみた！

UILabel turns nil in UITableViewCell

1. 下載程式碼

2. 將TTTAttributedLabel.h 與 TTTAttributedLabel.m加到你的專案中。

#import "TTTAttributedLabel.h"


3. 有開ARC 使用第三方的函數庫時 在Targets設定中的Build Phases選擇TTTAttributedLabel.m，按下Enter鍵並且輸入「-fno-objc-arc」關閉使用ARC

4. 加入CoreText.framework 到你的專案中。

#import <CoreText/CoreText.h>

Have you included CoreText.framework in your project?

5. 在你需要兩種以上顏色的UILabel換成TTTAttributedLabel

    CFRelease(italicFont);
    
    //紅字
    NSRange redRange = [text rangeOfString:@"名片"];
    [tttstring addAttribute:(NSString*)kCTForegroundColorAttributeName value:(id)[[UIColor redColor] CGColor] range:redRange];
    
    //底線
    NSRange underlinRange = [text rangeOfString:@"請多指教"];
    [tttstring addAttribute:(NSString *)kCTUnderlineStyleAttributeName value:[NSNumber numberWithBool:YES] range:underlinRange];
    
    //組體
    UIFont *boldSystemFont = [UIFont boldSystemFontOfSize: 18] ;

    if(boldFont){
        [tttstring addAttribute:(NSString *)kCTFontAttributeName value:(__bridge id)boldFont range:underlinRange];
    }
    CFRelease(boldFont);
    
    
    masterLabel.frame = MASTER_RECT;
    masterLabel.numberOfLines = 1;
    [masterLabel setBackgroundColor:[UIColor clearColor]];//clearTextBackgroundColor!
    [masterLabel setText:tttstring];

    
    return cell;
}

 
#pragma mark -
#pragma mark custom cell view

- (UITableViewCell *) getCellContentView:(NSString *)cellIdentifier 
{
    CGRect cellFrame = (self.mainTableView.style == UITableViewStylePlain)?  CGRectMake(0, 0, 320, 58) : CGRectMake(0, 0, 300, 58);
    UITableViewCell *cell = [[UITableViewCell alloc] initWithStyle:UITableViewCellStyleDefault reuseIdentifier: cellIdentifier];
    cell.frame = cellFrame;
      
    
    TTTAttributedLabel *master = [[TTTAttributedLabel alloc] initWithFrame: MASTER_RECT];
 master.tag = 2;
 master.numberOfLines = 1;
 master.lineBreakMode = UILineBreakModeWordWrap;
    
    [master setFont: [UIFont fontWithName: @"HeiTi TC" size: 18]];
    

 [cell.contentView addSubview: master];

 return cell;
}

結果顯示
