突出顯示UILabel中的特定文本

Question

在我的應用程序中，我在我的標簽中顯示這樣的文本

cell.lblUserDetails.text=[NSString stringWithFormat:@"%@ and %@ other likes your post", [dictionary valueForKey:@"username"], [dictionary valueForKey:@"CuriousCount"]];

在這里，我想突出顯示Username和CuriousCount（紅色），還可以點擊用戶名和CuriousCount。

Answer 1

UIColor *color = [UIColor redColor];
NSDictionary *attrs = @{ NSForegroundColorAttributeName : color };
NSAttributedString *nameStr = [[NSAttributedString alloc] initWithString:[dictionary valueForKey:@"username"] attributes:attrs];
NSAttributedString *countStr = [[NSAttributedString alloc] initWithString:[dictionary valueForKey:@"CuriousCount"] attributes:attrs];

NSMutableAttributedString *string = [[NSMutableAttributedString alloc] init];
[string appendAttributedString:nameStr];
[string appendAttributedString:[[NSAttributedString alloc] initWithString:@" and "]];
[string appendAttributedString:countStr];
[string appendAttributedString:[[NSAttributedString alloc] initWithString:@" other likes your post"]];

cell.lblUserDetails.attributedText = string;
