嘗試使用NSAttributedString希望支持多種字體和文本大小，並使用\ n返回到下一行。

NSDictionary *italicAttrs = @{NSFontAttributeName : [UIFont fontWithName:@"HelveticaNeue-Bold" size:16], NSForegroundColorAttributeName : [UIColor colorWithRed:0.0 green:122.0/255.0 blue:1.0 alpha:1.0]}; 

    NSDictionary *defaultAttrs = @{NSFontAttributeName : [UIFont fontWithName:@"HelveticaNeue-Medium" size:16], NSForegroundColorAttributeName : [UIColor blackColor]}; 

    NSDictionary *arrowAttrs = @{NSFontAttributeName : [UIFont fontWithName:@"AlNile-Bold" size:20], NSForegroundColorAttributeName : [UIColor grayColor]}; 


    NSMutableAttributedString *labelText = [[NSMutableAttributedString alloc] init]; 

    NSAttributedString *from = [[NSAttributedString alloc] initWithString:@"From: " attributes:italicAttrs]; 

    NSAttributedString *content = [[NSAttributedString alloc] initWithString:@"Me\n" attributes:defaultAttrs]; 

    NSAttributedString *arrow = [[NSAttributedString alloc] initWithString:@"Ok" attributes:arrowAttrs]; 


    [labelText appendAttributedString:from]; 
    [labelText appendAttributedString:content]; 
    [labelText appendAttributedString:arrow];
