如何使用drawAtPoint绘制多行文本？

Question

我是自定义绘制一些文字:

point = CGPointMake(77, 5);
    [[message valueForKey:@"user_login"] drawAtPoint:point forWidth:200 
                                            withFont:mainFont 
                                         minFontSize:MIN_MAIN_FONT_SIZE 
                                      actualFontSize:NULL 
                                       lineBreakMode:UILineBreakModeTailTruncation 
                                  baselineAdjustment:UIBaselineAdjustmentAlignBaselines];

我该如何画5条线？相当于:

rect = CGRectMake(77, 25, 238, 68);
bodyLabel = [[UILabel alloc] initWithFrame:rect];
bodyLabel.font = [UIFont fontWithName:@"HelveticaNeue" size:12];
bodyLabel.numberOfLines = 5;
bodyLabel.lineBreakMode = UILineBreakModeWordWrap;
    bodyLabel.textColor = [UIColor blackColor];
    [self.contentView addSubview: bodyLabel];

说明-drawAtPoint:withFont:..."此方法在绘图期间不执行任何换行" 的文档.如果你使用-drawInRect:withFont:而不是-drawAtPoint:withFont:...,那么它将绘制多行.您还可以使用它-sizeWithFont:constrainedToSize:来确定尺寸.
