 NSString* text = @"this is a simple uilabel sample";    UILabel* label = [[UILabel alloc] initWithFrame:CGRectZero];    label.backgroundColor = [UIColor redColor];    CGFloat width = 300.0;    UIFont*  font = [UIFont systemFontOfSize:30.0];    label.font = font;    label.numberOfLines = 0;    label.lineBreakMode = UILineBreakModeWordWrap;    label.text = text;    // 方法一,用文字来确定//    CGSize size = [text sizeWithFont:font constrainedToSize:CGSizeMake(width, 2000.0) lineBreakMode:UILineBreakModeWordWrap];    // 方法二,自适应    CGSize size = [label sizeThatFits:CGSizeMake(width, 2000.0)];        label.frame = CGRectMake(0, 0, size.width, size.height);        [self.view addSubview:label];
