代碼如下：
UIView* footerView = [[UIView alloc] initWithFrame: CGRectMake(10,100,300,180)];
UILabel* label = [[UILabel alloc] initWithFrame: CGRectMake(10,100,300,150)];
label.text = @"Helloworld!Helloworld!Helloworld!Helloworld!Helloworld!Helloworld!!";
label.backgroundColor = [UIColor redColor];
label.textColor = [UIColorwhiteColor];
label.textAlignment = UITextAlignmentCenter;
label.lineBreakMode = UILineBreakModeWordWrap;
label.numberOfLines = 0;
希望對你有幫助含长！
