@property(nonatomic,copy)NSString *text;//显示文字
@property(nonatomic,retain)UIFont *font;//字体
@property(nonatomic,retain)UIColor *textColor;//文字颜色

UIFont代表字体,常见的创建方法
+(UIFont *)systemFontOfSize:(CGFloat)fontSize;//系统默认字体
+(UIFont *)boldSystemFontOfSize:(CGFloat)fontsize;//粗体
+(UIFont *)italicSystemFontOfSize:(CGFloat)fontSize;//斜体
UIButton的常见设置
-(void)setTitle:(NSString *)title forState:(UIControlState)state;//设置按钮的文字
-(void)setTitleColor:(UIColor *)color forState:(UIControlState)state;//设置按钮的颜色

-(voif)setBackgroundImag:(UIImage *)image forState:(UIControlState)state;//设置按钮的背景图片
