//给某个按钮上的数字设置大小

+ (void)setDefaultFont:(id)sender size:(float)size{

[sender setFont:[UIFont fontWithName:@"Helvetica" size:size]];

}

-(void)initButton

{

UIButton *rightButton = [[UIButton alloc] initWithFrame:CGRectMake(50, 100, 100, 50)];

[rightButton setTitleColor:[UIColor grayColor] forState:UIControlStateNormal];

rightButton.backgroundColor=[UIColor redColor];

//给按钮上的字设置大小

[Utils setDefaultFont:rightButton size:20];

[rightButton setTitle:@"完成" forState:UIControlStateNormal];

[self.view addSubview:rightButton];

}
