ImageTextButton是继承于UIButton的按钮，包含图片和文字，有四种常见的布局类型，只需要简单地设置属性UIButtonTitleWithImageAlignment即可实现很常用的图文并排的按钮，容易拓展。以后大家就可以不用自定义view、image、title、button来实现这样一个效果了。
利用的方法也是UIButton本身的固有属性UIEdgeInsets，设置图片和文字的相对位置，以达到常用的图文并排的按钮效果。
使用方法：
在需要用到的地方：
#import "ImageTextButton.h"
@property (nonatomic, strong) ImageTextButton *imgTextB
2. 直接调用
self.imgTextButton = [[ImageTextButton alloc] initWithFrame:CGRectMake((self.view.frame.size.width - 150) / 2, 200, 150, 100)
image:[UIImage imageNamed:@"buttonImg.png"]
title:@"点我"];
self.imgTextButton.imgTextDistance = 10; // 可修改图片标题的间距，默认为5
self.imgTextButton.buttonTitleWithImageAlignment = UIButtonTitleWithImageAlignmentUp;
[self.imgTextButton addTarget:self action:@selector(changeValue:) forControlEvents:UIControlEventTouchUpInside];
[self.view addSubview:self.imgTextButton];
