}/***  监听按钮点击*/
- (void)buttonClick:(UIButton *)button

}// 设置按钮frame
- (void)layoutSubviews

}@end

在控制器中

- (void)addToolBar {HMComposeToolbar *toolbar = [[HMComposeToolbar alloc]init];toolbar.width = self.view.width;toolbar.height = 44;toolbar.y = self.view.height - toolbar.height;toolbar.delegate = self;[self.view addSubview:toolbar];self.toolbar = toolbar;
}
