提示框

自己写了一个hud，里面图片是通过代码画出来的，不需要其他资源文件

效果

有一下6种样式

image
image
image
image
image
image

使用

LYProgressHUD.showLoading()
LYProgressHUD.showInfo("")
LYProgressHUD.showError("")
LYProgressHUD.showSuccess("")
LYProgressHUD.showOnlyText("")
LYProgressHUD.showStatusBarWithText(text: "")
LYProgressHUD.showWaitingWithImages(images: Array<UIImage>())
