SYActionSheetView实现了类似于UIActionSheet的效果，简单易用，完美支持IOS5.0及以上版本。
用法：
SYActionSheetView *actv = [[SYActionSheetView alloc] initWithTitle:nil cancelButtonTitle:@"cancle"
otherButtonTitles:@"action1",@"action2",nil];
actv.syActionSheetActionBlock = ^(UIButton *actionBtn){
if (actionBtn.tag == kBtnCaccleTag + 1)
{
SYLog(@"%@",actionBtn.titleLabel.text);
}
else if (actionBtn.tag == kBtnCaccleTag + 2)
{
SYLog(@"%@",actionBtn.titleLabel.text);
}
};
[actv showSYActionSheet];
