UIButton无图实现背影色

 

UIButton *updateButton = [UIButton buttonWithType:UIButtonTypeRoundedRect];

    updateButton.frame = CGRectMake(20, 200, GNDEVICE_SCREEN_WIDTH-40, 40);

    [updateButton.layer setCornerRadius:4.0];

    updateButton.layer.borderColor = [UIColor colorWithRed:251/255.0 green:168/255.0 blue:42/255.0 alpha:1.0].CGColor;

    [updateButton setBackgroundColor:[UIColor colorWithRed:251/255.0 green:168/255.0 blue:42/255.0 alpha:1.0]];

    [updateButton setTitle:MY_Local_Str(@"版本更新") forState:UIControlStateNormal];

    [updateButton setTitleColor:[UIColor whiteColor] forState:UIControlStateNormal];

    [updateButton setTitleColor:[UIColor grayColor] forState:UIControlStateSelected];

    [updateButton setTitleColor:[UIColor grayColor] forState:UIControlStateHighlighted];

    updateButton.titleLabel.font = [UIFont boldSystemFontOfSize:18.0f];

    [updateButton addTarget:self action:@selector(checkHaveNewVersion_Func) forControlEvents:UIControlEventTouchUpInside];

    [self.view addSubview:updateButton];

达到的效果如下:
