Unity3D4.6 UIButton怎么修改Button背景颜色？

btnObj.GetComponent<Image>().color= new (255,24,24,255);
我想改变Button 的颜色，怎么改不了啊，非常明确的知道这个按钮，怎么用代码实现背景颜色的修改，
求教？
谢谢！

Answer 1

UIButton *touristBtn = [[UIButton alloc]initWithFrame:CGRectMake(20, 5, 120, 25)];
[touristBtn setBackgroundColor:[UIColor clearColor]];
[touristBtn setImage:[UIImage imageNamed:@"firstBtn.png"] forState:UIControlStateNormal];
[touristBtn setImage:[UIImage imageNamed:@"secondBtn.png" forState:UIControlStateSelected];
[touristBtn addTarget:self action:@selector(touristEvent:) forControlEvents:UIControlEventTouchUpInside];
[tabView addSubview:touristBtn];

在button的action方法中改变button的状态：

-(void)touristEvent:(id)sender{
UIButton *button = (UIButton *)sender;
button.selected = !button.selected;
}
