ios开发怎么设置button的背景色

Answer 1

1.通过按钮的事件来设置背景色
- (void)viewDidLoad {
[super viewDidLoad];

UIButton *button1 = [[UIButton alloc] initWithFrame:CGRectMake(50, 200, 100, 50)];
[button1 setTitle:@"button1" forState:UIControlStateNormal];
button1.backgroundColor = [UIColor orangeColor];
[button1 addTarget:self action:@selector(button1BackGroundHighlighted:) forControlEvents:UIControlEventTouchDown];
[button1 addTarget:self action:@selector(button1BackGroundNormal:) forControlEvents:UIControlEventTouchUpInside];
[self.view addSubview:button1];
}

// button1普通状态下的背景色
- (void)button1BackGroundNormal:(UIButton *)sender
{
sender.backgroundColor = [UIColor orangeColor];
}

// button1高亮状态下的背景色
- (void)button1BackGroundHighlighted:(UIButton *)sender
{
sender.backgroundColor = [UIColor greenColor];
}
