本文将指导您如何使用Objective-C编程语言创建一个带有自定义背景图像和状态切换功能的圆角矩形按钮控件。

for (int i=0; i<9; i++) {
    UIButton *roundedRectButton = [UIButton buttonWithType:UIButtonTypeRoundedRect];    
    CGRect buttonRect = CGRectMake(18+(i%9%3)*105+(i/9)*320, 35+(i%9/3)*105, 80, 80);
    [roundedRectButton setFrame:buttonRect];
    //[roundedRectButton setTitle:@"Normal" forState:UIControlStateNormal];
    [roundedRectButton setTitle:@"Highlighted" forState:UIControlStateHighlighted];
    roundedRectButton.showsTouchWhenHighlighted = YES;
        [roundedRectButton setTag:i];
        [roundedRectButton setBackgroundImage:[UIImage imageNamed:@"logo.jpg"] forState:UIControlStateNormal];
    [roundedRectButton addTarget:self action:@selector(buttonDown:) forControlEvents:UIControlEventTouchDown];
    [self.view addSubview:roundedRectButton];
    }
