Iphone 数组中的UIButton处理

我创建了一个按钮数组，但我看不到按钮处理触摸事件（buttonEvent:not调用）

这是我的代码-不正确吗

- (void)loadView{
CGRect screenRect = [[UIScreen mainScreen] applicationFrame];
UIImageView *backgroundImageView = [[UIImageView alloc] initWithFrame:screenRect];
[backgroundImageView setImage:[UIImage imageNamed:@"background.png"]];
backgroundImageView.opaque = YES;
self.view = backgroundImageView;
[backgroundImageView release];

CGRect brandRect = CGRectMake(90, 25, 140, 70);
UIImageView *brandImageView = [[UIImageView alloc] initWithFrame:brandRect];
[brandImageView setImage:[UIImage imageNamed:@"brand.png"]];
[self.view addSubview:brandImageView];
buttons = [NSMutableArray array];

int y = 100;
for ( int i = 0 ; i < 5; i++ ){
    UIButton *button = [UIButton buttonWithType:UIButtonTypeCustom];
    [button setFrame:CGRectMake(20, y, 280, 50)];
    if ( i == 0 ){
        [button setBackgroundImage:[UIImage imageNamed:@"select_active.png"] forState:UIControlStateNormal];
    } else {
        [button setBackgroundImage:[UIImage imageNamed:@"select_passive.png"] forState:UIControlStateNormal];
    }
    [button setTitle:[NSString stringWithFormat:@"Object%d",i] forState:UIControlStateNormal];
    [button setTitleColor:[UIColor blueColor] forState:UIControlStateNormal];
    [button addTarget:self action:@selector(buttonEvent:) forControlEvents:UIControlEventAllEvents];
    button.tag = 1000 + i ;
    [self.view addSubview:button];
    y += 60;
}

-(void)buttonEvent:(id)sender {
NSLog(@"new button clicked!!!");
}

-（无效）加载视图{
CGRect screenRect=[[UIScreen mainScreen]applicationFrame]；
UIImageView*backgroundImageView=[[UIImageView alloc]initWithFrame:screenRect]；
[backgroundImageView setImage:[UIImage ImageName:@“background.png”]；
backgroundImageView.不透明=是；
self.view=backgroundImageView；
[背景图像视图发布]；
CGRect-brandRect=CGRectMake（90,25,140,70）；
UIImageView*brandImageView=[[UIImageView alloc]initWithFrame:brandRect]；
[brandImageView setImage:[UIImage ImageName:@“brand.png”]；
[self.view addSubview:brandImageView]；
按钮=[NSMutableArray]；
int y=100；
对于（int i=0；i<5；i++）{
UIButton*button=[UIButton button类型：UIButtonTypeCustom]；
[按钮设置框：CGRectMake（20，y，280，50）]；
如果（i==0）{
[按钮setBackgroundImage:[UIImage ImageName:@“select_active.png”]用于状态：UIControlStateNormal]；
}否则{
[按钮setBackgroundImage:[UIImage ImageName:@“select_passive.png”]用于状态：UIControlStateNormal]；
}
[按钮集标题：[NSString stringWithFormat:@“对象%d”，i]用于状态：UIControlStateNormal]；
[按钮设置标题颜色：[UIColor blueColor]用于状态：uicontrol状态正常]；
[按钮添加目标：自我操作：@选择器（按钮事件：）用于控制事件：UIControlEventAllEvents]；
button.tag=1000+i；
[self.view addSubview:按钮]；
y+=60；
}
-（无效）按钮事件：（id）发件人{
NSLog（@“单击新按钮！！！”）；
}

您正在向uiimageview添加按钮，uiimageview已禁用交互功能

此外，您没有按钮数组，因为按钮是自动删除的，并且您从未将对象添加到按钮数组中。

我找到了解决方案-backgroundImageView.userInteractionEnabled=是解决了我的问题
