Iphone 以编程方式添加uibuttons

这里我有这个代码，我正在哪里尝试

openingHoursView.ohLocation

有两个值“value1”和“value2”。 使用值“id1”和“id2”的

openingHoursView.idNum

也是如此。 当我执行代码时，我只得到一个名为“value2”和“id2”的按钮。所以我的问题是如何为

openingHoursView.ohLocation

和

openingHoursView.idNum

- (void)loadView {

    storeAppDelegate = (StoreAppDelegate *)[[UIApplication sharedApplication] delegate];    

    int row = [storeAppDelegate.openingHoursLocationsDelegate count]-1;
    for (int i = 0; i <= row; i++) {
        openingHoursView = [storeAppDelegate.openingHoursLocationsDelegate objectAtIndex:i];

        self.view = [[UIView alloc] initWithFrame:[[UIScreen mainScreen] applicationFrame]];

        self.view.backgroundColor = [UIColor whiteColor];

        //create the button
        UIButton *button = [UIButton buttonWithType:UIButtonTypeRoundedRect];
        //set the position of the button
        if (i%2 != 0) {
            button.frame = CGRectMake(30 , 100 , 150, 30);

        }else {
            button.frame = CGRectMake(30 , 100 + i*50, 150, 30);
        }


        //set the button's title
        [button setTitle:openingHoursView.ohLocation forState:UIControlStateNormal];

        //listen for clicks
        [button addTarget:self action:@selector(buttonPressed:) forControlEvents:UIControlEventTouchUpInside];
        button.tag = [openingHoursView.idNum intValue];
        //add the button to the view
        [self.view addSubview:button];
    }
}

-(IBAction) buttonPressed: (id) sender {
    UIButton* button = (UIButton*)sender;

    NSLog(@"User clicked %d", button.tag);
    // Do something here with the variable 'sender'
}

-（无效）加载视图{
storeAppDelegate=（storeAppDelegate*）[[UIApplication sharedApplication]委托]；
int row=[storeAppDelegate.openingHoursLocationsDelegate计数]-1；
对于（int i=0；i而言，问题在于您正在执行：

self.view = [[UIView alloc] initWithFrame:[[UIScreen mainScreen] applicationFrame]];

self.view.backgroundColor = [UIColor whiteColor];

在
for
循环中，因此在每次迭代中都会被覆盖。在
for
循环之前，您应该只执行一次。
您正在为中的每个按钮创建一个新视图

self.view = [[UIView alloc] initWithFrame:[[UIScreen mainScreen] applicationFrame]];

将此代码放在for循环之前。
