Iphone 在For循环中使用performSelector？苹果手机

我有一个数组（在下面的代码中称为array），它包含许多MyView对象。我试图在For循环中迭代这些对象，并将它们逐个添加为子视图，每个延迟1秒后。下面代码的问题是，所有对象都是在延迟一秒钟后立即添加的。有人能建议我如何改正吗

先谢谢你

- (void)startMethod {

    for (MyView * myview in array) {

        [self performSelector:@selector(addSubView:) withObject:myview afterDelay:1];
    }
}

- (void)addSubView : (UIView *)view {
    [soundController playSound];
    [self.view addSubview:view];
}

执行循环的时间不足以延迟选择器的执行。例如，您可能需要延迟使用计数器

-(void)startMethod {
    NSUInteger i = 0;
    for (MyView * myview in array) {
        i += 1;
        [self performSelector:@selector(addSubView:)
                   withObject:myview
                   afterDelay:i];
    }
}

其实很简单,

- (void)startMethod {
    int seconds = 0;
    for (MyView * myview in array) {
        [self performSelector:@selector(addSubView:) withObject:myview afterDelay:++seconds];
    }
}

简单的解决方案是：在循环每次迭代后，将延迟增加1秒

- (void)startMethod {
    int seconds = 0;
    for (MyView * myview in array) {
        [self performSelector:@selector(addSubView:) withObject:myview afterDelay:++seconds];
    }
}
