无法更改UIView帧大小

Question

我有一个自定义uiview,我正在尝试更新帧大小.点击后,我会在方法中这样做.调用该方法,帧值发生变化,但屏幕上没有任何反应!

if (!touched) {

        GameBox *box = (GameBox *)[self.view viewWithTag:40];

        [box setFrame:CGRectMake(20, 20, 100, 73)];
        NSLog(@"%f", box.frame.origin.x);
        markButton.enabled = NO;
        guessButton.enabled = NO;
        [self.view reloadInputViews];

        NSLog(@"The action bar should now be hidden");
    }
    else if (touched) {
        guessButton.enabled = YES;
        markButton.enabled = YES;
        [self.view reloadInputViews];
        NSLog(@"The action bar should now be visible");
    }

Answer 1

我猜你已经把自己的视频挂钩到UIView了Interface Builder.

为了更改UIView框架,在Interface Builder转到File Inspector和取消选中Use Autolayout,然后在代码中更改框架.

希望这可以帮助.

Answer 2

您需要在viewDidAppear(而不是viewDidLoad)中设置调整框架.

- (void) viewDidAppear:(BOOL)animated {
[super viewDidAppear:animated];

CGRect frame = self.tableView.frame;
frame.origin.y += 100.0;
frame.size.height -= 100.0;
self.tableView.frame = frame;
}

显然这与导航控制器中的表视图有关.
