這是我迄今爲止。我試圖做的是有一個頂部的滾動條上帶有按鈕,帶你到不同的頁面。我在這裏添加了這個UIScrollView和按鈕,但我無法讓它顯示在屏幕上。我想要頂部滾動爲500像素(以適應其他按鈕),我希望我有那裏的按鈕在啓動時在屏幕中間。我認爲我的問題與我已經提出的座標有關,但我現在已經改變了他們幾個小時,我仍然無法得到它。我的UIScrollView不工作
// init top Scroller
UIScrollView *topScroll = [[UIScrollView alloc]initWithFrame:CGRectMake(-90,0, 60, 500)];
topScroll.contentSize = CGSizeMake(60,500);
topScroll.showsHorizontalScrollIndicator = YES;
[self.view addSubview:topScroll];
[topScroll setScrollEnabled:YES];
//add current games button
UIButton *currentGamesButton = [UIButton buttonWithType:UIButtonTypeRoundedRect];
currentGamesButton.frame = CGRectMake (227, 0,55,55);
[currentGamesButton addTarget:self
action:@selector(goToCurrentGamesViewController:)
forControlEvents:UIControlEventTouchUpInside];
[currentGamesButton setTitle:@"Current Games" forState:UIControlStateNormal];
[topScroll addSubview:currentGamesButton];
如果您的滾動視圖寬度爲60px,位於視圖左側-90px,我想這就是爲什麼你沒有看到它。 – SuperRod 2012-03-30 04:30:10

它上下滾動...我怎麼改變它,讓它滾動左右? – nfoggia 2012-03-30 04:33:54
