我正在尝试使用页面在水平行中显示图像,每页包含 4 个图像,可能由一行的一小段空间隔开或没有空格。当用户水平滚动时,接下来的四个图像将显示在视图的中心。但是使用这段代码:
UIScrollView *scroll = [[UIScrollView alloc] initWithFrame:CGRectMake(0, screenHeight/4, screenWidth, screenHeight/4)];
scroll.showsHorizontalScrollIndicator = YES;
scroll.showsVerticalScrollIndicator=NO;
scroll.pagingEnabled = YES;
NSInteger numberOfViews = 3;
int k=1;
for (int i = 0; i < numberOfViews; i++) {
CGFloat xOrigin = i * self.view.frame.size.width;
UIView *awesomeView = [[UIView alloc] initWithFrame:CGRectMake(xOrigin, 0, self.view.frame.size.width, self.view.frame.size.height)];
awesomeView.backgroundColor = [UIColor colorWithRed:0.5/i green:0.5 blue:0.5 alpha:1];
[scroll addSubview:awesomeView];
for (int j=0; j<4; j++) {
NSString *imageName = [NSString stringWithFormat:@"image%d.png", k];
UIImage *image = [UIImage imageNamed:imageName];
UIImageView *imageView = [[UIImageView alloc] initWithImage:image];
CGRect imageFrame=CGRectMake(0, k*screenHeight/4, screenWidth/5, screenHeight/5);
imageView.frame=imageFrame;
[awesomeView addSubview:imageView];
k++;
}
图像在第一页视图上垂直显示。此外,看起来垂直滚动正在工作。我错过了什么?
