iphone - 如何创建一个画廊来使用滑动手势显示照片？

Question

我在 NSArray 中有多张照片，我想用全尺寸的滑动手势显示它们，而不使用 Three20 。那么我该怎么做呢？

Answer 1

使用 ScrollView 来实现这一点:

UIScrollView * scroller = [[[UIScrollView alloc] initWithFrame:CGTectMake(0, 0, 320, 480)] autorelease];
scroller.pagingEnabled = YES;
[self.view addSubview:scroller];

int x = 0;

for (int i = 0; i < [yourArray count]; i++){

    UIImageView * myImageview = [[[UIImageView alloc] initWithFrame:CGRectMake(x, 0, 320, 480)] autorelease];
    [myImageview setImage:[yourArray objectAtIndex:i]];
    [scroller addSubview:myView];

    x += myView.frame.size.width;

}

[scroller setContentSize:CGSizeMake(x, 480)];
