我有一个要求,我必须在网格视图中将图像视图从当前位置动画化到全屏。我将图像制作成网格视图。
- (void)viewDidLoad
{
[super viewDidLoad];
imagesArray = [[NSMutableArray alloc] init];
for (int i=1; i<11; i++) {
[imagesArray addObject:[UIImage imageNamed:[NSString stringWithFormat:@"image%d.png", i]]];
NSLog(@"imagesArray:%@", imagesArray);
}
float horizontal = 20.0;
float vertical = 20.0;
for(int i=0; i<[imagesArray count]; i++)
{
if((i%3) == 0 && i!=0)
{
horizontal = 20.0;
vertical = vertical + 220.00 + 20.0;
}
imagesView = [[UIImageView alloc] initWithFrame:CGRectMake(horizontal, vertical, 310.0, 220.00)];
imagesView.userInteractionEnabled = YES;
[imagesView setImage:[imagesArray objectAtIndex:i]];
imagesView.tag = i;
UITapGestureRecognizer *tap = [[UITapGestureRecognizer alloc] initWithTarget:self action:@selector(handleTap:)];
tap.numberOfTapsRequired = 1;
tap.numberOfTouchesRequired = 1;
[imagesView addGestureRecognizer:tap];
[self.view addSubview:imagesView];
horizontal = horizontal + 310.0 + 20.0;
}
}
在这里,我创建了带有图像的网格视图,就像我有 10 个图像一样。我制作了 3x3 网格视图。
接下来我向它添加了点击手势,我通过使用标签调用来获取图像视图位置
-(void)handleTap:(UITapGestureRecognizer *)recognizer
{
UIView *piece = recognizer.view;
[UIView animateWithDuration:1.0 animations:^{
piece.frame = CGRectMake(piece.frame.origin.x, piece.frame.origin.y, 1000, 700);
} completion:^(BOOL finished) {
}];
}
你能告诉我如何通过点击它使图像视图从当前位置动画到全屏。
