我有一个产品详细信息列表作为NSMutableArray中的对象和产品图像列表作为图库,我需要在点击缩略图图像时加载完整图像。为此,我设置标签并在点击特定图像时获得精确的标签值。问题是我无法获取数组对象。我用手动数字测试,数组完美地返回对象。我在这里做错了什么?
标记设置代码:
for(int index=0; index < [self.sliderImages count]; index++)
{
UIImageView *imageView = [[UIImageView alloc]init];
imageView.frame = CGRectMake(xOffset, 0, 100, scrollHeight);
imageView.tag = index;
Products *product = [self.sliderImages objectAtIndex:index];
NSLog(@"product name %@",product.name);
NSString *imageUrl = [NSString stringWithFormat:@"%@",product.imagePath];
}
点击手势识别器方法:
- (void) tapGesture:(id)sender
{
//handle Tap...
UIImageView *tmp = (UIImageView *)[sender view];
int tm = (int)(tmp.tag);
NSLog(@"self.sliderImages%@",[self.sliderImages objectAtIndex:tm]);
Products *product = [self.sliderImages objectAtIndex:tm];
NSLog(@"product%@",product);
NSLog(@"product ges %@,, %@",product.name,product.imagePath);
NSString *imageUrl = [NSString stringWithFormat:@"%@",product.imagePath];
NSLog(@"full image path :: %@",imageUrl);
[self loadFullImage:tm];
}
答案 0 :(得分:0)
你确定你的标签中没有nil吗? (int tm =(int)(tmp.tag))
您如何获得UIImageView的点击次数?你在使用手势识别器吗?
如果您使用的是手势识别器,请尝试使用手势识别器来接收相同的触摸和标签
