XWScanImage 是一個自定義的類, 評論留Q 發

ImageView = [[UIImageView alloc]init];

ImageView.backgroundColor = SetColor(160, 160, 160);

//為UIImageView1添加點擊事件

UITapGestureRecognizer *tapGestureRecognizer1 = [[UITapGestureRecognizer alloc] initWithTarget:self action:@selector(scanBigImageClick1:)];

[ImageView addGestureRecognizer:tapGestureRecognizer1];

#pragma mark 圖片的點擊放大縮小

-(void)scanBigImageClick1:(UITapGestureRecognizer *)tap{

NSLog(@"點擊圖片");

UIImageView *clickedImageView = (UIImageView *)tap.view;

[XWScanImage scanBigImageWithImageView:clickedImageView];

}

iOS 圖片點擊放大, 再次點擊縮小
