UIPasteboard 的代码？

Question

有没有办法将此代码放在 UIPasteboard 中？

[TEXTFeild setLeftViewMode:UITextFieldViewModeAlways];

UIImageView *imageView1 = [[UIImageView alloc] initWithFrame:CGRectMake(0, 0, 22, 22)];
imageView1.image = image;
TEXTFeild.leftView = imageView1;

Answer 1

要将图像分享到粘贴板，请使用：

//Method 1
UIImage * image=[UIImage imageWithContentsOfFile:@"FILE_PATH"];
UIPasteboard * pasteboard=[UIPasteboard generalPasteboard];
[pasteboard setImage:image];

//Method 2
NSData *imageData = UIImagePNGRepresentation(image);
[pasteboard setData:imageData forPasteboardType:(NSString *)kUTTypePNG];

并在粘贴前缩放图像：

CGFloat image_max_height = 1080;
CGFloat image_max_width = 1080;

UIImage *finalImage = image;

if (image.size.width>image_max_width || image.size.height>image_max_height) {
    finalImage = [image imageByScalingAspectFitSize:CGSizeMake(image_max_width, image_max_height)];
}

如果图像大于 1080x1080，此代码会将图像缩小到 1080px x 1080px。

更新： 该方法来自名为 UIImage+SimpleResize 的 UIImage 类别。将它添加到您的项目中，一切顺利。
