UIPasteboard代碼？

Question

有沒有辦法將這段代碼放在UIPasteboard？

[TEXTFeild setLeftViewMode:UITextFieldViewModeAlways]; 

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

Answer 1

要分享圖片到粘貼板使用這樣的：

//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]; 

，並在粘貼前將圖像縮放：

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)]; 
} 

此代碼縮放圖像到1080px X 1080px如果大於1080x1080。

更新：該方法來自UIImage類別，稱爲UIImage+SimpleResize。將它添加到你的項目中，你很好走。
