是否可以通過電子郵件發送UIView？

Question

我的應用程序借鑑了UIView，我想通過電子郵件發送此圖。這可能嗎？

Answer 1

將其轉換爲圖像並將該圖像作爲附件發送。

+ (UIImage *) imageWithView:(UIView *)view 
{ 
    UIGraphicsBeginImageContextWithOptions(view.bounds.size, view.opaque, [[UIScreen mainScreen] scale]); 
    [view.layer renderInContext:UIGraphicsGetCurrentContext()]; 
    UIImage * img = UIGraphicsGetImageFromCurrentImageContext(); 
    UIGraphicsEndImageContext(); 
    return img; 
} 

-(void)displayComposerSheet 
{ 
    MFMailComposeViewController *picker = [[MFMailComposeViewController alloc] init]; 
    picker.mailComposeDelegate = self; 
    [picker setSubject:@"Check out this image!"]; 

    // Set up recipients 
    // NSArray *toRecipients = [NSArray arrayWithObject:@"first@example.com"]; 
    // NSArray *ccRecipients = [NSArray arrayWithObjects:@"second@example.com", @"third@example.com", nil]; 
    // NSArray *bccRecipients = [NSArray arrayWithObject:@"fourth@example.com"]; 

    // [picker setToRecipients:toRecipients]; 
    // [picker setCcRecipients:ccRecipients]; 
    // [picker setBccRecipients:bccRecipients]; 

    // Attach an image to the email 
    UIImage *coolImage = ...; 
    NSData *myData = UIImagePNGRepresentation(coolImage); 
    [picker addAttachmentData:myData mimeType:@"image/png" fileName:@"coolImage.png"]; 

    // Fill out the email body text 
    NSString *emailBody = @"My cool image is attached"; 
    [picker setMessageBody:emailBody isHTML:NO]; 
    [self presentModalViewController:picker animated:YES]; 

    [picker release]; 
}

你可以做到這一點只有當你將其轉換爲圖像。

轉換爲圖像

，您必須首先在鏈接QuartzCore框架，也#import <QuartzCore/QuartzCore.h>

下一頁插入到代碼：

UIGraphicsBeginImageContext(myView.bounds.size); 
[myView.layer renderInContext:UIGraphicsGetCurrentContext()]; 
UIImage *viewImage = UIGraphicsGetImageFromCurrentImageContext(); 
UIGraphicsEndImageContext();

發送電子郵件地址

您可以使用MFMailComposeViewController類，因此您不必離開您的應用程序。本教程幫助我：

要添加圖像，你可以使用同一個類的方法：addAttachmentData:mimeType:fileName:帶三個參數。檢查蘋果文件以獲取更多信息。
