解决方法
您需要在项目中添加两个框架 – QuartzCore和MessageUI,然后执行#import< QuartzCore / QuartzCore.h>和#import< MessageUI / MessageUI.h>.
你的按钮代码应该是,像,
- (void)buttonPress:(id)sender
{
UIGraphicsBeginImageContext(self.view.frame.size);
[self.view.layer renderInContext:UIGraphicsGetCurrentContext()];
UIImage * image = UIGraphicsGetImageFromCurrentImageContext();
UIGraphicsEndImageContext();
NSData * imageData = UIImageJPEGRepresentation(image,1.0);
if ( [MFMailComposeViewController canSendMail] ) {
MFMailComposeViewController * mailComposer = [[[MFMailComposeViewController alloc] init] autorelease];
mailComposer.delegate = self;
[mailComposer addAttachmentData:imageData mimeType:@"image/jpeg" fileName:@"attachment.jpg"];
/* Configure other settings */
[self presentModalViewController:mailComposer animated:YES];
}
}
