动态gif

// 设定位置和大小

CGRect frame = CGRectMake(50,50,0,0);
frame.size = [UIImage imageNamed:@"anim.gif"].size;
// 读取gif图片数据
NSData *gif = [NSData dataWithContentsOfFile:
[[NSBundle mainBundle] pathForResource:@"anim" ofType:@"gif"]];
// view生成
UIWebView *view = [[UIWebView alloc] initWithFrame:frame];
[view loadData:gif MIMEType:@"image/gif" textEncodingName:nil baseURL:nil];

1 UIView全局拍照
- (UIImage *) screenImage:(UIView *)view {
    UIImage *screenImage;
    UIGraphicsBeginImageContext(view.frame.size);
    [view.layer renderInContext:UIGraphicsGetCurrentContext()];
    screenImage = UIGraphicsGetImageFromCurrentImageContext();
    UIGraphicsEndImageContext();
    return screenImage;
}

2 UIView局域拍照
- (UIImage *) screenImage:(UIView *)view rect:(CGRect)rect {
    CGPoint pt = rect.origin;
    UIImage *screenImage;
    UIGraphicsBeginImageContext(rect.size);
    CGContextRef context = UIGraphicsGetCurrentContext();
    CGContextConcatCTM(context,
            CGAffineTransformMakeTranslation(-(int)pt.x, -(int)pt.y));
    [view.layer renderInContext:context];
    screenImage = UIGraphicsGetImageFromCurrentImageContext();
    UIGraphicsEndImageContext();

NSData *imagedata = UIImagePNGRepresentation(anImage);

NSArray *documentArr = NSSearchPathForDirectoriesInDomains

(NSDocumentDirectory, NSUserDomainMask, YES);

NSLog(@"%@",[documentArr objectAtIndex:0]);

NSString *filePath = [[documentArr objectAtIndex:0]stringByAppendingString:@"/image.png"];

[imagedata writeToFile:filePath atomically:YES];

UIImage *ima = [UIImage imageWithData:imagedata];

return screenImage;
}

UIImage*image = [UIImage imageNamed:@"suggest"];
    NSData *data = UIImagePNGRepresentation(image);

    MFMailComposeViewController *suggestMail = [[MFMailComposeViewController alloc]init];
    if (suggestMail) {
        suggestMail.mailComposeDelegate = self;
        //设置收件人
        [suggestMail setToRecipients:[NSArray arrayWithObjects:@"@qq.com",nil]];
        //设置抄送人
        [suggestMail setCcRecipients:nil];
        //设置邮件内容
        [suggestMail setMessageBody:@"反馈建议：" isHTML:YES];
        [suggestMail setSubject:@"反馈建议"];
        //设置邮件附件{mimeType:文件格式|fileName:文件名}
        [suggestMail addAttachmentData:data mimeType:@"png" fileName:@"日志.png"];
        //设置邮件视图在当前视图上显示方式
        [self presentViewController:suggestMail animated:YES completion:nil];


    }
