Question

我在“伊默勒”一案中有一例“UIImage”,我想将这一形象传给“人民抵抗力量”囚犯,这样,移徙才有可能吗? 我没有这样做的想法。

Answer 1

如果您有UIImage 意见书,则采用这种方法:

-(NSData*)makePDFfromView:(UIView*)view
{
    NSMutableData *pdfData = [NSMutableData data];

    UIGraphicsBeginPDFContextToData(pdfData, view.bounds, nil);
    UIGraphicsBeginPDFPage();
    CGContextRef pdfContext = UIGraphicsGetCurrentContext();
    [view.layer renderInContext:pdfContext];
    UIGraphicsEndPDFContext();

    return pdfData;
}

类似情况:

NSData *pdfData = [self makePDFfromView:imgView];
//[pdfData writeToFile:@"myPdf.pdf" atomically:YES]; - save it to a file

Answer 2

它不是非常困难的,但有一些步骤来确立一切。从根本上说,你需要创建人民抵抗力量的图表背景,然后用标准绘图指令加以利用。简单地将UIImage带入人民抵抗力量,你可以做如下事情:

// assume this exists and is in some writable place, like Documents
NSString* pdfFilename = /* some pathname */

// Create the PDF context
UIGraphicsBeginPDFContextToFile(pdfFilename, CGRectZero, nil); // default page size
UIGraphicsBeginPDFPageWithInfo(CGRectZero, nil);

// Draw the UIImage -- I think PDF contexts are flipped, so you may have to
// set a transform -- see the documentation link below if your image draws
// upside down
[theImage drawAtPoint:CGPointZero];

// Ending the context will automatically save the PDF file to the filename
UIGraphicsEndPDFContext();
