我目前正在使用iOS 10和Swift 3开发应用程序
此应用程序的目的是制作包含我的UIWebview
内容的PDF文件它不起作用，我必须删除这些行来生成PDF。
DataTable
否则我们在IBAction中遇到了麻烦：
<div>
#Test#
</div>内存增加，如果它是一个infini循环
pdf未生成，我不明白为什么。
有人对此有所了解吗？
我不明白为什么？
如果有人有想法？
我迅速的IBAction：
for i in 1...render.numberOfPages {
UIGraphicsBeginPDFPage();
let bounds = UIGraphicsGetPDFContextBounds()
render.drawPage(at: i - 1, in: bounds)
}
这是我的CSS代码：
if let contentOpt = self.contentFile {
let fmt = UIMarkupTextPrintFormatter(markupText: contentOpt)
let render = UIPrintPageRenderer()
render.addPrintFormatter(self.webView.viewPrintFormatter(), startingAtPageAt: 0)
let page = CGRect(x: 0, y: 0, width: 595.2, height: 841.8) // A4, 72 dpi
let printable = page.insetBy(dx: 0, dy: 0)
render.setValue(NSValue(cgRect: page), forKey: "paperRect")
render.setValue(NSValue(cgRect: printable), forKey: "printableRect")
let pdfData = NSMutableData()
UIGraphicsBeginPDFContextToData(pdfData, CGRect.zero, nil)
print("Data ", pdfData)
for i in 1...render.numberOfPages {
UIGraphicsBeginPDFPage();
let bounds = UIGraphicsGetPDFContextBounds()
render.drawPage(at: i - 1, in: bounds)
}
UIGraphicsEndPDFContext();
let documentsPath = NSSearchPathForDirectoriesInDomains(.documentDirectory, .userDomainMask, true)[0]
print("PATH => \(documentsPath)")
pdfData.write(toFile: "\(documentsPath)/file.pdf", atomically: true)
}
