我正在开发一个PDF Builder应用程序,并完成了本教程。
有没有办法在具有多个图像的单元格中添加一些文本。我尝试了不同的方法,但它导致 PDF 中的错误。
我试过这个:
let table = PDFTable()
let str = String(format: "Lorem Ipsum is simply dummy text of the printing and typesetting industry.")
let str1 = String(format: "Lorem Ipsum is simply dummy text of the printing and typesetting industry. nLorem Ipsum has been the industry's standard dummy text ever since the 1500s, when an unknown printer took a galley of type and scrambled it to make a type specimen book. nnIt has survived not only five centuries, but also the leap into electronic typesetting, remaining essentially unchanged. ")
do {
try table.generateCells(
data:[
["Name", "Image", "Description"],
[project.name + "n" + project.address1, UIImage(named: "demo")!, str],
[project.name + "n" + project.address1, UIImage(named: "demo")!, str1]
],
alignments: [
[.topLeft, .top, .top],
[.topLeft, .top, .top],
[.topLeft, .top, .top]
])
} catch PDFError.tableContentInvalid(let value) {
// In case invalid input is provided, this error will be thrown.
print("This type of object is not supported as table content: " + String(describing: (type(of: value))))
} catch {
// General error handling in case something goes wrong.
print("Error while creating table: " + error.localizedDescription)
}
table.widths = [
0.23, 0.30, 0.47
]
let style = PDFTableStyleDefaults.simple
table.style = style
do {
// Style each cell individually
try table.setCellStyle(row: 1, column: 0, style: PDFTableCellStyle(colors: (fill: UIColor.lightGray, text: UIColor.black)))
try table.setCellStyle(row: 1, column: 1, style: PDFTableCellStyle(colors: (fill: UIColor.lightGray, text: UIColor.black)))
try table.setCellStyle(row: 1, column: 2, style: PDFTableCellStyle(colors: (fill: UIColor.lightGray, text: UIColor.black)))
try table.setCellStyle(row: 2, column: 0, style: PDFTableCellStyle(colors: (fill: UIColor.lightGray, text: UIColor.black)))
try table.setCellStyle(row: 2, column: 1, style: PDFTableCellStyle(colors: (fill: UIColor.lightGray, text: UIColor.black)))
try table.setCellStyle(row: 2, column: 2, style: PDFTableCellStyle(colors: (fill: UIColor.lightGray, text: UIColor.black)))
} catch PDFError.tableIndexOutOfBounds(let index, let length){
// In case the index is out of bounds
print("Requested cell is out of bounds! (index) / (length)")
} catch {
// General error handling in case something goes wrong.
print("Error while setting cell style: " + error.localizedDescription)
}
table.padding = 1.0
table.margin = 2.0
table.showHeadersOnEveryPage = true
document.add(table: table)
我怎样才能找到解决方法?
很抱歉没有早点回复(不知何故我没有收到通知(。
- 尝试在表格单元格内使用组。
- 尝试新的表 api 和逻辑(仍在开发中,请参阅分支
