我正在尝试创建多页 PDF。我已经关注了这个tutorial . 这是使用静态文本的 XIB 文件,然后从代码中添加一个表。但是我有 ATM 的问题是,当表格大于一页时。当表格超过 9 行时。它应该在下一页继续。
这就是我在代码中所做的。
+(void)drawPDF:(NSString*)fileName
{
NSMutableDictionary *mutDictValues = [[[NSUserDefaults standardUserDefaults] objectForKey:@"dicValues"] mutableCopy];
NSMutableArray *arrSelectedCities = [[mutDictValues objectForKey:@"cities"]mutableCopy ];
if(arrSelectedCities.count <= 8){
// If there are only 8 rows --> we can fit everyting on one page !
// Create the PDF context using the default page size of 612 x 792.
UIGraphicsBeginPDFContextToFile(fileName, CGRectZero, nil);
// Mark the beginning of a new page.
UIGraphicsBeginPDFPageWithInfo(CGRectMake(0, 0, 612, 792), nil);
[self drawLabels];
[self drawLogo];
int xOrigin = 50;
int yOrigin = 350;
int rowHeight = 50;
int columnWidth = 240;
int numberOfRows = 9;
int numberOfColumns = 2;
[self drawTableAt:CGPointMake(xOrigin, yOrigin) withRowHeight:rowHeight andColumnWidth:columnWidth andRowCount:numberOfRows andColumnCount:numberOfColumns];
[self drawTableDataAt:CGPointMake(xOrigin, yOrigin) withRowHeight:rowHeight andColumnWidth:columnWidth andRowCount:numberOfRows andColumnCount:numberOfColumns withArray:arrSelectedCities];
// Close the PDF context and write the contents out.
UIGraphicsEndPDFContext();
}else{
// When we have more then 8 rows we should have 2 pages.
NSLog(@"Create 2 pages");
// Create the PDF context using the default page size of 612 x 792.
UIGraphicsBeginPDFContextToFile(fileName, CGRectZero, nil);
// Mark the beginning of a new page.
UIGraphicsBeginPDFPageWithInfo(CGRectMake(0, 0, 612, 792), nil);
[self drawLabels];
[self drawLogo];
int xOrigin = 50;
int yOrigin = 350;
int rowHeight = 50;
int columnWidth = 240;
int numberOfRows = 9;
int numberOfColumns = 2;
[self drawTableAt:CGPointMake(xOrigin, yOrigin) withRowHeight:rowHeight andColumnWidth:columnWidth andRowCount:numberOfRows andColumnCount:numberOfColumns];
[self drawTableDataAt:CGPointMake(xOrigin, yOrigin) withRowHeight:rowHeight andColumnWidth:columnWidth andRowCount:numberOfRows andColumnCount:numberOfColumns withArray:arrSelectedCities];
// Create the PDF context using the default page size of 612 x 792.
UIGraphicsBeginPDFContextToFile(fileName, CGRectZero, nil);
// Mark the beginning of a new page.
UIGraphicsBeginPDFPageWithInfo(CGRectMake(0, 0, 612, 792), nil);
int xOrigin2 = 50;
int yOrigin2 = 60;
int numberOfRows2 = ((arrSelectedCities.count+1)-9);
[self drawTableAt:CGPointMake(xOrigin2, yOrigin2) withRowHeight:rowHeight andColumnWidth:columnWidth andRowCount:numberOfRows2 andColumnCount:numberOfColumns];
[self drawTableDataAt:CGPointMake(xOrigin2, yOrigin2) withRowHeight:rowHeight andColumnWidth:columnWidth andRowCount:numberOfRows2 andColumnCount:numberOfColumns withArray:arrSelectedCities];
}
// Close the PDF context and write the contents out.
UIGraphicsEndPDFContext();
}
让我解释一下我在这里做什么。我有一个应该填满我的表格 View 的数组。如果数组大于 8,那么我应该使用 2 页。否则一切都适用于一页。
它的作用是,它只创建第二页....
谁能帮帮我?
最佳答案
创建第二页时,您不应再次调用 UIGraphicsBeginPDFContextToFile()
,
只有 UIGraphicsBeginPDFPageWithInfo()
:
UIGraphicsBeginPDFContextToFile(...);
UIGraphicsBeginPDFPageWithInfo(...); // start first page
// ...
UIGraphicsBeginPDFPageWithInfo(...); // start second page
// ...
UIGraphicsEndPDFContext();
