1.把scrollView上面的内容生成PDF文件，代码如下：
- (NSString *)createPDF {
NSDate*printTime = [NSDatedate];
NSString*fileName = [NSStringstringWithFormat:@"%@_%@_%@.pdf",self.user.real_name,self.title, [self.dateHourMinuteFormatterstringFromDate:printTime]];
NSURL*storeURL = [selfbuildStoreURLForFileName:fileName];
NSString*storePath = storeURL.path;
CGFloatcontentViewWidth =CGRectGetWidth(self.scrollView.frame);
CGFloatcontentViewHeight =CGRectGetHeight(self.scrollView.frame);
CGFloatpageWidth = contentViewWidth;
CGFloatpageHeight = contentViewHeight +143.f;
UIGraphicsBeginPDFContextToFile(storePath,CGRectMake(0,0, pageWidth, pageHeight),nil);
NSString*dateText = [NSStringstringWithFormat:@"%@ (%d%@)",self.dataSelectView.label.text, (int)self.daysCount, (self.daysCount>1) ?MyLocalizedString(@"unit.days",nil) :MyLocalizedString(@"unit.day",nil)];
NSDictionary*pdmSettings = (NSDictionary*)self.user.settings.pdmSettings;
NSString*pdmSN =@"";
if([pdmSettingsobjectForKey:@"PDMSN"]) {
pdmSN = [AppDelegatetransformSerialString:[pdmSettingsobjectForKey:@"PDMSN"]];
}
NSString*pumpBaseSN =@"";
if([pdmSettingsobjectForKey:@"PumpBaseSN"]) {
pumpBaseSN = [AppDelegatetransformSerialString:[pdmSettingsobjectForKey:@"PumpBaseSN"]];
}
NSString*transmitterSN =@"";
if([pdmSettingsobjectForKey:@"TransmitterSN"]) {
transmitterSN = [AppDelegatetransformSerialString:[pdmSettingsobjectForKey:@"TransmitterSN"]];
}
NSUIntegerpageCount =0;
CGFloatsumWidth = contentViewWidth;
CGFloatsumHeight = contentViewHeight;
CGFloatheaderViewHight =0;
for(UIView*iteminself.scrollView.subviews) {
if(![itemisKindOfClass:[UIImageViewclass]]) {
for(UIView*viewinitem.subviews) {
if(pageCount ==0||CGRectGetMaxX(view.frame) > sumWidth ||CGRectGetMaxY(view.frame) > sumHeight) {
pageCount++;
if(CGRectGetMaxX(view.frame) > sumWidth) {
sumWidth += contentViewWidth;
}
if(CGRectGetMaxY(view.frame) > sumHeight) {
sumHeight += contentViewHeight;
}
UIGraphicsBeginPDFPage();
headerViewHight = [selfcreateHeaderViewWithWidth:pageWidthdateText:dateTextname:self.user.real_namepdmSN:pdmSNpumpBaseSN:pumpBaseSNtransmitterSN:transmitterSN];
[self createFooterViewWithWidth:pageWidth height:(pageHeight - 35) name:self.myDelegate.user.real_name ? self.myDelegate.user.real_name : self.myDelegate.user.username pageNumber:(unsigned int)pageCount printTime:printTime];
}
UIGraphicsBeginImageContextWithOptions(view.bounds.size, NO, 0.0);
[view.layer renderInContext:UIGraphicsGetCurrentContext()];
UIImage *image = UIGraphicsGetImageFromCurrentImageContext();
image = [selfadjustColor:image];
UIGraphicsEndImageContext();
[imagedrawInRect:CGRectMake(CGRectGetMinX(view.frame) - sumWidth + contentViewWidth,CGRectGetMinY(view.frame) + headerViewHight - sumHeight + contentViewHeight,CGRectGetWidth(view.frame),CGRectGetHeight(view.frame))];
}
}
}
UIGraphicsEndPDFContext();
returnstorePath;
}
2.把tableView上面的内容生成PDF文件，代码如下：
#pragma mark- Create PDF
- (NSString *)createPDF {
NSDate*printTime = [NSDatedate];
NSString*fileName = [NSStringstringWithFormat:@"%@_%@_%@.pdf",self.user.real_name,self.title, [self.dateHourMinuteFormatterstringFromDate:printTime]];
NSURL*storeURL = [selfbuildStoreURLForFileName:fileName];
NSString*storePath = storeURL.path;
CGFloatlayoutConstraintConstant =self.tableViewHeightConstraint.constant;
self.tableViewHeightConstraint.constant=self.tableView.contentSize.height-CGRectGetHeight(self.tableView.frame) + layoutConstraintConstant;
[self.tableView reloadData];
CGFloatpageWidth =self.tableView.contentSize.width;
// CGFloat pageHeight = self.tableView.contentSize.height + 143.f;
CGFloatpageHeight =self.tableView.sectionHeaderHeight+31*self.tableView.rowHeight+143.f;
UIGraphicsBeginPDFContextToFile(storePath,CGRectMake(0,0, pageWidth, pageHeight),nil);
NSString*dateText = [NSStringstringWithFormat:@"%@ (%d%@)",self.dataSelectView.label.text, (int)self.daysCount, (self.daysCount>1) ?MyLocalizedString(@"unit.days",nil) :MyLocalizedString(@"unit.day",nil)];
NSDictionary*pdmSettings = (NSDictionary*)self.user.settings.pdmSettings;
NSString*pdmSN =@"";
if([pdmSettingsobjectForKey:@"PDMSN"]) {
pdmSN = [AppDelegatetransformSerialString:[pdmSettingsobjectForKey:@"PDMSN"]];
}
NSString*pumpBaseSN =@"";
if([pdmSettingsobjectForKey:@"PumpBaseSN"]) {
pumpBaseSN = [AppDelegatetransformSerialString:[pdmSettingsobjectForKey:@"PumpBaseSN"]];
}
NSString*transmitterSN =@"";
if([pdmSettingsobjectForKey:@"TransmitterSN"]) {
transmitterSN = [AppDelegatetransformSerialString:[pdmSettingsobjectForKey:@"TransmitterSN"]];
}
NSUIntegerpageCount =0;
CGFloatcontentHeight =0;
CGFloatoffsetY =0;
do{
pageCount ++;
UIGraphicsBeginPDFPage();
CGFloatheaderViewHight = [selfcreateHeaderViewWithWidth:pageWidthdateText:dateTextname:self.user.real_namepdmSN:pdmSNpumpBaseSN:pumpBaseSNtransmitterSN:transmitterSN];
[self createFooterViewWithWidth:pageWidth height:(pageHeight - 35) name:self.myDelegate.user.real_name ? self.myDelegate.user.real_name : self.myDelegate.user.username pageNumber:(unsigned int)pageCount printTime:printTime];
UIGraphicsBeginImageContextWithOptions(self.tableView.contentSize, NO, 0.0);
[self.tableView.layer renderInContext:UIGraphicsGetCurrentContext()];
UIImage *image = UIGraphicsGetImageFromCurrentImageContext();
CGFloatscale = [UIScreenmainScreen].scale;
offsetY += contentHeight;
if(pageCount ==1) {
contentHeight =self.tableView.sectionHeaderHeight+31*self.tableView.rowHeight;
}elseif(pageCount ==2) {
contentHeight =32*self.tableView.rowHeight;
}elseif(pageCount ==3) {
contentHeight =30*self.tableView.rowHeight;
}
CGImageRefimageRef =CGImageCreateWithImageInRect(image.CGImage,CGRectMake(0, offsetY * scale, image.size.width* scale, contentHeight * scale));
image = [UIImageimageWithCGImage:imageRef];
CGImageRelease(imageRef);
UIGraphicsEndImageContext();
[imagedrawInRect:CGRectMake(CGRectGetMinX(self.tableView.frame), headerViewHight, image.size.width/ scale, image.size.height/ scale)];
}while(pageCount *30<self.daysCount);
UIGraphicsEndPDFContext();
self.tableViewHeightConstraint.constant= layoutConstraintConstant;
returnstorePath;
}
2.把UIView上面的内容生成PDF文件，代码如下：
#pragma mark- Create PDF
- (NSString *)createPDF {
if (self.contentView.subviews.lastObject == nil || self.contentView.subviews.lastObject.subviews.count == 0) {
returnnil;
}
if (![self.contentView.subviews.lastObject.subviews.lastObject isKindOfClass:[UIScrollView class]]) {
returnnil;
}
NSDate*printTime = [NSDatedate];
NSString*fileName = [NSStringstringWithFormat:@"%@_%@_%@.pdf",self.patientRealName,self.title, [self.dateHourMinuteFormatterstringFromDate:printTime]];
NSURL*storeURL = [selfbuildStoreURLForFileName:fileName];
NSString*storePath = storeURL.path;
NSDictionary*pdmSettings =self.pdmSettings;
NSString*createdTimeStr =@"";
if([pdmSettingsobjectForKey:@"CreatedTime"]) {
createdTimeStr = [self.dateTimeFormatterstringFromDate:[pdmSettingsobjectForKey:@"CreatedTime"]];
}
NSString*pdmSN =@"";
if([pdmSettingsobjectForKey:@"PDMSN"]) {
pdmSN = [AppDelegatetransformSerialString:[pdmSettingsobjectForKey:@"PDMSN"]];
}
NSString*pumpBaseSN =@"";
if([pdmSettingsobjectForKey:@"PumpBaseSN"]) {
pumpBaseSN = [AppDelegatetransformSerialString:[pdmSettingsobjectForKey:@"PumpBaseSN"]];
}
NSString*transmitterSN =@"";
if([pdmSettingsobjectForKey:@"TransmitterSN"]) {
transmitterSN = [AppDelegatetransformSerialString:[pdmSettingsobjectForKey:@"TransmitterSN"]];
}
[self hideContentController:self.currentViewController];
UIGraphicsBeginPDFContextToFile(storePath, CGRectZero, nil);
NSUIntegerpageCount =0;
for(inti =0; i <4; i++) {
pageCount ++;
UIViewController*printViewController;
switch(i) {
case1:
printViewController =self.bolusSettingsViewController;
break;
case2:
printViewController =self.sensorSettingsViewController;
break;
case3:
printViewController =self.utilitiesSettingsViewController;
break;

printViewController =self.basalSettingsViewController;
break;
}
[selfdisplayContentController:printViewController];
[printViewController.viewlayoutIfNeeded];
UIScrollView *scrollView = self.contentView.subviews.lastObject.subviews.lastObject;
CGFloatpageWidth = scrollView.contentSize.width;
CGFloatpageHeight = scrollView.contentSize.height+143.f;
UIGraphicsBeginPDFPageWithInfo(CGRectMake(0,0, pageWidth, pageHeight),nil);
NSString*dateText = [NSStringstringWithFormat:@"%@ %@", [self.segmentedtitleForSegmentAtIndex:i], createdTimeStr];
CGFloatheaderViewHight = [selfcreateHeaderViewWithWidth:pageWidthdateText:dateTextname:self.patientRealNamepdmSN:pdmSNpumpBaseSN:pumpBaseSNtransmitterSN:transmitterSN];
[self createFooterViewWithWidth:pageWidth height:(pageHeight - 35) name:self.myDelegate.user.real_name ? self.myDelegate.user.real_name : self.myDelegate.user.username pageNumber:(unsigned int)pageCount printTime:printTime];
for(UIView*viewinscrollView.subviews) {
if(![viewisKindOfClass:[UIImageViewclass]]) {
UIGraphicsBeginImageContextWithOptions(view.bounds.size, NO, 0.0);
[view.layer renderInContext:UIGraphicsGetCurrentContext()];
UIImage *image = UIGraphicsGetImageFromCurrentImageContext();
if(![viewisKindOfClass:[UILabelclass]] && ![viewisKindOfClass:[UITableViewclass]]) {
image = [selfadjustColor:image];
}
UIGraphicsEndImageContext();
[imagedrawInRect:CGRectMake(CGRectGetMinX(view.frame), CGRectGetMinY(view.frame) + headerViewHight, CGRectGetWidth(view.frame), CGRectGetHeight(view.frame))];
}
}
[selfhideContentController:printViewController];
