我有一种方法可以将输入的客户数据保存在调用 createPDFFile 方法的表单中。我已经创建了 PDF 文件，并且目前在其中有一些填充字符串，以便我可以布置 PDF 文件，我现在想从 NSTextField 中获取 stringValue，然后将其附加到包含磁贴的字符串中，例如：@ “名称：”从 NSTextField 中附加 stringValue。我可以让第一个项目工作，因为我将 IBOutput 更改为保留，并且对第一个项目有效，但对第二个项目无效，依此类推。我收到 BAD_AXCESS 错误，但仅在方法完成时。
这是 PDF 绘制方法的开始：
-(void)drawPDFCustomerInfoWithContext:(CGContextRef)currentContext andWithPageSize:(CGSize)pageSize andCustomerObject:(Customer *)currentCustomer{
CTFontRef font = CTFontCreateWithName(CFSTR("Arial"), 12, NULL);
CFRange currentRange = CFRangeMake(0, 0);
CGContextSetTextMatrix(currentContext, CGAffineTransformIdentity);
NSString *customerName = [[[@"Name: " stringByAppendingString:self.firstNameTextField.stringValue] stringByAppendingString:@" "] stringByAppendingString:self.lastNameTextField.stringValue];
NSString *customerAddress = @"Address: ";
NSString *customerCity = @"City: ";
NSString *customerState = @"State: ";
NSString *customerZipcode = @"Zipcode: ";
NSString *customerPhone = @"Phone: ";
NSString *customerEmail = @"Email: ";
CFStringRef customerNameStringRef = (__bridge CFStringRef)customerName;
CFStringRef customerAddressStringRef = (__bridge CFStringRef)customerAddress;
CFStringRef customerCityStringRef = (__bridge CFStringRef)customerCity;
CFStringRef customerStateStringRef = (__bridge CFStringRef)customerState;
CFStringRef customerZipCodeStringRef = (__bridge CFStringRef)customerZipcode;
CFStringRef customerPhoneStringRef = (__bridge CFStringRef)customerPhone;
CFStringRef customerEmailStringRef = (__bridge CFStringRef)customerEmail;
这是保存方法：
- (IBAction)sendEstimateToCustomer:(id)sender {
float tempFloat = [[self.estimateNumberLabel stringValue]floatValue];
self.customerDataArray = [[NSMutableArray alloc]initWithArray:[self createCustomerDataArrayWithFirstName:self.firstNameTextField.stringValue andLastName:self.lastNameTextField.stringValue andAddress:self.customerAddress.stringValue andCity:self.customerCity.stringValue andState:self.customersState.stringValue andZipCode:self.customerZipcode.stringValue andPhone:self.customerPhone.stringValue andEmail:self.customerEmail.stringValue andEstimateNumber:tempFloat]];
self.customer = [[Customer alloc]initWithCustomerDataArray:self.customerDataArray];
[self createEstimatePDF];
这是 createEstimatePDF 方法
-(void)createEstimatePDF{
NSLog(@"create Estimate Method Fired");
CGContextRef pdfContext;
CFURLRef url;
url = [self createPDFPath];
CFMutableDictionaryRef myDictionary = NULL;
myDictionary = CFDictionaryCreateMutable(NULL, 0, &kCFTypeDictionaryKeyCallBacks, &kCFTypeDictionaryValueCallBacks);
CFDictionarySetValue(myDictionary, kCGPDFContextTitle, CFSTR("My PDF File"));
CFDictionarySetValue(myDictionary, kCGPDFContextCreator, CFSTR("Ben"));
pdfContext = CGPDFContextCreateWithURL(url,NULL, myDictionary);
CFRelease(url);
CGPDFContextBeginPage(pdfContext,myDictionary);
CGSize pageSize = CGSizeMake(612, 792);
[self drawPDFJobDescriptionTableWithContext:pdfContext andWithPageSize:pageSize];
[self drawPDFContractualTextWithContext:pdfContext andPageSize:pageSize];
[self drawPDFCustomerInfoWithContext:pdfContext andWithPageSize:pageSize andCustomerObject:self.customer];
[self drawPDFEstimateNumberWithContext:pdfContext andWithPageSize:pageSize];
[self drawPDFJobTableHeadersWithContext:pdfContext andPageSize:pageSize];
[self drawPDFBorderWithContext:pdfContext andWithPageSize:pageSize];
[self drawPDFHeaderWithContext:pdfContext andWithPageSize:pageSize];
[self drawPDFLegalStatementWith:pdfContext andPageSize:pageSize];
[self drawPDFSignatureAndDateWith:pdfContext andPageSize:pageSize];
[self drawPDFSignLinesWithContext:pdfContext andPageSize:pageSize];
CFRelease(myDictionary);
CGPDFContextEndPage(pdfContext);
我认为有些东西正在被释放，但我不知道在哪里。我观察了变量并逐步检查，它们一直显示值，然后繁荣，击中该方法的最后一个右括号，然后显示 BAD_ACCESS 错误。我不明白的是，这行得通，
NSString *customerName = [[[@"Name: " stringByAppendingString:self.firstNameTextField.stringValue] stringByAppendingString:@" "] stringByAppendingString:self.lastNameTextField.stringValue];
我也尝试复制这些值以通过方法以及传递的客户对象传递数据。
如果需要更多信息，我可以提供。所有的 NSTextfields 都保留
