我正在尝试解析多级Xml文件，并将xml内容插入Sqldatabase。
我正在使用这个概念。
1 - 我正在创建定义xml标记的类，并将这些标记值初始化为@“null”字符串值。 像这样
@implementation lifeline_detail
@synthesize lifeline_title,lifeline_identifier,created_date,lifeline_image,lifeline_modifienddate;
-(void) lifeline_deatiail_values
{
lifeline_title=@"null";
lifeline_identifier=@"null";
created_date=@"null";
lifeline_image=@"null";
lifeline_modifienddate=@"null";
}
-(void) lifeline_title : (NSString *) xml_value
{lifeline_title=xml_value;
}
-(void) lifeline_identifier : (NSString *) xml_value
{
lifeline_identifier=xml_value;
}
-(void) created_date : (NSString *) xml_value
{
created_date=xml_value;
}
-(void) lifeline_modifienddate : (NSString *) xml_value
{
lifeline_modifienddate=xml_value;
}
-(void) lifeline_image : (NSString *) xml_value
{
lifeline_image=xml_value;
}
-(void) dealloc
{
[lifeline_image release];
[lifeline_title release];
[created_date release];
[lifeline_modifienddate release];
[lifeline_identifier release];
[super dealloc];
}
@end
2-我将此类导入到我的另一个用于解析xml文件的类中，并将数据插入到sqlite数据库中。
那个电话就是那个

当我采用这种类型的概念时，我是对还是错。
因为我的应用程序难以理解此错误
- [CFString release]：发送到解除分配的实例0x11815530的消息
我真的找不到我错在哪里。
请帮助我。
过去20天我遇到了这个问题。
请帮帮我
答案 0 :(得分：1)
班级名称以大写字母开头
方法名称为camelCasedAndDoNotContainUnderscores
尝试“构建和分析”;修复它识别的任何问题
retainCount无用。不要打电话。
setter方法以单词set开头，不包含下划线; setMyName:，例如
您的所有setter方法都未正确实现;直接设置值而不保留任何内容。正如迈克所说，请阅读memory management documentation guide。
parserDidStartDocument:的实施没有意义;如果设置了myDatabasePath（重命名为遵循约定），它将成为一个悬空指针并崩溃。
由于不知道Objective-C是nil-eats-message语言，因此存在大量不必要的代码。我也建议你也阅读Objective-C concepts document。
