JSON解析步骤:
1.获取json文件路径
NSString*path = [[NSBundle mainBundle] pathForResource:@"Teacher"ofType:@"json"];
2.读取文件中的data
NSData *data = [NSData dataWithContentsOfFile:path];
3.把data转化为可变数组或者可变字典 是字典还是数组要看json最外层数据是什么.NSJSONSerialization是重点
NSError *error = nil; NSMutableArray*dataArray = [NSJSONSerialization JSONObjectWithData:data options:NSJSONReadingMutableContainerserror:&error];
- (void)parserDidStartDocument:(NSXMLParser *)parser
{
// 初始化数组
self.dataArray = [NSMutableArray array];
NSLog(@"已经开始分析文件");
}
- (void)parser:(NSXMLParser *)parser didStartElement:(NSString *)elementName namespaceURI:(NSString *)namespaceURI qualifiedName:(NSString *)qName attributes:(NSDictionary *)attributeDict
{
// 初始化model
if ([elementName isEqualToString:@"Student"]) {
self.model = [[StudentModel alloc] init];
}
NSLog(@"<%@>", elementName);
// NSLog(@"开始遇到节点");
}
- (void)parser:(NSXMLParser *)parser foundCharacters:(NSString *)string
{
// 保存字符串
self.string = string;
//NSLog(@"发现字符");
NSLog(@"%@", string);
}
- (void)parser:(NSXMLParser *)parser didEndElement:(NSString *)elementName namespaceURI:(NSString *)namespaceURI qualifiedName:(NSString *)qName
{
// 给model赋值
if ([elementName isEqualToString:@"name"]) {
self.model.name = self.string;
} else if ([elementName isEqualToString:@"gender"]) {
self.model.gender = self.string;
} else if ([elementName isEqualToString:@"age"]) {
self.model.age = self.string;
} else if ([elementName isEqualToString:@"motto"]) {
self.model.motto = self.string;
} else if ([elementName isEqual;ldghToString:@"Student"]) {
// 节点名字等于Student的时候一个model就赋值完成了 可以装进数组中
[self.dataArray addObject:self.model];
[_model release];
}
NSLog(@"遇到结束节点触发");
NSLog(@"</%@>", elementName);
}
- (void)parserDidEndDocument:(NSXMLParser *)parser
{
NSLog(@"%@", self.dataArray);
NSLog(@"已经结束分析文件");
}
现在一般多使用json解析.原文：http://www.cnblogs.com/pp123/p/4820478.html
