ios15使用NSXMLParser解析XML

ios15解析XML

今天我们使用NSXMLParser这个类解析XML。
解析的类必须遵守NSXMLParserDelegate代理。

- (void)viewDidLoad {
    [super viewDidLoad];
    NSString *path = [[NSBundle mainBundle] pathForResource:@"111.xml" ofType:nil];
    NSData *data = [NSData dataWithContentsOfFile:path];
    NSXMLParser *parse =  [[NSXMLParser alloc] initWithData:data];
    parse.delegate = self;
    [parse parse];
}

设置parse.delegate = self;

- (void)parserDidStartDocument:(NSXMLParser *)parser{}
- (void)parserDidEndDocument:(NSXMLParser *)parser{}
- (void)parser:(NSXMLParser *)parser didStartElement:(NSString *)elementName namespaceURI:(NSString *)namespaceURI qualifiedName:(NSString *)qName attributes:(NSDictionary<NSString *,NSString *> *)attributeDict{
    if([@"videos" isEqualToString:elementName]){
        self.videos = [NSMutableArray array];
    }else if([@"video" isEqualToString:elementName]){
       // HMVideo *v1 = [HMVideo videmoWithDict:attributeDict];
      //  [self.videos addObject:v1];
        NSLog(@"123");
        UIButton *btn = [[UIButton alloc] init];
        [self.videos addObject:btn];
    }
}
- (void)parser:(NSXMLParser *)parser didEndElement:(NSString *)elementName namespaceURI:(NSString *)namespaceURI qualifiedName:(NSString *)qName{}

成员变量:@property(nonatomic,strong)NSMutableArray *videos;

touchBegin

- (void)touchesBegan:(NSSet<UITouch *> *)touches withEvent:(UIEvent *)event{
    NSLog(@"%ld",self.videos.count);
}
