用NSURLSession和NSURLConnection获取文件的MIMEType，nsurlNSURLSession和NSURLConnection都是苹果自带的用于网络请求的类，NSURLSession是iOS 7.0之后推出的用于替代NSURLConnection的。下面分享一下这两个类获取文件MIMEType的方法。
1 #pragma mark 获取文件的mimeType
2 // NSURLSession版
3 - (void)getMIMEType {
// 用NSBundle获取工程中文件路径
NSString *filePath = [[NSBundle mainBundle] pathForResource:@"a" ofType:@"png"];
// 创建NSURL对象
NSURL *fileUrl = [NSURL fileURLWithPath:filePath];
// 创建请求
NSURLRequest *request = [NSURLRequest requestWithURL:fileUrl];
// 创建NSURLSession的单例
NSURLSession *session = [NSURLSession sharedSession];
// 创建一个dataTask请求数据
NSURLSessionDataTask *dataTask = [session dataTaskWithRequest:request completionHandler:^(NSData *data, NSURLResponse *response, NSError *error) {
// response.MIMEType就是文件的MIMEType
NSLog(@"%@", response.MIMEType);
// session的任务默认是挂起的，需要手动启用
[dataTask resume];
20 // NSURLConnection版
21 - (void)getMIMEType1 {
// 用NSBundle获取工程中文件路径
NSString *filePath = [[NSBundle mainBundle] pathForResource:@"a" ofType:@"png"];
// 创建NSURL对象
NSURL *fileUrl = [NSURL fileURLWithPath:filePath];
// 创建请求
NSURLRequest *request = [NSURLRequest requestWithURL:fileUrl];
NSURLResponse *response =
// 同步请求
[NSURLConnection sendSynchronousRequest:request returningResponse:&response error:nil];
// response.MIMEType就是文件的MIMEType
NSLog(@"%@", response.MIMEType);

MIME 参考手册
MIME (Multipurpose Internet Mail Extensions) 是描述消息内容类型的因特网标准。
MIME 消息能包含文本、图像、音频、视频以及其他应用程序专用的数据。
官方的 MIME 信息是由 Internet Engineering Task Force (IETF) 在下面的文档中提供的：
Standard for
ARPA Internet text messages
MIME Part 1: Format of Internet Message Bodies
MIME Part 2: Media Types
MIME Part 3: Header Extensions for Non-ASCII Text
MIME Part 4: Registration Procedures
MIME Part 5: Conformance Criteria and Examples
不同的应用程序支持不同的 MIME 类型。
下面的参考手册是由 Microsoft Internet Information Server version 5 所支持的 MIME 类型列表。
