情景： 多选视频，然后打包成一个zip压缩包（里面有多个视频，一个json文件）
一、先生成本地的文件：
-(NSString *)getDocumentPath
{
NSFileManager *fileManager = [NSFileManager defaultManager];
NSString *dic = [NSHomeDirectory() stringByAppendingString:@"/Documents/ufile"];
NSString * fileName =[NSString stringWithFormat:@"ufile.json"];
BOOL isDic;
if(![fileManager fileExistsAtPath:dic isDirectory:&isDic]||(!isDic))
{
[fileManager createDirectoryAtPath:dic withIntermediateDirectories:YES attributes:nil error:nil];
}
NSString* filePath = [NSString stringWithFormat:@"%@/%@",dic,fileName];
if (![fileManager fileExistsAtPath:filePath]) {
[[NSFileManager defaultManager]createFileAtPath:filePath contents:nil attributes:nil];
}
return filePath;
}
二、生成json文件的时候的代码：
1、先自己生成个内容类似于son的NSMutableDictionary
2、将这个字典转换成NSData，写入到本地的文件中
NSData * jsonData =[NSJSONSerialization dataWithJSONObject:[self createDataDic] options:NSJSONWritingPrettyPrinted error:&parseError];
[jsonData writeToFile:jsonPath atomically:YES];三、文件压缩：
1、
#import "ZipArchive.h"
2、压缩方法：
-(void)zip{
BOOL isDir=NO;
NSFileManager *fileManager = [NSFileManager defaultManager];
NSString *mypath = NSSearchPathForDirectoriesInDomains(NSDocumentDirectory, NSUserDomainMask, YES)[0];
NSString *file = [NSString stringWithFormat:@"%@/%@",mypath,@"ufile"];
NSArray *subpaths = [fileManager subpathsAtPath:file];
// NSLog(@"subpaths %@",subpaths);
NSString *archivePath = [mypath stringByAppendingString:[NSString stringWithFormat:@"/%@.zip",@"ufile"]];
ZipArchive *archiver = [[ZipArchive alloc] init];
[archiver CreateZipFile2:archivePath];
// NSLog(@"ZIP archivePath的地址为： %@",archivePath);
for(NSString *path in subpaths)
{
NSString *longPath = [file stringByAppendingPathComponent:path];
if([fileManager fileExistsAtPath:longPath isDirectory:&isDir] && !isDir)
{
//注意newname的设置 也有可能是这样[NSString stringWithFormat:@"%@/%@",@"ufile",path]
[archiver addFileToZip:longPath newname:path];
}
}
//add kao 20130620
//注释后添加
[archiver CloseZipFile2];
}
特别要注意的是： newname的设置，有几种情况，正常情况下只需要直接将数组subpaths中的地址直接赋值就好。
四： 上传到服务器：
/** * 功能 AFNetWorking带进度指示文件上传 *
@param filePath 文件路径 */
-(void)uploadfile:(NSString *)filePath{
NSMutableString *addstring;
addstring=[NSMutableString stringWithFormat:@"http:///api/XXXXXX"];
[addstring insertString:[[NSUserDefaults standardUserDefaults] objectForKey:HTTPmyAPI] atIndex:7];
NSData *filedata=[NSData dataWithContentsOfFile:filePath];
AFHTTPRequestOperationManager *mymanager=[AFHTTPRequestOperationManager manager];
mymanager.requestSerializer = [AFJSONRequestSerializer serializer];
[GetSomething setManager:mymanager time:[GetSomething getTimeNow] value:nil];
[manager.requestSerializer setValue:@"application/octet-stream" forHTTPHeaderField:@"Content-Type"];
[manager POST:addstring parameters:nil constructingBodyWithBlock:^(id<AFMultipartFormData> formData){
[MBProgressHUD showMessage:nil];
[formData appendPartWithFileData:filedata name:@"ufile" fileName:@"ufile.zip" mimeType:@"application/octet-stream"];
} success:^(AFHTTPRequestOperation *operation, id responseObject){
[MBProgressHUD hideHUD];
dispatch_async(dispatch_get_main_queue(), ^{
MBProgressHUD * hud =[MBProgressHUD showHUDAddedTo:self.view animated:YES];
hud.mode = MBProgressHUDModeText;
hud.labelText = KSetString(@"local_uploadsuccess");
hud.removeFromSuperViewOnHide =YES;
[hud hide:YES afterDelay:0.7f];
});
[self deleteLocalZipFile];
}failure:^(AFHTTPRequestOperation *operation, NSError *error){
NSLog(@"上传失败");
NSLog(@"%@",error);
[MBProgressHUD hideHUD];
UIAlertView *alertView = [[UIAlertView alloc] initWithTitle:KSetString(@"local_uploadfailed") message:nil delegate:nil cancelButtonTitle:KSetString(@"local_know") otherButtonTitles:nil];
[alertView show];
[self deleteLocalZipFile];
}];
}
//删除本地的文件
-(void)deleteLocalZipFile
{
//完成要删除
[upLoadDataArray removeAllObjects];
[classSelectedArray removeAllObjects];
[self hide];
NSFileManager *fileManager = [NSFileManager defaultManager];
//移除文件夹
NSString *dic = [NSHomeDirectory() stringByAppendingString:@"/Documents/ufile"];
if ([fileManager fileExistsAtPath:dic]) {
// NSLog(@"移除文件夹 %@",dic);
[fileManager removeItemAtPath:dic error:nil];
}
//移除zip包
NSString *mypath = NSSearchPathForDirectoriesInDomains(NSDocumentDirectory, NSUserDomainMask, YES)[0];
NSString *archivePath = [mypath stringByAppendingString:[NSString stringWithFormat:@"/%@.zip",@"ufile"]];
if ([fileManager fileExistsAtPath:archivePath]) {
[fileManager removeItemAtPath:archivePath error:nil];
}
}
这边的上传的参数为nil，具体的设置每个人都不同，所以你们自己解决就好了~~
