Mtnet self-use iOS network library open source

Mtnet self-use iOS network library Open source, for a long time, in a few arrivals shelves of the app running stable and reliable ~ deliberately open source out, interested students can look at Https://github.com/GangWang/MTNET


Mtnet
Mtnet is a very lightweight, powerful iOS HTTP network library that handles a large number of frequently initiated HTTP requests, and is good and stable in the number of arrivals apps that are already in use.

Other network libraries are easy to get started with, but it can be cumbersome to handle more dense and larger file downloads.

Using the download pool to manage all network downloads, you can set the number of simultaneous requests to be downloaded, abort and cancel for a single request, and provide two ways to receive data: Memory receive and disk receive.

Disk receive data will be small chunks of data to write to the disk, to avoid if the download file size caused by the memory crunch

Developers can inherit the Mtdownloadrecvdatafilesystem class, flexibly specify the storage path and store file name of the downloaded file, and provide a way for the file to cache and retrieve the cached file.

Mtnet is the MRC version

Declaring a download pool

@property (nonatomic, Strong) mtdownloaderhelper * downloadhelper;

...

Self.downloadhelper = [[Mtdownloaderhelper alloc] init];
Set the maximum number of tasks that can be performed at a download pool

[Self.downloadhelper Setmaxconcurrenttaskcount:5];
You can specify the same download timeout setting for all links in the download pool

[Self.downloadhelper settimeout:20];
Put a download request into the download pool

Mtdownloadrequest * request = [[Mtdownloadrequest alloc] init];
Mtdownloadobjectmodel * Downloadmdel = [[Mtdownloadobjectmodel alloc] init];
Downloadmdel.url = @ "http://www.baidu.com";
Request.downloadmodel = Downloadmdel;

Request.delegate = self;

[Self.downloadhelper Adddownloadrequest:request];
Cancels a download request so that the download request is removed from the download queue without starting the download. Abort the current download if it has started to open

[Self.downloadhelper CancelDownloadRequestByName:request.name];
Get download results using Mtdownloadrequestdelegate

-(void) Didtaskreceivedatafinish: (NSData *) Thedata Request: (mtdownloadrequest*) Request
{
NSLog (@ "Download OK");
}

-(void) taskdatadownloadfailed: (Nserror *) Error Request: (mtdownloadrequest*) Request
{
NSLog (@ "Download failed:%@", error);
}
Custom Receive Download rules

You can inherit mtdownloadrecvdatafilesystem to make the download rules yourself, and in this class are two methods of Processrecvalldatafinish and processrecvalldatafalied. Overrides can be customized to handle errors in the current data download or after successful operation

such as the download of data errors need to clean up the cache, after the successful download needs to extract files, compression, image scaling, etc.

#import "MTDownloadRecvData.h"

@interface Appimagedowloadrecv:mtdownloadrecvdatafilesystem

-(void) Setfilename: (NSString *) fileName;

@end



#import "AppImageDowloadRecv.h"
#import "MTPATH.H"
#import "MTFile.h"
#import "Nsstring+extension.h"
#import "McfDef.h"

@implementation APPIMAGEDOWLOADRECV

-(ID) init
{
self = [super init];
if (self)
{
Self.localcachedirpath = [Mtpath combine:kcache combinepath:@ "AppData"];
Static BOOL created = FALSE;
if (!created) {
created = TRUE;
[Mtpath CreateDirectory:self.localCacheDirPath Withattributes:nil];
}
}

return self;
}

-(void) Setfilename: (NSString *) fileName
{
if ([NSString Isnilorempty:filename])
{
Return
}

Self.name = FileName;
Self.localfullpath = [Mtpath Combine:self.localCacheDirPath combinepath:filename];
}

-(BOOL) bcached
{
return [Mtfile FileExistsAtPath:self.localFullPath];
}

-(NSData *) data
{
if ([Self bcached])
{
return [NSData DataWithContentsOfFile:self.localFullPath];
}

return nil;
}

Put a request for your own definition download rule to the download pool

Mtdownloadrequest * request = [[Mtdownloadrequest alloc] init];

Mtdownloadobjectmodel * Downloadmdel = [[Mtdownloadobjectmodel alloc] init];
Downloadmdel.url = @ "http://www.baidu.com";
Request.downloadmodel = Downloadmdel;

APPIMAGEDOWLOADRECV * RecvData = [[Appimagedowloadrecv alloc] init];
[RecvData setfilename:@ "filename"];
Request.recvdata = RecvData;

Request.delegate = self;

[Self.downloadhelper Adddownloadrequest:request];
