SZDownloader是一个用于下载文件的小型库。您可以使用Block或Delegate下载文件。如果您正在使用TableView，您应该使用Delegate而不是Block。
下载SZDownloader.h和SZDownloader.m并添加到你的项目。
SZDownloader * downloader = [[SZDownloader alloc] initWithURL：[NSURL URLWithString：@“http://myfile.com/file.jpg”] timeout：60];
[downloader startWithDownloading：（float progress，NSInteger percentage）{
//进度条进度
//下载百分比的百分比
} onFinished :( NSData * fileData，NSString * fileName）{
//使用NSData编写文件或图像
} onFail（NSError * error）{
//失败
}];
遵循SZDownloaderDelegate协议
SZDownloader * downloader = [[SZDownloader alloc] initWithURL：[NSURL URLWithString：@“http://myfile.com/file.jpg”] timeout：60];
[downloader startWithDelegate：self];//委托方法是必需的
- （void）SGDownloadProgress：（float）progress百分比：（NSInteger）percent;
- （void）SGDownloadFinished :( NSData *）fileData;
- （void）SGDownloadFail：（NSError *）error;
允许1-5个并发下载1个文件（如下载管理器）
[objc] view plain copy 在CODE上查看代码片派生到我的代码片
-(void)download
{
_requestStringURL=kCloudURL;
NSURL *requestURL=[NSURL URLWithString:_requestStringURL];
SZDownloader *downloader=[[SZDownloader alloc] initWithURL:requestURL timeout:6.0];
[downloader startWithDownloading:^(float progressValue, NSInteger percentage)
{
NSLog(@"progressValue=%f,percentage=%ld",progressValue,percentage);
} onFinished:^(NSData *fileData)
{
NSDictionary *jsonDict=[NSJSONSerialization JSONObjectWithData:fileData options:NSJSONReadingMutableLeaves error:nil];
NSLog(@"jsonDict=%@",jsonDict);
[downloader cancel];
}
onFail:^(NSError *error)
{
NSLog(@"auth error=%@",error);
[downloader cancel];
}];
}
- 允许暂停和恢复
- 允许下载与进度
最后，如果您觉得SZDownloader好，请点个star,或者加入进来维护它。O(∩_∩)O谢谢！
SZDownloader is a small library for downloading file. It supported
Block Delegate ARC You can use Block or Delegate for downloading the file. If you are using with TableView, you should use Delegate instead of Block.
Put
SZDownloader.h SZDownloader.m to your project.
SZDownloader *downloader = [[SZDownloader alloc] initWithURL:[NSURL URLWithString:@"http://myfile.com/file.jpg"] timeout:60];
[downloader startWithDownloading:(float progress,NSInteger percentage) {
//progress for progress bar
//percentage for download percentage
} onFinished:(NSData* fileData,NSString* fileName){
//use NSData to write a file or image
}onFail (NSError* error){
//on fail
}];
@interface progressCell : UITableViewCell in .m file
SZDownloader *downloader = [[SZDownloader alloc] initWithURL:[NSURL URLWithString:@"http://myfile.com/file.jpg"] timeout:60];
[downloader startWithDelegate:self];
Delegate Methods are required
-(void)SGDownloadProgress:(float)progress Percentage:(NSInteger)percentage;
-(void)SGDownloadFinished:(NSData*)fileData;
-(void)SGDownloadFail:(NSError*)error;
allow 1-5 concurrent download for 1 file (like download manager)
-(void)download
{
_requestStringURL=kCloudURL;
NSURL *requestURL=[NSURL URLWithString:_requestStringURL];
SZDownloader *downloader=[[SZDownloader alloc] initWithURL:requestURL timeout:6.0];
[downloader startWithDownloading:^(float progressValue, NSInteger percentage)
{
NSLog(@"progressValue=%f,percentage=%ld",progressValue,percentage);
} onFinished:^(NSData *fileData)
{
NSDictionary *jsonDict=[NSJSONSerialization JSONObjectWithData:fileData options:NSJSONReadingMutableLeaves error:nil];
NSLog(@"jsonDict=%@",jsonDict);
[downloader cancel];
}
onFail:^(NSError *error)
{
NSLog(@"auth error=%@",error);
[downloader cancel];
}];
}
-
Allow Pause and Resume
-
Allow Download with Progress
Finally,if you think SZDownloader is good,please star it or join us to maintain it.thanks you.
