HQDownLoadTool

基于NSURLSession的大文件下载器,支持断点下载,下载进度等

#import <Foundation/Foundation.h>

typedef NS_ENUM(NSInteger, HQDownLoaderState) {
    /** 下载暂停 */
    HQDownLoaderStatePause,
    /** 正在下载 */
    HQDownLoaderStateDowning,
    /** 已经下载 */
    HQDownLoaderStateSuccess,
    /** 下载失败 */
    HQDownLoaderStateFailed
};

typedef void(^DownLoadStateChange)(HQDownLoaderState downLoaderState);
typedef void(^DownLoadMessage)(long long totalSize, NSString *downLoadedPath);
typedef void(^DownLoadPrograssChange)(float progress);
typedef void(^DownLoadSuccess)(NSString *downLoadedPath);
typedef void(^DownLoadFailed)(NSString *errorMsg);

用法

- (IBAction)downLoad:(id)sender {
    
    NSURL *url = [NSURL URLWithString:@"http://XXXXXXXXXXXXXXXX"];
    [self.downLoader downLoadWithURL:url messageBlock:^(long long totalSize, NSString *downLoadedPath) {
        
        NSLog(@"开始下载--%@--%lld",downLoadedPath,totalSize);
        
    } progress:^(float progress) {
        
        NSLog(@"下载中--%f",progress);
        
    } success:^(NSString *downLoadedPath) {
        
        NSLog(@"完成--%@",downLoadedPath);
        
    } failed:^(NSString *errorMsg) {
        
        NSLog(@"失败--%@",errorMsg);
        
    }];
}
