最近使用阿里云的oss 上传文件遇到的问题
解决方式 外层加了队列，本文主要写线程和信号量 持续更新
dispatch_async(dispatch_get_global_queue(0, 0), ^{
// 分块上传
[upload multipartUpload:videoPath objectKey:objectKeyName];
if([[self viewController] respondsToSelector:@selector(creatBackViewForUpdatePress)]){
[[self viewController] performSelector:@selector(creatBackViewForUpdatePress) withObject:nil];
}
});
信号量 网络请求的顺序 ：
先上代码
-(void)loadData{
WS(wSelf)
