iOS 上传多张图片到七牛空间

1.上传图片到七牛会需要一个上传凭证，该上传token公司的后台会提供，我们只需要用根据后台提供的接口，请求到我们需要的上传token。然后根据七牛提供的方法QNUploadManager进行图片上传。上传成功会获取到图片的key

2.实现思路：从相册选择图片后，把图片的data存储到一个的数组中，然后用for循环遍历获取到每张图片的data   代码：

-(void)getTokenFromQN{

 inti =0;

for(NSData*data1in_textView.allDatats) {

//生成图片的名字key

NSString*key = [NSStringstringWithFormat:@"%@-%d",[self imageKey],i];

NSString* userId = [[NSUserDefaultsstandardUserDefaults]objectForKey:USERID];

intuid = [userId intValue];

NSString*token = [[NSUserDefaults standardUserDefaults]objectForKey:TOKEN];

NSMutableDictionary*params = [[NSMutableDictionaryalloc]init];

params[@"uid"]=@(uid);

params[@"token"]=token;

[[ToolNetsharedToolNet]POST:UPTOKEN_URLparameters:paramssuccess:^(id_NonnullresponseObject) {

NSDictionary*data = [response ObjectobjectForKey:@"data"];

self.qnToken= [dataobject ForKey:@"token"];

if(![_textView.videoData containsObject:data1]) {

[self uploadImageToQNFilePath:data1key:keytoken:_qnToken];

}else{

[self uploadImageToQNFilePath:data1key:_videoKeytoken:_qnToken];

}

DLog(@"===%@",_qnToken);

}failure:^(NSError*_Nonnullerror) {

}];

i++;

 }   

3.根据七牛提供的方法上传图片

-(void)uploadImageToQNFilePath:(NSData*)data key:(NSString*)key token:(NSString*)token{

QNUploadManager*upManager = [[QNUploadManager alloc]init];

QNUploadOption*opt = [[QNUploadOption alloc]initWithMime:nil

progressHandler:^(NSString*key,float percent)//上传进度

{

self.percentFloat= percent;

DLog(@"**%.2f",percent);

}params:@{@"x:foo":@"fooval"}checkCrc:YEScancellationSignal:nil];

[upManagerputData:datakey:keytoken:tokencomplete:               ^(QNResponseInfo*info,NSString*key,NSDictionary*resp) {

if(!info.error)

{

[_dataArr addObject:key];//存储图片名称的key,上传七牛需要用到

DLog(@"dataArr=%@",_dataArr);

if(_textView.imageArray.count==_dataArr.count) {

DLog(@"dataArr=%@",_dataArr);

[self upALLImage];

[WSProgressHUD showImage:nilstatus:@"上传成功"];

}

}else{

NSLog(@"****%@",info.error);

}

}option:opt];

self.timer= [NSTimerscheduledTimerWithTimeInterval:1target:selfselector:@selector(getPercente)userInfo:nilrepeats:YES];

}

//根据时间戳标示图片的key,防止图片上传重复或者失败

- (NSString*)imageKey {

//根据当前系统时间生成图片名称

NSDate*date = [NSDatedate];

longtime=(long)[datetimeIntervalSince1970];//获取时间戳

return[NSStringstringWithFormat:@"%ld",time];

}
