因客户要求,在APP中的图片都是从七牛的服务器中获取的,所以所有的上传图片也要上传到七牛上.又因为服务器不做批量上传的接口,所以只能自己写了;七牛的sdk只提供单张图片的上传,坑人!不多说了,上代码

使用方法:
单张图片:
[UploadImageTool uploadImage:self.holdImage progress:nil success:^(NSString*url) {
NSLog(@"qin niu --%@",url);
}failure:^{
NSLog(@" --->> error:");
}];
多张图片:
[UploadImageTool uploadImages:self.imgArray progress:^(CGFloat progress) {
NSLog(@"qin niu --%f",progress);
}success:^(NSArray*urlArr) {
NSLog(@"qin niu --%@",urlArr);
}failure:^{
NSLog(@" --->> error:");
}];
