iOS拍照上传图片，拍竖图而获取到的是横图解决方案

创建UIImage分类方法：

- (UIImage *)normalizedImage  {
if (self.imageOrientation == UIImageOrientationUp) return self;

UIGraphicsBeginImageContextWithOptions(self.size, NO, self.scale);
[self drawInRect:(CGRect){0, 0, self.size}];
UIImage *normalizedImage = UIGraphicsGetImageFromCurrentImageContext();
UIGraphicsEndImageContext();
return normalizedImage;
}

拍照后获取到的图片调用一下方法normalizedImage即可解决！
