遵守代理<UIImagePickerControllerDelegate>
1、弹窗
UIAlertController *alertController = [UIAlertController alertControllerWithTitle:@"请选择" message:nil preferredStyle:UIAlertControllerStyleActionSheet];
UIAlertAction *cancelAction = [UIAlertAction actionWithTitle:@"取消" style:UIAlertActionStyleCancel handler:nil];
UIAlertAction *CameraAction = [UIAlertAction actionWithTitle:@"相机" style:UIAlertActionStyleDefault handler:^(UIAlertAction * _Nonnull action) {
[weakself persentImagePicker:1];
}];
UIAlertAction *AlbumAction = [UIAlertAction actionWithTitle:@"相册" style:UIAlertActionStyleDefault handler:^(UIAlertAction * _Nonnull action) {
[weakself persentImagePicker:2];
}];
[alertController addAction:CameraAction];
[alertController addAction:AlbumAction];
[alertController addAction:cancelAction];
[weakself presentViewController:alertController animated:YES completion:nil];
2、 获取图片、照片
//调用本地相册
- (void)persentImagePicker:(int)type{
if (!_imagePickerG) {
///初始化相机
_imagePickerG = [[UIImagePickerController alloc]init];
///代理
_imagePickerG.delegate = self;
}
if (type == 1) {//相机
_imagePickerG.sourceType = UIImagePickerControllerSourceTypeCamera;
_imagePickerG.allowsEditing = YES;
[self.navigationController presentViewController:_imagePickerG animated:YES completion:nil];
}else if (type == 2)//相册
{
_imagePickerG.sourceType = UIImagePickerControllerSourceTypePhotoLibrary;
_imagePickerG.allowsEditing = YES;
[self.navigationController presentViewController:_imagePickerG animated:YES completion:nil];
}
}
///取消选择图片（拍照）
- (void)imagePickerControllerDidCancel:(UIImagePickerController *)picker{
[picker dismissViewControllerAnimated:YES completion:nil];
}
///选择图片完成（从相册或者拍照完成）
- (void)imagePickerController:(UIImagePickerController *)picker didFinishPickingMediaWithInfo:(NSDictionary<NSString *,id> *)info{
//UIImage *image = [info objectForKey:UIImagePickerControllerOriginalImage];///原图
//获取修剪后的图片
UIImage *imageUp = [info objectForKey:UIImagePickerControllerEditedImage];
[self UpPic:imageUp];
[picker dismissViewControllerAnimated:YES completion:nil];
}
/**
///选择图片完成（从相册或者拍照完成）
- (void)imagePickerController:(UIImagePickerController *)picker didFinishPickingMediaWithInfo:(NSDictionary<NSString *,id> *)info{
UIImage *image = [info objectForKey:UIImagePickerControllerOriginalImage];///原图
//获取修剪后的图片
//UIImage *imageUp = [info objectForKey:UIImagePickerControllerEditedImage];
CGSize newSize = CGSizeMake(image.size.width*0.5, image.size.height*0.5);
UIImage *tempimage = [self reSizeImage:image toSize:newSize];
NSData *data = UIImageJPEGRepresentation(tempimage, 1);
if (data.length/2014>=1000) {
newSize = CGSizeMake(tempimage.size.width*0.7, tempimage.size.height*0.7);
tempimage = [self reSizeImage:image toSize:newSize];
data = UIImageJPEGRepresentation(tempimage, 1);
}
[self SendBaiDuPress:tempimage];
self.wordImageView.image = tempimage;
[picker dismissViewControllerAnimated:YES completion:nil];
}
// 调整图片大小（这里是缩小图片）
- (UIImage *)reSizeImage:(UIImage *)image toSize:(CGSize)reSize
{
UIGraphicsBeginImageContext(CGSizeMake(reSize.width, reSize.height));
[image drawInRect:CGRectMake(0, 0, reSize.width, reSize.height)];
UIImage *reSizeImage = UIGraphicsGetImageFromCurrentImageContext();
UIGraphicsEndImageContext();
return reSizeImage;
}
*/
///保存图片到本地相册
-(void)imageTopicSave:(UIImage *)image{
UIImageWriteToSavedPhotosAlbum(image, self, @selector(image: didFinishSavingWithError: contextInfo:), nil);
}
- (void)image:(UIImage *)image didFinishSavingWithError:(NSError *)error contextInfo:(void *)contextInfo{
if (error == nil) {
}
else{
///图片未能保存到本地
}
}
3、上传图片
-(void)UpPic:(UIImage *)img
{
NSString *user_uuid = [[NSUserDefaults standardUserDefaults] objectForKey:@"user_uuid"];
if(user_uuid == nil)
{
LoginViewCTRL *loginViewCTRL = [[LoginViewCTRL alloc] init];
loginViewCTRL.loginVieCTRLBlock = ^{
};
[self.navigationController pushViewController:loginViewCTRL animated:YES];
}else
{
NSString *postUrl=[NSString stringWithFormat:@"%@%@%@",ServerOtherUrl,ProjectName,@"/user/updatePicture.do"];
NSDictionary *parameters=@{@"user_uuid":user_uuid
};
[MBProgressHUD showHUDAddedTo:self.view animated:YES];
NSData *imageData = UIImageJPEGRepresentation(img, 0.6);//image为要上传的图片(UIImage)
AFHTTPSessionManager *manager = [AFHTTPSessionManager manager];
manager.responseSerializer = [AFHTTPResponseSerializer serializer];
[manager POST:postUrl parameters:parameters constructingBodyWithBlock:^(id<AFMultipartFormData> _Nonnull formData) {
//
NSDateFormatter *formatter = [[NSDateFormatter alloc] init];
formatter.dateFormat = @"yyyyMMddHHmmss";
NSString *fileName = [NSString stringWithFormat:@"%@.png",[formatter stringFromDate:[NSDate date]]];
//二进制文件，接口key值，文件路径，图片格式
if (self.changePicType == 1)
{
[formData appendPartWithFileData:imageData name:@"head_img" fileName:fileName mimeType:@"image/jpg/png/jpeg"];
}else if (self.changePicType == 2)
{
[formData appendPartWithFileData:imageData name:@"cover_img" fileName:fileName mimeType:@"image/jpg/png/jpeg"];
}
} progress:^(NSProgress * _Nonnull uploadProgress) {
} success:^(NSURLSessionDataTask * _Nonnull task, id _Nullable responseObject) {
//
[MBProgressHUD hideHUDForView:self.view animated:YES];
NSLog(@"%@",task.currentRequest.URL);
[self GainUserInfo];
} failure:^(NSURLSessionDataTask * _Nullable task, NSError * _Nonnull error) {
//
[MBProgressHUD hideHUDForView:self.view animated:YES];
}];
}
}
注意：使用AFNetworking的方法：上传图片
//压缩图片
NSData *imageData = UIImageJPEGRepresentation(image,0);
//沙盒，准备保存的图片地址和图片名称
NSDateFormatter *formatter=[[NSDateFormatter alloc]init];
formatter.dateFormat=@"yyyyMMddHHmmss";
NSString *str=[formatter stringFromDate:[NSDate date]];
NSString *fullPath = [[NSHomeDirectory() stringByAppendingPathComponent:@"Documents"] stringByAppendingPathComponent:[NSString stringWithFormat:@"%@.jpeg",str]];
//将图片写入文件中
[imageData writeToFile:fullPath atomically:NO];
//通过路径获取到保存的图片，可以在主界面上的image进行预览
UIImage *saveImage = [[UIImage alloc]initWithContentsOfFile:fullPath];
AFHTTPSessionManager *manager = [AFHTTPSessionManager manager];
manager.requestSerializer.timeoutInterval = 20;
manager.responseSerializer.acceptableContentTypes = [NSSet setWithObjects:@"text/plain", @"multipart/form-data", @"application/json", @"text/html", @"image/jpeg", @"image/png", @"application/octet-stream", @"text/json", nil];
gron_User;
gron_self;
[manager.requestSerializer setValue:gron_Token forHTTPHeaderField:gron_AFNKEY];
NSMutableDictionary *dict = [NSMutableDictionary dictionary];
[dict setObject:@"1" forKey:@"flagFace"];
[dict setObject:@"1" forKey:@"zipFlag"];
[dict setObject:fullPath forKey:@"file"];
NSString *url = @"https://xxx.com";
MBProgressHUD *hub = [MBProgressHUD showHUDAddedTo:self.view animated:YES];
gron_hub;
[manager POST:url parameters:dict constructingBodyWithBlock:^(id<AFMultipartFormData> _Nonnull formData) {
/* 该方法参数
appendPartWithFileData：要上传的照片二进制流
name：对应后台要上传接口的参数名
fileName：要保存的文件名
mimeType：要保存到服务器的文件类型
*/
[formData appendPartWithFileData:imageData name:@"file" fileName:fullPath mimeType:@"image/jpg"];
} progress:^(NSProgress * _Nonnull uploadProgress) {
} success:^(NSURLSessionDataTask * _Nonnull task, id _Nullable responseObject) {
[hub hideAnimated:YES];
DSLog(@"上传成功");
} failure:^(NSURLSessionDataTask * _Nullable task, NSError * _Nonnull error) {
[hub hideAnimated:YES];
DSLog(@"上传失败");
}];
