ios利用 AFN 上传相册或者拍照图片

2024-02-18 11:08:03 47

由于项目中多处需要上传图片，我们可以自定义上传图片请求，自定义调取相册及拍照，方便多处使用时调用。

主要步骤：

1.第一步：请求上传你选取的相册图片或者拍照图片（经过压缩处理）

2.第二步：获取到第一步图片url上传给服务器

3.第三步：回显图片（当然进入该界面时先判断是否有图片，无图则展示占位图片，否则就回显图片）

废话不多说，直接上代码：

1）封装的上传图片的网络请求(图片压缩)QTXUploadImage文件

//利用afn上传一张图片
#import

@interfaceQTXUploadImage:NSObject

//上传图片的网络请求(图片压缩)
+(void)post:(NSString*)urlimage:(UIImage*)imagename:(NSString*)namesuccess:(void(^)(idjson))successfailure:(void(^)(NSError*error))failure;

@end

#import"QTXUploadImage.h"
#import"AFNetworking.h"
#import"QTXAccount.h"
#import"QTXAccountTool.h"

@implementationQTXUploadImage

/**
*上传图片的网络请求(图片压缩)
*
*@paramurl上传图片的网络请求地址
*@paramname和后台包名一致
*
*/
+(void)post:(NSString*)urlimage:(UIImage*)imagename:(NSString*)namesuccess:(void(^)(idjson))successfailure:(void(^)(NSError*error))failure{

//1.创建网络管理者
AFHTTPSessionManager*manager=[AFHTTPSessionManagermanager];

//2.拼接请求参数url也可在具体控制器请求里传入
NSDictionary*dict=@{@"userId":[QTXAccountToolaccount].userId};

//3.发送请求
[managerPOST:urlparameters:dictconstructingBodyWithBlock:
^void(idformData){

NSData*imageData=UIImageJPEGRepresentation(image,0.5);//进行图片压缩

//使用日期生成图片名称
NSDateFormatter*formatter=[[NSDateFormatteralloc]init];
formatter.dateFormat=@"yyyyMMddHHmmss";
NSString*fileName=[NSStringstringWithFormat:@"%@.png",[formatterstringFromDate:[NSDatedate]]];
//任意的二进制数据MIMETypeapplication/octet-stream
[formDataappendPartWithFileData:imageDataname:namefileName:fileNamemimeType:@"image/png"];

}success:^void(NSURLSessionDataTask*task,idresponseObject){

if(success){
success(responseObject);
}

}failure:^void(NSURLSessionDataTask*task,NSError*error){

if(failure){
failure(error);
}
}];
}
@end

2）封装的拍照/从相册选择QTXImagePicker文件

//拍照/从相册选择
#import

typedefvoid(^QTXImagePickerFinishAction)(UIImage*image);

@interfaceQTXImagePicker:NSObject

/**
@paramviewController用于presentUIImagePickerController对象
@paramallowsEditing是否允许用户编辑图像
*/
+(void)showImagePickerFromViewController:(UIViewController*)viewController
allowsEditing:(BOOL)allowsEditing
finishAction:(QTXImagePickerFinishAction)finishAction;


@end

#import"QTXImagePicker.h"

@interfaceQTXImagePicker()

@property(nonatomic,weak)UIViewController*viewController;
@property(nonatomic,copy)QTXImagePickerFinishActionfinishAction;
@property(nonatomic,assign)BOOLallowsEditing;

@end

staticQTXImagePicker*qtxImagePickerInstance=nil;

@implementationQTXImagePicker

+(void)showImagePickerFromViewController:(UIViewController*)viewControllerallowsEditing:(BOOL)allowsEditingfinishAction:(QTXImagePickerFinishAction)finishAction{
if(qtxImagePickerInstance==nil){
qtxImagePickerInstance=[[QTXImagePickeralloc]init];
}

[qtxImagePickerInstanceshowImagePickerFromViewController:viewController
allowsEditing:allowsEditing
finishAction:finishAction];
}

-(void)showImagePickerFromViewController:(UIViewController*)viewController
allowsEditing:(BOOL)allowsEditing
finishAction:(QTXImagePickerFinishAction)finishAction{
_viewController=viewController;
_finishAction=finishAction;
_allowsEditing=allowsEditing;

UIActionSheet*sheet=nil;

if([UIImagePickerControllerisSourceTypeAvailable:UIImagePickerControllerSourceTypeCamera]){
sheet=[[UIActionSheetalloc]initWithTitle:nil
delegate:self
cancelButtonTitle:@"取消"
destructiveButtonTitle:nil
otherButtonTitles:@"拍照",@"从相册选择",nil];
}else{
sheet=[[UIActionSheetalloc]initWithTitle:nil
delegate:self
cancelButtonTitle:@"取消"
destructiveButtonTitle:nil
otherButtonTitles:@"从相册选择",nil];
}

UIView*window=[UIApplicationsharedApplication].keyWindow;
[sheetshowInView:window];
}

-(void)actionSheet:(UIActionSheet*)actionSheetclickedButtonAtIndex:(NSInteger)buttonIndex{
NSString*title=[actionSheetbuttonTitleAtIndex:buttonIndex];
if([titleisEqualToString:@"拍照"]){
UIImagePickerController*picker=[[UIImagePickerControlleralloc]init];
picker.delegate=self;
picker.sourceType=UIImagePickerControllerSourceTypeCamera;
picker.allowsEditing=_allowsEditing;
[_viewControllerpresentViewController:pickeranimated:YEScompletion:nil];

}elseif([titleisEqualToString:@"从相册选择"]){
UIImagePickerController*picker=[[UIImagePickerControlleralloc]init];
//[picker.navigationBarsetBarTintColor:QTXNavColor];//修改相册的导航条的背景颜色
picker.delegate=self;
picker.allowsEditing=YES;
picker.sourceType=UIImagePickerControllerSourceTypePhotoLibrary;
[_viewControllerpresentViewController:pickeranimated:YEScompletion:nil];

}else{
qtxImagePickerInstance=nil;
}
}

-(void)imagePickerController:(UIImagePickerController*)pickerdidFinishPickingMediaWithInfo:(NSDictionary*)info{
UIImage*image=info[UIImagePickerControllerEditedImage];
if(image==nil){
image=info[UIImagePickerControllerOriginalImage];
}

if(_finishAction){
_finishAction(image);
}

[pickerdismissViewControllerAnimated:YEScompletion:^{}];

qtxImagePickerInstance=nil;
}

-(void)imagePickerControllerDidCancel:(UIImagePickerController*)picker{
if(_finishAction){
_finishAction(nil);
}

[pickerdismissViewControllerAnimated:YEScompletion:^{}];

qtxImagePickerInstance=nil;
}

@end

当使用时，在所需使用的控制器里调用：

[QTXImagePickershowImagePickerFromViewController:selfallowsEditing:YESfinishAction:^(UIImage*image){
if(image){

self.idSideImage=image;
[QTXUploadImagepost:QTX_xsz1Urlimage:imagename:@"xsz1"success:^(idjson){
//第一步请求上传
QTXLog(@"图像上传请求成功%@",json);

self.idSide=json[@"data"];

}failure:^(NSError*error){
QTXLog(@"学生证图像上传请求失败%@",error);
}];
}
}];

第二步和第三步需要和各位自己后台server联调，就属于普通的get/post请求了，这边就不放代码了哟

插一下，我们产品没让拍照的照片存储到相册

//存储图片名称：001.png~009.png

for(inti=1;i<=9;i++){
UIImage*image=[UIImageimageNamed:[NSStringstringWithFormat:@"00%d.png",i]];

UIImageWriteToSavedPhotosAlbum(image,nil,nil,nil);

[NSThreadsleepForTimeInterval:1];
}

以上就是本文的全部内容，希望对大家的学习有所帮助，也希望大家多多支持毛票票。
