IOS开发之文件上传

#import <UIKit/UIKit.h>

#import "AFHTTPRequestOperationManager.h"

@interface FKAppDelegate :UIResponder <UIApplicationDelegate>

@property (strong,nonatomic)UIWindow *window;

@property (strong,nonatomic)AFHTTPRequestOperationManager* manager;

@end

然后在 FKAppDelegate.m文件初始化

#import "FKAppDelegate.h"

@implementation FKAppDelegate

- (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions

{

self.manager = [AFHTTPRequestOperationManagermanager];

self.manager.responseSerializer = [[AFHTTPResponseSerializeralloc]init];

    return YES;

}

然后在自己定义ViewController主要做如下操作

#import "FKViewController.h"

#import "FKAppDelegate.h"

@interface FKViewController ()

{

FKAppDelegate* appDelegate;

NSArray* images;

}

@end

@implementation FKViewController

- (void)viewDidLoad

{

    [superviewDidLoad];

appDelegate = [UIApplicationsharedApplication].delegate;

self.picker.dataSource = self;

self.picker.delegate = self;

// 使用简化语法创建NSArray集合

images =@[@"logo",@"java" , @"android"];

}

// UIPickerViewDataSource中定义的方法，该方法返回值决定该控件包含多少列

- (NSInteger)numberOfComponentsInPickerView:(UIPickerView*)pickerView

{

//返回1表明该控件只包含1列

return1;

}

-(NSInteger)pickerView:(UIPickerView *)pickerView

numberOfRowsInComponent:(NSInteger)component

{

returnimages.count;

}

#define kImageTag 1

- (UIView *)pickerView:(UIPickerView *)pickerView viewForRow:

(NSInteger)row forComponent:(NSInteger)component

reusingView:(UIView *)view

{

//如果可重用的view的tag不等于kImageTag，表明该view已经不存在，需要重新创建

if(view.tag !=kImageTag)

{

view = [[UIViewalloc]init];

// 为该UIView设置tag属性

view.tag =kImageTag;

//设置不允许用户交互

view.userInteractionEnabled =NO;

UIImageView* iv = [[UIImageViewalloc]initWithImage:

[UIImageimageNamed:[imagesobjectAtIndex:row]]];

iv.frame =CGRectMake(0 ,0  , 48 ,48);

iv.contentMode =UIViewContentModeScaleAspectFit;

[viewaddSubview:iv];

}

return view;

}

// UIPickerViewDelegate中定义的方法，该方法的返回值决定列表项的高度

- (CGFloat)pickerView:(UIPickerView *)pickerView

rowHeightForComponent:(NSInteger)component

{

return48;

}

// UIPickerViewDelegate中定义的方法，该方法的返回值决定列表项的宽度

- (CGFloat)pickerView:(UIPickerView *)pickerView

widthForComponent:(NSInteger)component

{

return48;

}

- (IBAction)upload:(id)sender

{

//获取用户选中的行

NSInteger selectedRow = [self.pickerselectedRowInComponent:0];

//获取用户选中的文件名

NSString* fileName = [imagesobjectAtIndex:selectedRow];

//根据用户选中的文件名确定需要上传的文件

NSURL *filePath = [[NSBundlemainBundle]URLForResource:fileName

withExtension:@"png"];

NSDictionary *parameters =@{@"name":@"额外的请求参数"};

// 使用AFHTTPRequestOperationManager发送POST请求

[appDelegate.manager

POST:@"http://192.168.1.88:8888/AFNetworkingServer/upload"

parameters:parameters

//使用代码块来封装要上传的文件数据

constructingBodyWithBlock:^(id<AFMultipartFormData> formData)

{

[formDataappendPartWithFileURL:filePath // 指定上传的文件

name:@"file" //指定上传文件对应的请求参数名

//指定上传文件的原始文件名

fileName:[NSStringstringWithFormat:@"%@.png" ,fileName]

//指定上传文件的MIME类型

mimeType:@"image/png"

error:nil];

}

//获取服务器响应成功时激发的代码块

success:^(AFHTTPRequestOperation *operation,id responseObject)

{

//当使用HTTP响应解析器时，服务器响应数据被封装在NSData中

// 此处将NSData转换成NSString、并使用UIAlertView显示登录结果

[[[UIAlertViewalloc]initWithTitle:@"上传结果" message:

  [[NSStringalloc]initWithData:responseObjectencoding:

NSUTF8StringEncoding]delegate:self

cancelButtonTitle:@"确定"otherButtonTitles:nil]

show];

}

//获取服务器响应失败时激发的代码块

failure:^(AFHTTPRequestOperation *operation,NSError *error)

{

NSLog(@"获取服务器响应出错！");

}];

}

@end
