- (void)viewDidLoad { [super viewDidLoad]; UIButton *loginBtn = [UIButton buttonWithType:UIButtonTypeRoundedRect]; loginBtn.frame = CGRectMake(100, 20, 120, 40); [loginBtn setTitle:@"登录" forState:UIControlStateNormal]; [loginBtn addTarget:self action:@selector(login) forControlEvents:UIControlEventTouchUpInside]; [self.view addSubview:loginBtn]; UIButton *uploadBtn = [UIButton buttonWithType:UIButtonTypeRoundedRect]; uploadBtn.frame = CGRectMake(100, 80, 120, 40); [uploadBtn setTitle:@"上传" forState:UIControlStateNormal]; [uploadBtn addTarget:self action:@selector(upload) forControlEvents:UIControlEventTouchUpInside]; [self.view addSubview:uploadBtn];} |

- (void)login { NSURL *url = [NSURL URLWithString:@"..."];//此处省略请求url //请求 ASIHTTPRequest *request = [ASIHTTPRequest requestWithURL:url]; request.tag = 10; request.delegate = self; [request startAsynchronous];}- (void)upload { NSURL* url = [NSURL URLWithString:@"..."];//此处省略请求url UIImage* img = [UIImage imageNamed:@"haoyou.png"]; NSData* data = UIImagePNGRepresentation(img); //ASIFormDataRequest请求是post请求,可以查看其源码 ASIFormDataRequest* request = [ASIFormDataRequest requestWithURL:url]; request.tag = 20; request.delegate = self; [request setPostValue:self.m_auth forKey:@"m_auth"];// [request setFile:@"tabbar.png" forKey:@"haoyou"];//如果有路径,上传文件 [request setData:data withFileName:@"tmp.png" andContentType:@"image/png" forKey:@"headimage"];// 数据 文件名,随便起 文件类型 设置key [request startAsynchronous];} |
