我对 objective-c 和IOS是陌生的,我试图将一些值发布到url并尝试获取响应。
但我无法编译我的项目,因为我遇到此错误
导入
#import "SignInVC.h"
#import <QuartzCore/QuartzCore.h>
#import "ApplicationEnvironmentURL.h"
#import "Reachability.h"
#import "AFNetworking/AFNetworking.h"
#import "MBProgressHUD/MBProgressHUD.h"
#import "AppDelegate.h"
目标代码c
- (void)submitLoginRequest:(NSString *)email password:(NSString *)password {
AFHTTPSessionManager *manager = [[AFHTTPSessionManager alloc] initWithSessionConfiguration:[NSURLSessionConfiguration defaultSessionConfiguration]];
manager.requestSerializer = [AFJSONRequestSerializer serializer];
NSMutableDictionary *dict = [[NSMutableDictionary alloc] init];
[dict setValue:email forKey:@"Email"];
[dict setValue:password forKey:@"Password"];
NSLog(@"Login dicxtionary : %@", dict);
MBProgressHUD *hud;
hud = [MBProgressHUD showHUDAddedTo:self.view animated:YES];
hud.label.text = @"Please wait. Logging in...";
[hud showAnimated:YES];
// send user login data to hosting via AFHTTP Async Request in AFNetworking
[manager POST:BASEURL parameters:dict progress:nil success:^(NSURLSessionTask *task, id responseObject) {
[hud hideAnimated:YES];
// Login response validation
if (responseObject == [NSNull null]) {
[self showMessage:@"Login Failed" Message:@"Unable to login. Please try again!"];
}else {
//NSError *error = nil;
NSLog(@"response type : %@", NSStringFromClass([responseObject class]));
//NSDictionary *response = [NSJSONSerialization JSONObjectWithData:responseObject options:NSJSONReadingMutableContainers error:&error];
[self checkResultValue:(NSDictionary *)responseObject];
}
} failure:^(NSURLSessionTask *task, NSError *error) {
NSLog(@"AFHTTPSession Failure : %@", [error localizedDescription]);
}];
}
有人可以帮我解决此问题。 tnx。
最佳答案
您正在寻找的方法是 POST:parameters:success:failure:
。因此,只需从方法调用中删除progress:nil
。整个方法调用如下所示。
[manager POST:BASEURL parameters:dict success:^(NSURLSessionTask *task, id responseObject) {
[hud hideAnimated:YES];
// Login response validation
if (responseObject == [NSNull null]) {
[self showMessage:@"Login Failed" Message:@"Unable to login. Please try again!"];
}else {
//NSError *error = nil;
NSLog(@"response type : %@", NSStringFromClass([responseObject class]));
//NSDictionary *response = [NSJSONSerialization JSONObjectWithData:responseObject options:NSJSONReadingMutableContainers error:&error];
[self checkResultValue:(NSDictionary *)responseObject];
}
} failure:^(NSURLSessionTask *task, NSError *error) {
NSLog(@"AFHTTPSession Failure : %@", [error localizedDescription]);
}];
