首先创建控件 然后导入MB 文件夹 MBProgressHUD
导入头文件#import "MBProgressHUD/MBProgressHUD.h"
创建类别文件 NSstring+regular
.h中填写方法:
//判断是否是一个正确的手机号
-(BOOL)isCorrectPhoneNumber;
.m 中实现方法:
//判断是否是一个正确的手机号
-(BOOL)isCorrectPhoneNumber{
//如果不是11位 返回 NO
if(self.length!=11) {
returnNO;
}
//如果够11位, 如果以10 11 开头返回 YES
if ([self hasPrefix:@"13"] || [self hasPrefix:@"14"] || [self hasPrefix:@"15"] || [self hasPrefix:@"16"] || [self hasPrefix:@"17"] || [self hasPrefix:@"18"] || [self hasPrefix:@"19"]) {
returnYES;
}
//剩下的都判定错误
return NO;
}
导入头文件#import "NSString+Regular.h"
控件拖入:
@property (weak, nonatomic) IBOutlet UITextField *phoneTF;
- (IBAction)search:(id)sender;
@property (weak, nonatomic) IBOutlet UITextView *textVi;
//显示提示框
-(void)showMBAlertWithMassage:(NSString*)msg{
MBProgressHUD *hud = [[MBProgressHUD alloc]initWithView:self.view];
hud.mode = MBProgressHUDModeText;
hud.removeFromSuperViewOnHide = YES;
hud.labelText= msg;
[self.viewaddSubview:hud];
[hudshow:YES];
[hudhide:YES afterDelay:2.0];
}
- (IBAction)search:(id)sender {
if(self.phoneTF.text.length==0){
[self showMBAlertWithMassage:@"手机号不可为空"];
return;
}
//做手机号的判断
if ([self.phoneTF.text isCorrectPhoneNumber] == NO) {
[self showMBAlertWithMassage:@"请输入正确的手机号"];
return;
}
//使用 GET 请求网络数据
[self requestNetDataByGET];
//使用 POST 请求网络数据
[self requestNetDataByPOST];
}
//使用 GET 请求网络数据
-(void)requestNetDataByGET{
//显示等待显示器
MBProgressHUD *hud = [[MBProgressHUD alloc]initWithView:self.view];
hud.removeFromSuperViewOnHide = YES;
[self.viewaddSubview:hud];
[hudshow:YES];
// (1)封装网址字符串 并把参数连接到字符串上
NSString *URL = [NSString stringWithFormat:@"http://apis.juhe.cn/mobile/get?phone=%@&key=%@",self.phoneTF.text,@"74a36daf6c9af664e4ef26bbeaa9085c"];
// (2) 将网址字符串封装为地址对象
NSURL*url = [NSURLURLWithString:URL];
// (3) 做一个请求对象 设置缓存策略和超市时长
NSURLRequest *req = [NSURLRequest requestWithURL:url cachePolicy:NSURLRequestReloadIgnoringCacheData timeoutInterval:5.0];
// (4)
[self usesessionRequestData:req hud:hud];
}
POST方法
-(void)requestNetDataByPOST{
//显示等待显示器
MBProgressHUD *hud = [[MBProgressHUD alloc]initWithView:self.view];
hud.removeFromSuperViewOnHide = YES;
[self.viewaddSubview:hud];
[hudshow:YES];
//将网址字符串封装为网址对象
NSURL *url = [NSURL URLWithString:@"http://apis.juhe.cn/mobile/get"];
//做一个请求对象
NSMutableURLRequest *req = [NSMutableURLRequest requestWithURL:url cachePolicy:NSURLRequestReloadIgnoringCacheData timeoutInterval:5.0];
//设置请求方式魏 post
[reqsetHTTPMethod:@"POST"];
//将参数坐成一个字符串
NSString *paramStr = [NSString stringWithFormat:@"phone=%@&key=%@",self.phoneTF.text,@"74a36daf6c9af664e4ef26bbeaa9085c"];
//将参数字符串转换为二进制对象
NSData *parmeData = [paramStr dataUsingEncoding:NSUTF8StringEncoding];
//将参数二进制数据放在请求体中
[reqsetHTTPBody:parmeData];
[self usesessionRequestData:req hud:hud];
}
//请求网络数据
-(void)usesessionRequestData:(NSURLRequest*)req hud:(MBProgressHUD*)hud{
// (3)请求网络数据
NSURLSession *session = [NSURLSession sharedSession];
//(5)请求网络数据任务
NSURLSessionDataTask*task = [sessiondataTaskWithRequest:reqcompletionHandler:^(NSData*_Nullabledata,NSURLResponse*_Nullableresponse,NSError*_Nullableerror) {
//停掉等待指示器
dispatch_async(dispatch_get_main_queue(), ^{
[hudhide:YES];
});
//如果发生服务器错误
if(error !=nil) {
//回到 UI 主线程提示
dispatch_async(dispatch_get_main_queue(), ^{
[self showMBAlertWithMassage:@"服务器错误"];
});
return;
}
//解析 JSON 数据
NSError*jsonError =nil;
id jsonData = [NSJSONSerialization JSONObjectWithData:data options:NSJSONReadingAllowFragments error:&jsonError];
//如果json解析错误 给出提示 并结束调用
if(jsonError !=nil) {
dispatch_async(dispatch_get_main_queue(), ^{
[self showMBAlertWithMassage:@"网络数据错误"];
});
return;
}
//json 解析正确 得到resultcode字段的值不是200 发生错误 给客户提示
if([[jsonDataobjectForKey:@"resultcode"]intValue] !=200) {
//获取reason
NSString*reason = jsonData[@"reason"];
dispatch_async(dispatch_get_main_queue(), ^{
[selfshowMBAlertWithMassage:reason];
});
return;
}
//没有错误 提取归属地信息
NSDictionary*resultDic = jsonData[@"result"];
NSString*province = resultDic[@"province"];
NSString*city = resultDic[@"city"];
NSString*areacode = resultDic[@"areacode"];
NSString*zip = resultDic[@"zip"];
NSString*company = resultDic[@"company"];
NSString*card = resultDic[@"card"];
//用一个字符串拼接到一块
NSString*resultStr = [NSStringstringWithFormat:@"省:%@\n\
市:%@\n\
区号:%@\n\
邮编:%@\n\
公司:%@\n\
类型:%@",province,city,areacode,zip,company,card];
dispatch_async(dispatch_get_main_queue(), ^{
self.textVi.text= resultStr;
});
}];
[taskresume];
}
最后 :info.plist 中开启网络
App Transport Security Settings
Allow Arbitrary Loads 后面跟 YES.
