糯米团—重制“iPhone团购信息客户端”（四）

奥对，忘了说了，Xcode7已经默认https连接了，自动锁定了http连接

Solution：

1. 在Info.plist中添加 NSAppTransportSecurity 类型 Dictionary.

2. 在 NSAppTransportSecurity 下添加 NSAllowsArbitraryLoads 类型Boolean，value为YES

接下来写显示商品详情的类



storyboard上面怎么连接我就不说了，直接上代码。

WebViewController.h

#import <UIKit/UIKit.h>

@interface WebViewController : UIViewController

@property (strong, nonatomic) NSString *stringURL;
@property (strong, nonatomic) NSString *shopName;

@property (weak, nonatomic) IBOutlet UIWebView *webView;
- (IBAction)back:(UIBarButtonItem *)sender;

@end

WebViewController.m

#import "WebViewController.h"

@interface WebViewController ()

@end

@implementation WebViewController

- (void)viewDidLoad {
[super viewDidLoad];
self.navigationItem.title = [NSString stringWithFormat:@"%@", _shopName];
NSURL *url = [NSURL URLWithString:_stringURL];
NSURLRequest *request = [NSURLRequest requestWithURL:url];
[_webView loadRequest:request];
}

- (void)didReceiveMemoryWarning {
[super didReceiveMemoryWarning];
// Dispose of any resources that can be recreated.
}

- (IBAction)back:(UIBarButtonItem *)sender {
[self dismissViewControllerAnimated:YES completion:nil];
}

@end

再来地图



MapViewController.h

#import <UIKit/UIKit.h>
#import <MapKit/MapKit.h>
#import "MyAnnotation.h"

@interface MapViewController : UIViewController <MKMapViewDelegate>

@property (strong, nonatomic) NSString *longtitudeStr;
@property (strong, nonatomic) NSString *latitudeStr;
@property (strong, nonatomic) NSString *shopName;
@property (strong, nonatomic) NSString *shopAddress;

@property (strong, nonatomic) CLLocationManager *locationManager;

@property (weak, nonatomic) IBOutlet MKMapView *map;

- (IBAction)back:(UIBarButtonItem *)sender;

@end

MapViewController.m

#import "MapViewController.h"

@interface MapViewController () {
CLLocationDegrees longitude;
CLLocationDegrees latitude;
}

@property (strong, nonatomic) CLLocation *targetLocation;
@property (strong, nonatomic) MyAnnotation *annotation;

- (void)gecodeToDisplayTargetLocation;

@end

@implementation MapViewController

- (void)viewDidLoad {
[super viewDidLoad];
self.navigationItem.title = _shopAddress;
//定位请求
_locationManager = [CLLocationManager new];
[_locationManager requestWhenInUseAuthorization];
//经纬转换
longitude = (CLLocationDegrees)[_longtitudeStr floatValue];
latitude = (CLLocationDegrees)[_latitudeStr floatValue];
_targetLocation = [[CLLocation alloc] initWithLatitude:latitude longitude:longitude];
_map.delegate = self;

[self gecodeToDisplayTargetLocation];
}

- (void)gecodeToDisplayTargetLocation {
CLGeocoder *geocoder = [[CLGeocoder alloc] init];
[geocoder reverseGeocodeLocation:_targetLocation completionHandler:^(NSArray<CLPlacemark *> * _Nullable placemarks, NSError * _Nullable error) {
//传过来1个数据，所以就一个
CLPlacemark *placemark = placemarks[0];
//显示地图缩放比例
MKCoordinateRegion viewRegion = MKCoordinateRegionMakeWithDistance(placemark.location.coordinate, 500, 500);
[_map setRegion:viewRegion animated:YES];
//设置标注
_annotation = [MyAnnotation new];
_annotation.shopName = _shopName;
_annotation.address = _shopAddress;
_annotation.coordinate = placemark.location.coordinate;
[_map addAnnotation:_annotation];
}];
}

- (void)didReceiveMemoryWarning {
[super didReceiveMemoryWarning];
// Dispose of any resources that can be recreated.
}

#pragma mark - MKMapDelegate implements
- (MKAnnotationView *)mapView:(MKMapView *)mapView viewForAnnotation:(id<MKAnnotation>)annotation {
//使用可重用对象节省内存
MKPinAnnotationView *annotaionView = (MKPinAnnotationView *)[_map dequeueReusableAnnotationViewWithIdentifier:@"PIN_ANNOTATION"];
if (!annotaionView) {
annotaionView = [[MKPinAnnotationView alloc] initWithAnnotation:annotation reuseIdentifier:@"PIN_ANNOTATION"];
}
//设置大头针颜色
annotaionView.pinColor = MKPinAnnotationColorPurple;
//大头针动态插入
annotaionView.animatesDrop = YES;
//显示附加信息在大头针处
annotaionView.canShowCallout = YES;

return annotaionView;
}

- (IBAction)back:(UIBarButtonItem *)sender {
[self dismissViewControllerAnimated:YES completion:nil];
}
@end

至于SecondViewController我没有写代码，这里随便怎么处置了。
