MKMapView的錯誤

Question

當我在地圖下方創建故事板時，會佔用整個屏幕。這是可以理解的，我用下面的代碼來使用視圖的整個邊界。但是，如果我做一個正常的「初始化」，我會失去地圖的功能！地圖通常會放大我的位置和其他一些東西。當我使用init而不是initWithFrame時，地圖不會到達我的位置。

self.myMapView =[[MKMapView alloc]initWithFrame:self.view.bounds]; 

self.myMapView.delegate=self; 

如何初始化地圖而不需要像我的故事板中顯示的那樣接管整個屏幕。 iOS新手，感謝您的幫助！

//Setting up the location manger for finding the User's location 
self.locationManager = [[CLLocationManager alloc]init]; 
self.locationManager.delegate = self; 

//Check to see if they have Authorization to use to use location servieces 
if ([self.locationManager respondsToSelector:@selector(requestAlwaysAuthorization)]) 
{ 
    [self.locationManager requestAlwaysAuthorization]; 
} 

    [self.locationManager startUpdatingLocation]; 


//Initialize the map and specifiy bounds 
self.myMapView =[[MKMapView alloc]initWithFrame:self.view.bounds]; 

//Set the delegate to itself 
self.myMapView.delegate=self; 

//Set a standard mapview, Enable scrolling and zooming 
self.myMapView.mapType = MKMapTypeStandard; 
self.myMapView.scrollEnabled = YES; 
self.myMapView.zoomEnabled = YES; 
//specifcy resizing 
self.myMapView.autoresizingMask = UIViewAutoresizingFlexibleWidth |  UIViewAutoresizingFlexibleTopMargin; 

//show the User's location and set tracking mode 
self.myMapView.showsUserLocation = YES; 
self.myMapView.userTrackingMode = MKUserTrackingModeFollow; 

//add the VIEW!! 
[self.view addSubview:self.myMapView]; 

//Set up the UISearch Bar 
self.mySearch = [[UISearchBar alloc]init]; 
self.mySearch.delegate = self; 

//Set the initial Text 
self.mySearch.prompt = @"Enter Address or Use Current Location";

有創建地圖視圖兩種方法。

1.創建代碼。如你的例子所示。您需要設置地圖視圖框架。如果您首先需要創建UISearchBar，則應根據搜索欄位置設置地圖視圖框架。它可能看起來像這樣。

self.mySearch = [[UISearchBar alloc] init]; 
self.mySearch.frame = CGRectMake(0, 0, self.view.frame.size.width, 40); 
//... 
self.myMapView = [[MKMapView alloc] init]; 
self.myMapView.frame = CGRectMake(0, self.mySearch.frame.size.height, self.view.frame.size.width, self.view.frame.size.height - self.mySearch.frame.size.height); 
//... 

2.更簡單的方法 - 創建故事板。首先，不需要在代碼中創建您的網點（例如搜索欄和地圖視圖）。您只需簡單拖動即可拖放所有要查看的控件。打開故事板，將視圖控制器類從UIViewController設置爲您的類名稱。

注意的屬性必須是IBOutlets

@property (nonatomic,weak) IBOutlet MKMapView *myMapView; 
@property (nonatomic,weak) IBOutlet UISearchBar *mySearchBar; 

下探您的控件來查看後，必須可視控件連接到你的類網點。看看這個連接被解釋的tutorial。
