mapView的框架是錯誤的

Question

我有一個連接到Outlet的xib中的MapView。我通過代碼爲肖像和風景設置了框架。該框架是正確的，但輸出是錯誤的。爲什麼？

這是我在MapViewController.h代碼：

@interface MapViewController : UIViewController <MKMapViewDelegate>{ 

    } 

    @property (nonatomic, strong)UIImageView * imageView; 
    @property (nonatomic, strong)IBOutlet UIButton * buttonHome; 
    @property (nonatomic, strong)IBOutlet UIButton * buttonMap; 
    @property (nonatomic, strong)IBOutlet UIButton * buttonFavorites; 
    @property (nonatomic, strong)IBOutlet UILabel * labelTitle; 
    @property (nonatomic, strong)IBOutlet MKMapView *mapView; 

和MapViewController.m

@implementation MapViewController 

    @synthesize imageView; 
    @synthesize buttonFavorites; 
    @synthesize buttonHome; 
    @synthesize buttonMap; 
    @synthesize labelTitle; 
    @synthesize mapView; 

    - (id)initWithNibName:(NSString *)nibNameOrNil bundle:(NSBundle *)nibBundleOrNil 
    { 
self = [super initWithNibName:nibNameOrNil bundle:nibBundleOrNil]; 
if (self) { 
    // Custom initialization 
} 
return self; 
} 

-(void) layoutPortrait { 

self.imageView= [[UIImageView alloc] initWithImage:[UIImage imageNamed:@"bar_V.png"]]; 
self.imageView.frame= CGRectMake(self.view.bounds.origin.x, self.view.bounds.origin.y, self.view.bounds.size.width, 80); 
self.imageView.autoresizingMask = UIViewAutoresizingFlexibleWidth; 
self.labelTitle.frame =CGRectMake(14, 83, 121, 54); 
self.buttonFavorites.frame= CGRectMake(109, 485, 33, 33); 
self.buttonHome.frame =CGRectMake(14, 485, 33, 33); 
self.buttonMap.frame=CGRectMake(61, 485, 33, 33); 
self.mapView.frame = CGRectMake(0, 140, 320, 310); 


} 

-(void) layoutLandscape { 

self. imageView= [[UIImageView alloc] initWithImage:[UIImage imageNamed:@"bar_O.png"]]; 
self.imageView.frame= CGRectMake(self.view.bounds.origin.x, self.view.bounds.origin.y,self.view.bounds.size.width,70); 
self.imageView.autoresizingMask = UIViewAutoresizingFlexibleWidth; 
self.labelTitle.frame =CGRectMake(20,72,140,48); 

self.buttonFavorites.frame= CGRectMake(107,237,33,33); 
self.buttonHome.frame =CGRectMake(11,237,33,33); 
self.buttonMap.frame=CGRectMake(59,237,33,33); 
self.mapView.frame = CGRectMake(201,65,367,227); 


} 


- (void)viewDidLoad 
{ 
[super viewDidLoad]; 


UIInterfaceOrientation deviceOrientation= self.interfaceOrientation; 

if(deviceOrientation == UIInterfaceOrientationPortrait || deviceOrientation== UIInterfaceOrientationPortraitUpsideDown) { 
    [self layoutPortrait]; 

} 
else if (deviceOrientation== UIInterfaceOrientationLandscapeRight){ 
    [self layoutLandscape]; 

} 
else if (deviceOrientation==UIInterfaceOrientationLandscapeLeft){ 

    [self layoutLandscape]; 

} 

[self.view addSubview:self.imageView]; 
[self.view addSubview:self.mapView]; 
[self.view addSubview:self.labelTitle]; 
[self.view addSubview:self.buttonHome]; 
[self.view addSubview:self.buttonMap]; 
[self.view addSubview:self.buttonFavorites]; 


self.mapView.delegate=self; 
} 

-(void) willRotateToInterfaceOrientation:(UIInterfaceOrientation)toInterfaceOrientation duration:(NSTimeInterval)duration { 
[super willRotateToInterfaceOrientation:toInterfaceOrientation duration:duration]; 
UIDeviceOrientation deviceOrientation = [[UIDevice currentDevice]orientation]; 

if(self.imageView){ 
    [self.imageView removeFromSuperview]; 

} 

if(deviceOrientation == UIInterfaceOrientationPortrait || deviceOrientation== UIInterfaceOrientationPortraitUpsideDown) { 
    [self layoutPortrait]; 

} 
else if (deviceOrientation== UIInterfaceOrientationLandscapeRight){ 
    [self layoutLandscape]; 

} 
else if (deviceOrientation==UIInterfaceOrientationLandscapeLeft){ 

    [self layoutLandscape]; 

} 

[self.view addSubview:self.mapView]; 
[self.view addSubview:self.labelTitle]; 
[self.view addSubview:self.imageView]; 
[self.view addSubview:self.buttonFavorites]; 
[self.view addSubview:self.buttonHome]; 
[self.view addSubview:self.buttonMap]; 


} 

我在做什麼錯？

Answer 1

幾件事情：

1）你有你的MKMapView在廈門國際銀行文件自動大小？這可能會干擾您在代碼上所做的事情。

2）你應該在正確的地方處理旋轉邏輯，而不是在viewDidLoad。在UIViewController Class reference上，檢查部分處理查看旋轉，以便您可以看到將代碼放在哪裏。
