UIView不調整大小以適應內容

我有UIView（annotationView），它有2個UILabels，一些分隔符和1個圖像。我想調整視圖的大小，因此它具有最小的大小，以適應內部元素。它具有約束條件以堅持視圖的邊緣並保持元素之間的距離。 UIView不調整大小以適應內容

當使用annotationView，我只是創建UIView並設置它的類annotationView在IB（下面的圖片黃色）。它沒有約束，但它總是以我在Interface Builder中創建的大小顯示。

我應該重新檢查並設置以適合的角度最小尺寸的內容？

我實現annotationView的：

//used when loading from storyboard 
-(instancetype)initWithCoder:(NSCoder *)aDecoder { 
    DLog(@"Initializing ICProgressPlotAnnotationView - from XIB"); 
    self = [super initWithCoder:aDecoder]; 
    if (self) { 
     [self commonInit]; 
    } 
    return self; 
} 


- (void)commonInit { 
    //load the interface file from .xib 
    [[NSBundle mainBundle] loadNibNamed:@"ICProgressPlotAnnotationView" owner:self options:nil]; 

    _view.frame = self.frame; 
    [_view setNeedsDisplay]; //view is linked to the main view in .xib see image below 

    DLog(@"ICProgressPlotAnnotationView VIEW frame: %@", NSStringFromCGRect(self.view.bounds)); 
    DLog(@"ICProgressPlotAnnotationView frame: %@", NSStringFromCGRect(self.bounds)); 
    //add as a subview 
    [self addSubview:self.view]; 

    [_title_DOWNLabel sizeToFit]; 
    [_title_UPLabel sizeToFit]; 
}

EDIT1：

的約束附加信息：

編輯2：現在我想改變標籤每次，我也在這兩個電話上撥打sizeToFit阿貝爾斯和_view財產annotationView。

之後他們改變大小，但_view沒有。

有什麼建議嗎？

編輯3：也分享我的viewHierarchy：

你給了什麼樣的限制？ –

增加了有關約束的信息：通常所有元素都必須保持距離以查看badaries（並且它們保留，但它們正在調整大小，而不是視圖本身）。沒有指定固有尺寸。 – izik461

最終結果時間的高度是多少？如果它沒有內容，那麼調用sizetofit可能會使高度爲0. – user1079052

最後我得到了它的工作。不完全確定它爲什麼會發生，但是當使黃色視圖小於所需大小（例如，總是小於內部計劃的內容）時，它會調整大小以適當增大。改變contentHugging和Content Compression阻力的優先順序做了這項工作。
