Question

工作，我有添加滾動視圖與界面構建及其在NSWindow鑑於實施和NSScrollview我加入CustomView我使用這行代碼在我

AppDelegate.m

- (void)awakeFromNib 

id docView = paintingfield; 
id viewas = [[NSScrollView alloc] initWithFrame: 
          [[scrollview contentView] frame]]; 
[scrollview setHasVerticalScroller:YES]; 
[scrollview setHasHorizontalScroller:YES]; 
[scrollview setBorderType:NSNoBorder]; 
[scrollview setAutoresizingMask:NSViewWidthSizable|NSViewHeightSizable]; 
[scrollview setDocumentView:docView]; 
[scrollview setContentView:viewas]; 

一個在我AppDelegate.h

IBOutlet NSScrollView * scrollview; 
IBOutlet NSView * view; 
IBOutlet CustomView *paintingfield; 

IBOutlets被propertly鏈接NSScrollView到NSScrollView，NSView到CustomView，CustomView到CustomView。 -awakeFromNib被稱爲 問題是因爲NSScrollView當我打開圖像我得到空白窗口，而不是打開圖像滾動沒有NSScrollView圖像打開適當太任何想法我怎麼能修復它？

試着改變你這樣的代碼：

- (void)awakeFromNib 
{ 
    [scrollview setHasVerticalScroller:YES]; 
    [scrollview setHasHorizontalScroller:YES]; 
    [scrollview setBorderType:NSNoBorder]; 
    [scrollview setAutoresizingMask:NSViewWidthSizable|NSViewHeightSizable]; 
    [scrollview setDocumentView:paintingfield]; 
    [scrollView.documentView setFrame: CGRectMake(0, 0, paintingfield.frame.size.width,paintingfield.frame.size.height) ]; 
}
