如何設置按鈕圖像被創建編程

Question

可能重複：
Using -setImage on NSButton

I created a button using following code . 


    NSView *superview = [_window contentView]; 
    NSRect frame = NSMakeRect(10, 10, 200, 100); 
    button = [[NSButton alloc] initWithFrame:frame]; 
    [button setTitle:@"Click me!"]; 

所以我怎麼可以設定此按鈕，圖像？

Answer 1

你應該使用：

- (void)setImage:(NSImage *)anImage 

例如爲：

[button setImage:[NSImage imageNamed:@"image"]]; 

Answer 2

[button setBackgroundImage:[UIImage imageNamed:@"yourImage"] forState:UIControlStateNormal];
