[NSImage 窗口]：无法识别的选择器发送到 PyObjC 中的实例 0x7fbb246a9e10

如何解决[NSImage 窗口]：无法识别的选择器发送到 PyObjC 中的实例 0x7fbb246a9e10

我正在尝试通过在 Python 中调用 .addSubvew_(image) 方法将图像添加到 NSPanel，但我一直收到 [NSImage window]: unrecognized selector sent to instance 0x7fbb246a9e10。我不确定问题是否是图像的初始化问题，或者我是否错误地添加了子视图。但似乎初始化工作得很好，因为它在单独运行时不会出现任何错误。完整代码如下：

from Cocoa import NSObject,NSApplication,NSApp,NSWindow,NSPanel,NSColor,NSImage,NSSound
from PyObjCTools import AppHelper

def main():
    NSApplication.sharedApplication()

    # we must keep a reference to the delegate object ourselves,# NSApp.setDelegate_() doesn't retain it. A local variable is
    # enough here.
    delegate = NSPanel.alloc().init()
    NSApp().setDelegate_(delegate)

    win = NSPanel.alloc()
    frame = ((875.0,140.0),(180.0,200.0))
    win.initWithContentRect_styleMask_backing_defer_(frame,9395,5)
    win.setLevel_(0)  # floating window

    image1 = NSImage.alloc()
    image1.initWithContentsOfFile_('/Users/yassine/Teams.png')
    win.contentView().addSubview_(image1)
    win.display()
    win.orderFrontRegardless()  # but this one does
    AppHelper.runEventLoop()

if __name__ == "__main__":
    main()

解决方法

NSView 的 addSubview: 方法添加了一个 view - 您需要为图像创建一个视图。使用 NSImageView 并替换您的图像语句将类似于：

#add NSImageView to the import
image = NSImage.alloc().initWithContentsOfFile_('/Users/yassine/Teams.png')
view = NSImageView.alloc().initWithFrame_(((10,10),(150.0,150.0)))
view.setImage_(image)
win.contentView().addSubview_(view)
