我需要一点帮助来转换它

 MIDIDeviceRef midiDevice = MIDIGetDevice(i);
NSDictionary *midiProperties;

MIDIObjectGetProperties(midiDevice, (CFPropertyListRef *)&midiProperties, YES);
NSLog(@"Midi properties: %d \n %@", i, midiProperties);

迅速.我有这个,但我正忙着投出CFPropertList.

 var midiDevice = MIDIGetDevice(index)
let midiProperties =  NSDictionary()

 MIDIObjectGetProperties(midiDevice,  CFPropertyListRef(midiProperties), 1);
println("Midi properties: \(index) \n \(midiProperties)");

任何帮助都会很棒.

谢谢

我正在尝试使用带有自定义UI的Twitters新TwitterKit发布图像和推文.他们提供的唯一文档是如何使用他们的视图.

所以我可以弄清楚如何在没有图像的情况下做到这一点

NSMutableDictionary *message = [[NSMutableDictionary alloc] initWithObjectsAndKeys:[params objectForKey:@"description"],@"status",@"true",@"wrap_links", nil];

NSURLRequest* request = [twAPIClient URLRequestWithMethod:@"POST" URL:@"https://api.twitter.com/1.1/statuses/update.json" parameters:message error:nil];

[twAPIClient sendTwitterRequest:request completion:^(NSURLResponse* response, NSData* data, NSError* connectionError){



}];

但是他们的URLRequestWithMethod方法并不可变.我将如何添加图像.你以前用SLRequest做的

[postRequest addMultipartData:UIImageJPEGRepresentation(image, 0.5) withName:@"media" type:@"image/jpeg" filename:@"image.png"];
