问题描述
这里出现错误.绞尽脑汁.各种组合都试过了.
Getting an error here. Racking my brain. Tried all sorts of combinations.
找不到类型为NSDictionary"的初始化程序，它接受类型为(object:(Int), forKey: CFString!)"的参数列表
// configure the pixel format - Obj-C
// videoOutput.videoSettings = [NSDictionary dictionaryWithObjectsAndKeys:[NSNumber numberWithUnsignedInt:kCVPixelFormatType_32BGRA], (id)kCVPixelBufferPixelFormatTypeKey, nil];
// Swift
videoOutput.videoSettings = NSDictionary(object: Int(kCVPixelFormatType_32BGRA), forKey:kCVPixelBufferPixelFormatTypeKey)
推荐答案
更新:Xcode 7.0 • Swift 2.0
videoOutput.videoSettings = NSDictionary(object: Int(kCVPixelFormatType_32BGRA), forKey: kCVPixelBufferPixelFormatTypeKey as String) as [NSObject : AnyObject]
或者只是
videoOutput.videoSettings = [kCVPixelBufferPixelFormatTypeKey : Int(kCVPixelFormatType_32BGRA)]
