在编写 Swift 代码的时候，执行如下代码的时候：
|
1 2 3 4 5 |
var pbCert = Data() let err = pbCert.withUnsafeBytes { buffer in let pulSize: CUnsignedInt = pbCert.count return doSomeThings(buffer, pulSize) } |
出现如下警告：
|
1 |
‘withUnsafeBytes’ is deprecated: use `withUnsafeBytes(_: (UnsafeRawBufferPointer) throws -> R) rethrows -> R` instead |
修正警告的方式，参考使用如下代码：
|
1 2 3 4 5 6 |
var pbCert = Data() let err = pbCert.withUnsafeBytes { buffer in let byteBuffer = buffer.bindMemory(to: UInt8.self) let pulSize: CUnsignedInt = CUnsignedInt(byteBuffer.count) return doSomeThings(byteBuffer.baseAddress!, pulSize) } |
