我可以从 Mac 上的 Objective-C 找到已连接 Iphone 设备的 UUID 吗？通过 USB 电缆连接的 Iphone 的列表。

尝试一下：

[[UIDevice device] uniqueIdentifier]

对于每个连接的设备。

Try this:

[[UIDevice device] uniqueIdentifier]

for each of your connected devices.

使用 ioreg 命令，并 grep 收到的结果。一个极简的实现：

- (NSString*)getConnectedIphoneUIID
{
NSTask *ioRegTask = [[NSTask alloc] init];
[ioRegTask setLaunchPath:@"/usr/sbin/ioreg"];
[ioRegTask setArguments:[NSArray arrayWithObjects:@"-Src",@"IOUSBDevice",nil]];

NSTask *grepTask = [[NSTask alloc] init];
[grepTask setLaunchPath:@"/usr/bin/grep"];
[grepTask setArguments:[NSArray arrayWithObjects:@"-i", @"usb serial number", nil]];

NSPipe *ioregToGrepPipe = [[NSPipe alloc] init];
[ioRegTask setStandardOutput:ioregToGrepPipe];
[grepTask setStandardInput:ioregToGrepPipe];

NSPipe *outputPipe = [[NSPipe alloc] init];
[grepTask setStandardOutput:outputPipe];
NSFileHandle *outputFileHandle = [[outputPipe fileHandleForReading] retain];

[ioRegTask launch];
[grepTask launch];


NSData *outputData = [[outputFileHandle readDataToEndOfFile] retain];

[ioRegTask release];
[grepTask release];
[outputData release];

NSString *nvcap = [[NSString alloc] initWithData:outputData encoding:NSUTF8StringEncoding];

     return nvcap;
  }

我可以合并更多检查并进一步解析结果，以确保它确实是一部 iPhone，以防万一其中列出了更多设置了“USB 序列号”属性的设备。检查“SupportsIPhoneOS”属性将进一步确认设备的身份。这样，我实际上可以构建已连接的 iPhone/iPod 设备的列表，并从“usb 序列号”属性中获取它们的 UUID。

Use the ioreg command, and grep the received results. A minimalist implementation:

- (NSString*)getConnectedIphoneUIID
{
NSTask *ioRegTask = [[NSTask alloc] init];
[ioRegTask setLaunchPath:@"/usr/sbin/ioreg"];
[ioRegTask setArguments:[NSArray arrayWithObjects:@"-Src",@"IOUSBDevice",nil]];

NSTask *grepTask = [[NSTask alloc] init];
[grepTask setLaunchPath:@"/usr/bin/grep"];
[grepTask setArguments:[NSArray arrayWithObjects:@"-i", @"usb serial number", nil]];

NSPipe *ioregToGrepPipe = [[NSPipe alloc] init];
[ioRegTask setStandardOutput:ioregToGrepPipe];
[grepTask setStandardInput:ioregToGrepPipe];

NSPipe *outputPipe = [[NSPipe alloc] init];
[grepTask setStandardOutput:outputPipe];
NSFileHandle *outputFileHandle = [[outputPipe fileHandleForReading] retain];

[ioRegTask launch];
[grepTask launch];


NSData *outputData = [[outputFileHandle readDataToEndOfFile] retain];

[ioRegTask release];
[grepTask release];
[outputData release];

NSString *nvcap = [[NSString alloc] initWithData:outputData encoding:NSUTF8StringEncoding];

     return nvcap;
  }

I could incorporate more checks and further parse the results, to make sure it's really an iPhone, just in case there are more devices listed in there that have the "usb serial number" property set. Checking the "SupportsIPhoneOS" property would further confirm the device's identity. This way, I could actually build a list of connected iPhone/iPod devices, and get their UUID's from the "usb serial number" property.
