Question

我在我的应用中有这部分代码

(void) trackWithCategory:(NSString*)category withAction:(NSString*)action withValue:(float)value
{
    AppController *ac = (AppController*) [UIApplication sharedApplication].delegate;
    BOOL result = [ac.tracker trackEventWithCategory:category
                                          withAction:action
                                           withLabel:[UIDevice currentDevice].uniqueIdentifier
                                           withValue:[NSNumber numberWithInt:(int)(value+0.5)]];
    if (!result)
        NSLog(@"Google Analytics track event failed");

}

当我正在尝试构建它时，我对此行提出了错误：

withLabel:[UIDevice currentDevice].uniqueIdentifier

它的权利，首先在ios 5中弃用uniqueidentifier

请我该怎么办呢？我怎么能以不同的方式写它以便它可以......？

使用CFUUID

使用NSUserdefaults

一些样本

NSString *identifierString = [[NSUserDefaults standardUserDefaults] objectForKey:@"myID"];
if (!identifierString) {
    CFUUIDRef identifier = CFUUIDCreate(NULL);
    identifierString = (NSString*)CFUUIDCreateString(NULL, identifier);
    [[NSUserDefaults standardUserDefaults] setObject:identifierString forKey:@"myID"];
}
NSLog(@"%@",identifierString);
/* ... */

uniqueidentifier在ios 5中首先被弃用
