如果传递给Performance.startTrace(name:)的字符串超过100个字符，请小心。在内部，他们正在一个名为NSString *FPRReservableName(NSString *name)的静态方法中对字符串执行一些清理，这不是一个诚实的API，正如你所看到的：

NSString *FPRReservableName(NSString *name) {
NSString *reservableName =
[name stringByTrimmingCharactersInSet:[NSCharacterSet whitespaceCharacterSet]];
if ([reservableName hasPrefix:kFPRInternalNamePrefix]) {
FPRLogError(kFPRClientNameReserved, @"%@ prefix is reserved. Dropped %@.",
kFPRInternalNamePrefix, reservableName);
return nil;
}
if (reservableName.length == 0) {
FPRLogError(kFPRClientNameLengthCheckFailed, @"Given name is empty.");
return nil;
}
if (reservableName.length > kFPRMaxNameLength) {
FPRLogError(kFPRClientNameLengthCheckFailed, @"%@ is greater than %d characters, dropping it.",
reservableName, kFPRMaxNameLength);
return nil;
}
return reservableName;
}

当然，这是完全不可接受的，因为它会在运行时导致意外的崩溃。
