贼气，网上各种方法没有。
后来一看就是localhost解析不出来
- (NSString *)guessPackagerHost
{
static NSString *ipGuess;
static dispatch_once_t onceToken;
dispatch_once(&onceToken, ^{
NSString *ipPath = [[NSBundle mainBundle] pathForResource:@"ip" ofType:@"txt"];
ipGuess = [[NSString stringWithContentsOfFile:ipPath encoding:NSUTF8StringEncoding error:nil]
stringByTrimmingCharactersInSet:[NSCharacterSet newlineCharacterSet]];
});
NSString *host = ipGuess ?: @"localhost";
if ([self isPackagerRunning:host]) {
return host;
}
看看源代码有加载ip.txt
直接写了一个ip.txt文件，写上自己的网络ip
解决！！！
