   修改UITextField 的内部属性

 NSMutableAttributedString*attrString = [[NSMutableAttributedStringalloc] initWithString:@"用户名字 / 名称"attributes:@{NSForegroundColorAttributeName:[UIColor colorWithHexString:@"B3B3B3"],NSFontAttributeName:[UIFont boldSystemFontOfSize:26]}];

定义三原色

//NSError

#define ErrorMsg(text) [NSError errorWithDomain:NSCocoaErrorDomain code:NSURLErrorNotConnectedToInternet userInfo:[NSDictionary dictionaryWithObject:text forKey:NSLocalizedDescriptionKey]]

//获取当前版本号

#define BUNDLE_VERSION [[[NSBundle mainBundle] infoDictionary] objectForKey:@"CFBundleVersion"]

//获取当前版本的biuld

#define BIULD_VERSION [[NSBundle mainBundle] objectForInfoDictionaryKey:@"CFBundleShortVersionString"]

//获取当前设备的UDID

#define DIV_UUID [[[UIDevice currentDevice] identifierForVendor] UUIDString]

//GCD - 延迟执行
