對於 ios 項目中 warning 黃色警告的去除

zipArchive 包里面有兩個已經被棄用的方法：

NSDictionary* attr = [[NSFileManager defaultManager] fileAttributesAtPath:file traverseLink:YES]; 
warning: 'fileAttributesAtPath:traverseLink:' is deprecated

解決：改為

NSError* error;

NSDictionary* attr = [[NSFileManager defaultManager] attributesOfItemAtPath:file error:&error];

NSString * strPath = [NSString  stringWithCString:filename];

warning:stringWithCString is deprecated

解決：改為

NSString * strPath = [NSString stringWithCString:filename encoding:NSASCIIStringEncoding];

2.JSONKit 的幾個錯誤

   warning:   Direct access to objective-c's isa is deprecated in favor of object_setClass() and object_getClass()

解決方案： replacing    object->isa   with   object_getClass(object)

You will also need to replace   keyObject->isa   with   object_getClass(keyObject)    and   (id)keys[idx]->isa  with  object_getClass((id)keys[idx])

jsonkit 還有 %lu與%u的提示 replace就可以
