iOS获取本地json 文件数据以及宏定义

//获取文件路径
NSString *filePath = [[NSBundle mainBundle] pathForResource:@"xxx" ofType:@"json"];
//获取文件内容
NSString *jsonStr  = [NSString stringWithContentsOfFile:filePath encoding:NSUTF8StringEncoding error:nil];
//将文件内容转成数据
NSData *jaonData   = [jsonStr dataUsingEncoding:NSUTF8StringEncoding];
//将数据转成数组
NSDictionary *dic= [NSJSONSerialization JSONObjectWithData:jaonData options:NSJSONReadingMutableContainers error:nil];
宏定义

#define getLocalJsonDataWithName(name) ({
      
      \
    NSString *filePath = [[NSBundle mainBundle] pathForResource:name ofType:@"json"];\
    NSString *jsonStr  = [NSString stringWithContentsOfFile:filePath encoding:NSUTF8StringEncoding error:nil];\
    NSData *jaonData   = [jsonStr dataUsingEncoding:NSUTF8StringEncoding];\
    NSDictionary *data = [NSJSONSerialization JSONObjectWithData:jaonData options:NSJSONReadingMutableContainers error:nil];\
    (data);})\
