数组转Json串

数组转可上传json串

  NSString *infoStr = [CommonFunction JSONStringWithDictionaryOrArray:introArr.copy];
    DLog(@"infoStr == %@",infoStr);
    //去除空格 和 反斜杠
    NSMutableString *mutStr = [NSMutableString
                               stringWithString:infoStr];
    NSRange range = {0,infoStr.length};
    [mutStr replaceOccurrencesOfString:@" "
     
                            withString:@""
     
                               options:NSLiteralSearch range:range];
    
    NSRange range2 = {0,mutStr.length};
    
    [mutStr replaceOccurrencesOfString:@"\n"
     
                            withString:@""
     
                               options:NSLiteralSearch range:range2];
    NSRange range3 = {0, mutStr.length};
    NSString * str = @"\\";
    [mutStr replaceOccurrencesOfString:str withString:@"" options:NSLiteralSearch range:range3];
