数据库异常捕获

注册异常处理Handler

• 数据库异常对象

objc/**
 *  数据库异常信息
 */
@interface NIMDatabaseException : NSObject

/**
 * 异常
 */
@property (nonatomic,assign,readonly) NIMDatabaseExceptionType exception;

/**
 *  数据库异常信息
 */
@property (nullable,nonatomic,copy,readonly) NSString * message;

/**
 *  数据库文件沙盒路径
 */
@property (nullable,nonatomic,copy,readonly) NSString * databasePath;

/**
 *  注册数据库异常处理对象
 *  @param handler 用户自定义处理对象
 */
+ (void)registerExceptionHandler:(id<NIMDatabaseHandleExceptionProtocol>)handler;

@end

实例代码：

objcNTESDbExceptionHandler * handler = [[NTESDbExceptionHandler alloc] init];
[NIMDatabaseException registerExceptionHandler:handler];

• Demo展示

objc// NTESDbExceptionHandler.m
@implementation NTESDbExceptionHandler

- (void)handleException:(NIMDatabaseException *)exception
{
    self.count ++;
    
    NSString * codeType = nil;
    switch (exception.exception) {

        case NIMDatabaseExceptionTypeBadDb:
            codeType = @"数据库损坏";
            break;
        default:
            break;
        }

    
    NSString * msg = [NSString stringWithFormat:@"总次数%zu\n错误:%@\n信息:%@\n路径:%@\n",self.count, codeType,exception.message, exception.databasePath];
    NSLog(@"handleException: %@",msg);
    [[UIApplication sharedApplication].keyWindow hideToasts];
    [[UIApplication sharedApplication].keyWindow makeToast:msg
                                                  duration:3
                                                  position:CSToastPositionCenter];
}
@end

透传

透传Http请求到应用服务

objective-c@protocol NIMPassThroughManager  <NSObject>

/**
 *   透传HTTP请求到应用服务
 *
 *  @param reqData      透传的Http数据
 *  @param completion   经验操作完成后的回调
 *  @discussion         操作成功后，云信服务器会下发禁言的群通知消息
 */
- (void)passThroughHttpReq:(NIMPassThroughHttpData *)reqData
                completion:(nullable NIMPassThroughCompletedBlock)completion;

属性列表

参数	类型	说明
reqData	NIMPassThroughHttpData	透传的Http数据
completion	NIMPassThroughCompletedBlock	经验操作完成后的回调

透传回调

objective-c/**
 *  透传服务管理回调
 */
@protocol NIMPassThroughManagerDelegate <NSObject>

@optional

/**
*  收到透传消息
*
*  @param recvData   收到的透传消息数据
*/
- (void)didReceivedPassThroughMsg:(NIMPassThroughMsgData* __nullable)recvData;

@end

回调管理

objective-c[NIMSDK.sharedSDK.passThroughManager addDelegate:yourDelegate]; // 注册回调
[NIMSDK.sharedSDK.passThroughManager removeDelegate:yourDelegate]; // 注销回调
