项目介绍：

JJException

保护App,一般常见的问题不会导致闪退，增强App的健壮性，同时会将错误抛出来，根据每个App自身的日志渠道记录，下次迭代或者热修复以下问题.

• Unrecognized Selector Sent to Instance

• NSArray,NSMutableArray,NSDictonary,NSMutableDictionary

• KVO

• Zombie Pointer

• NSTimer

• NSNotification

如何安装

pod 'JJException'

如何使用

• 所有异常的分类,根据自身需要，自由组合

typedef NS_OPTIONS(NSInteger,JJExceptionGuardCategory){
    JJExceptionGuardNone = 0,
    JJExceptionGuardUnrecognizedSelector = 1 << 1,
    JJExceptionGuardDictionaryContainer = 1 << 2,
    JJExceptionGuardArrayContainer = 1 << 3,
    JJExceptionGuardZombie = 1 << 4,
    JJExceptionGuardKVOCrash = 1 << 5,
    JJExceptionGuardNSTimer = 1 << 6,
    JJExceptionGuardNSNotificationCenter = 1 << 7,
    JJExceptionGuardAll = JJExceptionGuardUnrecognizedSelector | JJExceptionGuardDictionaryContainer | JJExceptionGuardArrayContainer | JJExceptionGuardZombie | JJExceptionGuardKVOCrash | JJExceptionGuardNSTimer | JJExceptionGuardNSNotificationCenter,
};

• 设置异常类型并开启

    [JJException configExceptionCategory:JJExceptionGuardAll];
    [JJException startGuardException];

• 实时关闭保护

    [JJException stopGuardException];

• Zombie使用黑名单机制，只有加入这个名单的才有作用,示例如下:

    [JJException addZombieObjectArray:@[TestZombie.class]];

• 如果需要记录日志，只需要实现JJExceptionHandle协议，并注册:

@interface ViewController ()<JJExceptionHandle>

@end

@implementation ViewController

- (void)viewDidLoad {
    [super viewDidLoad];
    [JJException registerExceptionHandle:self];
}

- (void)handleCrashException:(NSString*)exceptionMessage exceptionCategory:(JJExceptionGuardCategory)exceptionCategory extraInfo:(nullable NSDictionary*)info{

}
