iOS 获取崩溃日志

新建一个类CatchCrash

@interface CatchCrash : NSObject
void uncaughtExceptionHandler(NSException *exception);
@end

@implementation CatchCrash
void uncaughtExceptionHandler(NSException *exception){
    
    NSArray *stackArry= [exception callStackSymbols];

    NSString *reason = [exception reason];
    
    NSString *name = [exception name];
    
    NSString *exceptionInfo = [NSString stringWithFormat:@"Exception name:%@\nException reatoin:%@\nException stack :%@",name,reason,stackArry];
    NSLog(@"exceptionInfo------>");
    NSLog(@"%@",exceptionInfo);
    
    //保存到本地沙盒中
    
    [exceptionInfo writeToFile:[NSString stringWithFormat:@"%@/Documents/error.log",NSHomeDirectory()] atomically:YES encoding:NSUTF8StringEncoding error:nil];
    
    
    
}


@end

AppDelegate导入头文件，在- (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions中加入如下处理，获取log文件之后就可以走接口提交到后台了，在后台查看相关日志。

    //注册消息处理函数的处理方法
    
    NSSetUncaughtExceptionHandler(&uncaughtExceptionHandler);
    
    // 发送崩溃日志
    
    NSString *path = [NSSearchPathForDirectoriesInDomains(NSDocumentDirectory, NSUserDomainMask, YES) lastObject];
    
    NSString *dataPath = [path stringByAppendingPathComponent:@"error.log"];
    
    NSData *data = [NSData dataWithContentsOfFile:dataPath];
    
    if (data != nil) {
        //上传log
        
    }
