1.上傳appStore的app,可以通過iTunes Stroe獲取
2.利用Xcode獲取。
3. Crashlytics,Hockeyapp ,友盟,Bugly 等等。
4.通過IOS SDK中提供了一個現成的函數 NSSetUncaughtExceptionHandler 用來做異常處理
利用NSSetUncaughtExceptionHandler,當程序異常退出的時候,可以先進行處理,然後做一些自定義的動作,並通知開發者,是大多數軟件都選擇的方法。下面就介紹如何在iOS中實現:
#import <Foundation/Foundation.h>
// 崩潰日誌
@interface MyUncaughtExceptionHandler : NSObject
+ (void)setDefaultHandler;
+ (NSUncaughtExceptionHandler *)getHandler;
+ (void)TakeException:(NSException *) exception;
end

#import "MyUncaughtExceptionHandler.h"

// 沙盒的地址
NSString * applicationDocumentsDirectory() {
return [NSSearchPathForDirectoriesInDomains(NSDocumentDirectory, NSUserDomainMask, YES) lastObject];
}
// 崩潰時的回調函數
void UncaughtExceptionHandler(NSException * exception) {
NSArray * arr = [exception callStackSymbols];
NSString * reason = [exception reason]; // // 崩潰的原因 可以有崩潰的原因(數組越界,字典nil,調用未知方法...) 崩潰的控制器以及方法

// 將一個txt文件寫入沙盒
[url writeToFile:path atomically:YES encoding:NSUTF8StringEncoding error:nil];
}

// 沙盒地址
- (NSString *)applicationDocumentsDirectory {
return [NSSearchPathForDirectoriesInDomains(NSDocumentDirectory, NSUserDomainMask, YES) lastObject];
}

在appledelegate導入頭文件加上一個異常捕獲監聽,用來處理程序崩潰時的回調動作 在這裏也要判斷一下之前有沒有崩潰日誌 如果有發送給服務器
- (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions {
#pragma mark -- 崩潰日誌
[MyUncaughtExceptionHandler setDefaultHandler];
// 發送崩潰日誌
NSString *path = [NSSearchPathForDirectoriesInDomains(NSDocumentDirectory, NSUserDomainMask, YES) lastObject];
NSString *dataPath = [path stringByAppendingPathComponent:@"Exception.txt"];
NSData *data = [NSData dataWithContentsOfFile:dataPath];
if (data != nil) {
[self sendExceptionLogWithData:data path:dataPath];
}
return YES;
}
#pragma mark -- 發送崩潰日誌
- (void)sendExceptionLogWithData:(NSData *)data path:(NSString *)path {
AFHTTPSessionManager *manager = [AFHTTPSessionManager manager];
manager.requestSerializer.timeoutInterval = 5.0f;
//告訴AFN,支持接受 text/xml 的數據
[AFJSONResponseSerializer serializer].acceptableContentTypes = [NSSet setWithObject:@"text/plain"];
NSString *urlString = @"後臺地址";
[manager POST:urlString parameters:nil constructingBodyWithBlock:^(id<AFMultipartFormData> _Nonnull formData) {
[formData appendPartWithFileData:data name:@"file" fileName:@"Exception.txt" mimeType:@"txt"];
} success:^(NSURLSessionDataTask * _Nonnull task, id _Nonnull responseObject) {
// 刪除文件
NSFileManager *fileManger = [NSFileManager defaultManager];
[fileManger removeItemAtPath:path error:nil];
} failure:^(NSURLSessionDataTask * _Nonnull task, NSError * _Nonnull error) {
}];
}
