Validate the Crash Analysis feature-Enterprise Mobile Application Studio(EMAS)-阿里云帮助中心

1. Report a crash

Write test code to simulate or trigger an app crash. For example:

Important
Do not run the app in the Xcode debugger. The SDK does not catch crashes in the Xcode debugger.
Object C
```
NSMutableArray *array = @[];
[array addObject:nil]; // crash
```
Swift
```
let someNilString: String? = nil
let forcedValue: String = someNilString!
print("Value: \(forcedValue)")
```
After the crash is triggered, wait about 2 minutes and view the data on the Crash page in the console.
Note
- Crash data appears in the console about 2 to 3 minutes after it is collected.
- In some scenarios, crash data is uploaded after the application restarts.

2. Set custom dimensions

Write test code to call the SDK and set custom dimensions. For example:

Object C

#import "AlicloudApmCore/AlicloudApmCore.h"

[[EAPMApm defaultApm] setCustomValue:@"value" forKey:@"key"];

[[EAPMApm defaultApm] setCustomKeysAndValues:@{
    @"key1":@"value1",
    @"key2":@"value2",
}];

Swift

#import "AlicloudApmCore/AlicloudApmCore.h"

let apm = EAPMApm.defaultApm()
apm.setCustomValue("value", forKey: "key")
apm.setCustomKeysAndValues([
    "key1": "value1",
    "key2": "value2"
])

About 2 minutes after you trigger a crash, you can view the report on the Crash page in the console, as shown in the red box in the following image.

3. Report a custom exception

Write test code to call the SDK and report a custom exception. For example:

Object C

#import "AlicloudApmCrashAnalysis/AlicloudApmCrashAnalysis.h"

NSError *error = [NSError errorWithDomain:@"customError" code:10001 userInfo:@{@"errorInfoKey":@"errorInfoValue"}];

[[EAPMCrashAnalysis crashAnalysis] recordError:error userInfo:@{
    @"key1":@"value1",
    @"key2":@"value2",
}];

Swift

#import "AlicloudApmCrashAnalysis/AlicloudApmCrashAnalysis.h"

let crashAnalysis = CrashAnalysis.crashAnalysis()
let error = NSError(
    domain: "customError",
    code: 10001,
    userInfo: [
        "errorInfoKey": "errorInfoValue",
    ]
)
crashAnalysis.record(error: error, userInfo: [
    "key1": "value1",
    "key2": "value2"
])

After the application restarts, you can view the data on the Custom Exception page in the console.
