Causing a crash

Want to try out TestFairy's world class crash handler? Use the TestFairy library to invoke a crash, in your app, and see the stacktrace in your app's session.

Syntax

[TestFairy crash];

Note: Available starting iOS SDK version 1.19.8

Code Example


#import "ViewController.h"
#import "TestFairy.h"

@implementation ViewController
- (void)viewDidLoad {
    [super viewDidLoad];

    UIButton* button = [UIButton buttonWithType:UIButtonTypeRoundedRect];
    button.frame = CGRectMake(50, 50, 100, 30);
    [button setTitle:@"Crash" forState:UIControlStateNormal];
    [button addTarget:self action:@selector(crashApp:) forControlEvents:UIControlEventTouchUpInside];
    [self.view addSubview:button];
}

- (IBAction)crashApp:(id)sender {
    [TestFairy crash];
}

@end

Syntax

TestFairy.crash()

Note: Available starting iOS SDK version 1.19.8

Code Example

class ViewController: UIViewController {
    override func viewDidLoad() {

        button.setTitle("Crash", for: [])
        button.addTarget(self, action: #selector(self.crashApp(_:)), for: .touchUpInside)
