ios - Hook 任何事件并计算执行时间

屏幕上的按钮很少。我需要计算按下任何 ui 元素时的执行时间，但不将其添加到每个按钮。我的功能只能捕捉 View Controller 的触摸。

- (void)touchesBeganNSSet *)touches withEventUIEvent *)event
{

    NSString * strLoad = @"";
    for (int i = 1; i <=100000; i++) {
        strLoad = [strLoad stringByAppendingString"add"];
    }
    NSLog(@"touchesBegan");       
    NSTimeInterval delta = ([[NSProcessInfo processInfo] systemUptime] - [(UIEvent*)event timestamp]);
    NSLog(@"time %.2f", delta);
}
- (void)viewDidLoad {
    [super viewDidLoad];
- (void)didReceiveMemoryWarning {
    [super didReceiveMemoryWarning];
}
- (IBAction)btnMetadataid)sender {
    NSString * strLoad = @"aBC";
    for (int i = 1; i <=500; i++) {
        strLoad = [strLoad stringByAppendingString"add"];
    }
}
- (IBAction)btnGenerateCrashid)sender {
    NSString * strLoad = @"aBC";
    for (int i = 1; i <=5000; i++) {
        strLoad = [strLoad stringByAppendingString"add"];
    }
}
