# FORGestureTrackDisplay
> FORGestureTrackDisplay is debug tool to displaying and tracking all kinds of gustures when user touch the screen.
## Usage
**first method ( Manual )**
> in this way, just the appdelegate.window can track gustures.
```objective-c
- (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions {
[self.window startTracking];
return YES;
}
```
**second method ( auto )**
> I highly recommend this way for auto track gestures in all windows.
```objective-c
@implementation NSObject (Runtime)
+ (void)swizzleInstanceMethodWithOriginSel:(SEL)oriSel swizzledSel:(SEL)swiSel {
Method originAddObserverMethod = class_getInstanceMethod(self, oriSel);
Method swizzledAddObserverMethod = class_getInstanceMethod(self, swiSel);
[self swizzleMethodWithOriginSel:oriSel oriMethod:originAddObserverMethod swizzledSel:swiSel swizzledMethod:swizzledAddObserverMethod class:self];
}
+ (void)swizzleMethodWithOriginSel:(SEL)oriSel
oriMethod:(Method)oriMethod
swizzledSel:(SEL)swizzledSel
swizzledMethod:(Method)swizzledMethod
class:(Class)cls {
BOOL didAddMethod = class_addMethod(cls, oriSel, method_getImplementation(swizzledMethod), method_getTypeEncoding(swizzledMethod));
if (didAddMethod) {
class_replaceMethod(cls, swizzledSel, method_getImplementation(oriMethod), method_getTypeEncoding(oriMethod));
} else {
method_exchangeImplementations(oriMethod, swizzledMethod);
}
}
@end
```
```objective-c
@implementation UIWindow (Runtime)
+ (void)load {
static dispatch_once_t onceToken;
dispatch_once(&onceToken, ^{
[self swizzleInstanceMethodWithOriginSel:@selector(becomeKeyWindow) swizzledSel:@selector(xy_becomeKeyWindow)];
[self swizzleInstanceMethodWithOriginSel:@selector(resignKeyWindow) swizzledSel:@selector(xy_resignKeyWindow)];
});
}
- (void)xy_becomeKeyWindow
{
[self xy_becomeKeyWindow];
[self startTracking];
}
- (void)xy_resignKeyWindow
{
[self xy_resignKeyWindow];
[self endTracking];
}
@end
```
