FORGestureTrackDisplay 是一个调试工具，用于在用户触摸屏幕时显示和跟踪所有类型的手势。
使用方法
第一种方法（手动）
这种方式，只有 appdelegate.window 可以跟踪手势。
- (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions {
[self.window startTracking];
return YES;
}第二种方法（自动）
我强烈推荐这种方式来自动跟踪所有窗口中的手势。
@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@implementation UIWindow (Runtime)

static dispatch_once_t onceToken;
dispatch_once(&onceToken, ^{

[self swizzleInstanceMethodWithOriginSel:@selector(resignKeyWindow) swizzledSel:@selector(xy_resignKeyWindow)];
});
}
- (void)xy_becomeKeyWindow
{
[self xy_becomeKeyWindow];
[self startTracking];
}
- (void)xy_resignKeyWindow
{
[self xy_resignKeyWindow];
[self endTracking];
}
