功能介绍

1. 统计每个界面的FPS的变化曲线

---

如何使用

• 将HCFPS目录下的Classes加入到工程中
• 默认是DEBUG模式下会去统计界面的FPS信息，如果想却掉这个限制，在下面的代码将条件编译的去掉

@implementation UIViewController (FPS)+(void)load
{#if DEBUG
static dispatch_once_t onceToken;
dispatch_once(&onceToken, ^{
Method didLoadMethod =class_getInstanceMethod(self,@selector(viewDidLoad));
Method fps_didLoadMethod =class_getInstanceMethod(self,@selector(fps_viewDidLoad));
method_exchangeImplementations(didLoadMethod, fps_didLoadMethod);
Method viewWillDisappearMethod=class_getInstanceMethod(self,@selector(viewWillDisappear:));
Method fps_viewWillDisappearMethod=class_getInstanceMethod(self,@selector(fps_viewWillDisappear:));
method_exchangeImplementations(viewWillDisappearMethod, fps_viewWillDisappearMethod);
});
#endif}

• 有些界面你不想去统计FPS信息，也可以设置忽略一些类的实例不统计

+(void)initialize{
static dispatch_once_t onceToken;
dispatch_once(&onceToken, ^{
_ignoreControllers = @[@"UICompatibilityInputViewController",
@"UIAlertController",
@"UISplitViewController",
@"UIInputWindowController"];
});
}
