FPSOfViewController
[TOC]
功能介绍
- 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"];
});
}
