翻了下老邏輯，大約是記住了當(dāng)前調(diào)用過(guò)setFrame的UIStatusBar的實(shí)例，+load里dispatch_once保證了是首個(gè)調(diào)用者衷敌，避免抓到上層consumer手動(dòng)生成UIStatusBar被抓到

順便阿里社招要不要了解一下

+ (UIView *)statusBarInstance_ComOpenThreadOTScreenshotHelper
{
return statusBarInstance;
}

+ (void)load
{
static dispatch_once_t onceToken;
dispatch_once(&onceToken, ^{
Class statusBarClass = NSClassFromString(@"UIStatusBar");
[ComOpenThreadOTScreenshotHelperSwizzleHelper swizzClass:statusBarClass
selector:@selector(setFrame:)
selector:@selector(setFrameIntercept_ComOpenThreadOTScreenshotHelper:)];
[ComOpenThreadOTScreenshotHelperSwizzleHelper swizzClass:statusBarClass
selector:NSSelectorFromString(@"dealloc")
selector:@selector(deallocIntercept_ComOpenThreadOTScreenshotHelper)];
});
}

- (void)setFrameIntercept_ComOpenThreadOTScreenshotHelper:(CGRect)frame
{
[self setFrameIntercept_ComOpenThreadOTScreenshotHelper:frame];
statusBarInstance = self;
}

- (void)deallocIntercept_ComOpenThreadOTScreenshotHelper
{
statusBarInstance = nil;
[self deallocIntercept_ComOpenThreadOTScreenshotHelper];
}

關(guān)于代碼截屏帶狀態(tài)欄的問(wèn)題

昨天產(chǎn)品經(jīng)理告訴我，希望能實(shí)現(xiàn)仿網(wǎng)易嚴(yán)選那樣，可以捕捉到用戶的截屏操作肺樟，然后進(jìn)行截屏分享的小功能。在實(shí)現(xiàn)的過(guò)程中遇到的最大問(wèn)題就是截屏為什么沒(méi)有狀態(tài)欄逻淌？么伯？？然后各種查找卡儒，資料...
