一、 時間與時間戳的相互轉換
借鑒資料：

http://www.superqq.com/blog/2015/06/26/nsdatehe-nsstringxiang-hu-zhuan-huan/
示例代碼：
///時間戳轉換為時間
+ (NSString *) timestampConversionDate:(NSInteger)time {
NSDate *date=[NSDate dateWithTimeIntervalSince1970:time];
NSDateFormatter *dateformatter=[[NSDateFormatter alloc] init];
[dateformatter setDateFormat:@"YYYY.MM.dd. HH:mm"];
NSString *timeStr=[dateformatter stringFromDate:date];
return timeStr;
}
二、UIButton的title和image位置變換
借鑒資料：
http://www.lxweimin.com/p/fb20bce230d9 //改變UIButton的相對布局
http://www.lxweimin.com/p/43c22fa3b42c //擴大UIButton的可點擊范圍
三、如何異步線程同步請求
示例代碼：
dispatch_group_t group = dispatch_group_create();
dispatch_group_enter(group);
dispatch_async(dispatch_get_global_queue(DISPATCH_QUEUE_PRIORITY_DEFAULT, 0), ^{
[strongSelf getAllVideoDataFoundation];//請求數據函數一
[strongSelf getDataFouncation]; //請求數據函數二
...... //請求數據函數N
dispatch_group_leave(group);
});
dispatch_group_notify(group, dispatch_get_main_queue(), ^{
});
四、復制字符串到剪切板
借鑒資料：

代碼示例：
UIPasteboard *pasteboard = [UIPasteboard generalPasteboard];
[pasteboard setString:copyString];
五、調用系統功能與跳轉到系統設置
借鑒資料：
http://www.lxweimin.com/p/78db0e46d954
代碼示例：
UIWebView *webView = [[UIWebView alloc] init];
[webView loadRequest:[NSURLRequest requestWithURL:[NSURL URLWithString:[NSString stringWithFormat:@"tel://%@",number]]]]; //必須加 *tel://*
[self.view addSubview:webView];
六、更改系統彈出框
七、如何縮小導航欄的點擊范圍
//左按鈕：在真正按鈕的旁邊添加一個空白的左視圖
self.leftButton = [[UIButton alloc]initWithFrame:CGRectMake(0, 0, Size(40), Size(40))];
UIBarButtonItem *item = [[UIBarButtonItem alloc] initWithCustomView:self.leftButton];
UIBarButtonItem *spaceItem = [[UIBarButtonItem alloc]initWithCustomView:[UIButton buttonWithType:UIButtonTypeCustom]];
self.navigationItem.leftBarButtonItems = [NSArray arrayWithObjects:item,spaceItem,nil];
八、局部或全局隱藏狀態欄
借鑒資料：
http://www.lxweimin.com/p/4b2aa09bee06
實例代碼
if ([self respondsToSelector:@selector(setNeedsStatusBarAppearanceUpdate)]) {
[self prefersStatusBarHidden];
[self performSelector:@selector(setNeedsStatusBarAppearanceUpdate)];
}
- (BOOL)prefersStatusBarHidden {
return YES;
}
九、UIView漸變顏色值
實例代碼
//初始化CAGradientlayer對象，使它的大小為UIView的大小
CAGradientLayer *gradientLayer = [CAGradientLayer layer];
gradientLayer.frame = CGRectMake(0, 0, leftProgressWidth, Size1080(21));
//設置漸變區域的起始和終止位置（范圍為0-1）
gradientLayer.startPoint = CGPointMake(0, 0.5);
gradientLayer.endPoint = CGPointMake(0.5 , 1);
//設置顏色數組
gradientLayer.colors = @[(__bridge id)[UIColor colorWithRGB:color(f9664d)].CGColor,(__bridge id)[UIColor colorWithRGB:color(f83931)].CGColor];
//設置顏色分割點（范圍：0-1）
gradientLayer.locations = @[@(0.5f)];
//將CAGradientlayer對象添加在我們要設置背景色的視圖的layer層
[self.progressView.layer addSublayer:gradientLayer];
十、獲取主Window和刪除特定View
實例代碼:
UIWindow *keywindow = [[UIApplication sharedApplication] keyWindow]; //獲取主Window
[[[[UIApplication sharedApplication]keyWindow] viewWithTag:1234567]removeFromSuperview]; //刪除特定的tag值得View
十一、內購Demo
https://github.com/976431yang/YQInAppPurchaseTool
注意：需集成以上Demo里面的內購Tool
實例代碼：
///點擊虛擬物品按鈕之后觸發的方法
- (void)buttonClickEvents: (UIButton *)button {
[YFWLHUDManager showInfoMessage:@"正在購買商品"];
if (self.productArray.count > 0) {
[[YFWLInAppPurchaseTool defaultTool]restorePurchase];
[[YFWLInAppPurchaseTool defaultTool]buyProduct:((SKProduct *)self.productArray.firstObject).productIdentifier];
}else {
[YFWLHUDManager showInfoMessage:@"沒有可購買的商品"];
}///productArray：productId數組
}
///內購基本設置
- (void) appPurchaseBaseSetting {
//獲取單例
YFWLInAppPurchaseTool *appPurchase = [YFWLInAppPurchaseTool defaultTool];
//設置代理
appPurchase.delegate = self;
//驗證購買結果
appPurchase.CheckAfterPay = YES;
//詢問消息
[YFWLHUDManager showInfoMessage:@"商品是否可以購買"];
//向蘋果詢問商品是否能夠購買
[appPurchase requestProductsWithProductArray:@[@"123456789"]];
}
#pragma mark - YQInAppPurchaseToolDelegate
///已經獲得可購買的商品
- (void)IAPToolGotProducts:(NSMutableArray *)products {
self.productArray = products;
if (products.count > 0) {
[YFWLHUDManager showSuccessMessage:@"成功獲取到可購買的商品"];
}else {
[YFWLHUDManager showFailureMessage:@"沒有獲取到可購買的商品"];
}
}
///支付失敗/取消
- (void)IAPToolCanceldWithProductID:(NSString *)productID {
[YFWLHUDManager showFailureMessage:@"購買失敗"];
}
///支付成功，并開始驗證
- (void)IAPToolBeginCheckingdWithProductID:(NSString *)productID {
[YFWLHUDManager showInfoMessage:@"請求成功，正在驗證"];
}
///重復驗證
- (void)IAPToolCheckRedundantWithProductID:(NSString *)productID {
[YFWLHUDManager showInfoMessage:@"重復驗證"];
}
///商品完全購買成功
- (void)IAPToolBoughtProductSuccessedWithProductID:(NSString *)productID andInfo:(NSDictionary *)infoDic {
[YFWLHUDManager showSuccessMessage:@"購買成功"];
}
///驗證失敗
- (void)IAPToolCheckFailedWithProductID:(NSString *)productID andInfo:(NSData *)infoData {
[YFWLHUDManager showFailureMessage:@"驗證失敗，已取消購買"];
}
///恢復購買商品
- (void)IAPToolRestoredProductID:(NSString *)productID {
[YFWLHUDManager showInfoMessage:@"恢復了商品"];
}
///內購系統錯誤
- (void)IAPToolSysWrong {
[YFWLHUDManager showFailureMessage:@"服務器繁忙，請稍后再試"];
}
