button.transform = CGAffineTransformMakeScale(-1.0, 1.0);
button.titleLabel.transform = CGAffineTransformMakeScale(-1.0, 1.0);
button.imageView.transform = CGAffineTransformMakeScale(-1.0, 1.0);

技巧2：設(shè)置導(dǎo)航欄透明，title與BarButtonItem不透明

[self.navigationController.navigationBar setBackgroundImage:[UIImage new] forBarMetrics:UIBarMetricsDefault];

self.navigationController.navigationBar.translucent = YES;

技巧3：設(shè)置導(dǎo)航欄無邊框

self.navigationController.navigationBar.shadowImage = [UIImage new];

技巧4: 隨視圖的滾動導(dǎo)航欄隱藏與顯示（一句代碼即可）

self.navigationController.hidesBarsOnSwipe = Yes;

技巧5：簡單好用的獲取當(dāng)前時間戳

 //時間戳
 time_t now;
 time(&now);
 NSLog(@"---%ld",now);

技巧6：只設(shè)置UIView的左上角和右上角的圓角 (四個圓角位置都可以選擇)

 UIView *blueView = [[UIView alloc] initWithFrame:CGRectMake(100, 100, 200, 100)];
 blueView.backgroundColor = [UIColor blueColor];
 [self.view addSubview: blueView]; 
 /*設(shè)置圓角位置的枚舉參數(shù)
  UIRectCornerTopLeft  = 1 << 0,
  UIRectCornerTopRight = 1 << 1,
  UIRectCornerBottomLeft = 1 << 2,
  UIRectCornerBottomRight = 1 << 3,
  UIRectCornerAllCorners = ~0UL
  */
 UIBezierPath *maskPath = [UIBezierPath bezierPathWithRoundedRect:blueView.bounds byRoundingCorners:(UIRectCornerTopLeft|UIRectCornerTopRight) cornerRadii:CGSizeMake(20.0, 20.0)];
 CAShapeLayer *maskLayer = [CAShapeLayer layer];
 maskLayer.frame = blueView.bounds;
 maskLayer.path = maskPath.CGPath;
 blueView.layer.mask = maskLayer;

技巧7: 加載UIWebView后禁止用戶復(fù)制剪切

// 控制器實(shí)現(xiàn)此方法
- (BOOL)canPerformAction:(SEL)action withSender:(id)sender
{
 if (action == @selector(copy:) ||
  action == @selector(paste:)||
  action == @selector(cut:))
 {
  return NO;
 }
 return [super canPerformAction:action withSender:sender];
}

技巧8：跳轉(zhuǎn)控制器隱藏tabbar一個一勞永逸的方法

// 創(chuàng)建一個Nav基類 重寫pushViewController:方法 如下：
-(void)pushViewController:(UIViewController *)viewController animated:(BOOL)animated {

 viewController.hidesBottomBarWhenPushed = YES;

 [super pushViewController:viewController animated:animated];

}
