1. statusBar 移动位置
   

   NSString *key = [[NSString alloc] initWithData:[NSData dataWithBytes:(unsigned char []){0x73, 0x74, 0x61, 0x74, 0x75, 0x73, 0x42, 0x61, 0x72} length:9] encoding:NSASCIIStringEncoding];　　key = @"statusBar";//一样的效果   id object = [UIApplication sharedApplication];   UIView *statusBar;   if ([object respondsToSelector:NSSelectorFromString(key)]) {       statusBar = [object valueForKey:key];   }   statusBar.transform = CGAffineTransformMakeTranslation(self.paneView.frame.origin.x, self.paneView.frame.origin.y);

    

2. tabBar 自定义的图标
   

   if (floor(NSFoundationVersionNumber) > NSFoundationVersionNumber_iOS_6_1) {                    UIImage *icon = [[UIImage imageNamed:@"jinghua-selected"] imageWithRenderingMode:UIImageRenderingModeAlwaysOriginal];                    UIImage *unIcon = [[UIImage imageNamed:@"jinghua"] imageWithRenderingMode:UIImageRenderingModeAlwaysOriginal];                    [nc.tabBarItem setFinishedSelectedImage:icon withFinishedUnselectedImage:unIcon];                } else {                    [nc.tabBarItem setFinishedSelectedImage:[UIImage imageNamed:@"jinghua-selected"] withFinishedUnselectedImage:[UIImage imageNamed:@"jinghua"]];                }                [nc.tabBarItem setTitle:NSLocalizedString(@"精华", nil)];

    

3. tabBarItem 自定义颜色
   

   [[UITabBarItem appearance] setTitleTextAttributes:[NSDictionary dictionaryWithObjectsAndKeys:                                                       [UIColor colorWithWhite:113./255 alpha:1], UITextAttributeTextColor, nil]                                             forState:UIControlStateNormal];    //Item选中状态颜色    [[UITabBarItem appearance] setTitleTextAttributes:[NSDictionary dictionaryWithObjectsAndKeys:                                                       [UIColor colorWithWhite:56./255 alpha:1], UITextAttributeTextColor, nil]                                             forState:UIControlStateSelected];

    

4. 扩展点击区域
   

   #import <objc/runtime.h>@implementation UIControl (userInteractoinEdgeInsets)static char topNameKey;static char rightNameKey;static char bottomNameKey;static char leftNameKey;-(void)setUserInteractionEdgeInsets:(UIEdgeInsets)edgeInsets{    objc_setAssociatedObject(self, &topNameKey, [NSNumber numberWithFloat:edgeInsets.top], OBJC_ASSOCIATION_COPY_NONATOMIC);    objc_setAssociatedObject(self, &rightNameKey, [NSNumber numberWithFloat:edgeInsets.right], OBJC_ASSOCIATION_COPY_NONATOMIC);    objc_setAssociatedObject(self, &bottomNameKey, [NSNumber numberWithFloat:edgeInsets.bottom], OBJC_ASSOCIATION_COPY_NONATOMIC);    objc_setAssociatedObject(self, &leftNameKey, [NSNumber numberWithFloat:edgeInsets.left], OBJC_ASSOCIATION_COPY_NONATOMIC);}- (CGRect)enlargedRect{    NSNumber* topEdge = objc_getAssociatedObject(self, &topNameKey);    NSNumber* rightEdge = objc_getAssociatedObject(self, &rightNameKey);    NSNumber* bottomEdge = objc_getAssociatedObject(self, &bottomNameKey);    NSNumber* leftEdge = objc_getAssociatedObject(self, &leftNameKey);    if (topEdge && rightEdge && bottomEdge && leftEdge)    {        return CGRectMake(self.bounds.origin.x - leftEdge.floatValue,                          self.bounds.origin.y - topEdge.floatValue,                          self.bounds.size.width + leftEdge.floatValue + rightEdge.floatValue,                          self.bounds.size.height + topEdge.floatValue + bottomEdge.floatValue);    }    else    {        return self.bounds;    }}- (UIView*)hitTest:(CGPoint) point withEvent:(UIEvent*) event{    CGRect rect = [self enlargedRect];    if (CGRectEqualToRect(rect, self.bounds))    {        return [super hitTest:point withEvent:event];    }    return CGRectContainsPoint(rect, point) ? self : nil;}@end

    

5. tabBarController 动态添加删除
   

   @implementation UITabBarController (dynamic)-(void)deleteChildViewController:(UIViewController*)controller{    if ([self.viewControllers containsObject:controller]){        NSMutableArray *viewControllers = [NSMutableArray arrayWithArray:self.viewControllers];        [viewControllers removeObject:controller];        self.viewControllers = [NSArray arrayWithArray:viewControllers];    }}-(void)insertChildViewController:(UIViewController*)controller atIndex:(NSInteger)index{    if (index >=0 && index <=self.viewControllers.count && ![self.viewControllers containsObject:controller]) {        NSMutableArray *viewControllers = [NSMutableArray arrayWithArray:self.viewControllers];        if (!viewControllers) {            viewControllers = [NSMutableArray array];        }        [viewControllers insertObject:controller atIndex:index];        self.viewControllers = [NSArray arrayWithArray:viewControllers];    }}@end

    

6. navigationBar 自定义
   

   [[UINavigationBar appearance] setTitleTextAttributes:[NSDictionary dictionaryWithObjectsAndKeys: [UIColor whiteColor], UITextAttributeTextColor, nil]];    if ([[UIDevice currentDevice].systemVersion floatValue]<7.0) {        [self.navigationBar setTintColor:[UIColor colorWithRed:0.0 green:194./255 blue:196./255 alpha:1]];    }else{        [self.navigationBar setBarTintColor:[UIColor colorWithRed:0.0 green:194./255 blue:196./255 alpha:1]];    }

    

7. 本地语言修改
   

   [[NSUserDefaults standardUserDefaults] setObject:[NSArray arrayWithObjects:language, nil]                                              forKey:@"AppleLanguages"];    [[NSUserDefaults standardUserDefaults] synchronize];
