判断类的实例

例：[mystring isKindOfClass:[NSString class]]

//防止提示被键盘遮挡，直接展示到最高
UIWindow *win=[[UIApplication sharedApplication].windows objectAtIndex:([UIApplication sharedApplication].windows.count-1)];

获取当前app是否活跃
//当前app是活跃的在前台
[UIApplication sharedApplication].applicationState == UIApplicationStateActive
//当前app在后台
[UIApplication sharedApplication].applicationState ==UIApplicationStateBackground
允许所有请求(加下面代码加到Appdelegate头部，整个app就允许所有请求)

iOS注释方法或属性废弃或不可用
废弃
-(void)oldFunction __attribute__((deprecated("使用新API")));
@property(nonatomic,strong) NSString *oldString __attribute__((deprecated("使用新属性")));
不可用
-(void)oldFunction __attribute__((unavailable("使用新API")));
@property(nonatomic,strong) NSString *oldString __attribute__((unavailable("使用新属性")));
系统宏废弃方法
NS_AVAILABLE_IOS(5_0)，告诉我们这个方法可以在iOS5.0及以后的版本中使用。如果我们在比指定版本更老的版本中调用这个方法，就会引起崩溃。
NS_AVAILABLE(5.0,2.0),这里表示这个方法随Mac OS 5.0和iOS 2.0及以后的版本中使用
NS_DEPRECATED_IOS(2_0, 6_0,"使用新API"),这个宏中有两个版本号。前面一个表明了这个方法被引入时的iOS版本，后面一个表明它被废弃时的iOS版本。被废弃并不是指这个方法就不存在了，只是意味着我们应当开始考虑将相关代码迁移到新的API上去了。
NS_DEPRECATED(10_0, 10_6, 2_0, 4_0,"使用新api"),这里表示这个方法随Mac OS 10.0和iOS 2.0被引入，在Mac OS 10.6和iOS 4.0后被废弃。
