iOS,非视图类方法
2016-11-14 14:26 帅不过三秒 阅读(371) 评论(0) 编辑 收藏 举报isKindOfClass //判断是否是这个类或者这个类的子类的实例
例：
[mystring isKindOfClass:[NSString class]]
isMemberOfClass //判断是否是这个类的实例
例：
[mystring isMemberOfClass:[NSString class]]
//防止提示被键盘遮挡，直接展示到最高

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

//读取应用列表，看看有无权限获取;不越狱的机器没有这个权限来判定的

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。

NSPredicate类是用来定义逻辑条件约束的获取或内存中的过滤搜索。
//=、==：判断两个表达式是否相等，在谓词中=和==是相同的意思都是判断，而没有赋值这一说 NSNumber *testNumber = @123; NSPredicate *predicate = [NSPredicate predicateWithFormat:@"SELF = 123"]; if ([predicate evaluateWithObject:testNumber]) { NSLog(@"testString:%@", testNumber); }

//AND、&&：逻辑与，要求两个表达式的值都为YES时，结果才为YES。 NSArray *testArray = @[@1, @2, @3, @4, @5, @6]; NSPredicate *predicate = [NSPredicate predicateWithFormat:@"SELF > 2 && SELF < 5"]; NSArray *filterArray = [testArray filteredArrayUsingPredicate:predicate]; NSLog(@"filterArray:%@", filterArray);
