iOS实现选项卡效果的方法

先来看看实现效果：

控件是如何使用的

添加LMJTabDelegate代理

LMJTab * tab = [[LMJTab alloc] initWithframe:CGRectMake(10, 50, 300, 30) lineWidth:1 lineColor:[UIColor blackColor]];
[tab setItemsWithTitle:[NSArray arrayWithObjects:@"选项一",@"选项二",@"选项三", nil] normalItemColor:[UIColor whiteColor] selectItemColor:[UIColor blackColor] normalTitleColor:[UIColor blackColor] selectTitleColor:[UIColor whiteColor] titleTextSize:15 selectItemNumber:1];
tab.delegate   = self;
tab.layer.cornerRadius = 5.0;
[self.view addSubview:tab];

代理函数

-(void)tab:(LMJTab *)tab didSelectedItemNumber:(NSInteger)number{
 NSLog(@"CLICKED:%ld",number);
}

LMJTab介绍：

@protocol LMJTabDelegate 

-(void)tab:(LMJTab *)tab didSelectedItemNumber:(NSInteger)number;

@end

@interface LMJTab : UIView

@property (nonatomic,assign) iddelegate;


-(id)initWithframe:(CGRect)frame lineWidth:(CGFloat)lineWidth lineColor:(UIColor *)lineColor;


-(void)setItemsWithTitle:(NSArray *)titles normalItemColor:(UIColor *)nItemColor selectItemColor:(UIColor *)sItemColor normalTitleColor:(UIColor *)nTitleColor selectTitleColor:(UIColor *)sTitleColor titleTextSize:(CGFloat)size selectItemNumber:(NSInteger)number;

@end
