自定义toolbar

自定义tabbar类似新浪微博一样，转发/点赞/评论

#import <UIKit/UIKit.h>typedef enum {    HMComposeToolbarleft, // 转发    HMComposeToolbarButtonTypemodel, // 点赞    HMComposeToolbarButtonTyperight // 评论} HMComposeToolbarButtonType;@class HMStatusToolbar;@protocol HMStatusToolbarDelegate <NSObject>@optional- (void)composeTool:(HMStatusToolbar *)toolbar didClickedButton:(HMComposeToolbarButtonType)buttonType;@end@interface HMStatusToolbar : UIImageView@property (nonatomic, weak) id<HMStatusToolbarDelegate> delegate;@end

自定义tabbar完成，字需要从控制器中调用就可以了

HMStatusToolbar *toolbar = [[HMStatusToolbar alloc]init];    toolbar.frame =CGRectMake(0, 300, self.view.bounds.size.width, 40);    toolbar.delegate = self;    [self.view addSubview:toolbar];

实现代理方法

- (void)composeTool:(HMStatusToolbar *)toolbar didClickedButton:(HMComposeToolbarButtonType)buttonType；
