在ios中cell属于常用控件之一，在cell中设置按钮，该如何跳转其他VC那？
\ 如下:
//设置view的类扩展(extension)UIViewController
#import <UIKit/UIKit.h>
@interface UIView (UIViewController)
- (UIViewController *)viewController;
@end
#import "UIView+UIViewController.h"
@implementation UIView (UIViewController)
- (UIViewController *)viewController {
//通过响应者链，取得此视图所在的视图控制器
UIResponder *next = self.nextResponder;
do {
//判断响应者对象是否是视图控制器类型
if ([next isKindOfClass:[UIViewController class]]) {
return (UIViewController *)next;
}
next = next.nextResponder;
}while(next != nil);
return nil;
}
@end
实际应用中如下写法即可：
@implementation TestTableViewCell
- (instancetype)initWithStyle:(UITableViewCellStyle)style reuseIdentifier:(NSString *)reuseIdentifier{
if (self = [super initWithStyle:style reuseIdentifier:reuseIdentifier]) {
[self setUI];
}
return self;
}
- (void)setUI{
UIButton *btn = [[UIButton alloc] initWithFrame:CGRectMake(10, 10, 200, 100)];
btn.backgroundColor = [UIColor blueColor];
[btn addTarget:self action:@selector(btnClicked:) forControlEvents:UIControlEventTouchUpInside];
[self.contentView addSubview:self.recordButton];
}
//只需self.viewController就可找到navigationController进行push
- (void)btnClicked:(UIButton *)sender{
Test2ViewController *vc = [[Test2ViewController alloc]init];
[self.viewController.navigationController pushViewController:vc animated:YES];
}
欢迎互相学习Github
