我想以编程方式设置navigationItem.titleView的按钮.
我尝试使用以下代码,但没有成功;
UIBarButtonItem *navigationTitleButton = [[UIBarButtonItem alloc] initWithTitle:@"Custom" style:UIBarButtonItemStyleBordered target:self action:@selector(backToHOmePage)]; navigationTitleButton.image = [UIImage imageNamed:@"title.png"]; self.navigationItem.titleView = navigationTitleButton;
Warnng说：从’UIBarButtonItem * __ strong’分配给’UIView *’的指针类型不兼容
解决方法
尝试使用此代码,看看它是否适合您
UIView * container = [[UIView alloc]initWithFrame:CGRectZero]; UIButton * button = [[UIButton alloc]initWithFrame:CGRectZero]; [button addTarget:self action:@selector(backToHOmePage) forControlEvents:UIControlEventTouchUpInside]; [button setImage:[UIImage imageNamed:@"clanak_default.png"] forState:UIControlStateNormal]; [button sizeToFit]; [container addSubview:button]; [button release]; [container sizeToFit]; self.navigationItem.titleView = container; [container release];
