ios – 如何设置navigationItem titleView的按钮？

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];
