注:我可以通过在我的barbutton和barbutton2方法中将leftbarbuttonitem切换到rightbarbutton项目来实现此目的。我只是想知道为什么它不能正常工作!rightbarbuttonitem没有显示出来?
出于某种奇怪的原因,我的左巴钮扣图案正在显示,但我的右巴钮扣图案永远不会弹出!这里是我的代码
-(void)barButton {
image = [UIImage imageNamed:@"BBut.png"];
UIButton *button = [UIButton buttonWithType:UIButtonTypeCustom];
[button setBackgroundImage: [image stretchableImageWithLeftCapWidth:7.0 topCapHeight:0.0] forState:UIControlStateNormal];
[button setBackgroundImage: [[UIImage imageNamed: @"BBut.png"] stretchableImageWithLeftCapWidth:7.0 topCapHeight:0.0] forState:UIControlStateHighlighted];
[button addTarget:self action:@selector(showlocations:) forControlEvents:UIControlEventTouchUpInside];
button.frame= CGRectMake(3.0, 0.0, image.size.width+1, image.size.height+0);
UIView *v=[[UIView alloc] initWithFrame:CGRectMake(3.0, 0.0, image.size.width+1, image.size.height) ];
[v addSubview:button];
UIBarButtonItem *modal = [[UIBarButtonItem alloc] initWithCustomView:v];
self.navigation.leftBarButtonItem = modal;
-(void)barButton2 {
image2 = [UIImage imageNamed:@"Refresh.png"];
UIButton *button2 = [UIButton buttonWithType:UIButtonTypeCustom];
[button2 setBackgroundImage: [image2 stretchableImageWithLeftCapWidth:0.0 topCapHeight:0.0] forState:UIControlStateNormal];
[button2 setBackgroundImage: [[UIImage imageNamed: @"Refresh.png"] stretchableImageWithLeftCapWidth:0.0 topCapHeight:0.0] forState:UIControlStateHighlighted];
// [button2 addTarget:self action:@selector(viewDidLoad) forControlEvents:UIControlEventTouchUpInside];
button2.frame= CGRectMake(281.0, 5.0, image2.size.width, image2.size.height);
UIView *v2=[[UIView alloc] initWithFrame:CGRectMake(281.0, 5.0, image2.size.width, image2.size.height) ];
[v2 addSubview:button2];
UIBarButtonItem *refresh = [[UIBarButtonItem alloc] initWithCustomView:v2]; self.navigation.rightBarButtonItem = refresh;
NSLog(@"THE ACTION HAS BEEN RECIEVED!"); }
在我viewDidLoad方法中,我有这样的:
[self barButton2];
[self barButton];
行动确实经历,我也接受我的NSLog的方法。有谁知道为什么会发生这种情况?左栏按钮总是显示出来,如果我将第一个barbutton更改为rightbarbuttonitem,并将barbutton2更改为leftbarbutton项,然后更改CGRect坐标系,它就可以工作,这就是我现在正在使用它来使其工作,但为什么会发生这种情况?提前致谢。
谢谢!就是这样!我不知道为什么我明白它会在x = 281的原始视图中。这让我有点疯狂!再次感谢你! – sridvijay 2012-07-06 23:33:04
