问题描述
//TabBarController code:
self.delegate=self;
self.tabBarController.tabBar.delegate=self;
CGRect viewFrame=self.tabBar.frame;
viewFrame.origin.y -=0;![enter image description here][1]
viewFrame.origin.x -=0;
viewFrame.size.height=30;
self.tabBar.frame=viewFrame;
firstViewController = [[FirstViewController alloc] initWithNibName:nil bundle:NULL];
secondViewController = [[SecondViewController alloc] initWithNibName:nil bundle:NULL];
NSArray *twoViewControllers = [[NSArray alloc] initWithObjects:
self.firstViewController, self.secondViewController, nil];
self.viewControllers=twoViewControllers;
// ====================================================
//
// FirstViewController code in initWithNibName:
//
// To set the title of the first tabbar item:
- (id)initWithNibName:(NSString *)nibNameOrNil bundle:(NSBundle *)nibBundleOrNil
{
self = [super initWithNibName:nibNameOrNil bundle:nibBundleOrNil];
if (self) {
self.title = @"Article view";
NSLog(@"count = %d",[self.tabBarController.tabBar.items count]);
}
return self;
}
//如何将第一个标签栏项目标题文章视图设为中心没有添加任何//图像到tabbaritem?
//How can i make the first tabbar item title "Article View" to the Center without adding any //image to the tabbaritem ?
//类似于下面的tabbar项目截图。
// similar to the below tabbar items screenshot.

推荐答案
替换 initWithNibName
方法
- (id)initWithNibName:(NSString *)nibNameOrNil bundle:(NSBundle *)nibBundleOrNil
{
self = [super initWithNibName:nibNameOrNil bundle:nibBundleOrNil];
if (self) {
self.title = @"Article view";
self.tabBarItem.imageInsets = UIEdgeInsetsMake(5, 0, -5, 0);
NSLog(@"count = %d",[self.tabBarController.tabBar.items count]);
}
return self;
}
self.tabBarItem.imageInsets = UIEdgeInsetsMake(5, 0,-5,0);
此行此处以下列方式调整tabBarItem的图像位置:
self.tabBarItem.imageInsets = UIEdgeInsetsMake(5, 0, -5, 0);
this line here adjusts the position of the image for the tabBarItem in the manner :
从
默认位置向x方向'+5'和y方向'-5'移动图像。
Shift the image in x-direction '+5' and in y-direction '-5' from the default position.
玩 UIEdgeInsetsMake
并玩得开心。干杯。
