tarBarItem圖標在iPhone上被切掉了

Question

tabBarController = [[UITabBarController alloc] initWithNibName:nil bundle:nil];   
tabBarController.delegate = self; 

UINavigationController *searchNav = [[[UINavigationController alloc] initWithRootViewController:search] autorelease]; 
searchNav.navigationBar.barStyle = UIBarStyleBlack; 

[searchNav.tabBarItem initWithTitle:@"Search" image:[UIImage imageNamed:@"icn_find.png"] tag:0]; 


SettingsView *settings = [[[SettingsView alloc] initWithNibName:@"SettingsView" bundle:nil] autorelease]; 
settings.delegate = self; 
UINavigationController *nav2 = [[[UINavigationController alloc] initWithRootViewController:settings] autorelease]; 
nav2.navigationBar.barStyle = UIBarStyleBlack; 
[nav2.tabBarItem initWithTitle:@"Settings" image:[UIImage imageNamed:@"icn_Settings.png"] tag:1]; 

    tabBarController.viewControllers = [NSArray arrayWithObjects: searchNav, nav2, nil]; 

我遇到的問題是tabbaritem的圖標圖像被砍掉了。我如何使它適合整個圖標？

我認爲你必須調整你的圖標大小約30x30大小（official reference）。

你也可以以編程方式調整你的UIImage的大小，但對於這種類型的固定圖像，用手調整大小會更明智。
