在繼承UITabBarController的類中實現(xiàn)以下方法

-(void)viewWillLayoutSubviews{

[superviewWillLayoutSubviews];

for(UIView*childinself.tabBar.subviews) {

if([childisKindOfClass:NSClassFromString(@"UITabBarButton")]) {

[childremoveFromSuperview];

}

}

}

- (void)viewWillAppear:(BOOL)animated

{

//刪除系統(tǒng)自動生成的UITabBarButton

for(UIView*childinself.tabBar.subviews) {

if([childisKindOfClass:[UIControlclass]]) {

[childremoveFromSuperview];

}

}

[superviewWillAppear:animated];

}
