变化uitabbar背景颜色

Question

我写这个代码，但警告显示“insertSubview” 可能不会响应

- (void)viewDidLoad { 

    [super viewDidLoad]; 

    CGRect frame = CGRectMake(0, 0, 480, 49); 

    UIView *v = [[UIView alloc] initWithFrame:frame]; 

    UIImage *i = [UIImage imageNamed:@"GO-21-TabBarColorx49.png"]; 

    UIColor *c = [[UIColor alloc] initWithPatternImage:i]; 

    v.backgroundColor = c; 

    [c release]; 

    [[self tabBar] addSubview:v]; 

    [v release]; 

} 

Answer 1

你尝试

[[self tabBar] insertSubview:v atIndex:0]; 

而不是addSubview:
