这是我的代码:

CGFloat components[8];//[8];// = {  0.6, 0.6, 0.6, 0.5, 0.4, 0.4, 0.4, 0.5 };
if ([appDelegate.graphType isEqualToString:@"response"])
{
    CGFloat components[8] = {  0.2, 0.2, 0.2, 0.5, 0.5, 0.5, 0.5, 0.5 };
}
else 
{
    if ([appDelegate.graphType isEqualToString:@"uptime"])
    {
        CGFloat components[8] = {  0.694, 0.855, 0.961, 0.5, 0.188, 0.588, 0.906, 0.5 };
    }
    else
    {
        CGFloat components[8] = {  0.694, 0.855, 0.961, 0.5, 0.188, 0.588, 0.906, 0.5 };
    }
}

所以基本上,我想根据不同的图形类型绘制不同的渐变.但是,xCode向我显示来自if/else语句的CGFloat组件[8]未使用并忽略其值.有什么想法是什么问题

有人知道如何消除围绕按下的动作栏菜单项的恼人的蓝色光芒吗？

我的应用程序崩溃了 [NSThread detachNewThreadSelector: @selector(getJSON:) toTarget:self withObject:nil];

以下是getJSON函数的外观: - (void)getJSON: (NSDate *)startTime endTime:(NSDate *)endTime;

这有什么问题？

图片价值超过千言万语:)

这是代码:

// Initialization code
        UIView *myContentView = self.contentView;
        UIImage *image = [UIImage imageNamed: @"bg_top.png"];
        UIImageView *imageview = [[UIImageView alloc] initWithImage: image];
        self.backgroundView = imageview;
        [imageview release];
        self.label = [self newLabelWithPrimaryColor:[UIColor blackColor] selectedColor:[UIColor redColor] fontSize:15.0 bold:YES]; 
        self.label.textAlignment = UITextAlignmentLeft; 
        [myContentView addSubview:self.label];
        [self.label release];


    self.textField = [[UITextField alloc] init];
    [self.textField setTextColor:[UIColor grayColor]];
    self.textField.font = [UIFont systemFontOfSize:13.0];
    //self.textField.secureTextEntry = YES;
    [self.textField setKeyboardType:UIKeyboardTypeEmailAddress];
    myContentView.backgroundColor = [UIColor clearColor];
    [myContentView addSubview:self.textField];
    [self.textField release];
