-(void)loadView
{
[super loadView];

注意这里:一定要先[super loadView];

不然下边对self.view访问会出现死循环.

在这里生成self.view

下边就可以对他进行设置了

    UIView *new= [[UIView alloc] initWithFrame:CGRectMake(0, 0, 320, 568)];
    UILabel*lable = [[UILabel alloc] initWithFrame:CGRectMake(30, 30, 200, 50)];
    lable.layer.cornerRadius = 5;
    lable.layer.masksToBounds = YES;
    lable.backgroundColor = [UIColor redColor];
    lable.text = @"lable";
    [self.view addSubview:lable];

    UITextField*tf = [[UITextField alloc] initWithFrame:CGRectMake(30, 120, 200, 30)];
    tf.backgroundColor = [UIColor greenColor];
    tf.placeholder = @"enter here";
    tf.text =@"tf";
    [self.view addSubview:tf];
    tf.delegate = self;
    [tf release];
