自定义UIButton的时候遇到的小问题

出现问题的代码如下：

//选择按钮
UIButton *performerButton = [UIButton buttonWithType:UIButtonTypeCustom];
[performerButton setFrame:CGRectMake(tip.frame.size.width+10.0, y+11.0, 35.0, 25.0)];
[performerButton addTarget:self
                    action:@selector(setTeleplayType:)
          forControlEvents:UIControlEventTouchUpInside];
[self.scrollView addSubview:performerButton];
[performerButton setTitle:@"演员" forState:UIControlStateNormal];
[performerButton setTitleColor:[UIColor redColor] forState:UIControlStateNormal];

结果是看不到你添加的标题。

问题的关键是如何解决的，呵呵，蠢死我了，其实就是自己设计的button的宽度太小了，没有将字体显示出来.

结果的代码如下修改就好：

//选择按钮
UIButton *performerButton = [UIButton buttonWithType:UIButtonTypeCustom];
[performerButton setFrame:CGRectMake(tip.frame.size.width+10.0, y+11.0, 45.0, 25.0)];
[performerButton addTarget:self
                    action:@selector(setTeleplayType:)
          forControlEvents:UIControlEventTouchUpInside];
[self.scrollView addSubview:performerButton];
[performerButton setTitle:@"演员" forState:UIControlStateNormal];
[performerButton setTitleColor:[UIColor redColor] forState:UIControlStateNormal];
