Ios UIButton中的按钮标题意外更改

我用以下代码创建了一个

ui按钮

：

applyButton= [[UIButton alloc] initWithFrame:CGRectMake(75, 636, 150, 50)];
[applyButton titleColorForState:UIControlStateNormal];
[applyButton setTitle:@"MyTitle" forState:UIControlStateNormal];
 applyButton.titleLabel.textColor=[UIColor lightGrayColor];
[[applyButton layer] setBorderWidth:2.0f];
[[applyButton layer] setBorderColor:[[UIColor lightGrayColor] CGColor]];

applyButton.layer.cornerRadius = 10;
[applyButton addTarget:self action:@selector(saveSettingsToNSUser:) forControlEvents:UIControlEventTouchUpInside];
[self.view addSubview:applyButton];

按钮最初以浅灰色显示“MyTitle”。

但当我按下它时，标题颜色变为白色，并调用“saveSettingsToNSUser”函数。函数“saveSettingsToNSUser”中没有影响按钮的内容。我不明白发生了什么事。我遗漏了什么吗？

您应该使用

设置标题颜色：forState:

来设置标题标签的颜色

applyButton= [[UIButton alloc] initWithFrame:CGRectMake(75, 636, 150, 50)];
//set title
[applyButton setTitle:@"MyTitle" forState:UIControlStateHighlighted];
[applyButton titleColorForState:UIControlStateNormal];
[applyButton setTitle:@"MyTitle" forState:UIControlStateNormal];
 applyButton.titleLabel.textColor=[UIColor lightGrayColor];
[[applyButton layer] setBorderWidth:2.0f];
[[applyButton layer] setBorderColor:[[UIColor lightGrayColor] CGColor]];

applyButton.layer.cornerRadius = 10;
[applyButton addTarget:self action:@selector(saveSettingsToNSUser:)   forControlEvents:UIControlEventTouchUpInside];
[self.view addSubview:applyButton];

[applyButton setTitleColor: [UIColor lightGrayColor] forState: UIControlStateNormal];
