层次:
实施例下面的代码。
#import "ViewController.h"
@interface ViewController()
@property (nonatomic) UITextField *textField1;
@property (nonatomic) UITextField *textField2;
@end
@implementation ViewController
- (void)viewDidLoad {
[super viewDidLoad];
UITextField *textField = [[UITextField alloc] initWithFrame:CGRectMake(0, 50, 50, 30)];
textField.borderStyle = UITextBorderStyleLine;
[self.view addSubview:textField];
self.textField1 = textField;
UITextField *textField2 = [[UITextField alloc] initWithFrame:CGRectMake(0, 100, 50, 30)];
textField2.borderStyle = UITextBorderStyleLine;
[self.view addSubview:textField2];
self.textField2 = textField2;
UIButton *button = [[UIButton alloc] initWithFrame:CGRectMake(0, 200, 50, 50)];
button.backgroundColor = [UIColor blueColor];
[button addTarget:self action:@selector(changeColor) forControlEvents:UIControlEventTouchUpInside];
[self.view addSubview:self.textField1];
[self.view addSubview:self.textField2];
[self.view addSubview:button];
}
- (void)changeColor
{
self.textField1.textColor = [UIColor greenColor];
self.textField2.textColor = [UIColor greenColor];
}
答
试试这个。
#import "ViewController.h"
@interface ViewController()
@property (nonatomic) UITextField *textField1;
@property (nonatomic) UITextField *textField2;
@end
@implementation ViewController
- (void)viewDidLoad {
[super viewDidLoad];
UITextField *textField = [[UITextField alloc] initWithFrame:CGRectMake(0, 50, 50, 30)];
textField.borderStyle = UITextBorderStyleLine;
[self.view addSubview:textField];
self.textField1 = textField;
UITextField *textField2 = [[UITextField alloc] initWithFrame:CGRectMake(0, 100, 50, 30)];
textField2.borderStyle = UITextBorderStyleLine;
[self.view addSubview:textField2];
self.textField2 = textField2;
UIButton *button = [[UIButton alloc] initWithFrame:CGRectMake(0, 200, 50, 50)];
button.backgroundColor = [UIColor blueColor];
[button addTarget:self action:@selector(changeColor) forControlEvents:UIControlEventTouchUpInside];
[self.view addSubview:self.textField1];
[self.view addSubview:self.textField2];
[self.view addSubview:button];
}
- (void)changeColor
{
self.textField1.textColor = [UIColor greenColor];
self.textField2.textColor = [UIColor greenColor];
self.textField1.text = self.textField1.text;
}
只是重置textfiled1文本。
你能澄清你的问题。究竟发生了什么? – rmaddy
我试图在轻按按钮时更改两个UITextFields的文本颜色。只有一个文本字段实际上会更改文本颜色。在图像中的检查员Xcode认为颜色是绿色的(R:0 G:1 B:0),但显示的内容仍然是黑色。我目前在应用商店中有一个应用正在做同样的事情,但在iOS 10中这不会发生。 –
是的,我也有这个问题。清爽的文字答案正在为我工作。 –
