本文介绍了一种textFieldplaceholder提示信息上浮的效果实现方法。通过简单的继承方式，当输入框中有文字时，placeholder信息会自动浮动到左上角。文中提供了具体的代码示例，包括如何设置不同状态下的颜色。

textField placeholder 提示信息上浮

当输入框有文的时候 placeholder 信息就浮动到左上角。

只要继承就行，使用非常简单。

tintFloatField

代码调用非常简单

#import "RPFloatingPlaceholderTextField.h"
#import "RPFloatingPlaceholderTextView.h"

@interface ViewController ()
@property (weak, nonatomic) IBOutlet RPFloatingPlaceholderTextField *titleField;
@property (weak, nonatomic) IBOutlet RPFloatingPlaceholderTextField *detailField;

@property (weak, nonatomic) IBOutlet RPFloatingPlaceholderTextField *localField;
@property (weak, nonatomic) IBOutlet RPFloatingPlaceholderTextField *cityField;

@property (weak, nonatomic) IBOutlet RPFloatingPlaceholderTextView *describeTextView;

@end

@implementation ViewController

- (void)viewDidLoad {
    [super viewDidLoad];
    // Do any additional setup after loading the view, typically from a nib.
    
    self.titleField.floatingLabelActiveTextColor = [UIColor redColor];
    self.titleField.floatingLabelInactiveTextColor = [UIColor blueColor];
    
    self.detailField.floatingLabelActiveTextColor = [UIColor redColor];
    self.detailField.floatingLabelInactiveTextColor = [UIColor blueColor];
    
    
    
    self.localField.floatingLabelActiveTextColor = [UIColor redColor];
    self.localField.floatingLabelInactiveTextColor = [UIColor blueColor];
    
    self.cityField.floatingLabelActiveTextColor = [UIColor redColor];
    self.cityField.floatingLabelInactiveTextColor = [UIColor blueColor];

    
    
    self.describeTextView.placeholder = @"describe";
    self.describeTextView.floatingLabelActiveTextColor = [UIColor redColor];
    self.describeTextView.floatingLabelInactiveTextColor = [UIColor blueColor];
    
    self.describeTextView.layer.borderColor = [UIColor blackColor].CGColor;
    self.describeTextView.layer.borderWidth = 1;
    
}
