  • iOS textField placeholder 信息上浮

    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;
        
    }
    
    
    
    @end
