我有一个UITextField子类,我已经覆盖了一些方法(参见下面的代码).问题是,当我输入它并且文本达到严格边距时,它将不再显示我正在键入的内容.在视图调试模式中,我看到UIFieldEditor比文本提交的要宽得多.
这是UITextFiled子类代码：
- (instancetype)init
{
self = [super init];
if (self) {
self.edgeInsets = UIEdgeInsetsMake(7,10,15);
}
return self;
}
- (id)initWithFrame:(CGRect)frame{
self = [super initWithFrame:frame];
if (self) {
self.edgeInsets = UIEdgeInsetsMake(7,15);
}
return self;
}
-(id)initWithCoder:(NSCoder *)aDecoder{
self = [super initWithCoder:aDecoder];
if(self){
self.edgeInsets = UIEdgeInsetsMake(7,15);
}
return self;
}
- (CGRect)textRectForBounds:(CGRect)bounds {
return [super textRectForBounds:UIEdgeInsetsInsetRect(bounds,self.edgeInsets)];
}
- (CGRect)editingRectForBounds:(CGRect)bounds {
return [super editingRectForBounds:UIEdgeInsetsInsetRect(bounds,self.edgeInsets)];
}
这是我使用这个类的代码：
// alloc / init
_myTextField.delegate = self;
_myTextField.backgroundColor = [UIColor whiteColor];
_myTextField.layer.masksToBounds = YES;
_myTextField.layer.cornerRadius = 3.0;
_myTextField.returnKeyType = UIReturnKeyDone;
_myTextField.clearButtonMode = UITextFieldviewmodeWhileEditing;
_myTextField.autocapitalizationType = UITextAutocapitalizationTypeWords;
_myTextField.autocorrectionType = UITextAutocorrectionTypeNo;
_myTextField.hidden = YES;
_tfButton = [UIButton buttonWithType:UIButtonTypeSystem];
[_tfButton setImage:[UIImage imageNamed:@"ic_edit"] forState:UIControlStateNormal];
[self fs_addSubview:_tfButton];
[_tfButton constrainWidth:22.];
[_tfButton setTintColor:[UIColor greenColor]];
[_tfButton constrainHeight:22.];
[_tfButton constrainToRightOfView:_myTextField margin:-25.0];
[_tfButton constrainEqualCenterYWithView:_myTextField offset:0.0];
[_tfButton setUserInteractionEnabled:NO];
UIView *leftView = [[UIView alloc] initWithFrame:CGRectMake(0,5,5)];
_myTextField.leftView = leftView;
_myTextField.leftviewmode = UITextFieldviewmodeAlways;
当用户在此文本字段中键入大字符串时,如何让文本在左侧滚动？
