[英]How to vertically align a UILabel used as a leftView in a UITextField with the textField's text?
我使用UILabel
作為UITextField
的leftView
。 問題是textField的文本高於標簽的文本。
這是我到目前為止使用的代碼
UILabel *startsWith = [[UILabel alloc] init];
startsWith.font = [UIFont systemFontOfSize:14];
startsWith.textColor = [UIColor blackColor];
startsWith.backgroundColor = [UIColor clearColor];
startsWith.text = @"Text";
[startsWith sizeToFit];
self.textField.leftViewMode = UITextFieldViewModeAlways;
self.textField.leftView = startsWith;
我試過稍微改變標簽的框架,但是沒有用...
如何對齊兩個文本?
您可以創建一個容器視圖,在其中將UILabel
向上放置1px。
UIView * v = [[UIView alloc] init];
v.backgroundColor = [UIColor clearColor];
UILabel *startsWith = [[UILabel alloc] init];
startsWith.font = self.textfield.font;
startsWith.textAlignment = self.textfield.textAlignment;
startsWith.textColor = [UIColor blackColor];
startsWith.backgroundColor = [UIColor clearColor];
startsWith.text = @"Text";
[startsWith sizeToFit];
startsWith.frame = CGRectOffset(startsWith.frame, 0, -1);
v.frame = startsWith.frame;
[v addSubview:startsWith];
self.textfield.leftViewMode = UITextFieldViewModeAlways;
self.textfield.leftView = v;
