UIButton在不同狀態(被點擊\正常狀態\不可用\ ...)標題是可以不同的
按鈕的狀態
typedef NS_OPTIONS(NSUInteger, UIControlState) {
UIControlStateNormal = 0,
UIControlStateHighlighted = 1 << 0, // used when UIControl isHighlighted is set
UIControlStateDisabled = 1 << 1,
UIControlStateSelected = 1 << 2, // flag usable by app (see below)
UIControlStateFocused NS_ENUM_AVAILABLE_IOS(9_0) = 1 << 3, // Applicable only when the screen supports focus
UIControlStateApplication = 0x00FF0000, // additional flags available for application use
UIControlStateReserved = 0xFF000000 // flags reserved for internal framework use
};以下代碼獲取正常狀態下的標題,并賦值給別的變量
UIControlStateNormal為正常狀態
- (IBAction)buttonPressed:(UIButton *)sender {
NSString *title = [sender titleForState:UIControlStateNormal];
NSString *plainText = [NSString stringWithFormat:@"%@ button pressed.", title];
_statusLable.text = plainText;
