自動レイアウトを使用する Viewcontroller 内のラベルの位置を変更する必要があります。これを行う前に、私は使用しました
[arriveTimeLabel setTranslatesAutoresizingMaskIntoConstraints:YES];
[departTimeLabel setTranslatesAutoresizingMaskIntoConstraints:YES];
しかし、それはいくつかの実行時警告を生成します
Break on objc_exception_throw to catch this in the debugger.
The methods in the UIConstraintBasedLayoutDebugging category on UIView listed in <UIKit/UIView.h> may also be helpful.
2013-08-15 23:25:58.791 Vicinitime[78327:c07] Unable to simultaneously satisfy constraints.
Probably at least one of the constraints in the following list is one you don't want. Try this: (1) look at each constraint and try to figure out which you don't expect; (2) find the code that added the unwanted constraint or constraints and fix it. (Note: If you're seeing NSAutoresizingMaskLayoutConstraints that you don't understand, refer to the documentation for the UIView property translatesAutoresizingMaskIntoConstraints)
(
"<NSLayoutConstraint:0x9173a20 UIScrollView:0x9580190.bottom == UIView:0x9173890.bottom>",
"<NSLayoutConstraint:0x9171fe0 V:|-(138)-[UILabel:0x958cf70] (Names: '|':UIScrollView:0x9580190 )>",
"<NSLayoutConstraint:0x91739a0 V:|-(0)-[UIScrollView:0x9580190] (Names: '|':UIView:0x9173890 )>",
"<NSAutoresizingMaskLayoutConstraint:0xab6ec90 h=--& v=&-& UILabel:0x958cf70.midY == -6.3989*UIScrollView:0x9580190.height>",
"<NSAutoresizingMaskLayoutConstraint:0xab6eef0 h=--& v=&-& V:[UILabel:0x958cf70(25)]>",
"<NSAutoresizingMaskLayoutConstraint:0xab6dbd0 h=--& v=--& V:[UIView:0x9173890(455)]>"
)
Will attempt to recover by breaking constraint
<NSLayoutConstraint:0x9171fe0 V:|-(138)-[UILabel:0x958cf70] (Names: '|':UIScrollView:0x9580190 )>
だから私は周りを見回して、その問題を解決するには [arriveTimeLabel setTranslatesAutoresizingMaskIntoConstraints:NO]; を設定する必要があることを知りました。[departTimeLabel setTranslatesAutoresizingMaskIntoConstraints:NO];
いいえ。問題は、ラベルの位置がプログラムによって変更されないことです。
プログラムでラベルを設定するためにコーディングする必要がある場合:
if(travelTimeInt <= activityTimeInt){
[timeBreakdownButtonImage setBackgroundImage:[UIImage imageNamed:@"timeBreakdownBackground7.png"] forState:UIControlStateNormal];
NSLog(@"got to setting label place");
[self.arriveTimeLabel setFrame:CGRectMake(67, 170, 41, 25)];
[self.departTimeLabel setFrame:CGRectMake(211, 170, 41, 25)];
}
if(travelTimeInt * 7 >= activityTimeInt){
[timeBreakdownButtonImage setBackgroundImage:[UIImage imageNamed:@"timeBreakdownBackground6.png"] forState:UIControlStateNormal];
NSLog(@"got to setting label place");
self.arriveTimeLabel.frame = CGRectMake(71, 170, 41, 25);
self.departTimeLabel.frame = CGRectMake(207, 170, 41, 25);
}
autolayout をオンにして uilabel の位置を変更する方法はありますか? おそらく自動レイアウトを無効にしますか?
