Abstract: An electronic device with a touch-sensitive display can detect a contact with the display, and in response to detecting the contact, the device can display a user interface screen representing a corresponding application. The user interface screen can include an affordance for launching the application, and a set of information obtained from the application, where the set of information is updated in accordance with data from the application.

Abstract: The device displays a messaging user interface on a display, the messaging user interface including a conversation transcript, a plurality of electronic stickers, and a message-input area. While displaying the messaging user interface, the device detects a first user input while a focus selector is at a first location in the messaging user interface that corresponds to a first electronic sticker in the plurality of electronic stickers. In response, the device places and displays the first electronic sticker in the conversation transcript. While the first electronic sticker is displayed in the conversation transcript: the device detects a second user input while a focus selector is at a second location in the messaging user interface that corresponds to the first electronic sticker in the conversation transcript. In response, the device changes the position, size, and/or rotation of the first electronic sticker in the conversation transcript.

Abstract: A value of a display property of an affordance changes based a value of the same display property of the portion of content over which the affordance is displayed. The value of the display property of the affordance is constrained to vary within a second value range smaller than a first value range over which the value of the display property of the content is permitted to vary. A decrease of the value of the display property of the content causes an increase of the value of the display property of the affordance based on the magnitude of the value change for the content and the second value range. An increase of the value of the display property of the content causes a decreases of the value of the display property of the affordance based on a magnitude of the value change for the content and the second value range.

Abstract: An electronic device with a touch-sensitive surface, a display, and one or more sensors to detect intensity of contacts: displays a first user interface that includes objects of a first type and objects of a second type; detects a first portion of a first input that includes an increase in characteristic intensity of a first contact above an intensity threshold while a focus selector is over a respective user interface object; in response, displays supplemental information associated with the respective user interface object; while displaying the supplemental information, detects an end of the first input; and, in response: if the respective user interface object is the first type of object, ceases to display the supplemental information; and, if the respective user interface object is the second type of object, maintains display of the supplemental information after detecting the end of the first input.
